  Further, the navigation system 10 includes an input device 12, and this input device 12 is a portable remote controller, and by operation thereof, necessary information is received by a receiving unit (illustrated) of a microcomputer 13 (described later). Do not send). Instead of the remote controller, a touch panel attached to a liquid crystal panel (described later) of the output device 16 from the display surface side may be used as the input device 12.

  The navigation system 10 includes a microcomputer 13, a storage device 14, a wireless communication device 15, and an output device 16. The microcomputer 13 is configured by connecting a CPU, a RAM, a ROM, and the like in addition to the receiving unit via a bus line. The microcomputer 13 is navigated by the CPU according to the flowcharts shown in FIGS. Run the program.

  The microcomputer 13 is based on the detection output of the current position detection device 11, the operation output of the input device 12, the output of the storage device 14, the output of the wireless communication device 15, and the output of the dedicated information communication system 20 (described later). Various processes such as car map display, guidance route search and route guidance are performed. The navigation program is written in advance in the ROM of the microcomputer 13 so that the microcomputer 13 can read it.

  The storage device 14 is a hard disk, and the storage device 14 stores map data including road data and traffic information data as a database that can be read out by the microcomputer 13. The wireless communication device 15 receives road traffic information from the dedicated information communication system 20 and outputs it to the microcomputer 13.

  The dedicated information communication system 20 provided in the dedicated information center performs wireless communication between the wireless communication device 15 and a road traffic information communication system (hereinafter also referred to as VICS 30) provided in the road traffic information center. “VICS” is a registered trademark of the Road Traffic Information Center.

  The dedicated information communication system 20 includes a server 21, a wireless communication device 22, and a storage device 23. The server 21 executes the server program according to the flowchart shown in FIG. The server 21 performs transmission / reception processing between the wireless communication device 15 and the VICS 30 via the wireless communication device 22 during execution of the server program. The server program is written in advance in the ROM of the server 21 so as to be readable by the server 21.

  The storage device 23 is a hard disk, and the storage device 23 stores map data including road data and traffic information data as a database so that the server 21 can read them.

  The output device 16 is a display device, and displays data necessary for the vehicle as information under the control of the microcomputer 13. The output device 16 is disposed on an instrument panel provided on the front wall of the vehicle interior of the vehicle, such as a liquid crystal panel.

  In the present embodiment configured as described above, when the microcomputer 13 starts executing the navigation program according to the flowchart of FIG. The presence or absence of a display request is determined. If there is no display request by the input device 12 at the present stage, the determination of NO is repeated in step 100 of FIG.

  In such a state, if there is a request to display a desired map by the input device 12, it is determined as YES in Step 100. Thereafter, in step 110, the map data representing the desired map (hereinafter also referred to as desired map data) is read from the storage device 14. Accordingly, the desired map data is read from the database in the storage device 14. Then, in step 120, the desired map display process is performed. Accordingly, the output device 16 displays a desired map on the screen based on the desired map data.

  When the processing in step 120 is completed as described above, destination setting processing is performed in step 130. In this setting process, the destination of the vehicle is input to the microcomputer 13 by operating the input device 12.

  Next, in step 140, route search processing is performed. Along with this, a guide route from the current position detected by the current position detection device 10 to the destination selected in step 130 is searched.

  Thereafter, in step 150, route guidance processing is performed. Accordingly, route guidance processing is performed based on the guidance route searched in step 140. This means that the vehicle travels along the guide route searched for in step 140 toward the destination selected in step 130.

  Thereafter, in step 200, it is determined whether or not the traveling history of the subject vehicle is mismatched. Here, the erroneous matching indicates a case where the traveling history of the vehicle corresponds to a traveling history other than the road set on the map data stored in the storage device 14. If the vehicle is traveling on a road set on the map data without causing erroneous matching, the determination of NO is repeated in step 200.

  On the other hand, if the subject vehicle has caused an incorrect matching, it is determined YES in step 200. Thereafter, in step 210, it is determined whether or not the travel history before the erroneous matching is a general road. Here, if the traveling history of the vehicle before the erroneous matching is a general road, it is determined as YES in Step 210. Thereafter, the first self-running data creation processing routine 300 is processed (see FIG. 3). First, in step 310, a self-running data recording process is performed. In this process, the current position of the host vehicle is acquired based on the current position detection device 11, and the current position is recorded as self-running data.

