Description

The present invention relates to an in-vehicle device used in an automatic fee payment system that automatically pays a toll on a toll road or a fee in a store in a parking area.

  Sending and receiving information between the on-board unit installed in the vehicle and the roadside antenna installed in the toll booth instead of temporarily stopping at the toll booth and paying the toll for smooth toll payment on the toll road There is an automatic toll payment system called ETC (Electronic Toll Collection System. ETC is a registered trademark of the Foundation for Promotion of Road System Advancement). As described in detail in Non-Patent Document 1 below, ETC is a short-range wireless communication (short-range wireless communication) between a roadside antenna provided at a settlement place such as a toll booth and an in-vehicle device installed in a vehicle. Wireless communication is a system that settles tolls by transmitting and receiving information using DSRC (Dedicated Short Range Communications), wireless LAN, infrared communication, Bluetooth, etc.) . In this specification, the automatic fee payment system refers to a system that performs settlement by transmitting and receiving information between the vehicle-mounted device and the roadside antenna using short-range wireless communication.

  In such an automatic fee payment system, by inserting a dedicated credit card (commonly known as an ETC card) into the vehicle-mounted device installed in the vehicle, when the vehicle approaches the roadside antenna, communication by short-range wireless communication is automatically started. In addition, payment of tolls etc. can be made. When the user gets out of the vehicle, the ETC card is removed from the in-vehicle device and stored in order to prevent the ETC card from being stolen.

  In recent years, in order to promote the use of automatic fee payment systems, not only toll payments for toll roads, but also for payments at various facilities such as interchanges with roadside antennas and stores in parking areas. It is considered to be able to do this.

Japanese Patent Application No. 2002-313705 Japanese Patent Application No. 2002-313709 Japanese Patent Application No. 2002-313880 Japanese Patent Application No. 2002-313883 “ETC Handbook” published by the Road System Advancement Promotion Organization, issued by the Road System Advancement Promotion Organization, April 2002, p. 10-42

  However, in the current system in which the ETC card must be inserted into the on-vehicle device every time the automatic fee payment system is used as described above, it is possible to forget to insert the ETC card into the on-vehicle device and approach the roadside antenna. However, in such a case, since the automatic fee payment system cannot be used for settlement, there is a risk that the gate provided at the toll gate or the like will not rise and an accident such as a collision with the gate will be caused as it is.

  Furthermore, since the ETC card is a toll road payment-only card, it cannot be used for payments at various facilities such as the above-mentioned interchanges and stores in the parking area. Need to be inserted into the vessel.

  In other words, when paying for tolls on toll roads, insert an ETC card into the vehicle-mounted device, and when paying charges at various other facilities, remove the ETC card and insert a new credit card. When paying tolls for toll roads again, it is necessary to repeat the operation of inserting the ETC card into the vehicle-mounted device again. Performing such a complicated operation has a risk of distracting the driver's attention.

  In addition, there is also a problem that when the use of the vehicle-mounted device using the conventional ETC card is started, the work for setting up the vehicle-mounted device has to be performed at a dedicated store or the like.

  Therefore, the present inventors do not use an ETC card or a credit card as in the past, but by mounting an IC chip recording such information on the vehicle-mounted device, without performing work such as card replacement, We have invented an in-vehicle device that can realize both toll payment on toll roads and payments at various facilities.

The modem 3 has means for performing ASK (Amplitude Shift Keying) modulation / demodulation for settlement of tolls on toll roads and means for performing QPSK (Quadrature Phase Shift Keying) modulation / demodulation for settlement of charges at various facilities using credit cards. is doing. The reason for having two modulation / demodulation methods in the modulation / demodulation unit 3 is that ASK modulation / demodulation is used for toll payment on toll roads, and QPSK modulation / demodulation is used otherwise. In the present invention, the case of the QPSK modulation / demodulation method has been described as the modulation / demodulation method in the case of charge settlement at various facilities using a credit card, but other modulation / demodulation methods may be used.

  The IC chip unit 8 stores ETC information recorded in the ETC card, such as an ETC card number, an in-vehicle device number, a vehicle registration number, etc., and credit card information such as a credit card number, expiration date, etc. IC chip recording in the recording area.

  The security module unit 7 performs ETC information (ETC card number, ETC card number, This is means for encrypting the vehicle-mounted device number, vehicle registration number, etc.). The encrypted ETC information is modulated / demodulated by the ASK modulation / demodulation method of the modulation / demodulation unit 3 and then transmitted from the antenna unit 2 to the roadside antenna 12.

