The above-described disk reading device 2 can be loaded with one or a plurality of CD-ROMs 1.
Reading of map data from the D-ROM 1 is performed.
The operation panel 3 includes a route guidance mode key used for setting the route guidance mode, a destination input key, left, right, up, and down cursor keys used for inputting a via intersection, keys for map search and enlargement / reduction, and display. A setting key or the like for fixing an item at a cursor position on the screen is provided. The operation panel 3 includes, in addition to various keys provided on the front surface of the housing of the navigation device, a remote control unit capable of giving an operation instruction by infrared rays or the like. The user can appropriately select whether to operate the various keys provided in.

The vehicle position detecting device 4 detects a vehicle position and a vehicle azimuth by self-contained navigation using a speed sensor or a direction sensor or satellite navigation using GPS or the like, and uses a hybrid navigation that combines these self-contained navigation and satellite navigation. Thus, the position and direction of the vehicle may be detected with high accuracy. Also, when only GPS satellite navigation is used, the vehicle direction cannot be directly detected.
Navigation controller 1 based on two vehicle positions
The vehicle direction is obtained by calculation using 0.

The liquid crystal display device 5 displays, based on a video signal output from the navigation controller 10, map information around the own vehicle together with the own vehicle position mark, departure point mark, destination mark, via intersection mark, and the like. And a guidance route is displayed on this map. Further, the liquid crystal display device 5 displays a predetermined registration / selection screen in order to register a user name of the navigation device of the present embodiment or to select one of a plurality of registered users. I do. A specific example of the registration / selection screen will be described later.

The above-described navigation controller 10
The buffer memory 11, the map image drawing unit 13, and the like create various images to be displayed on the liquid crystal display device 5 based on the map data read from the CD-ROM 1 and convert the created images into video signals. Guidance route drawing section 19, intersection traveling guidance image drawing section 20, first and second V-RAMs 21, 22, combining section 23, video converting section 24.
In order to perform predetermined route guidance or route display based on destination data input from the operation panel 3 or vehicle position data detected by the vehicle position detection device 4,
It has a cursor position calculation unit 12, a route calculation unit 14, a route information memory 15, a distance calculation unit 16, an existing link detection unit 17, a passage determination unit 18, and a destination input unit 25.

The buffer memory 11 is for temporarily storing map data read from the CD-ROM 1 by the disk reader 2. The cursor position calculator 12 calculates and outputs cursor position data corresponding to a cursor operation on the operation panel 3.

Before starting traveling, the map image drawing section 13 stores desired map data selected by a map search key or an enlargement / reduction key on the operation panel 3 from the CD-ROM 1 by the disk reading device 2 into the buffer memory 11. And draws a map image for one screen on the first V-RAM 21 with the north direction facing upward (or the vehicle traveling direction facing upward). When any of the cursor keys on the operation panel 3 is pressed when the map image thus drawn is displayed, the map image drawing unit 13 stores new map data in the CD-ROM 1 as necessary. From buffer memory 1
1, the map image in the first V-RAM 21 is updated so that the cursor position is always at the center of the screen, and a predetermined cursor mark is drawn at the center of the screen. In addition, the map image drawing unit 13 appropriately stores new map data in the CD-ROM as the vehicle position data and the vehicle azimuth data output from the vehicle position detection device 4 change during traveling.
1, the current vehicle position becomes the center of the screen,
In addition, drawing is performed while rewriting the map image in the first V-RAM 21 so that the north direction or the traveling direction of the vehicle is directed upward, and a departure point mark, a destination mark, a waypoint mark, and the like are drawn at corresponding locations on the display screen. .

