Description

  The present invention relates to a navigation device that can perform appropriate guidance when a vehicle having a so-called automatic driving function (automatic driving function) is put into practical use and traveling using the automatic driving function, It relates to a navigation method.

  Navigation devices for automobiles are widely used in general. As is well known, the navigation device is mounted on an automobile, accurately grasps the current position of the aircraft using an artificial satellite, etc., and guides the route to the destination using a map display and voice guidance. This helps the driver. Various inventions have been made for navigation devices for automobiles for the purpose of improving convenience and the like. For example, Patent Document 1 described later discloses an invention related to a navigation device that can automatically switch between a navigation function and an information output function in accordance with the traveling state without performing a special switching setting.

  Specifically, the navigation device of the invention described in Patent Document 1 determines whether or not the vehicle is traveling on a highway. If it is determined that the vehicle is not traveling on the expressway, the normal navigation function is executed to provide route guidance. If it is determined that the vehicle is traveling on the expressway, a TV image or vehicle information image is output. Execute the information output function. Even when it is determined that the vehicle is traveling on an expressway, the navigation function is executed if the distance to the service area or the interchange is less than a predetermined distance. Note that the navigation device of the invention described in Patent Document 1 has a distance between intersections and the like that require guidance, even if it is a national road or a general road, when it is determined that there is a traffic jam based on information from a vehicle speed sensor or the like. It is described that processing can be similarly performed even when the length is relatively long.

Japanese Patent Laid-Open No. 08-184458

  In the case of the navigation device according to the invention described in Patent Document 1, when the traveling road is an expressway, when the traveling road is congested, the distance between intersections that require guidance is When long, the information output function was made to function instead of the navigation function. However, even if it is said that there is no need for route guidance, outputting a TV image or vehicle information image while the vehicle is driving may cause the driver's attention to be greatly directed to the image. Therefore, it may not be preferable.

  On the other hand, in recent years, various automobiles having an automatic running function have been developed, and their practical use has become a reality. In Japan, various tests for the practical application of automobiles with automatic driving functions are being carried out by research institutions such as automobile companies and universities, and dedicated roads and lanes on which cars with automatic driving functions run. (Lane) setting is also being studied. In the United States, test operations on public roads for cars with automatic driving functions have also started.

  The automatic running function can easily realize autonomous running by simply recognizing the surrounding environment and designating a destination without bothering human hands. The autonomous running function is realized using, for example, radar technology, laser image detection and ranging technology called LIDAR (Laser Imaging Detection and Ranging), GPS (Global Positioning System), a camera, and the like. Therefore, a passenger of an automobile traveling using the automatic traveling function basically performs a driving operation only in a predetermined case such as an emergency. There is no need to do.

  Therefore, when using the automatic traveling function, it is also conceivable to output a TV image, a vehicle information image, or the like as in the invention described in Patent Document 1 described above. However, even when traveling using the automatic traveling function, the rider must perform manual driving in an emergency or the like. For this reason, it is required to be able to provide information that is useful for the rider, except for route guidance, while allowing the surrounding situation to be grasped.

  In view of the above, the present invention relates to a navigation device and a navigation method for automobiles, and an object thereof is to provide useful information that replaces route guidance when using an automatic driving function.

In order to solve the above problem, the navigation device of the invention according to claim 1 is:
Network data storage means for storing road network data for route search;
At least a receiving means for receiving an instruction input of a departure place and a destination,
Using the road network data of the network data storage means, route search means for searching a route from the departure place to the destination received through the reception means;
Current position acquisition means for acquiring the current position;
A discriminating means for discriminating whether or not the aircraft is traveling on a road using an automatic driving function;
When it is determined by the determining means that the aircraft is traveling on a road using an automatic driving function, the peripheral information of the current position acquired by the current position acquiring means, and the route searched by the route searching means And peripheral information guide means for guiding one or more of the information along the route and the peripheral information of the destination.

  According to the navigation device of the invention described in claim 1, the navigation device uses the road network data in the network data storage means to search for a route from the departure point to the destination that is received through the receiving unit. It has. In the navigation device, when it is determined that the vehicle on which the vehicle is mounted is traveling on the road using the automatic driving function, the peripheral information guide unit functions and the current position acquisition unit 1 or more of the surrounding information of the current position acquired in Step 1, information along the route searched by the route searching means, and surrounding information of the destination.

  This makes it possible to notify the surrounding information of any one or more of the traveling place, the traveling route, and the destination, so that the surrounding information can be grasped and used for own actions. . In other words, since it does not provide information that is completely unrelated to the driving of the vehicle, it is necessary to provide information on the current location, route, and destination of the vehicle while properly grasping the surroundings of the vehicle. You can receive and use it.

  According to the present invention, it is possible to realize an automobile navigation device and navigation method that can provide useful information in place of route guidance when using the automatic driving function.

  Hereinafter, an embodiment of a navigation device and a navigation method according to the present invention will be described with reference to the drawings. The navigation device and the navigation method of the present invention can be applied to a so-called stand-alone navigation device or a system-type navigation device configured through a network.

  As a stand-alone navigation device, there is a small-sized navigation device that can be easily attached to and detached from an automobile, such as an in-vehicle navigation apparatus that is fixedly used in an automobile and used as a PND (Portable Navigation Device). In addition, the system type navigation device is configured by connecting a route guidance service providing server device provided on the Internet and a terminal device such as a high-functional mobile phone terminal or a tablet PC (Personal Computer) called a smartphone via the Internet. There is something to be done.

  In the following, a case where the navigation device and the navigation method of the present invention are applied to an in-vehicle navigation device that is fixedly mounted on an automobile and used will be described as an example. In the following, the in-vehicle navigation device is simply referred to as a navigation device.

[First Embodiment]
[Outline of navigation device]
The navigation device of this embodiment is used by being fixedly mounted on an automobile having an automatic driving function. The automatic traveling function realizes autonomous traveling by simply recognizing the surrounding environment and specifying a destination by using various sensor technologies and the like. Actually, by searching and setting a route from the departure point to the destination, the vehicle automatically travels to the destination by following the route.

