Description

  For example, the present invention relates to a vehicle-mounted device used in an ETC system (Electronic Toll Collection system), and more particularly to a vehicle-mounted device that can support a plurality of applications including an ETC function.

  2. Description of the Related Art Conventionally, ETC systems in Japan are based on IC cards (so-called ETC cards) that store ETC on-board devices that collect tolls by way of two-way wireless communication with on-road devices installed on the road, and information on fee settlement for settlement. ) And.

  In the ETC system, an IC card on which information necessary for ETC payment is recorded is inserted into an on-vehicle device in which vehicle information is registered in advance, and the vehicle is inserted into an exit toll gate or entrance toll gate on a toll road. When this occurs, the roadside equipment installed at the toll booth reads out the information on the vehicle-mounted device and the IC card through a wireless antenna by wireless communication, and automatically settles the toll for the vehicle.

  On the other hand, as for a so-called credit card having a payment function other than ETC, an IC card equipped with an IC chip is becoming popular instead of a conventional magnetic card. An IC card with a built-in credit settlement function is installed in an in-vehicle device that supports credit settlement, and the in-vehicle device uses the wireless communication with the outside to perform authentication and settlement processing with the IC card. Credit settlement services have also started.

  There is also a vehicle-mounted device that can handle a plurality of applications including these ETC functions (for example, see Patent Document 1). In such an in-vehicle device, when the user uses the ETC system, an IC card having an ETC function is inserted, and in other than the ETC, for example, in the parking lot settlement, an IC card having a credit settlement function is inserted in the on-vehicle device. As such, it can be used properly by the user's replacement operation.

  However, since such a replacement operation is necessary, for example, it is assumed that the user notices immediately before the ETC gate and inserts an IC card having an ETC function. In this case, the driving operation is hindered, and there is a concern that the billing process cannot be normally performed if the ETC gate is entered before the authentication with the IC card is completed. In reality, it takes about several seconds to 10 seconds from the time when the IC card is inserted until the ETC payment process can be executed.

  Therefore, as disclosed in Patent Document 2, for example, a so-called multi-function IC that incorporates both an ETC payment function and, for example, the credit payment function other than the ETC so that the IC card does not have to be replaced. Cards are also being considered. With the spread of multifunction IC cards, it is expected that the number of cards held by the user will be reduced and the number of cards issued by the card company will be reduced.

As can be seen from the description in FIGS. 3 and 4 and paragraph 0025 of Patent Document 2, in the invention disclosed in Patent Document 2, no matter what application program is executed, the in-vehicle device is always surely finally. The multi-function IC card is discharged from the vehicle-mounted device after the top-priority execution application program defined by the execution priority information stored in is executed. As a result, even when the IC card is used next time, the application program for ETC set on the vehicle-mounted device side can be started in a short time.
Japanese Patent Laid-Open No. 2004-62468 JP 2006-119946 A

  However, in the invention disclosed in Patent Literature 2, the ETC system application program is executed before the multifunction IC card is ejected from the vehicle-mounted device, and then the program is terminated, and the next time the multifunction IC card is used. This is only a convenience.

  For this reason, it is not possible to deal with a case in which a multi-function IC card is mounted on the vehicle-mounted device and credit settlement is performed at a parking lot and then settlement is performed using an ETC service. However, in order to enjoy the advantages of the invention disclosed in Patent Document 2, it is necessary to always discharge the multi-function IC card. That is, the user is forced to insert (mount) the multi-function IC card again, and the above-mentioned merit cannot be enjoyed when the user's insertion operation is delayed.

  The present invention has been made in view of such a problem, and it is possible to prevent the convenience at the time of using a predetermined function from being impaired while a so-called multi-function IC card is still mounted on the vehicle-mounted device. An object is to provide a vehicle-mounted device that can be used.

The vehicle-mounted device of the present invention (1. Similarly, reference numerals of constituent elements in the embodiment are shown in parentheses) are a communication means (11) for communicating with an external device (3), and an IC card. An IC card connector (15) into which (2) can be inserted and removed, an information acquisition means (14) for acquiring information from the IC card (2) inserted into the IC card connector (15), and a communication means (11) And various types of applications corresponding to a plurality of application processes including a predetermined highest priority application process that requires at least an IC card authentication process based on information acquired by the information acquisition means (14). Control means (13) for executing control and storage means (17) for storing information on whether or not access to the IC card has occurred .

