Description

  The present invention relates to a card insertion warning system and method, a navigation device, and an in-vehicle device, and particularly suitable for use in a system having a function of performing wireless communication with a roadside device using a card inserted into the in-vehicle device. It is a thing.

  One of communication methods for performing wireless communication between a roadside device (wireless device installed on the road side) and an in-vehicle device (wireless device mounted on a vehicle) is called DSRC (Dedicated Short Range Communication). is there. This is a narrow area wireless communication system that has been standardized for ITS (Intelligent Transport Systems). Currently, ETC (non-stop automatic fee payment system) has already been put into practical use, and various services are expected to be realized in the future. For example, as a service in which a vehicle and surrounding facilities cooperate, an automatic fee payment service in a parking lot, a gas station, a fast food drive-through, or the like is considered.

  The Ministry of Land, Infrastructure, Transport and Tourism assumes that in-vehicle devices necessary for applications such as ETC and AHS (driving support road system) will be integrated into one in the future from the viewpoint of promoting the spread of ETC. If an in-vehicle device having an inexpensive and integrated function is realized, the spread of ETC will further advance. However, even if the in-vehicle devices necessary for a plurality of applications are integrated into one, it is expected that the cards necessary for the settlement of fee payments will be prepared separately for each application.

In other words, it is expected that cards used for DSRC in each application such as ETC, parking lot, gas station, and drive-through will be issued individually by each operator. Therefore, for example, although a multi-purpose card that can be used for authentication and settlement on one medium has been devised (see, for example, Patent Document 1), functions necessary for settlement of each application are completely integrated into one card. It is hard to think.

  The present invention has been made to solve such a problem. For each use scene of a DSRC application, the user determines whether a correct type card suitable for the application is inserted in the in-vehicle device. The purpose is to enable easy judgment.

  In order to solve the above-described problems, in the present invention, card type information indicating the type of card used for settlement is inserted into the vehicle-mounted device, and the card type information read from the facility information storage unit storing for each facility. The card type information acquired from the card is compared, and a warning is notified when it is determined that the card type information of both does not match.

  According to the present invention configured as described above, when a service using wireless communication is to be used in a facility such as an ETC, a parking lot, or a drive-through, for example, a card that can be used for the service of the facility is an in-vehicle device. If the card type is not inserted into the card, a warning such as card exchange is issued as a result of determining that the card types do not match. This makes it easy for the user to determine whether the correct type of card suitable for the service is inserted in the in-vehicle device for each use of the wireless communication service at each facility.

The CPU 25 (hereinafter simply referred to as “route search unit”) functioning as a route search unit of the present invention searches for and sets a guide route from the current location to the destination. That is, the route search unit searches for and sets a guide route with the lowest cost among the routes from the current location to the destination using the map data stored in the map information memory 23.

  A CPU 25 (hereinafter simply referred to as “facility presence / absence determination unit”) functioning as a facility presence / absence determination unit of the present invention determines whether or not a DSRC facility exists on the guidance route set by the route search unit. Specifically, the facility presence / absence determination unit refers to the location information of the facility data and the card type information stored in the map information memory 23, and the location information value is on the guidance route set by the route search unit. And the facility ID in which at least one card type information is set is extracted. Then, the facility presence / absence determination unit determines that a DSRC facility exists on the guidance route set by the route search unit when one or more facility IDs are extracted, and sets the route search unit when the facility ID is not extracted. It is determined that there is no DSRC facility on the guidance route.

  The facility presence / absence determination unit may determine whether or not a DSRC facility exists within a certain distance in the traveling direction of the vehicle. Specifically, the facility presence / absence determination unit first refers to the map data stored in the map information memory 23 and the vehicle current position and vehicle orientation data measured by the position measurement unit 22 to determine the vehicle progress. Specify a range that is within a certain distance in the direction. Next, the facility presence / absence determination unit refers to the location information and card type information of the facility data stored in the map information memory 23, and the current position and vehicle direction of the vehicle in which the value of the location information is measured by the location measurement unit 22 The facility ID that is within the range specified with reference to the data and in which at least one card type information is set is extracted.