  In addition, when the automatic traveling function is put into practical use, it is considered that an automatic traveling road on which an automobile can travel is set using the automatic traveling function. That is, it is considered that a road that cannot be traveled using the automatic travel function and a road that can travel using the automatic travel function are classified. Therefore, the navigation device of this embodiment may grasp where the automatic travelable road is and actively use the automatic travelable road, or conversely not use the automatic travelable road. I can do it.

  As a major feature of the navigation device of this embodiment, when a vehicle equipped with the vehicle is traveling using an automatic traveling function, route guidance is given to a rider who is originally a driver. Since there is no need to do this, information other than route guidance is provided. However, if you provide TV images, etc. that have nothing to do with the driving of the car, you may not be able to take appropriate actions without being able to quickly perform manual driving in an emergency because of the concentration on TV images etc. It is thought that there is.

  Therefore, the navigation device according to this embodiment notifies one or more peripheral information of the traveling place, the traveling route, and the destination, and grasps the surrounding information while taking action on its own. So that it can be useful. In other words, since it does not provide information that is completely unrelated to the driving of the vehicle, it is necessary to provide information on the current location, route, and destination of the vehicle while properly grasping the surroundings of the vehicle. It can be received and used.

[Configuration example of navigation device]
FIG. 1 is a block diagram for explaining a configuration example of the navigation device according to the first embodiment. In the navigation apparatus shown in FIG. 1, the transmission / reception antenna 101A and the wireless communication unit 101 implement a communication function, the control unit 102 implements a function for controlling each unit of the navigation apparatus, and the storage device 103 implements an information storage holding function. The operation unit 104 is provided with a power on / off switch, several function buttons, and the like.

  The navigation device of this embodiment includes a map information DB 105, a road NWDB 106, a facility information DB 107, a destination peripheral information DB 108A, and a route along information DB 108B. The letters “DB” in these descriptions are abbreviations for “Data Base”. In FIG. 1, the character “NW” in the road NWDB 106 is used as an abbreviation for “network”.

  The map information DB 105 stores map data for displaying a city map, a road map, a wide area map, a regional map, and a national map used to show a moving route, a current position, and the like to the user. The map data for displaying a city map, road map, wide area map, regional map, and national map includes, for example, vector data, raster data, and annotation (annotation) data for drawing a map. And in the map data memorize | stored in map information DB105, the automatic driving | running | working road which is a road which can drive | works a motor vehicle using an automatic driving | running | working function is distinguishable from other roads. Specifically, the road that can be automatically driven can be shown in a different color from other roads.

  In addition, there are two types of roads that can be driven automatically: an automobile that runs with an automatic running function and an automatic running combined road that can run together with a conventional car, and an automatic running road that only cars that use the automatic running function run. There is. For this reason, the automatic traveling combined road can be distinguished from each other, for example, pink and yellow hatched lines, and the automatic traveling exclusive road is pink, for example.

  For roads that can be driven automatically and roads that are dedicated to automatic driving, symbols and map notes (map annotations) can be used to indicate that the road is a road that can be driven automatically or that is dedicated to automatic driving. . That is, the map data stored in the map information DB 105 is formed as data that can be displayed by distinguishing the road that can be driven automatically and the road that is dedicated to automatic driving from other roads.

  A road network DB (described as road NWDB in FIG. 1) 105 stores and holds road network data for automobiles (hereinafter simply referred to as network data). FIG. 2 is a diagram for explaining an example of automobile network data stored in the road network DB 106. FIG. 2A shows an example of a network. Network data consists of node data and link data. The node data represents points such as landmarks, buildings, facilities, intersections, branch points, and bending points. The link data indicates a road on which a car such as a national road or a prefectural road can pass by a line segment connecting node data. The network example shown in FIG. 2A includes four node data (N1 to N4) and four link data (L1 to L4).

  FIG. 2B shows a configuration of node data in the case of the example network shown in FIG. Each node data is associated with identification information (N1, N2,...) Of each node, latitude and longitude information indicating the position of the node, and a node type. The node type indicates whether the node portion is an intersection or a branch point. In the example shown in FIG. 2C, it is indicated that all of the nodes N1 to N4 are intersections.

  FIG. 2C shows the configuration of link data in the case of the example network shown in FIG. Each link data includes identification information (L1, L2,...) Of each link, identification information (N1, N2,...) Of nodes constituting the link, link cost, link type, number of lanes, automatic travel Related information is associated. Usually, the link cost is determined by the length (distance) of the link or the time required for traffic. The link cost is referred to when searching for a route (route) that minimizes the link cost by a so-called Dijkstra method.

  In this embodiment, in addition to the length (distance) of a link or the time required for traffic, in the case of a link corresponding to an automatic driving combined road or an automatic driving exclusive road, the link is used according to the purpose of the user. It has a mechanism to adjust the link cost of the link. That is, when it is desired to actively use the automatic traveling combined road or the automatic traveling exclusive road, the link cost of the automatic traveling combined road or the automatic traveling exclusive road can be adjusted to be low. Conversely, when it is desired to avoid the automatic traveling combined road and the automatic traveling exclusive road as much as possible, the link cost of the automatic traveling combined road and the automatic traveling exclusive road can be adjusted high.

  The link type indicates whether the link part is a national road, a prefectural road, a city road, a private road, or the like. The number of lanes is the number of lanes on the road corresponding to the link. In the case of the example shown in FIG. 2C, the basic link costs of the links L1, L2, L3, and L4 are “20”, “50”, “30”, and “35”, respectively. ing. In the link type, links L1, L3, and L4 are national roads, and link L3 is a prefectural road. Furthermore, depending on the number of lanes, link L1 and link L4 are roads of 4 lanes (2 lanes on one side), link L2 is a road of 2 lanes (1 lane on one side), and link L3 is a road of 6 lanes (3 lanes on one side). It is shown.

  In the case of this example, as shown in FIG. 2 (C), the information related to “autonomous driving”, “use lane”, “time zone”, and “other” is included. “Availability” indicates whether the link is a road on which an automobile can travel using the automatic travel function. In the “permitted” column of FIG. 2C, it is indicated that the link L1 and the link L3 are roads on which automatic driving is possible, and the link L2 and the link L4 are roads that are not roads on which automatic driving is possible.