The route calculation unit 14 controls the operation panel 3 before starting traveling.
When the route guidance mode setting key is pressed to enter the route guidance mode, the cursor on the display screen is adjusted to the desired destination by the cursor operation of the operation panel 3 and the destination input key is pressed at that time. And the vehicle position data detected by the vehicle position detection device 4 at that time are stored in the route information memory 15 as destination data and departure point data. Further, the route calculation unit 14 controls the operation panel 3 in the above-described route guidance mode.
When the intersection input key is pressed after the cursor at the center of the display screen is set to the desired intersection by the cursor operation, the node table and the intersection configuration node list stored in the buffer memory 11 are referenced, The route intersection node corresponding to the intersection closest to the output of the cursor position calculation unit 12 and the route intersection configuration node, which is a set at the other end of the link with the route intersection node at one end, are route information as route intersection data. It is stored in the memory 15.

FIG. 2 is a diagram showing a part of the map data stored in the buffer memory 11. In the figure, the road list RDLT includes data such as the type of road, the total number of nodes forming roads, the positions of nodes forming roads on the node table NDTB, and the width to the next node for each road. I have. The intersection configuration node list CRDT is
For each intersection on the map, it is a set of positions on the node table NDTB of the other end node (referred to as an intersection configuration node) of the link connected to the noted intersection. The node table NDTB is a list of all nodes on the map, and includes position information (longitude and latitude) for each node, an intersection identification flag indicating whether or not the node of interest is an intersection, and an intersection configuration node list CRDT for an intersection. If it is not an intersection, it includes a pointer indicating the position of the road to which the node of interest belongs on the road list RDLT. The above-described route calculation unit 14 calculates the route intersection data by referring to the node table NDTB and the intersection configuration node list CRDT shown in FIG.

In this way, all of the transit intersections can be designated by the user. However, by simply designating a destination and a departure point or several transit intersections and transit points in addition to these, the route on the way is automatically determined. Can also be set manually. In this case, the route calculation unit 14 determines that the distance between the departure point and the destination or the route connecting several transit points in addition thereto is the shortest or that the required time is the shortest. Is calculated, and the route intersection data obtained by the calculation is stored in the route information memory 15.

The route information memory 15 stores a route intersection node and a route intersection configuration node for each route intersection in the order set by the user or in a predetermined order obtained by the automatic route search. For example, when the intersections CP1 to CP3 are set as the first to third intersections in consideration of the traveling route shown in FIG. 3, each route intersection data is stored in the route information memory 15 as shown in FIG. Is done. It should be noted that a passing identification flag PF is set for a passing intersection through which the vehicle has passed. As described above, the route information memory 15 stores
Departure place data and destination data are stored.

The distance calculation unit 16 sets a non-passing transit intersection closest to the departure point among the transit intersections as a guidance target intersection, and calculates a distance between the guidance target intersection and the vehicle position detected by the vehicle position detection device 4. calculate. Existence link detector 1
7 is map data stored in the buffer memory 11;
Based on the vehicle position data and the vehicle direction data detected by the vehicle position detection device 4, the node closest to the vehicle (forward node) existing ahead of the vehicle in the traveling direction on the traveling road and the traveling of the vehicle A pair with the node closest to the vehicle (rear node) existing behind in the direction is detected as an existing link. Based on the information stored in the route information memory 15 and the presence link data detected by the presence link detection unit 17, the passage determination unit 18 determines whether the intersection node at which the vehicle is currently heading and the rear node match. It is determined whether or not the route information is correct, and the passage identification flag PF for the corresponding intersection in the route information memory 15 is set.

The route drawing unit 19 stores the route information memory 1
Based on the data stored in No. 5, the route that follows the departure point, the first intersection, and the second intersection, and finally connects to the destination with a polygonal line, in which the vehicles that have passed Except for this, the portion included in the map image drawn on the first V-RAM 21 is drawn so as to be superimposed on the map image using a dashed line of a predetermined color.