It is determined whether the card type information acquired by the reader / writer 61 of the device 50 matches.

  Specifically, when the facility presence / absence determining unit extracts one DSRC facility on the guidance route and determines that the DSRC facility exists on the guidance route, the card type determining unit extracts the card type determination unit by the facility presence / absence determining unit. It is determined whether or not the card type information associated with the facility ID of the DSRC facility and the card type information acquired by the reader / writer 61 of the DSRC in-vehicle device 50 match. Similarly, when the facility presence / absence determining unit extracts one DSRC facility within a certain distance in the traveling direction of the vehicle and determines that there is a DSRC facility on the guidance route, the card type determining unit similarly detects both card type information. It is determined whether or not.

  On the other hand, if the facility presence / absence determining unit extracts two or more DSRC facilities on the guidance route and determines that there is a DSRC facility on the guidance route, the card type determination unit determines whether the two or more extracted DSRC facilities are present. Of these, the card type information associated with the facility ID of the nearest DSRC facility and the reader / writer 61 of the DSRC in-vehicle device 50 are acquired so that the nearest DSRC facility from the vehicle position is a warning notification target. It is determined whether or not the card type information matches. Similarly, when the facility presence / absence determining unit extracts two or more DSRC facilities within a certain distance in the traveling direction of the vehicle and determines that there is a DSRC facility on the guidance route, the card type determining unit is also the closest DSRC. It is determined whether the card type information associated with the facility ID of the facility matches the card type information acquired by the reader / writer 61.

  When a plurality of pieces of card type information are associated with a single facility ID, the card type determination unit determines whether any of the plurality of pieces of card type information associated with the one facility ID is a reader / writer. It is determined whether or not the card type information acquired in 61 matches.

When the card type determination unit determines that the card type information acquired by the writer 61 does not match, the warning is displayed on the display device 40 via the image composition unit 37. Further, the notification unit may notify the warning by voice via the speaker 41 instead of or in addition to displaying the warning on the display device 40.

  Next, the operation of the card insertion warning system configured as described above will be described. 4 to 6 are flowcharts showing an example of the operation of the card insertion warning system shown in FIG. FIG. 7 is a diagram schematically showing card type information and the like temporarily stored in the RAM 28. 4 and 5, the left side shows the operation of the DSRC in-vehicle device 50, and the right side shows the operation of the navigation device 12. FIG. 6 shows in detail the operation of the notification process shown in FIGS. In this flowchart, when the DSRC in-vehicle device 50 receives an input to start an operation through an operation unit (not shown), the navigation device 12 receives an input to start an operation through the operation unit 30. In each case, each operation shall be started.

  4, the mounting determination unit 62 of the DSRC in-vehicle device 50 determines whether the DSRC card 100 has been inserted into the card insertion slot or whether the DSRC card 100 that has been inserted into the card insertion slot has been removed (step). S100). When the attachment determination unit 62 determines that the DSRC card 100 has been inserted into the card insertion slot (step S100: Yes), the communication interface unit 60 of the DSRC in-vehicle device 50 inserts the card into the communication interface unit 20 of the navigation device 12. The card type information of the DSRC card 100 inserted into the mouth is transmitted (step S102).

  When the attachment determination unit 62 determines that the DSRC card 100 that has been inserted into the card insertion slot has been removed (step S100: Yes), the communication interface unit 60 of the DSRC in-vehicle device 50 performs communication with the navigation device 12. Information indicating that the DSRC card 100 inserted in the card insertion slot has been removed is transmitted to the interface unit 20 (step S102). On the other hand, when the attachment determination unit 62 determines that the DSRC card 100 is inserted into the card insertion slot and the DSRC card 100 that has been inserted into the card insertion slot is not removed (step S100: No), Proceed to step S150 in FIG.