  Next, in step 311, it is determined whether or not the vehicle passes through an automatic fee collection system (hereinafter referred to as ETC). In this embodiment, this determination is made based on whether or not the vehicle is detected by ETC. At the present stage, if the subject vehicle does not pass the ETC, the subject vehicle is not detected by the ETC and it is determined as NO. Thereafter, in step 312, it is determined whether or not the free-running recording data recorded in step 310 exceeds a predetermined limit. Here, the predetermined limit is a limit such as a specified time, a specified distance, and a specified memory amount. If the free-running data at the current time does not exceed the predetermined limit, NO is determined in step 312. Thereafter, the process of step 310 is performed again.

  In step 311 mentioned above, when the said vehicle passes ETC, it determines with YES based on the detection by ETC with respect to the own vehicle. Thereafter, in step 313, attachment road recording processing is performed. In this process, based on a plurality of free-running data recorded in step 310 when it is determined in step 311 that the ETC is passed from the time when it is determined in step 200 in FIG. The travel history is recorded in the database of the storage device 14 as road data indicating the attachment road.

  Next, in step 320, a free-running data recording process is performed. In this process, a recording process similar to the self-running data recording process in step 310 described above is performed.

  Next, in step 321, it is determined whether or not the traveling history of the subject vehicle is connected to the highway. At the present time, if the traveling history of the vehicle is not connected to a road set as a highway on the map data, it is determined as NO. Thereafter, the process of step 320 is performed again.

  In step 321 described above, if the travel history of the vehicle is connected to a road set as a highway on the map data, it is determined YES. Thereafter, in step 322, highway main line recording processing is performed. In this process, the travel based on the plurality of self-run data recorded in step 320 when it is determined that the vehicle has passed the ETC in step 311 and when it is determined that the map data is connected to the highway in step 321. The history is recorded in the database of the storage device 14 as road data indicating the main highway.

  Next, at step 340, it is determined whether or not the vehicle passes the ETC. If the vehicle does not pass the ETC and is traveling on the highway, the determination of NO is repeated in step 340.

  Thereafter, when the vehicle passes the ETC, it is determined as YES in Step 340. In step 341, fee recording processing is performed. In this process, the charge from the ride IC to the exit IC is recorded.

  As described above, when the vehicle traveling on a general road passes through ETC after causing an incorrect matching, that is, when traveling on a new road connected to a highway, when it is determined as an incorrect matching The self-propelled data from the time when it is determined to pass through ETC is set as road data indicating an attachment road, and the self-propelled data from when it is determined that the ETC has passed through until it is determined to connect to the expressway is the expressway It is set as road data indicating the main line.

  Therefore, by using ETC passage as a trigger, when driving on a new road connected to an expressway, the road up to ETC passage is set as road data indicating an attachment road, and the road after passing ETC is designated as the expressway main line. It is possible to automatically create additional road data that is not set in the map data by setting the road data to be shown.

  On the other hand, in step 210 of FIG. 2 described above, if the traveling history before the erroneous matching is not a general road but a highway, it is determined as NO. Thereafter, the second self-running data creation processing routine 400 is performed (see FIG. 4). First, in step 410, a self-running data recording process is performed. In this process, a recording process similar to the self-running data recording process in step 310 described above is performed.

  Next, in step 411, it is determined whether or not the vehicle passes the ETC. If the subject vehicle has not passed the ETC, the determination is NO. Thereafter, in step 412, it is determined whether or not the free-running data recorded in step 410 exceeds a predetermined limit. If the free-running data at the current time does not exceed the predetermined limit, NO is determined in step 412. Thereafter, the process of step 410 is performed again.

  In step 411 mentioned above, if the said vehicle passes ETC, it will determine with YES. Thereafter, in step 413, highway main line recording processing is performed. In this process, based on a plurality of free-running data recorded in step 410 at the time of determination that the ETC is passed in step 411 from the determination that the erroneous matching has occurred in step 200 of FIG. The travel history is recorded in the database of the storage device 14 as road data indicating the main highway.

  Next, in step 420, fee recording processing is performed. In this process, the charge from the ride IC to the exit IC is recorded.

  Thereafter, in step 430, a free-running data recording process is performed. In this process, a recording process similar to the self-running data recording process in step 310 described above is performed.