The intersection travel guidance image drawing unit 20 uses the intersection node and the intersection constituent node registered in the route information memory 15 for the above-mentioned guidance target intersection, and
For example, an intersection shape graphic is drawn on the V-RAM 22 with the traveling direction upward, and a line of a predetermined length is drawn from the center of the intersection shape graphic in the direction of the immediately preceding intersection and in the direction of the immediately following intersection. At the same time, the intersection traveling guidance image is drawn by overlapping the arrow in the direction of the next via intersection. Also, the intersection traveling guidance image drawing unit 20 includes the distance calculation unit 16
Based on the distance data obtained in step (1), characters indicating the distance between the current vehicle position and the guidance target intersection are displayed in a part of the intersection travel guidance image. For example, "More XXk
m ”and“ あ と m ”or a bar graph indicating the distance instead of or together with these characters.

The first V-RAM 21 has an area corresponding to one display screen of the liquid crystal display device 5, and stores a map image drawn by the map image drawing section 13. Second
The V-RAM 22 has an area corresponding to a 1/9 display screen of the liquid crystal display device 5, and stores an intersection traveling guidance image drawn by the intersection traveling guidance image drawing unit 20. The combining unit 23 controls the first V during driving in the route guidance mode.
-A second VR is added to a part of the map image stored in the RAM 21.
The intersection driving guidance images stored in the AM 22 are superimposed to synthesize an image, and the synthesized image data is output. The video conversion unit 24 converts the image data output from the synthesizing unit 23 into an analog video signal for each display line, and outputs the analog video signal to the liquid crystal display device 5.

The destination input section 25 is for directly inputting a destination without using the cursor keys of the operation panel 3. For example, by operating the operation panel 3, a telephone number, a building name, When a company name, a tenant name, and the like are input, the address of a building or a business specified by the input data is set as destination data by searching the buffer memory 11. The destination data set in this way is stored in the route information memory 15 by the route calculation unit 14 and used for automatic route search and the like. When searching for a destination by using a telephone number or the like, it is necessary to use a CD-ROM 1 in which correspondence data between a telephone number or the like and a building address or the like is stored in advance.

The navigation controller 10 shown in FIG. 1 has a user setting unit 26, a user memory control unit 27, and a user memory 28 for registering and reading out personal information of a user, in addition to the above-described configuration. Have.
The user setting unit 26 gives an instruction to register or read out various types of personal information of the user when a predetermined key of the operation panel 3 is operated. When registering or reading personal information, an image representing the contents of the personal information is drawn by the user setting unit 26 and stored in the second V-RAM 22, so that the operation of registering the personal information can be performed while looking at the display screen. ing.

The user memory control unit 27 stores various personal information set by the user setting unit 26 in the user memory 2.
8 and read out the personal information of the specific user from the user setting unit 26, the corresponding personal information in the user memory 28 is read out. For example, if the destination data is read as personal information,
This destination data is stored in the route information memory 15 via the destination input unit 25 and the route calculation unit 14.

The user memory 28 is for storing personal information of a plurality of users, and has a storage area corresponding to each user. As personal information,
User's name, history of past driving, list of destinations and points to be memorized, voice mode such as gender of voice and gender in Japanese or English, map information in direction of travel System information, such as whether to face upward or northward, is used.

FIG. 5 is a flowchart showing the operation procedure of the navigation device having the above-described configuration, and mainly shows the operation of the navigation controller 10 when a user of the navigation device is selected or newly registered. As an example, suppose that the owner of the navigation device lends only the navigation device or a vehicle equipped with the navigation device to another user,
The operation of the navigation controller 10 mainly relating to registration and reading of personal information is shown. FIG. 6 is a diagram showing a specific example of a user selection / registration screen.

When the power of the navigation device is turned on, the user setting section 26 in the navigation controller 10 first determines whether or not the rental mode is set (step 501). The rental mode is an operation mode in which the original owner lends the navigation device to another person. In order to allow the user to input whether or not the rental mode is set, the user setting unit 26 displays a part of the display screen. FIG. 6 (A)
The initial screen for selecting the rental mode is displayed as shown in FIG. When the original owner operates the cursor key on the operation panel 3 and presses the setting key in a state where the cursor mark is set to the rental mode “NO” in the display screen of FIG. Then, an instruction to permit reading and writing of data in a specific area of the user memory 28 reserved for the original owner is sent to the user memory control unit 27 (step 502).

