Next, the processing flow of the payment system will be described.
In the following example, description will be given using an example in which the roadside device 2 is provided at the entrance or exit of the parking lot, and the settlement calculation device 4 calculates the parking fee (payment amount).
First, an ETC card is inserted into the vehicle-mounted device 1. A vehicle on which the vehicle-mounted device 1 is mounted moves and approaches a parking lot where the roadside device 2 is provided. When the vehicle enters the communicable area with the roadside device 2, the roadside device 2 performs DSRC (Dedicated Short Range Communication) communication with the vehicle-mounted device 1, and the controller 13 of the roadside device 2 and the vehicle-mounted device 1 control unit 22. Authentication processing is performed during the period (step S101).

  When the authentication process is completed, the SAM 12 of the vehicle-mounted device 1 acquires information (ETC card reading information) from the memory of the ETC card 10 via the reading unit 11 (step S102). The SAM 12 encrypts the ETC card reading information (step S103), and outputs the encrypted ETC card reading information to the control unit 13. The control unit 13 reads vehicle information (number plate information, vehicle type, etc.) and vehicle-mounted device information recorded in a memory or the like, and wirelessly transmits the vehicle information and vehicle-mounted device information and encrypted ETC card reading information. Output to the communication unit 14. And the radio | wireless communication part 14 transmits vehicle information, vehicle equipment information, and the encrypted ETC card reading information to the roadside machine 2 by DSRC communication (step S104).

  Next, the wireless communication unit 21 of the roadside device 2 receives the vehicle information and the vehicle-mounted device information transmitted from the vehicle-mounted device 1 and the encrypted ETC card reading information. And the control part 22 inputs those information. Then, the control unit 22 outputs the encrypted ETC card reading information to the wired communication unit 25, and the wired communication unit 25 transfers the ETC card reading information to the external device 3 (step S105). On the other hand, the control part 32 records the received vehicle information and vehicle equipment information temporarily in memory.

  Next, the communication processing unit 31 of the external device 3 receives the encrypted ETC card reading information transmitted from the roadside device 2, and the control unit 32 acquires the encrypted ETC card reading information. Then, the control unit 32 outputs the encrypted ETC card reading information to the SAM 33. The SAM 33 decrypts the encrypted ETC card reading information and outputs it to the card specific information calculation unit 34 (step S106). Based on the ETC card reading information, the card specifying information calculating unit 34 calculates card specifying information that can specify the ETC card reading information (step S107). For example, an ETC card number (x) included in the ETC card reading information and a fixed value parameter (α) are substituted into a predetermined function f (x, α), and the result is calculated as card specifying information. The card specific information calculation unit 34 records the ETC card reading information and the card specific information in the storage unit 36 in association with each other.

  Then, the card specific information calculation unit 34 outputs the calculated card specific information to the control unit 32, and the control unit 32 sends the card specific information to the roadside device 2 that is the source of the ETC card read information via the communication processing unit 31. Control to send. When the communication processing unit 31 transmits the card specifying information (step S108), the wired communication unit 25 of the roadside device 2 that is the transmission source of the ETC card reading information receives the card specifying information. Then, the control unit 22 acquires the card specifying information, records it in the storage unit 26 in association with the vehicle information or the vehicle-mounted device information temporarily stored in the memory, and settles the payment amount management request including the acquired card specifying information. Output to the forehead management unit 23.

  When the settlement amount management unit 23 of the roadside device 2 inputs a settlement amount management request, the card identification information is read from the information, and the vehicle information or the in-vehicle information recorded in the storage unit 26 is associated with the card identification information. Read vessel information. Then, the settlement amount management unit 23 requests the control unit 22 to transmit the read vehicle information and in-vehicle device information to the settlement calculation device 4. Then, the control unit 22 performs control to transmit the payment amount calculation request including the vehicle information and the vehicle-mounted device information input from the payment amount management unit 23 to the payment calculation apparatus 4 via the wired communication unit 25 (step S109). ). At this time, the settlement amount management unit 23 requests the control unit 22 to transmit a settlement amount calculation request including the card identification information, and the control unit 22 transmits the card identification information, the vehicle information, the in-vehicle device information, Control may be performed to transmit a settlement amount calculation request including the combination to the settlement calculation apparatus 4 via the wired communication unit 25.

  Then, the settlement calculation device 4 makes a settlement amount calculation request including vehicle information and on-vehicle device information or a settlement amount calculation request including a combination of card identification information, vehicle information and on-vehicle device information in the communication processing unit 41. Receive. When the card calculation information is used when the payment calculation device 4 calculates the payment amount, the roadside device 2 transmits a payment amount calculation request including the card specification information to the payment calculation device 4. When the payment calculation device 4 does not use the card specific information for calculating the payment amount, the roadside device 2 transmits a payment amount calculation request not including the card specification information to the payment calculation device 4.

  Here, when the payment calculation device 4 calculates the parking lot usage fee as the payment amount, the roadside machine 2 installed at the entrance and the roadside machine 2 installed at the exit for one vehicle. Each receives two payment amount calculation requests. Accordingly, the settlement amount calculation unit 42 determines whether the settlement amount calculation request received this time is the first settlement amount calculation request or the second settlement amount calculation request (step S110). Specifically, the payment amount calculation unit 42 stores information included in the payment amount calculation request received in the past in a storage unit such as a hard disk or a memory at the time when the payment amount calculation request is received. Then, the settlement amount calculation unit 42 reads the in-vehicle device information and the card identification information from the settlement amount calculation request received this time and matches the in-vehicle device information and the card identification information included in the settlement amount calculation request received in the past. It is determined by comparing with the information stored in the storage unit of its own device.

