For example, a configuration in which various types of sensors 315 are used to determine the vehicle traveling may be used.

  In step S501, after waiting for the vehicle to travel, if the vehicle is traveling (step S501: Yes), the communication I / F 313 then receives toll road usage information from the ETC roadside machine. It is determined whether or not it has been done (step S502). The toll road usage information is information on toll road usage including, for example, a toll road travel section and usage fee.

  In step S502, when toll road usage information is not received from the ETC roadside device (step S502: No), the process proceeds to step S507, and it is determined whether a request for a route search is accepted by the input device 310 (step S502). S507).

  In step S502, when toll road usage information is received from the ETC roadside device (step S502: Yes), the toll road usage information is subsequently obtained by the CPU 301 based on the output information of the GPS unit 314 and various sensors 315. The received use information reception position is detected (step S503).

  Subsequently, the CPU 301 controls the magnetic disk drive 304 to read map information recorded on the magnetic disk 305 (step S504). In the description of FIG. 5, the map information is recorded on the magnetic disk 305. However, the map information may be recorded on a recording medium such as the optical disk 307 or other memory or an external device. In addition, when it records on the exterior of the navigation apparatus 300, map information is acquired via a network via communication I / F313.

  Then, it is determined whether or not the usage information reception position detected in step S503 by the CPU 301 has been registered as toll road entrance / exit information (step S505). Specifically, for example, it is determined whether there is an entrance / exit of a toll road registered in the map information around the usage information reception position.

  In step S505, when it has been registered as entrance / exit information (step S505: Yes), the process proceeds to step S507, and it is determined whether or not a route search request has been received by the input device 310 (step S507).

  In step S505, when it is not already registered as entrance / exit information (step S505: No), the CPU 301 registers the use information reception position in the map information as entrance / exit information of the toll road (step S506). The entrance / exit information relates to, for example, the location information of the entrance / exit of the toll road at the use information receiving position detected in step S503, and the use fee associated with the use section when using the toll road entrance / received received in step S502. Information including information.

  Further, the registration to the map information may be, for example, by editing the map information recorded on the magnetic disk 305 by controlling the magnetic disk drive 304. More specifically, the usage information reception position is registered in association with map information as entrance / exit information of toll roads. Further, the usage information reception position as the toll road entrance / exit information may be registered in a recording medium such as a memory (not shown) separate from the magnetic disk 305. Further, although not shown, the map information registered by the communication I / F 313 may be transmitted to an external device of the navigation device 300.

  Next, it is determined whether or not a route search request has been received by the input device 310 (step S507). The route search request may be configured such that, for example, the setting of the destination point is accepted by the input device 310 from the passenger.

  In step S507, when the route search request is not accepted (step S507: No), the process proceeds to step S509 to determine whether or not the vehicle has finished traveling.

  If a route search request is received in step S507 (step S507: Yes), the CPU 301 searches for a route to the destination point (step S508). The route search may be performed with reference to the map information registered in step S506. In other words, the use information reception position may be used as the toll road entrance / exit information to search for an optimum route to the destination point.

  Then, the navigation device 300 determines whether or not the traveling of the vehicle is ended by the various sensors 315 or the like (step S509).

  In step S509, when the travel of the vehicle is completed (step S509: Yes), the series of processes is ended as it is. In step S509, if the vehicle does not finish running (step S509: No), the process returns to step S502 and the process is repeated.

  As described above, the navigation device 300 according to the first embodiment registers the toll road entrance / exit information when the position at which the various information is received from the ETC system is not registered in the map information as the toll road entrance / exit. can do. Therefore, even if the smart IC has no entry / exit information registered in the map information, it is possible to perform an appropriate route search and fee guidance using the newly registered map information.

  Furthermore, since map information can be updated to an external device and shared by a plurality of users, an appropriate route search can be performed even when a smart IC has never been used. Furthermore, smart ICs can be effectively used by appropriately setting smart ICs on the route in addition to the local residents and the users who frequently use the surrounding areas where smart ICs are installed.

  In addition, when map matching processing between general roads and toll roads is performed according to the position where various information is received from the ETC system, the map matching performance is improved by using newly registered map information. Can do.

  Next, a second embodiment of the present invention will be described. In the second embodiment, when the map information described in the first embodiment is registered, road data between the toll road and the general road is generated and registered in association with the entrance / exit information of the toll road. To do. The hardware configuration of the navigation apparatus according to the second embodiment is substantially the same as that shown in FIG. 3 and the outline of the smart IC is the same as that shown in FIG.

(Contents of processing of navigation device 300)
Here, the content of the process of the navigation apparatus 300 according to the second embodiment will be described with reference to FIG. FIG. 6 is a flowchart of the process performed by the navigation device according to the second embodiment. In the flowchart of FIG. 6, first, the navigation apparatus 300 determines whether or not the vehicle is traveling (step S601). For example, a configuration in which various types of sensors 315 are used to determine the vehicle traveling may be used.

  In step S601, waiting for the vehicle to travel and when traveling (step S601: Yes), the CPU 301 then performs magnetic disk drive 304 based on the output of the GPS unit 314 and various sensors 315. And the travel locus of the current position of the vehicle moved to the magnetic disk 305 is stored (step S602).

  Although the travel locus is stored in the magnetic disk 305, it may be stored in the optical disk 307 or other memory (not shown). In addition, the travel locus may be stored by repeatedly overwriting a predetermined capacity, as long as the capacity is sufficient for generating road data described later.

  Next, the communication I / F 313 determines whether toll road usage information has been received from an ETC roadside device (step S603). The toll road usage information is information on toll road usage including, for example, a toll road travel section and usage fee.