Thereafter, the user memory control unit 27
Data can be read from and written to a specific area of the user memory 28 reserved for the original owner, and in the normal operation of the navigation device, various data set by the original owner of the navigation device are stored in the user memory 2.
The data stored in the specific area of the user memory 28 is read out and used as necessary when setting various data as necessary (step 503). For example, when the original owner uses the navigation device, when an instruction to operate the operation panel 3 to display the map data with the traveling direction upward is sent to the map image drawing unit 13, the map image Drawing unit 1
The system data corresponding to this setting is stored in a specific area of the user memory 28 in parallel with the instruction input to the user 3. When the destination data is set and stored in the route calculation unit 14 by operating the cursor keys of the operation panel 3 or inputting a telephone number or the like, the destination data is set in parallel with the storing operation. Is stored in a specific area of the user memory 28. As described above, when the original owner inputs various data such as destination data using the navigation device, the various data are stored in the user memory 28 as personal information corresponding to the original owner. Next time when the power of the navigation device is turned on, the original user can input the destination data from the personal information stored in the user memory 28 without inputting various data such as the above-mentioned destination data each time. Can be selected and used.

On the other hand, in the rental mode, that is, when the owner himself or the user who has lent the navigation device operates the cursor keys on the operation panel 3, the rental mode "Yes" in the display screen of FIG. When the setting key is pressed while the cursor mark is set to, the user setting unit 26 performs a process for selecting or registering the lent user. The user setting unit 26 is configured as shown in FIG.
When "detailed setting" in the display screen shown in (A) is designated by operating the cursor on the operation panel 3 (step 504),
It is determined whether a registered user has been selected (step 505). When the “detailed setting” in the initial screen shown in FIG.
The user selection screen shown in (B) is displayed. When one of one or a plurality of registered users is selected on the user selection screen, the user setting unit 26 is next displayed.
Sends an instruction to the user memory control unit 27 to permit reading and writing of data in a specific area of the user memory 28 reserved for the selected user (step 506).

Thereafter, the user memory control unit 27
User memory 28 reserved for the selected user
Data can be read from and written to a specific area of the navigation device. In the normal operation of the navigation device, various data set by the user are stored in the specific area of the user memory 28. The data stored in the specific area of the memory 28 is read and used (Step 507).

When a user who is not included in the user selection screen shown in FIG. 6B uses the navigation device, it is necessary to newly register the name of the user. When “name registration” in the user selection screen shown in FIG. 6B is pointed by the cursor mark and the setting key of the operation unit 3 is pressed by the new user, the user setting unit 2
6 displays the user registration screen shown in FIG. 6C, and newly registers the user name in accordance with the cursor operation of the new user (steps 508 and 509). For example, FIG.
As shown in (1), the user name can be input by appropriately selecting the alphabet (or hiragana or katakana or a kanji converted based on these).

When the registration of the user name is completed and the cursor mark is positioned on the "return" portion in the user registration screen shown in FIG. 6C and the setting key is pressed, the usage shown in FIG. The user selection screen is displayed again, and the processing after step 505 shown in FIG. 5 is repeated. On this user selection screen, a newly registered user name is added, and by selecting this added user, various data input in the subsequent normal operation are added to this new user name. Is stored in a specific area of the user memory 28.

As described above, the navigation apparatus according to the present embodiment stores the personal information of each user registered in advance in the predetermined area of the user memory 28. The user performs navigation operations such as route setting and route guidance by reading and writing his / her own personal information in the user memory 28. Therefore, careless mistaken operations cause the personal information of another person, that is, the original owner or other user, to be lost. It will not be deleted or changed. Further, even when there are a plurality of users including the original owner and the users frequently lend and borrow the navigation device, the personal information dedicated to each user is always read out from the user memory 28. It is possible to set various system data and destination data, so that the time required for data input is greatly reduced as compared with the conventional case of inputting various data each time the user changes. Can be reduced.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention.