The control means (13) performs the following control.
(A) When an IC card is inserted into the IC card connector in the power supply state, when power supply is started with the IC card inserted into the IC card connector, the power supply starts. Sometimes, after activating an IC card, it is determined whether the inserted IC card is compatible with the highest priority application process. If the IC card is compatible with the highest priority application, at least authentication based on the highest priority application process is performed. Execute the process.

  It is conceivable to include a road machine (3) in the external device. Moreover, as the highest priority application process, for example, a payment process (referred to as an ETC payment process) in an ETC system (Electronic Toll Collection system) is cited. Hereinafter, in order to facilitate understanding, an ETC payment process will be described as an example of the highest priority application process. By performing the control shown in (a), since at least the authentication process has been completed, if it becomes necessary to perform the ETC settlement process thereafter, the process can be executed immediately. it can.

( B) Thereafter, when an application process that causes access to the IC card is executed other than the highest priority application process, the fact that the access to the IC card has occurred is stored in the storage means.

(C) When control based on application processing other than the highest priority application processing ends, it is determined whether access to the IC card has occurred in the application processing based on the storage contents of the storage means, and the IC card When access to the device occurs, after the IC card is reactivated, authentication processing based on at least the highest priority application processing is executed.

By performing the control shown in (c) , since at least the authentication process has been completed, if it becomes necessary to perform the ETC settlement process thereafter, the process can be executed immediately. it can.

  Thus, according to the vehicle-mounted device of the present invention, the so-called multi-function IC card remains attached to the vehicle-mounted device, and the convenience during use of the highest priority application processing (for example, ETC payment processing) function is not impaired. Can be.

  By the way, as a user, it is one of the concerns whether the highest priority application process can be executed or not. Therefore, it is preferable to notify them to the user.

  For example, when the control means executes an authentication process based on at least the highest priority application process and is in a state where the highest priority application process can be executed, a notification unit (18, 23 or navigation device) that can notify the user It is conceivable to notify that the highest priority application process can be executed via the display unit 5 or the speaker 5. In addition, when executing the application process other than the highest priority application process, the control unit may notify the user that the highest priority application process is in an inexecutable state via a notification unit that can notify the user. Conceivable.

Further , when executing an application process that causes access to the IC card other than the highest- priority application process, it may be executed after the control unit once deactivates the IC card and activates it again . As shown in (a) above, when the ETC payment process as a specific example of the highest priority application process is immediately executable, the information acquisition means (14) can access information necessary for the ETC payment process. It is in a state. Of course, application processing other than ETC payment processing may be executed in this state, but the information acquisition means (14) can acquire information necessary for ETC payment processing by an instruction from an external device (3) such as a roadside device. Therefore, if no action is taken, it will lead to information leakage. Therefore, in the vehicle-mounted device of the present invention, when executing application processing other than ETC payment processing, the IC card is once deactivated and activated again. This prevents leakage of information necessary for ETC payment processing.

  On the other hand, when executing an application process that does not cause access to the IC card other than the highest-priority application process, the control means may perform the following control. That is, the activated state is maintained without deactivating the IC card.

If access to the IC card does not occur, there is no need to inactivate because there is no fear of leakage of information in the IC card. Therefore, if the activation state is maintained without performing the activation, the authentication process has been performed before that, so there is no need to authenticate again. Therefore, it is effective for shortening the time until the highest priority application process can be executed .

  Then, when it is determined that the control based on the application process other than the highest priority application process is finished and the access to the IC card has not occurred, the activation state of the IC card is continued and the authentication based on the highest priority application process is performed. It can be considered that the processing is maintained, and that it is in a state where the highest-priority application processing can be executed via a notification unit that can notify the user.

  As an example of the highest priority application process, the settlement process in the ETC system can be considered as described above. In the case of ETC payment processing, it is a reality that it takes about several seconds to 10 seconds from when an IC card is inserted into the IC card connector until ETC payment processing can be executed. Therefore, it is effective to make such processing immediately executable.