  “Used lane” indicates which lane a vehicle can travel using an automatic travel function when the link is a road on which automatic travel is possible. In the “used lane” column of FIG. 2C, the link L1 is a lane road in which all lanes can drive an automobile using the automatic driving function, and the link L3 is automatic only in the second lane. It is shown that the road is a lane where a car can travel using the travel function.

  The “time zone” indicates a time zone in which the vehicle can travel using the automatic travel function when the link is a road where automatic travel is possible. In the “time zone” column of FIG. 2 (C), the link L1 is a road on which the automobile can be driven using the automatic driving function throughout the day, and the link L3 is automatically operated from 10 am to 5 pm. It is shown that the road is a road on which a car can travel using the travel function.

  In this example, “others” is a dedicated road on which an automobile using the automatic driving function can run when the link is a road on which an automobile using the automatic driving function can travel, or an automobile using the automatic driving function. This is information indicating whether the vehicle is a shared road where both the conventional vehicle and the conventional vehicle can run. In the “Other” column of FIG. 2C, it is indicated that the link L1 and the link L2 are common roads on which both a vehicle using an automatic driving function and a conventional vehicle can travel. Yes.

  Note that the information shown as the automatic travel related information in FIG. 2C is an example, and other various information related to automatic travel can be managed in association with the link. For example, a lane in which an automobile can be driven using the automatic driving function only for one month in September, or a lane in which an automobile can be driven using the automatic driving function on Monday, Wednesday, and Friday within one week. There is also a case of providing. In order to manage such a case, it is also possible to manage when the vehicle can be driven using the automatic driving function for each link provided with a lane capable of driving the vehicle using the automatic driving function.

  In addition, there are several levels of automatic driving functions, such as fully automatic driving functions and semi-automatic driving functions, but information indicating which level's automatic driving function a car can drive is provided for each link. It can also be managed. In addition, when restrictions, conditions, etc. when driving an automobile using an automatic driving function are provided for each link, these can be managed. As described with reference to FIG. 2, link data and node data are stored in the road network DB 106.

  The facility information DB 107 stores and holds information about various facilities that are basically available to the general public, such as public facilities, tourist facilities, leisure facilities, accommodation facilities, sights, and historic sites. This includes facilities that can be used by a large number of people, such as a membership system. FIG. 3 is a diagram for explaining an example of data stored in the facility information DB 107. As shown in FIG. 3, the facility information DB 107 stores and holds, for each facility, the latitude / longitude of the representative point, the name, the address, and the like, and the guidance information. The latitude / longitude of the representative point of each facility is for specifying the position of each facility such as the center position of each facility.

  And some examples of the data stored in the facility information DB 107 shown in FIG. 3 are as follows. That is, there is a facility whose name is “XX Castle Ruins”, the address is “XX City…”, and the type is “Historic Ruins” at the position where the latitude / longitude of the representative point is indicated by (X1, Y1). , It is recorded that the guidance information is “Mr. XX's castle. In addition, there is a facility with the name “□□ Temple”, the address “XX city…”, and the type “Famous spot” at the position where the latitude / longitude of the representative point is indicated by (X2, Y2). As a guide information, it is recorded that the temple is related to the Sengoku warlords XXX, famous for cherry blossoms, and so on. As described above, the facility information DB 107 stores a large amount of information indicating where and what facilities exist. Further, the facility information DB 107 manages data about facilities all over Japan.

  The data stored in the map information DB 105, the road network DB 106, and the facility information DB 107 are updated at a necessary timing every time a change occurs so that accurate information can be managed. In particular, the automatic travel related information is updated in real time every time a change occurs, and appropriate information can be used at all times.

  FIG. 4 is a diagram for explaining an example of data stored in the destination peripheral information DB 108A and the route along information DB 108B. As shown in FIG. 4A, the destination periphery information DB 108A stores and holds information about the destination periphery collected according to the destination input for route search. In addition to various facilities that are generally available to the general public, such as public facilities, tourist facilities, leisure facilities, lodging facilities, sights, and historic sites, destination area information includes event information and traffic regulation points such as traffic closures. Information, such as the location of troubles such as fires and accidents, is included.

  An example of data stored in the destination periphery information DB 108A shown in FIG. 4A is specifically as follows. That is, a facility (museum) whose name is “XX Art Museum”, whose address is “AA City…”, and whose type is “Sightseeing” at the position where the latitude / longitude of the representative point is indicated by (XA, YA). It exists and is recorded as guidance information such as “Under XYXY development ...”. In addition, a facility (park) where the name is “XX Park”, the address is “AA City…”, and the type is “Sightseeing” at the position where the latitude / longitude of the representative point is indicated by (XB, YB). It exists and is recorded as guidance information such as “Attached to a rose garden.” As described above, various information around the destination is collected and accumulated in the destination surrounding information DB 108A.

  As shown in FIG. 4B, the route information DB 108B stores information along the route that is searched according to the route search function of the navigation device and collected according to the route set to be used for movement. Hold. The information along the route mainly includes information that should be understood when moving along the set route, such as the location of troubles such as fires and accidents, event information, and information on traffic regulation points such as closed roads. .

  An example of data stored in the route along information DB 108B shown in FIG. 4B is specifically as follows. The first stored data are the latitude and longitude of the representative point (XX1, YY1), the name is “□□ City 1-chome…”, the event is “trouble”, and the content information is “private house fire, 9/5 6” : 50 ”. That is, this data is a private house with the name “□□ City 1-chome…” at the position indicated by latitude and longitude (XX1, YY1), and fired at 6:50 am on September 5th. Is shown to have occurred.

  The second stored data is the latitude and longitude of the representative point (XX2, YY2), the name is “□□□ ○ Dome”, the event is “Event”, and the content information is “XXX Concert 9/5” 18: 30- ”. In other words, this data is the venue where the name is “□□□ ○ Dome” at the position indicated by latitude and longitude (XX2, YY2), and the event “XXX Concert” is 18:00 on September 5th. It is shown that it will be held from 30 minutes. In this way, the route information DB 108B collects and accumulates various types of information along the route along which the vehicle will move.