  In step S603, when toll road usage information is not received from an ETC roadside device (step S603: No), the process proceeds to step S609, and it is determined whether a request for a route search is accepted by the input device 310 (step S603). S609).

  In step S603, when toll road usage information is received from an ETC roadside device (step S603: Yes), the CPU 301 subsequently obtains toll road usage information based on the output information of the GPS unit 314 and various sensors 315. The received usage information reception position is detected (step S604).

  Subsequently, the CPU 301 controls the magnetic disk drive 304 to read map information recorded on the magnetic disk 305 (step S605). In the description of FIG. 6, the map information is recorded on the magnetic disk 305. However, the map information may be recorded on a recording medium such as the optical disk 307 or other memory or an external device. In addition, when it records on the exterior of the navigation apparatus 300, map information is acquired via a network via communication I / F313.

  Then, it is determined whether or not the usage information reception position detected by the CPU 301 in step S604 has been registered as entrance / exit information of the toll road (step S606). Specifically, for example, it is determined whether there is an entrance / exit of a toll road registered in the map information around the usage information reception position.

  In step S606, when it is already registered as the entrance / exit information (step S606: Yes), the process proceeds to step S609, and it is determined whether a request for a route search is received by the input device 310 (step S609).

  In step S606, when it is not registered as the entrance / exit information (step S606: No), road data is generated based on the travel locus stored in step S602 by the CPU 301 (step S607).

  Specifically, for example, road data for connecting a toll road and a general road is generated from a travel locus before and after the vehicle passes through the entrance with the use information reception position as the entrance and exit of the toll road. For example, in the case of a smart IC installed in an SA or PA, the road data may be generated in association with the name of the SA or PA.

  Furthermore, the CPU 301 registers the usage information reception position in the map information in association with the entrance / exit information of the toll road and the road data generated in step S607 (step S608). The entrance / exit information relates to, for example, the location information of the entrance / exit of the toll road at the use information reception location detected in step S604 and the use fee associated with the use section when using the toll road entrance / received received in step S603. Information including information.

  Further, the registration to the map information may be, for example, by editing the map information recorded on the magnetic disk 305 by controlling the magnetic disk drive 304. More specifically, the use information reception position is registered in the road data generated in step S607 in association with map information as entrance / exit information of the toll road. Information to be registered may be registered in a recording medium such as a memory (not shown) different from the magnetic disk 305. Further, although not shown, the map information to be registered may be transmitted to the external device of the navigation device 300 by the communication I / F 313.

  Next, it is determined whether or not a route search request has been received by the input device 310 (step S609). The route search request may be configured such that, for example, the setting of the destination point is accepted by the input device 310 from the passenger.

  In step S609, when the route search request is not accepted (step S609: No), the process proceeds to step S611 to determine whether or not the vehicle has finished traveling (step S611).

  If a route search request is received in step S609 (step S609: Yes), the CPU 301 searches for a route to the destination point (step S610). The route search may be performed with reference to the map information registered in step S608. In other words, the use information reception position may be used as the toll road entrance / exit information to search for an optimum route to the destination point.

  Then, the navigation device 300 determines whether or not the vehicle has been traveled by the various sensors 315 or the like (step S611).

  In step S611, when the vehicle has finished traveling (step S611: Yes), the series of processes is ended as it is. In step S611, if the vehicle does not finish traveling (step S611: No), the process returns to step S602 and the process is repeated.

  As described above, the navigation device 300 according to the second embodiment, when the position where various information is received from the ETC system is not registered as the entrance / exit of the toll road in the map information, It is possible to register road data connecting toll roads and general roads. Therefore, even if the smart IC has no entry / exit information registered in the map information, accurate route guidance can be performed by presenting the generated road data.

  Further, in the navigation device according to the first embodiment or the second embodiment described above, the convenience of the navigation device can be improved by registering the information related to the ETC time zone discount as the entrance / exit information.

  In addition, when there is a time limit in the smart IC, information on the usable time of the smart IC (for example, available from 8:00 to 22:00) is acquired and registered together with the entrance / exit information, and the usable time is set. By performing a route search in consideration, a more appropriate route can be searched.

  In addition, if information related to the installation period of the smart IC is acquired, the newly registered entrance / exit information is deleted at the end of the installation period, so that the data capacity can be effectively used and an incorrect route after the installation period ends. Search can be prevented.

  Moreover, according to this invention, the entrance / exit information of the toll road which is not registered into map information can be newly registered, and can be utilized for route search. Accordingly, it is possible to effectively use a smart IC or the like that is not registered in the map information and perform an appropriate route search. In addition, since it is not necessary for the passenger to memorize the use of the smart IC, the burden on the passenger can be reduced.

  In addition, even if it is an entrance / exit of a toll road that is not registered in the map information, the vehicle position can be corrected using the newly registered entrance / exit information. Therefore, it is possible to improve the accuracy of the vehicle position correction between the general road and the toll road.

  In addition, when the position where various information is received from the ETC system is not registered as the entrance / exit of the toll road in the map information, the entrance / exit information of the toll road can be registered. Therefore, even if the smart IC has no entry / exit information registered in the map information, it is possible to perform an appropriate route search and fee guidance using the newly registered map information.

  Furthermore, since map information can be updated to an external device and shared by a plurality of users, an appropriate route search can be performed even when a smart IC has never been used. Furthermore, smart ICs can be effectively used by appropriately setting smart ICs on the route in addition to the local residents and the users who frequently use the surrounding areas where smart ICs are installed.

  In addition, when performing map matching processing between general roads and toll roads according to the location where various information is received from the ETC system, the newly registered map information is also used to improve map matching performance. be able to.

  The information registration method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