  Then, the payment amount calculation unit 42, when the information stored in the storage unit of its own device does not exist information that matches the vehicle-mounted device information and the card specific information included in the payment amount calculation request received this time. Determines that the settlement amount calculation request received this time is the first settlement amount calculation request. Then, the settlement amount calculation unit 42 records the information included in the first settlement amount calculation request in the storage unit in association with the reception time. Then, in response to the first payment amount calculation request, the payment amount calculation unit 42 notifies the roadside device 2 of the completion of the processing (step S111). The roadside device 2 transfers the processing completion to the vehicle-mounted device 1 and communication between the vehicle-mounted device 1 and the roadside device 2 at the entrance is completed.

  On the other hand, when the payment amount calculation unit 42 includes information that matches the in-vehicle device information and the card specific information included in the payment amount calculation request received this time in the information stored in the storage unit of the device itself. Determines that the settlement amount calculation request received this time is the second settlement amount calculation request. In this case, the payment amount calculation unit 42 reads from the storage unit the reception time of the payment amount calculation request recorded in the storage unit in association with the first payment amount calculation request. Then, the payment amount calculation unit 42 calculates the difference between the reception time of the first payment amount calculation request and the reception time of the second payment amount calculation request received this time as the parking time (step S112). The payment amount calculation unit 42 may calculate the payment amount according to the vehicle type information included in the received payment amount calculation request.

  Here, the settlement amount calculation unit 42 stores a parking fee that increases every 30 minutes, for example, in a storage unit in association with a parking time at intervals of 30 minutes. Then, the settlement amount calculation unit 42 reads a parking fee associated with an integer obtained by omitting the decimal point of “calculated parking time ÷ 30” from the storage unit, and specifies the parking fee as a settlement amount (step S113). . Alternatively, as another calculation method, the payment amount calculation unit 42 calculates a value obtained by multiplying an integer obtained by omitting the decimal point of “calculated parking time ÷ 30” by a parking fee added every 30 minutes. May be calculated. Then, the settlement amount calculation unit 42 transmits the settlement amount calculation result including the calculated settlement amount to the roadside device 2 that has transmitted the settlement amount calculation request via the communication processing unit 41 (step S114).

  Next, when the settlement amount calculation result is received in the roadside device 2, the control unit 22 reads the settlement amount included in the settlement amount calculation result received in response to the settlement amount calculation request, and outputs it to the settlement amount management unit 23. . Then, the payment amount management unit 23 writes the payment amount in the storage unit 26 in association with the vehicle-mounted device identification information and the card identification information transmitted in the payment amount calculation request. Then, the billing process request unit 24 generates a billing process request including the settlement amount written in the storage unit 26 and the card specifying information recorded in association with the settlement amount, and sends the billing process request to the external device. 3 is notified to the control unit 22. Then, the control unit 22 transmits a charging process request to the external device 3 via the wired communication unit 25 (step S115).

  The external device 3 receives the charge processing request in the communication processing unit 31. Then, the control unit 32 outputs information on the accounting processing request to the accounting processing unit 35. Further, the billing processing unit 35 reads the payment amount and the card specifying information from the billing processing request. Then, the charging processing unit 35 acquires the ETC card reading information recorded in the storage unit 36 in association with the read card specifying information, and the payment amount acquired from the charging processing request. A billing processing request including is generated. Then, the accounting processing unit 35 instructs the control unit 32 to transmit the newly generated accounting processing request to the card company server. Then, the control unit 32 transmits a billing process request to the card company server (step S116).

  Here, the card company server receives the accounting process request, acquires the ETC card reading information and the payment amount included in the accounting process request, and performs the accounting process. More specifically, the ETC card number is obtained from the ETC card reading information, and the payment amount is charged for the ETC card number. Then, the accounting processing completion notification is transmitted to the external device 3. When the external device 3 receives the charging process completion notification (step S117), the control unit 32 transmits the charging process completion notification to the roadside device 2 via the communication processing unit 31 (step S118). And the control part 22 of the roadside machine 2 transmits completion of an accounting process to the vehicle equipment 1 via the wireless communication part 21 (step S119). Thereby, the communication between the roadside device 2 and the vehicle-mounted device 1 at the exit is completed.

  In addition, in the above-mentioned process, the roadside machine 2 was installed in the entrance and exit of a parking lot, and the example in case a payment system is a system for paying the usage fee of a parking lot was demonstrated. However, the configuration of the payment system may be used as a payment system for road tolls, a payment system for payment of merchandise sales at stores, and the like. In this case, the payment system may calculate the payment amount based on the payment amount calculation request received first time and the payment amount calculation request received second time as in step S110 described above, or one payment time The settlement amount may be calculated based only on the amount calculation request. For example, when the settlement amount is determined according to the vehicle type, the settlement calculation device 4 reads the settlement amount according to the vehicle type from the storage unit and transmits the value to the roadside device 2. Alternatively, the purchase product type is included in the payment amount calculation request transmitted from the roadside device 2 to the payment calculation device 4, and the payment calculation device 4 calculates the payment amount based on the purchase product type. Good.