  In FIG. 4, the CPU 25 of the navigation device 12 determines whether or not the card type information or the information indicating that the DSRC card 100 inserted into the card insertion slot has been extracted from the DSRC in-vehicle device 50. (Step S204). When the CPU 25 determines that the card type information has been received from the DSRC in-vehicle device 50 (step S204: Yes), the CPU 25 temporarily stores the received card type information in the storage area 281 on the RAM 28 shown in FIG. Store (step S206). If the previously received card type information is temporarily stored in the storage area 281 on the RAM 28, the CPU 25 overwrites it with the card type information received this time.

  Further, when the CPU 25 determines that the information indicating that the DSRC card 100 inserted into the card insertion slot has been removed from the DSRC in-vehicle device 50 (step S204: Yes), the CPU 25 stores the information on the RAM 28. The card type information stored in the storage area 281 is deleted (the storage area 281 is initialized) (step S206). On the other hand, if the CPU 25 determines that the card type information and the information indicating that the DSRC card 100 inserted into the card insertion slot has been removed from the DSRC in-vehicle device 50 (step S204). : No), the process proceeds to step S210.

  Subsequent to step S204 or step S206, the route search unit determines whether the guidance route is set or reset by reroute (step S210). When the route search unit determines that the guide route is set or reset (step S210: Yes), the facility presence / absence determination unit determines whether a DSRC facility exists on the guide route (step S212). . When the facility presence / absence determination unit determines that a DSRC facility exists on the guidance route (step S212: Yes), the facility presence / absence determination unit determines the available card type information and settlement for each DSRC facility present on the guidance route. The condition information is temporarily stored in the storage area 282 on the RAM 28 whose data structure is shown in FIG. 7B (step S214).

  If the facility presence / absence determination unit temporarily stores in the storage area 282 the card type information and settlement condition information for each DSRC facility on the guidance route previously set or reset by the route search unit, It is overwritten by card type information and settlement condition information for each DSRC facility on the guidance route set or reset by the route search unit. Further, the facility presence / absence determination unit preferably temporarily stores the card type information and the settlement condition information in the storage area 282 on the RAM 28 in the order of arrival (route order) of each DSRC facility existing on the guidance route. That is, the facility presence / absence determination unit temporarily stores the card type information and the settlement condition information of the first arriving DSRC facility in association with the DSRC facility 1 in the storage area 282, and the card type information of the second arriving DSRC facility and The payment condition information is temporarily stored in association with the DSRC facility 2 in the storage area 282 (the same applies to the third and subsequent items).

  Subsequent to step S214, the facility presence / absence determination unit measures the own vehicle measured by the position measurement unit 22 among the card type information and settlement condition information of the DSRC facility on the guidance route temporarily stored in the storage area 282 in step S214. The card type information and settlement condition information of the DSRC facility on the guide route closest to the current location of the current location are temporarily stored in the storage area 283 on the RAM 28 whose data structure is shown in FIG. 7C (step S216). Here, the facility presence / absence determination unit temporarily stores the card type information and the settlement condition information in the storage area 282 on the RAM 28 in the order of arrival of each DSRC facility on the guidance route. Information and settlement condition information may be temporarily stored in the storage area 283 on the RAM 28.

  The facility presence / absence determining unit overwrites the card type information and the payment condition information with the card type information and the payment condition information when the card type information and the payment condition information are already temporarily stored in the storage area 283, as in the storage area 282. Then, the card type determination unit and the notification unit store the card type information temporarily stored in the storage area 281 on the RAM 28 in step S206, and the card type information and payment temporarily stored in the storage area 283 on the RAM 28 in step S216. A notification process is executed using the condition information (step S300).

  On the other hand, when the route search unit determines that the guide route is not set or reset (step S210: No), or when the facility presence determination unit determines that there is no DSRC facility on the guide route (Step S212: No), it progresses to Step S220 of FIG.