Of course, in other cases, at least application processing that requires IC card authentication processing may be set as the highest priority application processing.
The control means described above can be realized as a program that causes a computer to function. In the case of such a program, for example, it is recorded on a computer-readable recording medium such as FD, MO, DVD-ROM, CD-ROM, hard disk, etc., and is used by being loaded into a computer and started up as necessary. it can. In addition, the ROM or backup RAM may be recorded as a computer-readable recording medium, and the ROM or backup RAM may be incorporated into the computer for use.

  Embodiments to which the present invention is applied will be described below with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and can take various forms as long as they belong to the technical scope of the present invention.

(About IC card 2)
Next, the IC card 2 will be described.
The IC card 2 exchanges data with the IC card control unit 14 via the IC card connector 15 of the in-vehicle device 1, the storage unit 22 configured by a nonvolatile memory capable of storing and reading information, A control unit 21 that controls the storage unit 22 is provided.

  The storage unit 22 stores programs for a plurality of application processes including an ETC payment process and a parking lot payment process. That is, the IC card 2 has a plurality of functions such as a credit settlement function provided in an IC card called a credit card in addition to an ETC payment function provided in an IC card called a conventional ETC card. Is called a so-called multi-function IC card.

  The storage unit 22 also stores contract information including the expiration date of the contract in the credit, payment information for deducting the toll road usage fee, and the like. The storage unit 22 also stores IC card identification information (card ID) for specifying the IC card 2 in advance.

  For example, when executing the ETC settlement process, the information read from the IC card 2 is transmitted to the road unit 3 as a part of the vehicle-mounted device information when the vehicle passes the toll gate, and is returned as a response. The storage unit 22 stores the toll gate information such as the gate passage time, the gate number for specifying the toll gate, and the use history information such as the vehicle type of the vehicle.

  When the IC card 2 is attached to the vehicle-mounted device 1, information inside the IC card is read into the vehicle-mounted device 1. This information is transmitted as vehicle-mounted device information together with vehicle information registered in the vehicle-mounted device 1 in advance during wireless communication. The vehicle-mounted device 1 performs a wireless communication with the roadside device 3 for toll settlement installed at the entrance or exit of the toll gate on the toll road, and calculates the toll.

In addition, when wireless communication is performed with the road device 3 for card confirmation, the card information is transmitted to the road device 3 for card confirmation.

  In addition, when wireless communication is performed with a credit settlement roadside device 3 installed at an exit of a parking lot or the like, the vehicle-mounted device 1 is necessary for credit settlement from the IC card 2 in accordance with an instruction from the credit settlement roadside device 3. The correct card information. The read card information is transmitted by radio communication to a road device for credit settlement, and credit settlement processing is performed.

[Operation explanation of on-vehicle device 1]
Next, the operation of the vehicle-mounted device 1 of the present embodiment will be described.
2 and 3 are sequence diagrams showing an operation example (with reactivation and re-authentication) when the IC card service is used by wireless communication, and FIG. 4 does not use the IC card service by wireless communication. It is a sequence diagram which shows the operation example (no reactivation and no re-authentication) at the time of being. FIG. 5 is a flowchart showing processing executed in the vehicle-mounted device 1 after performing wireless communication other than the ETC with the roadside device 3. The following will be described in order.

(1) Example of operation when using IC card service by wireless communication When an ignition switch 7 (not shown) is turned on, power supply to each part of the vehicle-mounted device 1 is started (power ON state) (B1).

  When the user inserts the IC card 2 into the IC card connector 15 (D1), the IC card 2 is activated (B2), and card information (here, card type information) is acquired from the IC card 2. The card type is determined (B3). Here, the discussion proceeds on the assumption that the card is a so-called multi-function IC card that includes ETC payment as described above and further supports a plurality of application processes such as parking lot payment.

  Then, the card authentication is performed by exchanging with the IC card 2 (B4), and if the authentication is successful, the access permission setting to the card information with access restriction in the IC card 2 is made (C1). And the vehicle equipment 1 reads card information (for example, payment information etc.) from IC card 2 (B5). Since this process enables ETC settlement, control is performed to notify that ETC is available (B6).