  The I / F unit 109 enables transmission and reception of information between the navigation device of this embodiment and the automatic travel control unit provided on the vehicle side on which the navigation device is mounted. Specifically, an inquiry such as the distance from the automatic travel control unit provided on the automobile side to the next turning corner is transmitted to the navigation device, and the response is transmitted from the navigation device accordingly. In addition, on the set route from the navigation device to the destination, a route instruction such as a turning angle or a turning direction is transmitted to the automatic travel control unit, and a response to the route instruction is transmitted from the automatic travel control unit accordingly. . As described above, various kinds of information are exchanged through the I / F unit 109 between the navigation device and the automatic travel control unit provided on the vehicle side.

  In addition, the I / F unit 109 receives information from various sensors provided on the automobile side, supplies the information to the control unit 102, and when the current position cannot be accurately measured by the GPS function described later, Autonomous navigation can be enabled. Information from various sensors provided on the vehicle side includes various information such as speed information and steer operation information.

  The GPS antenna 110A and the GPS unit 110 implement a current position acquisition function. The touch panel 112 including the display unit 111D and the touch sensor 111S, the audio output unit 113, and the speaker 114 constitute a user interface. The display unit 111D can display a map and the current position of the vehicle, or can display necessary guidance information. Various guidance messages can be emitted through the audio output unit 113 and the speaker 114.

  The route search unit 115 searches for a route (route) based on a search condition input through the touch panel 112 using the network data of the road network DB 106 under the control of the control unit 102, and displays the search result on the display unit 111D. To display to the user. Here, the search conditions are a departure place, a destination, a waypoint, information on whether or not to use an automatically travelable road, and the like. The route search unit 115 can search a plurality of routes as usable routes, and the user selects a route suitable for his / her use from the searched routes and sets the route so as to follow the route. it can.

  Under the control of the control unit 102, the automatic traveling determination unit 116 determines whether or not the automobile on which the vehicle is mounted is traveling using the automatic traveling function. Basically, the automatic travel determination unit 116 is installed on its own machine based on notification information indicating that the vehicle is automatically traveling by the automatic traveling function provided from the vehicle-side automatic traveling control unit provided through the I / F unit 109. It is possible to determine whether or not the motorized vehicle is traveling using the automatic traveling function. However, even when the automobile is moving using the automatic driving function, for example, the vehicle may be traveling on a place other than a road such as a private land or a parking lot.

  Therefore, the automatic traveling determination unit 116 uses the automatic traveling function and, when traveling on a road where automatic traveling is possible, the vehicle on which the vehicle is mounted is traveling using the automatic traveling function. Is determined. Whether or not the vehicle is traveling on an automatically travelable road can be determined by matching the current position from the GPS unit 110 with the network data of the road network DB. If there is no automatic road setting and all public roads are roads that can be driven using the automatic driving function, as described above, the current location and the network data are used to match the current location. It may be determined whether or not is on the road.

  The information collection unit 117 receives at least a starting point and a destination, performs route search, selects a route to be used from the searched routes, sets the information to be disclosed on the Internet, Peripheral information along the destination and route is collected from the facility information DB 107. Then, the information collection unit 117 records the collected destination peripheral information in the destination peripheral information DB 108A, and records the peripheral information along the route in the route information DB 108B.

  The guidance processing unit 118 includes a surrounding guidance processing unit 118A and a route guidance processing unit 118B. When the automatic traveling determination unit 116 determines that the vehicle on which the vehicle is mounted is traveling using the automatic traveling function, the surrounding guidance processing unit 118A performs route guidance under the control of the control unit 102. Instead, it performs guidance processing for surrounding areas. This is because when traveling using the automatic traveling function, it is not necessary to perform route guidance such as a corner as described above.

  Therefore, based on the current position acquired through the GPS unit 110 at each predetermined timing, the surrounding guidance processing unit 118A, for example, provides information on facilities within a circle with a radius of 2 km centered on the current position. Extracted from the facility information DB 107 and provided to the user. In this case, information is provided by displaying facility information on a map displayed on the display unit 111D, or outputting guidance information as audio information through the audio output unit 113 and the speaker 114.

  In addition, the surrounding guidance processing unit 118A extracts information along the route to be traveled from the route information DB 108B based on the current position acquired through the GPS unit 110 at every predetermined timing and provides it to the user. To do. For example, it is possible to provide information along a route that is 1 km or more from the current position every time the vehicle travels for a predetermined time or every predetermined distance. It is possible for the user to set at what timing the information along which range of routes is output. Further, the surrounding guidance processing unit 118A extracts the surrounding information of the destination from the destination surrounding information DB 108A and provides it to the user at the timing of the instruction from the user or the timing of approaching the destination by a predetermined distance or more. A method of providing information along the route and surrounding information of the destination is performed by display output and sound output in the same manner as the surrounding information of the current position described above.

  The route guidance processing unit 118B executes route guidance (navigation) processing based on the route search result in the route search unit 115, the map data in the map information DB 105, and the current position from the GPS unit 110. Specifically, the route guidance processing unit 118B displays a map showing the searched route and the current position of the own device on the display unit 111D, and performs processing for guiding the route to the user. In this case, the route guidance processing unit 118B reads out the audio data instructing the turning corner or the like from the storage device 103 and supplies it to the audio output unit 113 as necessary, and releases the audio corresponding to this from the speaker 114. Users can be guided by sound and voice messages.

  The peripheral search unit 119 collects peripheral information such as a facility instructed by the user from the Internet or the facility information DB 107 based on the current position acquired through the GPS unit 110. Then, the peripheral search unit 119 displays the collected information on the display unit 111 </ b> D or outputs the audio through the audio output unit 113 and the speaker 114. Thereby, for example, it is possible to search for gas stations around the current position, search for restaurants, search for sightseeing spots, and the like.

  A feature of the navigation device of this embodiment is that the guidance processing unit 118 is composed of two parts, a surrounding guidance processing unit 118A and a route guidance processing unit 118B. That is, in the case of a general navigation apparatus, the route guidance processing unit 118B is provided, thereby realizing a route guidance function. However, in the case of the navigation device of this embodiment, in order to take an appropriate response even when traveling using the automatic traveling function, a peripheral guidance processing unit 118A is provided, and not the route guidance, Thus, it is possible to perform such guidance processing.