  In FIG. 5, following step S210, step S212, or step S300, the CPU 25 of the navigation device 12 determines whether or not a guidance route is set in the guidance route memory 29 (step S220). When the CPU 25 determines that the guidance route is set in the guidance route memory 29 (step S220: Yes), the CPU 25 performs DSRC on the guidance route closest to the current position of the host vehicle measured by the position measurement unit 22. It is determined whether or not the facility approaches within a predetermined distance from the own vehicle (step S222).

  When the CPU 25 determines that the DSRC facility on the guide route closest to the current position of the host vehicle has approached within a predetermined distance from the host vehicle (step S222: Yes), the card type determination unit and the notification unit perform steps S206. The notification process is executed using the card type information temporarily stored in the storage area 281 on the RAM 28 and the card type information and settlement condition information temporarily stored in the storage area 283 on the RAM 28 in step S216 or S236. (Step S302). On the other hand, if the CPU 25 determines that the DSRC facility on the guide route closest to the current position of the host vehicle is not approaching within a predetermined distance from the host vehicle (step S222: No), the process proceeds to step 230.

  Subsequent to step S222 or step S302, the CPU 25 of the navigation device 12 determines whether or not the vehicle has passed the nearest DSRC facility on the guidance route based on the current position of the host vehicle measured by the position measurement unit 22. (Step S230). If the CPU 25 determines that it has passed the nearest DSRC facility on the guidance route (step S230: Yes), the facility presence / absence determination unit stores the card of the DSRC facility on the guidance route temporarily stored in the storage area 282 in step S214. Among the type information and the payment condition information, the card type information and the payment condition information of the DSRC facility on the guide route closest to the current position of the vehicle measured by the position measurement unit 22 are again stored in the storage area 283 on the RAM 28. Temporary storage is performed (step S236). Here, when the facility presence / absence determination unit temporarily stores the card type information and the settlement condition information in the storage area 282 on the RAM 28 in the order of arrival of each DSRC facility on the guidance route, The card type information and settlement condition information of the DSRC facilities in the order of arrival may be temporarily stored in the storage area 283 on the RAM 28.

  That is, in step S 236, the card type information and the payment conditions of the nearest DSRC facility on the guidance route that has not passed are temporarily stored in the storage area 283 on the RAM 28. Accordingly, it is possible to sequentially determine whether or not the correct type of DSRC card 100 suitable for the service is inserted in the DSRC in-vehicle device 50 in the order of the DSRC facilities expected to arrive, and notify a warning if necessary. . On the other hand, if the CPU 25 determines that it has not passed through the nearest DSRC facility on the guidance route (step S230: No), the process proceeds to step S250.

  On the other hand, when the CPU 25 determines that the guidance route is not set in the guidance route memory 29 (step S220: No), the facility presence / absence determination unit determines whether the DSRC facility exists within a certain distance in the traveling direction of the vehicle. Is determined (step S240). When the facility presence / absence determination unit determines that a DSRC facility exists within a certain distance in the traveling direction of the vehicle (step S240: Yes), the facility presence / absence determination unit determines the most from the current position of the host vehicle measured by the position measurement unit 22. The card type information and settlement condition information of the DSRC facility within a short distance in the direction of travel are temporarily stored in the storage area 283 on the RAM 28 (step S246).

  Then, the card type determination unit and the notification unit store the card type information temporarily stored in the storage area 281 on the RAM 28 in step S206, and the card type information and settlement temporarily stored in the storage area 283 on the RAM 28 in step S246. A notification process is executed using the condition information (step S304). On the other hand, if the facility presence determination unit determines that there is no DSRC facility within a certain distance in the traveling direction of the vehicle (step S240: No), the process proceeds to step S250.

