An example of a hardware configuration of the processing operation unit 2 will be described with reference to FIG.

In this embodiment, the arithmetic processing unit 2 is constructed by connecting each of the devices 31 to 40 in the figure with a bus.
Each component includes a CPU 31 for executing various processes such as numerical operations and controlling each device, a RAM 32 for storing map data, route data, guidance information, etc., a ROM 33 for storing processing programs and data, a high-speed memory and a memory.

9. A counter 40 for integrating the pulse signal.

The functional configuration of the processing operation unit 2 realized by the above-described hardware configuration will be described with reference to FIG.

The user operation analysis section 41 analyzes the contents of the request from the user received by the input device 4, and controls each unit to execute a corresponding process.

The current position calculating unit 42 uses the distance data and the angle data obtained as a result of integrating the distance pulse data S5 measured by the wheel speed sensor 6 and the angular acceleration data S7 measured by the gyro 8, respectively, Is integrated on the time axis to calculate the position (X ′, Y ′) after traveling of the moving object from the initial position (X, Y). here,
In order to match the relationship between the angle of rotation of the moving body and the direction of travel, the direction data S6 obtained from the geomagnetic sensor 7 and the angle data obtained by integrating the angular acceleration data S7 obtained from the gyro 8 are mapped into a one-to-one relationship. The absolute azimuth of the direction in which the moving body is traveling is corrected. In addition, since the error of the sensor accumulates when the data obtained from the sensor is integrated, a process of canceling the accumulated error based on the position data S8 obtained from the GPS receiver 9 in a certain time period is performed. The current position information is output.

Since the current position information includes an error of the sensor, for the purpose of further improving the position accuracy,
The map matching section 43 performs a map matching process. This is because the road data included in the map around the current location is read from the storage device 5 by the map data reading unit 44, and the travel locus shape and the road shape obtained from the current position calculation unit 42 are illuminated with each other. This is the process of adjusting the current location to a high road. By performing the map matching process, the current position often coincides with the traveling road, and the current position information can be output with high accuracy.

The route search unit 46 uses a Dijkstra algorithm or the like to find the shortest distance route between any two points on the network, and the shortest distance route from the current position to the destination or the shortest time route taking traffic information into account. The route is calculated using the road data read by the map data reading unit 44.

The connection detecting section 45 is means for detecting whether the portable terminal 20 is connected to or disconnected from the communication I / F 11. Specifically, for example, a control command for detecting the connection is periodically transmitted to the mobile terminal 20 via the communication control unit 47, and when a response corresponding to the control command is returned, it is determined that there is a connection, and the response is determined. If not returned, it is determined that the connection is not established.

As another detecting means, a communication I / F 1
By mounting a means for mechanically or electrically detecting the connection of the communication cable or the communication port as hardware in 1, the connection state can also be detected.

It is not necessary for the user to input a command to start communication by mounting the detection means as described above and performing control so as to immediately execute communication when the connection state is detected by the detection means. Thus, the effect that the operation can be simplified can be obtained.

The communication control unit 47 performs transmission / reception processing of a communication control command and telephone number information including at least a telephone number as a component according to a prescribed communication protocol.

The guide information search unit 48 searches for guide information composed of the telephone number stored in the storage device 5 and the position information corresponding to the telephone number, and the position information corresponding to the telephone number included in the telephone number information is used as a guide. It is determined whether the information is stored. When it is determined that the information is stored in the guidance information, the guidance information such as position information, name, and facility type corresponding to the telephone number is stored in the RAM 32 in the arithmetic processing unit 2.

The destination setting section 51 displays a setting method selection screen for selecting an arbitrary destination setting method, and performs a process of determining a destination according to the destination setting method selected by the user.

The map display section 49 includes a map data reading section 44.
The rotation and scale conversion are performed on the road, background, name data, and the optimal route searched by the route searching unit 46 to generate drawing data.

The telephone number information erasing section 50 erases the telephone number information stored in the RAM 32 at a predetermined timing. The timing of the deletion is, for example, when a state where the ignition switch is turned off via the in-vehicle LAN device 10 is detected. Further, the received telephone number information may be deleted at the timing when the connection detection unit 45 detects the disconnection from the mobile phone 20. Furthermore, a menu screen for deleting a telephone number may be displayed, and the telephone number information may be deleted according to a user's instruction.

By erasing the telephone number information stored in the RAM 32 using these methods, it is possible to prevent the telephone number information from being used by anyone other than the user. Further, the contents to be deleted may be the telephone number information stored in the RAM 32, and the telephone number information not selected as the destination or the waypoint may be selected and deleted. As a result, even when the ignition switch is turned off during a temporary break or the like, the most important destination or waypoint information is stored, so that the route guidance can be continuously executed.

The display processing section 52 develops the drawing data generated by the map display section 49 and the destination setting section 51 into an image in the VRAM 35 and causes the output device 3 to display it.

FIG. 4 is a diagram showing an example of a processing flow of the communication control unit 47 executed when the connection state is detected by the connection detection unit 45.

Next, guidance information identification processing (step 71)
Then, the area / city station number stored in the storage device 5 and the representative position information of the area covered by the area number are searched, and it is determined whether the area number / city station number matches the read telephone number. If the matching area / city code is stored, the fixed station is determined.If the matching area / city code is not stored, the mobile station is determined to be the phone number. The information is stored in the RAM 32 in association with the number information. In order to determine the mobile station, the mobile station and the fixed station may be identified by determining whether a station number unique to the mobile station is added to the telephone number. Here, if it is determined that the mobile station, the process proceeds to step 73.

Further, if the read telephone number is a telephone number of a fixed station, the guidance information stored in the storage device 5 is searched, and it is determined whether or not the read telephone number completely matches the read telephone number. If the phone numbers match exactly, go to step 72,
If they do not match, the process transitions to step 73.

In the related information setting process (step 72),
The location information and the related information such as the name information, the facility information, the location information, and the address information corresponding to the coincident telephone number are read out from the storage device 5, and the RAM is associated with the telephone number information.
32. Thereby, the position information and the related information corresponding to the telephone number are uniquely associated.

In the end determination processing (step 73), it is determined whether or not the search processing has been executed for all the received telephone numbers.
Control is performed such that the process of 72 is repeated.

FIG. 6 is a diagram showing an example of a processing flow in the destination setting section 51. Hereinafter, the details will be described in accordance with the processing flow.

In this processing flow, first, in the setting means selection screen display processing (step 90), a setting means selection screen used by the user to select a means (method) for setting a destination or a waypoint is output to the output device 3. indicate. In this step, for example, character strings such as “input map”, “direct input of telephone number”, and “input telephone number list” are displayed on the display screen, and a selection regarding any one of these character strings is received from the user. Have the user select the input method to be used.

In the means judging process (step 91), the process is shifted to the selecting means designated by the user from the destination setting method displayed on the setting means selecting screen. For example, "
If "input map" is selected, "input telephone number list" is selected in the map setting processing (step 92), and if "direct telephone number input" is selected, "input telephone number list" is selected in the telephone number direct input processing (step 93). If so, the flow branches to a telephone number list input process (step 94).

Here, the branch destination is set in a map setting process (step 92) and a telephone number direct input process (step 9).
3) Although the processing is limited to the telephone number list input processing (step 94), a selection method using specific attribute information such as a facility attribute may be further provided to branch.