  However, it is not preferable to provide a television image or the like that attracts the attention of a rider who should be a driver in an emergency even during traveling using the automatic traveling function. Therefore, as described above, the navigation device of this embodiment includes the information collection unit 117, the facility information DB 107, the destination peripheral information DB 108A, the route along information DB 108B, and the surrounding guidance processing unit 118A. In the navigation device of this embodiment, the surrounding guidance processing unit 118A can grasp the surrounding situation and can provide information other than the route guidance and useful for the rider. .

[Guidance processing performed in the navigation device]
Next, the guidance process performed by the navigation device according to the first embodiment having the configuration described with reference to FIGS. FIG. 5 is a flowchart for explaining guidance processing executed by the navigation device of the first embodiment. FIG. 6 is a diagram showing an example of a display screen displayed in the guidance process shown in FIG. 5 is executed by the control unit 102 when an item corresponding to the guidance process is selected through the touch panel 112 from a predetermined menu displayed on the display unit 111D of the navigation device.

  The control unit 102 that has executed the process shown in FIG. 5 first executes a guide preparation process (step S101). This guidance preparation process includes (1) input reception of information necessary for route search, (2) execution of route search processing, (3) notification of route search result, and (4) target route from the route search result. Processing such as selection and setting is performed.

  (1) When receiving input of information necessary for route search, a predetermined input screen is displayed on the display unit 111D, and is necessary for route search, such as the use of a departure place, destination, waypoint, and whether or not a road capable of automatic driving is used. Various information to be received is received through the touch panel 112. It should be noted that the conventional search modes such as “toll road priority”, “general road priority”, “distance priority”, and “time priority” are also accepted. (2) In the route search process, the control unit 102 controls the route search unit 115, and the road network data in the road network DB 106 is based on the information received in the input receiving process of information necessary for the route search in (1). To search for a route from the starting point to the destination. In the route search process (2), one or more routes are searched.

  (3) In the notification of the route search result, the control unit 102 displays one or more routes searched by the route search process of (2) on the display unit 111D and notifies the user. In the notification of the route search result in (3), first, a list of information including a transit point, a required time, a travel distance, and the like is displayed for each searched route. Then, according to the user's selection operation, the route corresponding to the selected information is displayed on the display unit 111D as shown on the map so that each route can be confirmed on the map. In (4) selecting and setting the target route from the route search result, the route used for route guidance is selected and determined, and the route used for route guidance is set in the navigation device.

  Such a series of guidance preparation processing is executed in step S101. In addition, when a target route, that is, a route that matches the user's purpose cannot be searched, the search can be performed again by changing the search conditions. When a route used for route guidance is set and an operation for starting guidance is performed, the control unit 102 ends the guidance preparation process in step S101.

  Then, the control unit 102 controls the automatic traveling determination unit 116 to determine whether or not the automatic traveling function is used in the automobile on which the own device is mounted (step S102). That is, when the automatic driving function is used, the automatic driving control unit of the automobile notifies the I / F unit 109 of information indicating that the automatic driving function is used. For this reason, the automatic travel determination unit 116 depends on whether or not information indicating that the automatic travel function is used is notified from the automatic travel control unit of the car after the guidance preparation process in step S101. Then, it is determined whether or not the automatic driving function is used in the vehicle.

  When it is determined in step S102 that the automatic driving function is used in the vehicle, the control unit 102 further controls the automatic driving determination unit 116 to determine whether or not the vehicle is traveling on an automatic driving enabled road ( Step S103). In step S103, the automatic travel determination unit 116 can match the current position from the GPS unit 110 with the road network data in the road network DB 106 to determine whether the current position is on an automatically travelable road.

  When it is determined in step S103 that the host vehicle is traveling on a road on which automatic driving is possible, the control unit 102 controls the information collecting unit 117 and the surrounding guidance processing unit 118A to perform the surrounding guidance processing. Start (step S104). That is, when traveling using the automatic traveling function, it is not necessary to provide route guidance to the passenger. Therefore, guidance is provided for surrounding areas. Here, in the surrounding guidance processing, the information collecting unit 117 functions under the control of the control unit 102 and collects the surrounding information of the destination and the information along the route, and the surrounding guidance processing unit 118A functions, As described above, surrounding guidance for the current position, information guidance along the route, surrounding guidance for the destination, and the like are performed at a predetermined timing.

  Specifically, the surrounding guidance processing unit 118A displays, for example, information on an available facility located within a radius of 2 km based on the current position based on the stored data in the facility information DB 107, as a display unit 111D. It is shown on the map displayed on and provided to passengers. FIG. 6A shows an example in which peripheral information about the current position P of an automobile on which the navigation device of this embodiment is mounted is displayed.

  In the navigation device of this embodiment, as shown in FIG. 6A, for example, “XX Castle Ruins”, “XX Mountain”, and “□□ Temple” are included as peripheral information (facility information) of the current position P. It is shown on the map displayed on the display unit 111D. In this case, “XX castle ruins” is guided by the display information of the corresponding display area H1 that “the castle is disappearing in the Edo period”. Similarly, “XX mountain” is a place where hiking is possible “having a hiking course” according to the display information of the corresponding display area H2, and “□□ temple” is “Sengoku” according to the display information of the corresponding display area H3. It is said that it is a famous spot for cherry blossoms at a temple related to warlords. In this way, the surrounding guidance processing unit 118A can perform so-called sightseeing guidance around the current position P.

  In addition, the surrounding guidance processing unit 118A can also provide the user with the surrounding guidance for the destination based on the data stored in the destination surrounding information DB 108A. For example, as shown in FIG. 6B, a display area H4 for displaying the guidance for the destination is provided on the display portion 111D side where the map is displayed, and the guidance for the destination is displayed here. In the case of the example shown in FIG. 6B, the required time to the destination and the guidance that there is a XX museum around the destination and that the XYXY exhibition is being held.