  Following step S100 or step S102, the signal processing unit 65 of the DSRC in-vehicle device 50 determines whether or not it has received an input to end the operation of the card insertion warning system via the operation unit (not shown) of the DSRC in-vehicle device 50. Judgment is made (step S150). If the signal processing unit 65 of the DSRC in-vehicle device 50 determines that the input to end the operation has not been received (step S150: No), the process returns to step S100 in FIG. Similarly, following step S230, step S236, step S240, or step S304, the CPU 25 of the navigation device 12 determines whether or not an input to end the operation of the card insertion warning system is received via the operation unit 30. (Step S250). If the CPU 25 of the navigation device 12 determines that the input to end the operation has not been received (step S250: No), the process returns to step S204 in FIG.

  On the other hand, when the signal processing unit 65 of the DSRC in-vehicle device 50 determines that an input for ending the operation has been received (step S150: Yes), the flowchart of the DSRC in-vehicle device 50 ends. Similarly, when the CPU 25 of the navigation device 12 determines that an input to end the operation has been received (step S250: Yes), the flowchart of the navigation device 12 ends.

  Next, the notification process by the card type determination unit and the notification unit of the navigation device 12 will be described. In FIG. 6, the card type determination unit temporarily stores the card type information received from the DSRC in-vehicle device 50, that is, the card type information of the DSRC card 100 inserted into the DSRC in-vehicle device 50 in the storage area 281 on the RAM 28. It is determined whether or not (step S310). When the card type determination unit determines that the card type information of the DSRC card 100 inserted into the DSRC in-vehicle device 50 is not temporarily stored in the storage area 281 on the RAM 28 (step S310: No), the notification unit A warning that the DSRC card 100 has not been inserted is notified (step S320). And this flowchart is complete | finished.

  On the other hand, when the card type determination unit determines that the card type information of the DSRC card 100 inserted into the DSRC in-vehicle device 50 is temporarily stored in the storage area 281 on the RAM 28 (step S310: Yes), the card The type determination unit is one card type information read from the map information memory 23, that is, the card type information of the DSRC facility closest to the current position of the own vehicle, and the card acquired by the reader / writer 61 of the DSRC in-vehicle device 50. It is determined whether or not the type information matches (step S312). Specifically, the card type determination unit determines whether or not the card type information temporarily stored in the storage area 283 on the RAM 28 matches the card type information temporarily stored in the storage area 281 on the RAM 28. Determine. Here, when a plurality of pieces of card type information are temporarily stored in the storage area 283 on the RAM 28, the card type determination unit and any one of the card type information and the card temporarily stored in the storage area 281 on the RAM 28. It is determined whether or not the type information matches.

  When the card type determination unit determines that the one card type information read from the map information memory 23 and the card type information acquired by the reader / writer 61 of the DSRC in-vehicle device 50 do not match (step S312). : No), the notification unit notifies the warning that the DSRC card 100 inserted in the DSRC in-vehicle device 50 is not usable in the DSRC facility (step S322). That is, a warning that the service cannot be used due to a wrong card insertion is notified. And this flowchart is complete | finished.

  On the other hand, when the card type determination unit determines that one card type information read from the map information memory 23 matches the card type information acquired by the reader / writer 61 of the DSRC in-vehicle device 50 ( In step S312: Yes, the card type determination unit determines whether or not the payment condition information of the DSRC card 100 in the DSRC facility indicates “priority” (step S314). Specifically, the card type determination unit associates the card condition information temporarily stored in the storage area 281 on the RAM 28 with the payment condition information temporarily stored in the storage area 283 on the RAM 28 as “priority”. It is determined whether or not it indicates that there is.

  When the card type determination unit determines that the payment condition information of the DSRC card 100 in the DSRC facility does not indicate “priority” (step S314: No), the notification unit gives priority to the DSRC card 100. A warning that it is not a card is issued (step S324). And this flowchart is complete | finished. On the other hand, when the card type determination unit determines that the payment condition information of the DSRC card 100 in the DSRC facility indicates “priority” (step S314: Yes), the flowchart ends.

  Note that the warning notification in steps S320, S322, and S324 may be one of message output to the display device 40 and voice output to the speaker 41, or both. Further, in step S320, the notifying unit detects the DSRC card 100 based on the type of the DSRC card 100 to be inserted or the type of the DSRC card 100 to be inserted in addition to the warning that the DSRC card 100 is not inserted. Information shown to the user (for example, the name of the DSRC card 100) may be displayed. The same applies to the warnings in step S322 and step S324.