  In accordance with this notification control, ETC availability notification is performed both in display and through the display unit 18 and the speaker 23 of the vehicle-mounted device 1 or the display unit and the speaker in the navigation device 5 (D2). Of course, either one of display and sound may be notified, but in this embodiment, notification is made by both display and sound.

  In the vehicle-mounted device 3 currently used by general users, for example, several seconds to 10 seconds from when the IC card 2 is inserted into the IC card connector 15 until notification that the ETC is available is made. Many of them require a certain amount of time.

  After the ETC settlement becomes possible, when the wireless communication is actually performed with the road device 3 for ETC settlement, a known ETC settlement process is executed. Since the present invention is characterized by coping with application processing other than ETC payment, this ETC payment processing will not be described in detail.

  A case will be described in which wireless communication is started with a road device 3 other than the road device 3 for ETC payment after the ETC payment becomes possible. Whether or not wireless communication has started with a road device 3 that does not use an ETC application, such as a road device 3 for credit settlement, is identified by an application ID (AID) included in the wireless communication from the road device 3. be able to.

  In this case, the vehicle-mounted device 1 first performs control to notify that the use of ETC has become impossible (B7). In accordance with this notification control, an ETC use disapproval notification is given both via display and voice via the display unit 18 and speaker 23 of the vehicle-mounted device 1 or the display unit and speaker of the navigation device 5 (D3).

  Thereafter, for example, when performing a service that does not use the IC card 2 (a case where the vehicle-mounted device 1 and the roadside device 3 perform data communication) (A1), the vehicle-mounted device 1 performs processing corresponding to the service (for example, Data communication) is performed (B8).

  Thereafter, when performing a service using the IC card 2 (for example, credit settlement with a credit settlement road device 3 installed at an exit of a parking lot, etc.), the use of the IC card 2 from the road device 3 is performed. When the start process is performed (A2), the vehicle-mounted device 1 that has received the use start request from the roadside device 3 first deactivates the IC card 2 (B9). As a result, the setting for permitting access to the IC card 2 made by the above-described IC card authentication (B4) is canceled and the setting for prohibiting access to the IC card 2 is made (C2). By this processing, the roadside device 3 cannot access information necessary for ETC payment.

Thus, after deactivating the IC card 2 once, the vehicle-mounted device 1 activates the IC card 2 again (B10).
In this state, when the road device 3 performs a process related to the IC card request service (A3), a request command is transmitted from the road device 3 to the vehicle-mounted device 1, and the vehicle-mounted device 1 that has received the request command corresponds to the request command. Processing is performed (B11). When an IC card command is issued from the vehicle-mounted device 1 to the IC card 2, IC card response data is returned from the IC card 2. The vehicle-mounted device 1 that has received the response data performs processing corresponding to the response data (B12). A response command is transmitted from the vehicle-mounted device 1 to the roadside device 3, and the roadside device 3 that has received the response command performs an IC card response service (A4).

  By such processing, the roadside device 3 can access the IC card 2 via the vehicle-mounted device 1 and can perform credit settlement. On the other hand, the vehicle-mounted device 1 does not have to have a credit settlement process.

Processing after a series of wireless communication between the road unit 3 and the vehicle-mounted device 1 is completed will be described with reference to FIG.
When the wireless communication is completed, the vehicle-mounted device 1 determines use of the IC card 2 (B13). For example, in the IC card deactivation at B9 in FIG. 2, it is conceivable to set a flag indicating “re-authentication required” and perform the use determination at B13 based on the state of the flag. This flag is stored in the storage unit 17.

  In the case shown in FIG. 3, since the IC card 2 is used, the IC card 2 is reactivated (B14), and the IC card 2 is re-authenticated (B15). This re-authentication process requires the same process as when the IC card 2 is inserted. For example, the type of the IC card 2 may be determined based on the already determined ETC payment function. By using the payment information read at the time of insertion as it is, it is possible to shorten the time until the ETC becomes available. This reduction in time has many advantages for the user.