  Such surrounding guidance of the destination can be performed, for example, at the timing of the operation input received from the user via the touch panel 112 or at the timing when the destination approaches a predetermined distance or less. For this reason, for example, a “destination” button for outputting the guidance of the vicinity of the destination is displayed at a predetermined position of the display unit 111D of the touch panel 112. Note that FIG. 6B is an example in the case where the surrounding guidance of the destination is provided without changing the map including the current position P, and a map of the area including the destination is displayed on the display unit 111D. In such a case, it is possible to perform guidance around the destination in the manner shown in FIG.

  The surrounding guidance processing unit 118A can also provide information along the route to the user based on the data stored in the route information DB 108B. As described above, the information along the route includes various information such as information on troubles such as traffic accidents and fires that occurred along the route, and event information performed at venues along the route. The provision of information along the route can be guided in the form shown in FIG. 6A when the guidance position is included in the map displayed on the display unit 111D. Moreover, when the position to guide is not contained in the map currently displayed on the display part 111D, it can guide in the aspect shown to FIG. 6 (B).

  Such surrounding guidance for the current position, surrounding guidance for the destination, and information guidance along the route are started in step S104. Further, in the surrounding guidance processing, which is not shown in FIG. 5, it is possible to accept an operation such as stopping or temporarily stopping the guidance processing and perform processing according to the operation. It has become.

  The surrounding guidance processing unit 118A provides not only guidance by display on the display unit 111D, but also voice guidance information about facilities that are displayed and guided on the map through the voice output unit 113 and the speaker 114. Can also be provided. In this case, the guidance information by voice can be added in advance to the data for each guidance target in the facility information DB 107, the destination peripheral information DB 108A, and the route information DB 108B as voice data, or so-called TTS (Text To Speech ) Function, it is also possible to output guidance information as character data for each guidance target using synthesized speech.

  And the control part 102 discriminate | determines whether it changed to the state which complete | finishes guidance processing, such as a periphery (step S105). In other words, the control unit 102 determines that the vehicle has been changed to a state in which the guidance processing for surroundings and the like is terminated when the vehicle on which the device is mounted is not automatically running. In addition, the control unit 102 determines that the state has been changed to a state in which the guidance process for the surrounding area is ended even when the user arrives at the destination or performs an operation to end the guidance process.

  The control unit 102 controls the automatic traveling determination unit 116 to check whether the automatic traveling function is used and the vehicle travels on a road where automatic traveling is possible. It can be determined whether or not the vehicle is running automatically. Further, the control unit 102 can determine whether or not the vehicle has arrived at the destination based on the current position detected by the GPS unit 110, and ends the guidance process based on the operation input received from the user. It is possible to determine whether or not an operation to be performed has been performed.

  If it is determined in the determination process in step S105 that the peripheral guidance process has not ended, the process from step S105 is repeated to continue the peripheral guidance process. On the other hand, when it is determined in the determination process in step S105 that the peripheral guidance processing has been changed to a state in which the peripheral guidance processing is to be ended, the control unit 102 controls the peripheral guidance processing unit 118A to end the peripheral guidance processing (step S106). ).

  On the other hand, when it is determined in the determination process of step S102 that the vehicle does not use the automatic driving function, and in the determination process of step S103, when it is determined that the own vehicle is not traveling on the road where automatic driving is possible, The process proceeds to S107. In this case, the control unit 102 controls the route guidance processing unit 118B to start route guidance (step S107). Here, the route guidance is set by indicating a map, a route, and the current position of the vehicle on the display unit 111D, which is conventionally performed by a navigation device, and instructing a turning angle and a turning direction by video and audio. This is a process of performing route guidance so as to move to the destination after moving the route.

  And the control part 102 discriminate | determines whether it changed to the state which complete | finishes a route guidance process (step S108). That is, the control unit 102 determines that the route guidance process has been changed to a state in which the vehicle on which the vehicle is mounted is automatically running. In addition, the control unit 102 determines that the route guidance process has been ended when the destination is reached or an operation for terminating the guidance process is performed.

  The basic processing content of the determination process in step S108 is the same as the determination process in step S105 described above. That is, the control unit 102 can determine whether or not the automobile on which the vehicle is mounted is automatically traveling through the automatic traveling determination unit 116. Further, the control unit 102 can determine whether or not the vehicle has arrived at the destination based on the current position detected by the GPS unit 110, and ends the guidance process based on the operation input received from the user. It is possible to determine whether or not an operation to be performed has been performed.

  If it is determined in step S108 that the route guidance process has not been terminated, the process from step S108 is repeated to continue the route guidance process. On the other hand, when it is determined in step S108 that the route guidance process has been terminated, the control unit 102 controls the route guidance processor 118B to end the route guidance process (step S109).

  Then, after finishing the surrounding guidance processing in step S106 and after finishing the route guidance processing in step S109, the control unit 102 determines whether or not the guidance processing in the own device has ended. It discriminate | determines (step S110). In this case, when the user arrives at the destination or performs an operation to end the guidance process, it is determined that the state in which the guidance process is to be ended has been entered. As described above, the guidance processing for determining whether or not the state to be ended in the determination processing in step S110 includes both the surrounding guidance processing and the passing guidance processing.

  If it is determined in the determination process in step S110 that the guidance process in the own device is not finished, the process from step S102 is repeated. As a result, when automatic driving using the automatic driving function is switched to manual driving (manual driving) by the driver, conversely, automatic driving using the automatic driving function is switched from manual driving (manual driving) by the driver. When it is switched to, appropriate guidance processing can be performed.

  On the other hand, when it is determined in the determination process of step S110 that the guidance process in the own machine has been terminated, the display on the display unit 111D is displayed before the guidance process is performed from a map display or the like for performing the guidance process. For example, a series of end processing such as returning to a predetermined menu screen is performed (step S111), and the guidance processing shown in FIG. 5 is ended.

[Effect of the first embodiment]
As described above, the navigation device according to the first embodiment is replaced with normal route guidance when the vehicle on which the vehicle is mounted is traveling on an automatically travelable road using the automatic travel function. Can guide the surroundings. Here, the guidance for the surrounding area includes the surrounding guidance for the current position, the information guidance along the route, the surrounding guidance for the destination, and the like. That is, the navigation device according to the first embodiment can provide useful information in place of route guidance when the automatic travel function is used.