  FIG. 8 is a diagram showing another configuration example relating to the card insertion warning system of the present embodiment. As shown in FIG. 8, the card insertion warning system includes a navigation device 10 and a DSRC in-vehicle device 52 that are communicably connected to each other. Since the same reference numerals as those shown in FIG. 1 indicate the same functions, the description thereof is omitted.

  In the card insertion warning system shown in FIG. 1 described above, the CPU 25 of the navigation device 12 functions as the card type determination unit and the notification unit of the present invention. However, in the card insertion warning system shown in FIG. The signal processing unit 69 functions as a card type determination unit and a notification unit. In the card insertion warning system shown in FIG. 1, the navigation device 12 includes the speaker 41. However, in the card insertion warning system shown in FIG. 8, the DSRC in-vehicle device 52 includes the speaker 71. The display device 70 of the DSRC in-vehicle device 52 may be a lamp such as an LED.

  In the card insertion warning system shown in FIG. 8, the communication interface unit 20 of the navigation device 10 sends one card type information read from the map information memory 23 to the communication interface unit 60 of the DSRC in-vehicle device 52, that is, the own vehicle. The card type information and settlement condition information of the DSRC facility closest to the current location of the current location is transmitted.

  The card type determination unit of the DSRC in-vehicle device 52 matches the card type information read from the map information memory 23 of the navigation device 10 with the card type information acquired by the reader / writer 61 of the DSRC in-vehicle device 52. Judge whether or not. In addition, when the card type determination unit of the DSRC in-vehicle device 52 determines that the card type information of both is the same, the payment condition information read from the map information memory 23 of the navigation device 10 is further added. , It is determined whether or not the payment condition information of the DSRC card 100 in the DSRC facility indicates “priority”.

  If the notifying unit of the DSRC on-vehicle device 52 does not match the card type information read from the map information memory 23 of the navigation device 10 and the card type information acquired by the reader / writer 61 of the DSRC on-vehicle device 52, the DSRC. When it is determined by the card type determination unit of the in-vehicle device 52, a warning is displayed on the display device 70 for notification. Further, the notification unit of the DSRC in-vehicle device 52 may notify the warning by voice through the speaker 71 instead of or in addition to displaying the warning on the display device 70.

  As described above, according to the present embodiment, when the guidance route is set or reset, and the DSRC facility exists on the guidance route, the card type determination unit and the notification unit execute the notification process ( Step S300 in FIG. As a result, it is determined whether the correct type of DSRC card 100 suitable for the service is inserted in the DSRC in-vehicle device 50 at the timing when the guidance route is set before traveling and when the reroute occurs during traveling. It is possible to make the user avoid as much as possible the state in which the service cannot be used due to a wrong insertion of the DSRC card 100 at a timing when there is a relatively long time before approaching the DSRC facility where there is a possibility of stopping.

  In addition, according to the present embodiment, when the vehicle is traveling with a guidance route set, the DSRC facility on the guidance route closest to the current position of the vehicle approaches within a predetermined distance from the vehicle. In addition, the card type determination unit and the notification unit perform notification processing (step S302 in FIG. 5). As a result, it is determined whether the correct type of the DSRC card 100 suitable for the service is inserted in the DSRC in-vehicle device 50 at the timing when the DSRC facility that may possibly stop is actually approached. Even when the DSRC card 100 is replaced, it is possible to make the user avoid as much as possible the state in which the service cannot be used due to an erroneous insertion of the DSRC card 100.

  Further, according to the present embodiment, when the guidance route is not set and the DSRC facility exists within a certain distance in the traveling direction of the vehicle, the card type determination unit and the notification unit execute the notification process. (Step S304 in FIG. 5). As a result, even if the guidance route is not set, is the correct type of DSRC card 100 suitable for the service inserted in the DSRC in-vehicle device 50 at the timing of approaching the DSRC facility within a certain distance in the traveling direction of the vehicle? Therefore, it is possible to further avoid a situation in which the service cannot be used due to a wrong card insertion.