  If the authentication is successful, access permission is set in the IC card 2 (C3), and the vehicle-mounted device 1 reads card information (for example, payment information) from the IC card 2 (B16). Since this process enables ETC settlement, control is performed to notify that ETC is available (B17). In accordance with this notification control, ETC availability notification is performed both in display and in sound via the display unit 18 and speaker 23 of the vehicle-mounted device 1 or the display unit and speaker in the navigation device 5 (D4).

(2) Example of operation when IC card service is not used by wireless communication The processing shown in B1 to B6, C1, D1, and D2 shown in FIG. 4 is the same as the processing shown in FIG. Omitted.

A case will be described in which wireless communication is started with a roadside machine 3 that does not use an ETC application, such as a roadside machine 3 for credit settlement after the ETC payment is possible.
First, the vehicle-mounted device 1 performs control to notify that the use of ETC has become impossible (B7). In accordance with this notification control, an ETC use disapproval notification is given both via display and voice via the display unit 18 and speaker 23 of the vehicle-mounted device 1 or the display unit and speaker of the navigation device 5 (D3). These processes are the same as those shown in FIG.

  Then, the process regarding a data communication service is performed in the onboard equipment 1 (A21), and the onboard equipment 1 performs the process (data communication) corresponding to the service (B21). Then, the process regarding a user notification service is performed in the onboard equipment 1 (A22), and the onboard equipment 1 performs user notification control which is a process corresponding to the service (B22). In accordance with this notification control, ETC availability notification is performed both in display and through the display unit 18 and the speaker 23 of the vehicle-mounted device 1 or the display unit and the speaker in the navigation device 5 (D21).

  When such a series of wireless communication between the roadside device 3 and the vehicle-mounted device 1 is completed, the vehicle-mounted device 1 determines the use of the IC card 2 (B23). As described above, this use determination may be performed based on the state of the flag indicating “re-authentication required” described when the IC card is deactivated in B9 of FIG. 2, for example.

  In the case shown in FIG. 4, since the IC card 2 is not used, the IC card 2 does not need to be re-authenticated, so control is performed to notify that the ETC can be used (B24). In accordance with this notification control, an ETC availability notification is performed both in display and through the display unit 18 and the speaker 23 of the vehicle-mounted device 1 or the display unit and the speaker in the navigation device 5 (D22).

(3) Processing in the vehicle-mounted device 1 when a series of wireless communication between the road device 3 and the vehicle-mounted device 1 is completed. Then, after performing wireless communication other than the road device 3 and the ETC, it is executed in the vehicle-mounted device 1 The process will be described with reference to the flowchart of FIG.

  First, it is determined whether or not the IC card 2 is used (S10). As described above, this determination may be performed based on the state of the flag indicating “re-authentication required” described when the IC card is deactivated in B9 of FIG. If the IC card 2 is used (S10: YES), the process proceeds to S20. If the IC card 2 is not used (S10: NO), the process proceeds to S110 as it is, and an ETC availability notification is performed. As described above, the availability notification is performed both by display and voice via the display unit 18 and the speaker 23 of the vehicle-mounted device 1 or the display unit and the speaker of the navigation device 5.

  Next, it is determined whether or not the IC card 2 is in an activated state (S20). If the IC card 2 is activated (S20: YES), the IC card 2 is deactivated (S30), and then the IC card 2 is reactivated (S40). On the other hand, if the IC card 2 is not activated (S20: NO), the IC card 2 is reactivated (S50).

  It is determined whether the reactivation of the IC card 2 is successful (S60). If the reactivation is successful (S60: YES), the IC card 2 is re-authenticated (S70). It is determined whether re-authentication of the IC card 2 is successful (S80). If re-authentication is successful (S80: YES), information is re-read from the IC card 2 (S90). It is determined whether or not the re-reading of information is successful (S100). If the re-reading is successful (S100: YES), display is performed via the display unit 18 and the speaker 23 or the display unit and the speaker in the navigation device 5. And ETC availability notification both by voice and voice (S110). In this way, an ETC settlement process is possible.