  In addition, the processing result and ETC information related to toll road toll settlement received by the antenna unit 2 is modulated / demodulated by the modem unit 3 according to the ASK modulation / demodulation method, and then decrypted by the security module unit 7 according to the security format described above. Is recorded in the IC chip unit 8.

  The switch unit 6 extracts the card information (credit card number, expiry date, etc.) recorded in the IC chip unit 8 without going through the security module unit 7 when performing payment at various facilities using a credit card. It is means to switch so as to. Accordingly, the switch unit 6 switches to extract the ETC information recorded in the IC chip unit 8 via the security module unit 7 when performing toll payment on the toll road, otherwise, Also, it plays a role of a switch for switching so that card information recorded in the IC chip unit 8 is extracted without going through the security module unit 7.

  The control processing unit 4 is a means for controlling the vehicle-mounted device 1, and when performing toll payment on a toll road, the control processing unit 4 stores the ETC information recorded in the IC chip unit 8. A command for switching the switch unit 6 is transmitted so as to be extracted via the security module unit 7, and a command for modulation / demodulation by the ASK modulation / demodulation method is transmitted to the modulation / demodulation unit 3. On the other hand, in the case where payment is made at various facilities using a credit card, the control processing unit 4 is configured to extract the card information recorded in the IC chip unit 8 without using the security module unit 7. 6 is transmitted, and an instruction to perform modulation / demodulation by the QPSK modulation / demodulation method is transmitted to the modulation / demodulation unit 3.

  Next, the flow of processing in the vehicle-mounted device 1 used in the automatic fee payment system of the present invention will be described with reference to the flowcharts of FIGS. 2 and 3 and the system configuration diagram of FIG.

  A vehicle equipped with the vehicle-mounted device 1 approaches the roadside antenna 12 used in the automatic fee payment system (S100). The roadside antenna 12 may be installed at an interchange or a toll booth for payment of tolls on toll roads, or may be installed near a store or the like for payment by credit card. good.

  When the vehicle-mounted device 1 reaches the communication area of the roadside antenna 12, communication by short-range wireless communication is started between the vehicle-mounted device 1 and the roadside antenna 12 (S110). When DSRC is used for short-range wireless communication, this communication is automatically started, and when using other than that, for example, a button indicating “communication start” provided on the vehicle-mounted device 1 is pressed. The communication may be started by an operation such as.

  When the short-range wireless communication is toll road payment settlement (S120), the control processing unit 4 switches the switch to extract ETC information from the switch unit 6 via the security module unit 7 ( S130).

  Since the ETC processing unit 5 is set by the switch unit 6 so as to pass through the security module unit 7, the ETC information is extracted from the IC chip unit 8 (S140), and the security module unit 7 extracts the ETC information. The ETC information is encrypted according to the security format (encryption format) used in the payment system (S150).

  Then, the ETC processing unit 5 transmits the encrypted ETC information to the modem unit 3. Further, since the control processing unit 4 is toll payment on a toll road, the control processing unit 4 transmits a command to perform modulation / demodulation by the ASK modulation / demodulation method to the modem unit 3.

  The modem 3 modulates / demodulates the encrypted ETC information received from the ETC processor 5 by the modulation / demodulation method (ASK modulation / demodulation method) according to the command from the control processing unit 4 (S160).

  On the other hand, when the short-range wireless communication is other than toll payment for toll roads, for example, in the case of toll payment by credit card at various facilities, the control processing unit 4 does not pass the security module unit 7 with respect to the switch unit 6. The switch is switched as described above (S170).

  Since the ETC processing unit 5 is set so that the switch unit 6 does not pass through the security module unit 7, the card information is extracted from the IC chip unit 8 (S 180), and is transmitted to the modem unit 3. At this time, the ETC processing unit 5 may perform original encryption processing on the card information. Further, since the control processing unit 4 is other than toll payment on the toll road, the control processing unit 4 transmits a command for modulation / demodulation by the QPSK modulation / demodulation method to the modulation / demodulation unit 3.

  The modem unit 3 modulates / demodulates the card information received from the ETC processing unit 5 by the modulation / demodulation method (QPSK modulation / demodulation method) in accordance with the command from the control processing unit 4 (S190).

  The encrypted ETC information and card information modulated / demodulated by the modem unit 3 are transmitted from the antenna unit 2 to the roadside antenna 12 (S200).