  Next, in step 431, it is determined whether or not the travel history of the subject vehicle is connected to a general road. At the present time, if the traveling history of the vehicle is not connected to a road set as a general road on the map data, it is determined as NO. Thereafter, the process of step 430 is performed again.

  In step 431 described above, if the travel history of the subject vehicle is connected to a road set as a general road on the map data, it is determined YES. Thereafter, in step 432, attachment road recording processing is performed. In this process, the travel history based on the plurality of self-run data recorded in step 430 from the time when it is determined in step 411 to pass the ETC to the time when it is determined in step 431 that the map data is connected to the general road. Is recorded in the database of the storage device 14 as road data indicating the main highway.

  As described above, if the vehicle that was traveling on the expressway passed ETC after causing an incorrect matching, that is, if the vehicle was traveling on a new expressway, it passed the ETC when it was determined to be an incorrect match. Is determined as road data indicating the main road of the expressway, and the self-propelled data from when it is determined that the ETC has passed to when it is determined to be connected to the expressway indicates the attachment road Set as road data.

  Therefore, by using ETC passage as a trigger, when driving on a new highway, the road to ETC passage is set as road data indicating the main highway, and the road after ETC passage is road data indicating the attachment road. And road data that is not set in the storage device 14 can be automatically created.

  When the first self-running data creation processing routine 300 or the second self-running data creation processing routine 400 is completed as described above, coordinate data transmission processing is performed in step 500 of FIG. In this process, in step 200, the coordinate data of the current position of the host vehicle when it is determined that there is an incorrect matching is transmitted from the microcomputer 13 to the dedicated information communication system 20 via the wireless communication device 15.

  On the other hand, in the dedicated information communication system 20, the server 21 repeats the determination of NO in step 610 of FIG. In such a state, when the server 21 acquires the coordinate data from the wireless communication device 15 via the wireless communication device 22, it is determined as YES in Step 610.

  Next, in step 620, it is determined whether or not road data corresponding to the coordinate data acquired in step 610 is set in the storage device 23 of the dedicated information communication system 20. If road data corresponding to the coordinate data is not set in the storage device 23, it is determined as NO.

  Thereafter, in step 630, data upload request processing is performed. In this process, a transmission request for road data and toll data on the attachment road and the main highway acquired by the first self-running data creation processing routine 300 or the second self-running data creation processing routine 400 is transmitted from the server 21 by wireless communication. It is transmitted to the navigation system 10 via the device 23.

  On the other hand, in the navigation system 10, the microcomputer 13 repeats the determination of NO in step 700 of FIG. In such a state, when the microcomputer 13 acquires the upload request from the wireless communication device 22 via the wireless communication device 15, YES is determined in step 700.

  Thereafter, in step 700a, a data upload process is performed. In this process, road data and toll data on the attachment road and the main highway acquired in the first self-running data creation processing routine 300 or the second self-running data creation processing routine 400 are transmitted.

  On the other hand, in the dedicated information communication system 20, the server 21 repeats the determination of NO in step 640 of FIG. In such a state, when the server 21 receives road data and toll data on the attachment road and the highway main line from the wireless communication device 15 via the wireless communication device 22, it is determined as YES in Step 640.

  Thereafter, in step 650, map data update processing is performed. In this process, the road data set in the storage device 23 is updated based on the road data on the attachment road and the main highway acquired in step 640.

  Therefore, if the new road data automatically created by the navigation 10 is not set in the storage device 23 of the dedicated information communication system 20, the road data in the storage device 23 is automatically used using the new road data. Additional creations are possible.

In carrying out the present invention, the following various modifications are possible without being limited to the above embodiment.
(1) When the vehicle is traveling along the guide route set in step 150 described above, the vehicle travels without setting a destination, not limited to the processing of steps 200 to 700a. If so, the processing of steps 200 to 700a may be performed.
(2) The coordinate data transmission process in step 500 described above is not limited to transmitting coordinate data of the current position of the vehicle when it is determined in step 200 that there is an incorrect matching, but ETC is performed in step 311 or step 411. You may transmit the coordinate data of the said ETC at the time of determining with having passed.
(3) The coordinate data transmission process in step 500 described above is not limited to transmitting coordinate data of the current position of the vehicle every time it is determined that the matching is incorrect in step 200, but a plurality of coordinate data is transmitted at a time. May be.