  On the other hand, if a negative determination is made in S60, S80, S100, the process proceeds to S120, and the IC card 2 is displayed and sounded via the display unit 18 and the speaker 23 or the display unit and the speaker in the navigation device 5. Notification of access failure to. In addition, the case of negative determination in S60 is a case where the reactivation fails or the IC card 2 is pulled out. The case of negative determination in S80 is a case where re-authentication fails or the IC card 2 is pulled out. In addition, the negative determination in S100 is a case where the re-reading fails or the IC card 2 is pulled out.

[Effects of OBE 1]
(1) According to the vehicle-mounted device 1 of the present embodiment, after the ignition switch 7 is turned on and power supply to each part of the vehicle-mounted device 1 is started (power ON state), the IC card 2 is connected to the IC card connector 15 by the user. When the card is inserted, activation (B2), type determination (B3), authentication (B4), information reading (B5), and ETC availability notification (B6) of the IC card 2 are performed.
Therefore, when it becomes necessary to perform an ETC settlement process thereafter, the process can be executed immediately.

  Thereafter, when executing an application process that causes access to the IC card 2 other than the ETC settlement process, the IC card 2 is once deactivated (B9) and activated again (B10). As described above, there are naturally cases where application processing other than the ETC payment processing is executed in such a state that the ETC payment processing becomes possible when the power is turned on. If no action is taken here, it will lead to leakage of information necessary for ETC payment processing. Therefore, when the application 1 other than the ETC payment process is executed, the vehicle-mounted device 1 is executed after the IC card is once deactivated and activated again, thereby preventing leakage of information necessary for the ETC payment process. .

  When the control based on the application process other than the ETC settlement process is completed, it is determined whether or not the access to the IC card 2 has occurred in the application process (B13), and the access to the IC card 2 has occurred. In this case, after reactivation of the IC card 2 (B14), re-authentication of the IC card 2 (B15), information rereading (B16), and ETC availability notification (B17) are executed. As a result, if it becomes necessary to perform ETC settlement processing thereafter, the processing can be executed immediately.

  Thus, according to the vehicle-mounted device 1, it is possible to keep the convenience at the time of using the ETC payment processing function while the so-called multi-function IC card 2 remains attached to the vehicle-mounted device 1.

  (2) As a user, it is also one of the concerns whether the ETC payment process, which is the application process that is given the highest priority, is executable or not. Therefore, according to the vehicle-mounted device 1 of the present embodiment, when the ETC payment processing function becomes available or unavailable, the display unit 18 and the speaker 23 of the vehicle-mounted device 1 or the display on the navigation device 5 Notification is performed by both display and audio via the unit and the speaker.

  (3) Among application processes other than the ETC payment process, there is an application process in which access to the IC card 2 does not occur. In that case, since there is no fear of leakage of information in the IC card 2, the necessity for deactivation is low. In that case, if the activation state is maintained without performing the activation, the authentication process is performed before that, so there is no need to re-authenticate. Therefore, it is effective for shortening the time until the ETC settlement process can be executed.

  (4) In the present embodiment, ETC settlement processing is assumed as the highest priority application processing. In the case of the ETC payment process, it takes about several seconds to 10 seconds until the ETC payment process can be executed after the IC card 2 is inserted into the IC card connector 15. Therefore, it is effective to make such processing immediately executable.

[Another embodiment]
(1) In the above embodiment, the case where the IC card 2 is inserted into the IC card connector 15 by the user after the ignition switch 7 is turned on and the power supply to each part of the vehicle-mounted device 1 is started (power-on state). Assumed. However, it is also conceivable that the ignition switch 7 is turned on while the IC card 2 is inserted into the IC card connector 15 and power supply to each part of the vehicle-mounted device 1 is started (power ON state). In such a case, when the power is turned on, activation of the IC card 2 (B2), type determination (B3), authentication (B4), information reading (B5), ETC availability notification (B6) Can be done.

  (2) In the said embodiment, the roadside machine 3 was assumed as an example of an external device. However, even if it is other than the road machine 3, it can be an external device. For example, if the navigation device 5 has a settlement function, the same effect can be obtained even when communication with the navigation device 5 connected to the vehicle-mounted device 1 is assumed.

  (3) In the above embodiment, the ETC payment process is assumed as the highest priority application process. Of course, the application process requiring at least the IC card authentication process may be the highest priority application process.