In the above-described navigation apparatus, only the original owner has to reserve a specific area of the user memory 28 and store personal information without registering his / her name. When jointly purchasing navigation equipment, only one person can be the original owner, so register the names of all users,
Personal information of each user may be registered in a specific area of the user memory 28 corresponding to each of all users. Also, the case where the name is used as identification data for identifying personal information has been described. However, since it is sufficient that each user can be identified, a number, an appropriate character, or the like may be registered for each user. .

In the case where a plurality of users other than the owner use the navigation device, the data in the common area of the user memory 28 is appropriately rewritten by classifying the owner into a person other than the owner. You may do so. Even in this case, since the original personal information of the owner is stored in another specific area of the user memory 28, another user erroneously deletes or changes the personal information stored in this specific area. There is no such inconvenience. Specifically, FIG.
When the user setting unit 26 determines in step 501 that the mode is the rental mode, the user setting unit 26 skips the determination processing in steps 504 and 505 and selects the user selected in step 506 (in this case, The user instructs the user memory control unit 27 to read and write data in a specific area of the user memory 28 prepared for the user (the user who lends the user because the user is not selected). Thereafter, in step 507, a normal navigation operation is performed. Will be.

By the way, in the above-described navigation device, it is possible to view, delete, or change another person's personal information by pointing to the name, etc. of the other person on the user selection screen shown in FIG. 6B, for example. However, register the password for each user in advance,
Unless a correct password is input when selecting a user name, access to the corresponding user's personal information can be disabled. For example, a password is registered together with the user name on the user registration screen shown in FIG. 6C, and a correct password is input together with the selection of the user name on the user selection screen shown in FIG. 6B. Only when this occurs, the navigation operation using the personal information of the user is executed. The user setting unit 26 stores the registered password in a specific area corresponding to each user in the user memory 28 under the control of the user memory control unit 27, and stores the registered password in the user memory control unit 27 when a correct password is input. The user is allowed to read and write the personal information.

In the above navigation device,
Although the personal information of the original owner or each user is stored in a specific area divided in the user memory 28, each person can store a removable storage medium such as a nonvolatile or memory card with a backup power supply. Own and
You may store your personal information in this memory card or the like. FIG. 7 is a block diagram showing a modified example of the navigation device in which personal information is stored in a memory card. The navigation controller 10 shown in FIG.
Is modified to show a part of the configuration. As shown in FIG. 7, a memory card 30 is connected via a card slot 29 instead of the user memory 28, and the memory card 30 stores personal information of the owner of the memory card 30. Therefore, when the user of the navigation device changes, it is only necessary to insert the memory card 30 owned by each user into the card slot 29, and the personal information of each user can be reliably protected from erasure or change due to erroneous operation. it can. When the memory card 30 is used, when another user is using the navigation device, the other person's memory card 30 is pulled out of the card slot 29, so that another person's personal information can be viewed. In addition, privacy can be protected without providing a password or the like.

[0044]

As described above, according to the present invention, personal information of each user is stored in the storage means, and when any user actually uses the navigation device, the personal information of each user is stored. Since the information can be accessed, it is possible to prevent the personal information of another person from being deleted or changed by mistake in the normal navigation operation, and to protect the personal information. In addition, by setting a password corresponding to each user, since other users who do not know the password cannot see the personal information, there is no leakage of the personal information, and privacy can be protected. Further, when a storage medium such as a memory card is used as a storage means for storing personal information, each user uses only personal information stored in his / her own memory card when using the navigation device. Therefore, personal information can be protected from deletion or change, and privacy can be protected by preventing leakage of this personal information.