  The useful information that can be provided is not information that has nothing to do with the driving of the vehicle, but is information on the periphery of the current position, information on the route, information on the periphery of the destination, and the like. For this reason, it is possible to receive and provide information on the current location, route, and destination of the vehicle while appropriately grasping the situation around the vehicle.

[Second Embodiment]
In the first embodiment described above, guidance processing such as surroundings is performed during automatic traveling. Then, for example, it is considered that there may be a case where it is desired to perform a peripheral search or to find a facility where the user wants to stop by using the peripheral guidance of the current location. In such a case, for example, it is conceivable that the automobile is stopped once and the vicinity search is performed, or the destination is changed and a new route search is performed so as to go to the destination.

  However, when traveling using the automatic traveling function, it may be possible to execute the vicinity search. In addition, although the final destination is not changed, it may be possible to detour to the facility guided by the surrounding guidance. For this reason, in the navigation device of the second embodiment, when guidance processing such as surroundings is performed, it is possible to perform a detour without performing a peripheral search or changing the final destination. To be able to.

  The navigation device according to the second embodiment is configured in the same manner as the navigation device according to the first embodiment described above. For this reason, the navigation apparatus of the second embodiment will also be described as having the configuration shown in FIGS. In the case of the navigation device according to the second embodiment, the surrounding guidance processing is different from that in the first embodiment described above.

  FIG. 7 is a flowchart for explaining the guidance processing performed in the navigation device of the second embodiment. As can be seen from a comparison between FIG. 7 and FIG. 5 described above, the parts other than the surrounding guidance processing executed in step S200 are the guidance processing performed in the navigation device of the first embodiment shown in FIG. The same processing is performed.

  For this reason, in the guidance process of the second embodiment shown in FIG. 7, the same reference numerals are given to the processes (steps) performed in the same manner as the guidance process shown in FIG. Since the description is duplicated, it will be omitted. Then, as can be seen by comparing the processing shown in FIG. 7 with the processing shown in FIG. 5, the guidance processing shown in FIG. 7 of the second embodiment is also the first described with reference to FIG. Similar to the guidance process of the embodiment, the surroundings guidance process is performed when the vehicle is traveling on an automatically travelable road using the automatic travel function. If the vehicle is not traveling using the automatic traveling function, or if the vehicle is traveling using the automatic traveling function but is not traveling on the road where automatic traveling is possible, the conventional route guidance process ( Navigation processing).

  In the navigation device according to the second embodiment, guidance processing such as surroundings executed when traveling on a road where automatic driving is possible using the automatic driving function is the same as that of the first embodiment. It is different from the case. FIG. 8 is a flowchart for explaining the surrounding guidance process executed in step S200 shown in FIG. FIG. 9 is a diagram showing an example of a display screen used in the surrounding guidance process of FIG.

  In step S200 shown in FIG. 7, a guidance process for surroundings shown in FIG. 8 is executed. In this case, as shown in FIG. 8, the control unit 102 first controls the information collection unit 117 and the surrounding guidance processing unit 118A to start the surrounding guidance processing (step S201). The processing in step S201 is similar to the processing in step S104 shown in FIG. That is, under the control of the control unit 102, the information collecting unit 117 functions to collect the peripheral information of the destination and the information along the route, and the peripheral and other guidance processing unit 118A functions to provide the peripheral guidance and route of the current position. Start information guidance along the way, around the destination.

  Thereafter, in the case of the navigation device according to the second embodiment, the control unit 102 displays operation buttons for executing these processes in order to enable execution of the peripheral search process and the detour process. It is displayed on 111D (step S202). For example, as shown in FIG. 9A, it is assumed that the surrounding guidance for the current position is displayed on the display unit 111D and the surrounding guidance for the current position is performed. In this case, the control unit 102 includes a “peripheral search” button B1 for executing a peripheral search process on the lower right side of the display screen displayed on the display unit 111D and a “detour” for executing the detour process. Button B2 is displayed to allow the user to operate.

  And the control part 102 receives the operation input with respect to the operation button for enabling execution of a periphery search process and a detour process through the touch panel 112 (step S203). The user of the navigation device according to the second embodiment taps the “surrounding search” button B1 on the touch panel 112 when performing the surrounding search process. Also, when executing the detour process, the user taps on the “detour” button B2 through the touch panel 112 after performing a tap operation on a location that is the destination of the detour on the displayed map. . Then, the control unit 102 determines whether or not the execution of the peripheral search process is instructed through the touch panel 112 (Step S204).

  When it is determined in the determination process of step S204 that execution of the peripheral search process is not instructed, the control unit 102 determines whether or not execution of the detour process is instructed (step S205). When it is determined in the determination process of step S205 that execution of the detour process is not instructed, the control unit 102 determines whether or not the state has been changed to a state in which the surrounding guidance process is terminated (step S206). The discrimination process in step S206 is the same as the discrimination process in step S105 shown in FIG. In other words, in step S206, the control unit 102 determines that the surrounding guidance process has been completed when the vehicle on which the vehicle is mounted is not in automatic travel. Further, in step S206, the control unit 102 determines that the state has been changed to the state where the guidance process such as the surroundings is ended even when the destination is reached or an operation for terminating the guidance process is performed.

  When it is determined in step S206 that the surrounding guidance process has not been finished, the control unit 102 repeats the process from step S203 and continues the surrounding guidance process. On the other hand, when it is determined in the determination process in step S206 that the peripheral guidance process has been finished, the control unit 102 controls the peripheral guidance process unit 118A to end the peripheral guidance process (step S207). ). The process of ending the surrounding guidance in step S207 is the same as the process in step S106 shown in FIG. Thereafter, the control unit 102 ends the guidance process routine for surroundings shown in FIG. 8, returns to the process in FIG. 7, and determines whether to end the guidance process itself (step S110).