  In addition to the above timing, the card type determination unit and the notification unit may execute the notification process at a timing when the card type information is received from the DSRC in-vehicle device 50 (step S204: Yes in FIG. 4). As a result, at the timing when the DSRC card 100 is inserted into the DSRC in-vehicle device 50 (including replacement), it is determined whether the correct type of the DSRC card 100 suitable for the service is inserted into the DSRC in-vehicle device 50. It is possible to further avoid a situation in which the service cannot be used due to an incorrect insertion of.

  In this embodiment, the card type determination unit and the notification unit indicate that the DSRC facility is located when the nearest DSRC facility on the guidance route approaches within a predetermined distance from the own vehicle or within a certain distance in the traveling direction of the vehicle. When it exists, the notification process is executed (steps S302 and S304), but the notification process may be executed based on other conditions. For example, the card type determination unit and the notification unit are vehicle speed information detected by the vehicle speed sensor of the position measurement unit 22 when the nearest DSRC facility on the guidance route approaches within a predetermined distance from the host vehicle. When the CPU 25 determines that the vehicle speed is equal to or lower than a predetermined speed based on the above, the notification process may be executed. Thus, for example, when there is a high possibility of stopping at the DSRC facility during traveling, for example, when accompanied by a slow motion in front of the DSRC facility, the correct type of DSRC card 100 suitable for the service is installed in the DSRC in-vehicle device. Therefore, it is possible to issue a warning at a timing useful to the user.

  Further, the card insertion warning system according to the present embodiment may operate so as to execute the notification process based on information related to driving of the vehicle in addition to the information acquired from the position measurement unit 22. Hereinafter, a card insertion warning system that operates based on information related to driving of the vehicle will be described.

  In the internal configuration of the drive control unit 80, reference numeral 92 denotes a steering information acquisition unit that acquires steering drive information, and 96 denotes a communication interface unit. In the card insertion warning system shown in FIG. 9, the card type determination unit and the notification unit, for example, notify the CPU 25 when the DSRC facility on the guide route closest to the current position of the vehicle approaches within a predetermined distance from the vehicle. And the CPU 25 determines that the vehicle speed is equal to or lower than a predetermined speed based on the vehicle speed information detected by the vehicle speed sensor of the position measurement unit 22 and is acquired by the steering information acquisition unit 92. When the CPU 25 determines that the operation angle of the steering wheel is greater than or equal to a predetermined value based on the steering information, the notification process may be executed. As a result, the correct type of card suitable for the service can be used only when there is a high possibility of stopping at the DSRC facility during traveling, such as when the vehicle is slowly driven in front of the DSRC facility and the steering wheel is turned. Therefore, it is possible to issue a warning at a timing useful to the user.

  In addition, instead of or in addition to the steering information acquisition unit 92, the drive control unit 80 includes respective acquisition units that acquire information on other operations of the vehicle, such as a winker information acquisition unit that acquires display control information of the winker. You may have. And based on these operation | movement information, it may be judged whether predetermined conditions are satisfy | filled, and you may perform alerting | reporting processing, when satisfy | filling. As a result, only when there is a higher possibility of stopping at the DSRC facility while driving, it is determined whether or not the correct type of card suitable for the service is inserted in the vehicle-mounted device. Can be issued.

  It should be noted that when the guidance route is set or reset and there is a DSRC facility on the guidance route, when the vehicle is traveling with the guidance route set, the closest guidance from the current position of the vehicle One of the cases where the DSRC facility on the route approaches within a predetermined distance from the own vehicle, or when the guidance route is not set and the DSRC facility exists within a certain distance in the traveling direction of the vehicle. In this case, or in two cases, the card type determination unit and the notification unit may execute a notification process.