  In this way, by transmitting the ETC information and the card information from the vehicle-mounted device 1 to the roadside antenna 12, the roadside antenna 12 receives the ETC information and the card information, and the payment server performs the toll payment on the toll road. , Other than that, it is transmitted to the settlement server that performs the fee settlement. Thereby, each settlement is performed.

  Thereafter, the processing result information is transmitted to the roadside antenna 12 from the payment server that performs toll payment for toll roads, and the payment server that performs other fee payments, and the short distance from the roadside antenna 12 to the vehicle-mounted device 1 Information is transmitted by wireless communication. The vehicle-mounted device 1 receives this information by short-range wireless communication (S210).

  In the case of payment for tolls on toll roads (S220), the control processing unit 4 transmits an instruction to perform modulation / demodulation by the ASK modulation / demodulation method to the modulation / demodulation unit 3, so Modulates and demodulates the received information using the ASK modulation and demodulation method (S230).

  In the switch unit 6, since the control processing unit 4 is set so as to pass through the security module unit 7, the ETC processing unit 5 transmits the modulated / demodulated information to the security module unit 7, and is used in the automatic fee payment system. The received information is decrypted according to the security format (encryption format) (S240). Then, the decrypted information is recorded in an area for recording information when the toll road toll settlement of the IC chip unit 8 is performed (S260).

  On the other hand, in cases other than payment for tolls on toll roads (S220), for example, for payments at various facilities, the control processing unit 4 transmits a command for modulation / demodulation using the QPSK modulation / demodulation method to the modulation / demodulation unit 3. The modulation / demodulation unit 3 that has received information from the antenna unit 2 modulates / demodulates the received information using the QPSK modulation / demodulation method (S250).

  Since the control processing unit 4 is set not to go through the security module unit 7 in the switch unit 6, the ETC processing unit 5 performs other than toll payment on the toll road of the IC chip unit 8 with respect to the modulated / demodulated information. Is recorded in the recording area (S260). The ETC processing unit 5 records the modulated / demodulated information in the IC chip unit 8 after the decryption process when the information is subjected to a predetermined encryption process before the information is recorded in the IC chip unit 8.

  After that, the ETC processing unit 5 displays the processing result information on the display of the vehicle-mounted device 1 through the control processing unit 4 and reproduces the sound on the speaker to notify the driver of that.

  The vehicle-mounted device 1 of the present invention may be connectable to a car navigation device via the external interface unit 9. That is, the display and the sound reproduction may be performed by the display and the speaker of the vehicle-mounted device 1, and the display and the sound reproduction may be performed by the display and the speaker of the car navigation device via the external interface unit 9 of the vehicle-mounted device 1. In this case, the ETC processing unit 5 transmits processing result information to the control processing unit 4, and the control processing unit 4 transmits processing result information to the car navigation device via the external interface unit 9. The display and sound reproduction are performed by the display and speaker of the car navigation device.

  Next, the case where the vehicle-mounted device 1 of the present invention is mounted on a vehicle and a setup operation is performed will be described. The setup work refers to a process of mounting the vehicle-mounted device 1 on the vehicle and making the vehicle-mounted device 1 available. FIG. 4 shows an example of the system configuration in this case.

Enter from.

  The control processing unit 4 that has received this input via the external interface unit 9 transmits it to the ETC processing unit 5, and the ETC processing unit 5 stores the reception in the recording area in which the ETC information of the IC chip unit 8 is recorded. Information (ETC card number, vehicle-mounted device number, vehicle registration number, etc.) is recorded.

  In addition, the computer terminal 13 connected to the vehicle-mounted device 1 also records the ETC recorded in the IC chip unit 8 via the network such as the Internet, against the ETC management company system 14 (computer system of the management company that operates ETC). Send information. The ETC management company system 14 that has received this records it. The registration work for the ETC management company system 14 makes it possible to charge the user for a fee for a toll road or the like.

  Conventionally, ETC information has been registered in the ETC card to be inserted into the vehicle-mounted device 1, but in such a case, a dedicated device (IC card writing device) for recording on the ETC card is required and set up. The place where work could be done was limited. As described above, by registering ETC information from the computer terminal 13 to the IC chip unit 8 and the ETC management company system 14 via the external interface unit 9 as described above, any computer terminal 13 has an interface. Even in such places, setup work can be easily performed. In particular, by using USB (Universal Serial Bus) for the external interface unit 9 of the vehicle-mounted device 1, any computer terminal 13 can be easily connected as long as it has a USB connection terminal.