  On the other hand, when it is determined in the determination process of step S204 that execution of the peripheral search process is instructed (the “peripheral search” button is operated), the control unit 102 executes the peripheral search process (step S208). In step S208, the control unit 102 first displays a keyword input screen for searching around as shown in FIG. 9B and accepts keyword input. Then, the control unit 102 controls the surrounding search unit 119, refers to the facility information DB 107, extracts facility information that matches the keyword, and displays this on the display unit 111D as a list. The list can be scrolled if it cannot be displayed on the display 111D. The vicinity searching unit 119 can also search for information around the current position corresponding to the keyword from information disclosed on the Internet.

  In step S208, when the user taps the display column for information related to the target facility, the control unit 102 controls the surrounding guidance processing unit 118A to determine the location of the facility. A map of the included area is displayed on the display unit 111D. In this case, the map is displayed in the form shown in FIG. 9A, and the “surrounding search” button B1, the “detour” button B2, and the “return” button (not shown) are displayed. Operation on the button is accepted. Then, the control unit 102 receives an operation input for any of the “surrounding search” button B1, the “detour” button B2, and the “return” button, and determines whether or not the “return” button has been operated (step S209). .

  When it is determined in step S209 that the “return” button has been operated, the control unit 102 returns the display on the display unit 111D to the original state, for example, the display of the surrounding guidance of the current position (step S210). The processing from step S203 is repeated. That is, the process returns to the surrounding guidance process. If it is determined in step S205 that the “return” button has not been operated, the processing from step S204 is repeated. As a result, it is possible to further perform a peripheral search or to perform a detour to a facility (location) found by the peripheral search.

  When it is determined in the determination process of step S204 that execution of the peripheral search process is not instructed, the control unit 102 determines whether or not execution of the detour process is instructed (step S205). In the determination process of step S205, when it is determined that execution of the detour process is instructed, the control unit 102 executes the detour process (step S211). In the detour process in step S211, in step S203 or step S208, the position on the displayed map is used as a detour destination, a route search from the current position to the destination of the detour is performed, and guidance to the destination is performed. Process. In other words, the processing shown in FIG. 5 is executed with the departure point as the current position and the destination as the destination of the designated detour.

  By the process of step S211, guidance processing such as surroundings is performed when a detour is performed using an automatic travel function by an automobile equipped with the navigation device, and when a detour is performed by manual travel, a route is performed. Guidance processing can be performed. In this way, the user finishes the guidance process one by one, and without having to input necessary information from the beginning and make a detour, instruct the destination of the detour on the map and tap the “detour” button You can make a detour just by doing. When the user arrives at the destination of the detour or when the end operation of the detour process is performed by the user, the destination is returned to the original destination and so-called reroute processing is performed (step S212).

  In the reroute process of step S212, the departure point is set as the current position, and the original destination input in the process of step S101 in FIG. However, for example, the initial route search conditions can be used or can be changed for the search conditions such as the waypoints and the use / non-use of the road on which automatic driving is possible. Then, after the reroute process of step S212, the surrounding guidance process started in step S201 is terminated, and the process returns to the process shown in FIG. Appropriate guidance processing can be continued according to the travel location.

[Effect of the second embodiment]
As described above, in the case of the navigation device according to the second embodiment, when the vehicle is traveling using the automatic traveling function, the surrounding search process can be performed. In addition, even when you detour to the target location found by surrounding guidance or surrounding search processing of the current position, appropriate guidance processing is performed according to the state of the car on which the aircraft is installed without complicated operations. It can be performed.

  Further, even when a detour is made on the way to the initial destination, the navigation device of the second embodiment can be made to function so as to automatically go to the initial destination. As a result, functions not available in the conventional navigation device considering the use of the automatic driving function can be realized, and the convenience for the user can be improved.

[Modification]
Moreover, although the navigation apparatus of embodiment mentioned above demonstrated as an example the case where it applied to the vehicle-mounted navigation apparatus fixedly mounted and used for a motor vehicle, it does not restrict to this. The present invention can also be applied to a small-sized navigation device called a PND that is similarly configured and that can be easily attached to and detached from an automobile.

  The present invention can also be applied to a system-type navigation device configured by connecting a route guidance service providing server device provided on the Internet and a terminal device such as a smartphone or a tablet PC through the Internet. In this case, the route guidance service providing server device (hereinafter simply referred to as a server) includes a map information DB 105, a road network DB 106, a facility information DB 107, and a destination peripheral information DB 108A among the configurations of the navigation device shown in FIG. The route information DB 108B, the route search unit 115, the information collection unit 117, and the surrounding search unit 119 are provided. The terminal device is provided with other parts.

  Then, a route search request is transmitted from the terminal device to the server, and the route search is performed on the server side. Then, the terminal device receives the route search result from the server and sets the route to be used. Furthermore, the terminal device requests the server to provide map data and data used for guidance required when following the set route, receives the provision from the server, and guides the surroundings and route guidance processing. Can be executed.

  Also, in the surrounding guidance process, various surrounding information such as geographical information, sightseeing information, trouble information such as a fire or traffic accident can be guided as surrounding information of the current position. In addition, various information such as geographical information, tourist information, trouble information such as fires and traffic accidents, and event information can be provided for the peripheral information of the destination and information along the route. In addition, it is possible to provide information such as traffic information along the route, weather forecast, and weather forecast for the destination. For trouble information, event information, traffic information, weather forecast, etc., those disclosed on the Internet can be used.

  In addition, when the user selects and sets what information is to be guided at what timing, the user is guided to the necessary information at the necessary timing during the surrounding guidance processing. be able to.

  In the above-described embodiment, the information other than the route guidance is output and the route guidance information is output. However, the present invention is not limited to this. For example, during automatic traveling, route guidance information can be output together with information other than route guidance. In this case, both the guidance processing unit 118A around the guidance processing unit 118 of the navigation device and the route guidance processing unit 118B function.

  In this way, by outputting the route guidance information together with the information other than the route guidance, it is possible to obtain information other than the route guidance while confirming the route to be originally traveled. You can be in the car with a sense. In addition, when outputting route guidance information together with information other than route guidance, the output frequency of route guidance information may be reduced, or route guidance information may be output at a route change point such as an intersection. it can. Thereby, information other than route guidance can also be used appropriately.
