Description

  The present invention relates to a vehicle-mounted device for an automatic fee collection system.

  Conventionally, ETC (Registered Trademark, the same shall apply hereinafter) processing equipment at entrance gates and exit gates of toll roads, etc. to enter, exit and pay fees while passing through the entrance gate and exit gate non-stop (Electronic Toll Collection: automatic fee collection system) has been put into practical use (for example, see Patent Documents 1 and 2). An IC card called an ETC card can be inserted into an ETC vehicle-mounted device mounted on a vehicle for this ETC. When the ETC on-board unit communicates with the ETC processing unit, the in-card information recorded in the IC card inserted into the ETC on-board unit is transmitted to the ETC processing unit.

  However, in order to ensure security, the IC card must be in the IC card if it does not undergo mutual authentication (hereinafter referred to as card authentication) for confirming that it is a legitimate partner between the ETC onboard device and the IC card. Access (reading or writing) to recorded personal information data is not permitted.

  Therefore, in order to exchange information in the card between the ETC on-board unit and the ETC processing device at the entrance gate or the exit gate (that is, entrance processing or exit processing), the authentication of the ETC card needs to be completed. .

JP 2002-175552 A JP 2000-99785 A

  However, the card authentication takes about several seconds after the ETC card is inserted. Therefore, if the user notices that he / she has forgotten to insert the ETC card immediately before the entrance gate or the exit gate and inserts the ETC card into the ETC on-board device at that time, it may be possible to enter the ETC communication area during card authentication. .

  Here, when the vehicle enters the ETC communication area during the ETC card authentication, and the ETC on-board device and the ETC processing device start communication, the road-side ETC processing device determines that there is no ETC card communication, and the on-vehicle device cannot pass. An instruction is given to the vehicle-mounted device, and the gate is not opened regardless of the success or failure of the subsequent card authentication, and as a result, the driver is forced to stop the vehicle.

  Further, if the communication is not started even if the vehicle enters the ETC communication area during the card authentication, the communication will be performed after the card authentication is completed, so that there is no communication without the ETC card. However, if the card authentication is not completed in time for the passage of the gate, the gate is not opened and the vehicle is forced to stop.

  In either case, although the user thinks that the gate should open because the ETC card is inserted, the gate does not open properly, which may give the user a sense of discomfort and anxiety.

  SUMMARY OF THE INVENTION In view of the above points, the present invention aims to reduce discomfort and anxiety about the gate not opening properly even when a vehicle enters an ETC communication area during card authentication, even though the card is inserted. And

In order to achieve the above object, the invention described in claim 1 is an on-vehicle device for an automatic toll collection system, and information to be transmitted from the on-vehicle device to a roadside processing device (4) of the automatic toll collection system. Based on card authentication processing means (310 to 370) for performing a series of processing for card authentication of the card and a signal received from the processing device (4) when the recorded card is inserted. A determination means (110) for determining whether or not the card authentication processing means (310 to 370) is in a series of processes for the card authentication; and in a series of processes for the card authentication. there wherein based on the determination means (110) determines that said processing unit (4) does not initiate communication with the processing device (4) by not sending a response of the signal received from or or, Yu A warning notification means (180) for performing a warning notification notifying that the chromatography is impassable, on the basis that the said determination means as being in a series of processes for the card authentication (110) determines a warning after notifying means (180) has performed the warning notification, not in the series of processing with the determining means for pre-Symbol card authentication (110) based on the determined, and the processing device (4) It is an onboard equipment provided with the communication start means (120) which starts communication.

  In this way, when the vehicle receives a signal from the processing device (4) during a series of processing for card authentication, the user receives a warning notification, so that the vehicle can be decelerated or stopped to delay gate entry. . Also, even if the vehicle approaches the gate and as a result the gate closes, it will not be uncomfortable. Further, since the vehicle-mounted device does not start communication with the processing device (4), it can start communication after the card authentication ends and pass through the gate.

  In addition, as described in claim 2, a series of processing for the card authentication is performed by performing activation of the card, reading of a card type, and card authentication after the card is mounted. Processing until the reading of information is completed may be performed.

  In addition, the code | symbol in the bracket | parenthesis in the said and the claim shows the correspondence of the term described in the claim, and the concrete thing etc. which illustrate the said term described in embodiment mentioned later. .

It is a figure which shows a card | curd authentication process. It is a figure which shows the communication procedure of the ETC onboard equipment and ETC processing apparatus at the normal time. It is a flowchart of the process which an ETC onboard equipment performs. It is a figure which shows the procedure at the time of receiving the signal 405 from the ETC processing apparatus at the time of card | curd authentication.

  Hereinafter, an embodiment of the present invention will be described. FIG. 1 schematically shows the overall configuration of a communication system according to the present embodiment. In this communication system, a vehicle 2 equipped with an ETC vehicle-mounted device 1 is about to enter a gate (entrance gate or exit gate) of a toll road (entrance toll gate or exit toll gate) equipped with an ETC system. . The toll booth includes a road antenna 3, an ETC processing device 4, a vehicle detector 5, and a start controller 6.

  The ETC processing device 4 installed on the road side is a device that performs billing communication with the ETC vehicle-mounted device 1 that has entered the communicable area (referred to as an ETC communication area) of the road antenna 3 that is also installed on the road side. The vehicle detector 5 includes, for example, an infrared sensor, and outputs a signal to that effect to the ETC processing device 4 when detecting the approach of the vehicle. The start controller 6 controls the behavior of the bar that blocks or opens the passage of the vehicle by changing the inclination based on the control signal input from the ETC processing device 4. The settlement processing center 10 receives billing information from the ETC processing device 4 via the communication network 9 and realizes billing processing based on the billing information.

  FIG. 2 shows a configuration of the ETC vehicle-mounted device 1 mounted on the vehicle 2. The ETC vehicle-mounted device 1 includes an antenna 11, a wireless unit 12, a vehicle-mounted device controller 13, an IC card interface circuit unit 14, an operation unit 15, a display unit 16, an audio circuit 17, and a speaker 18.

  The radio unit 12 performs amplification, frequency conversion, demodulation, A / D conversion, and the like on the signal received by the antenna 11 and outputs the resulting data to the in-vehicle device controller 13. The radio unit 12 performs D / A conversion, modulation, frequency conversion, amplification, and the like on the data input from the in-vehicle device controller 13 and outputs the resulting signal to the antenna 11. The frequency conversion, modulation, and demodulation performed here are based on the DSRC standard. With such a function, the radio unit 11 can exchange signals with the ETC processing device 4 via the antenna 3 in the vicinity.

  The in-vehicle device controller 13 includes a CPU, a RAM, a ROM, and the like (not shown), and executes processing for billing described later by their known operations. The in-vehicle device controller 13 exchanges signals with the wireless unit 12, the IC card interface circuit unit 14, the operation unit 15, the display unit 16, and the audio circuit 17 when executing the processing. The display unit 16 is an image display device. The audio circuit 17 is a device that causes the speaker 18 to output audio in accordance with the control of the in-vehicle device controller 13.

  An IC card 20 for ETC can be inserted into and removed from the IC card interface circuit section 14 (that is, detachable). The IC card interface circuit unit 14 reads data recorded on the IC card 20 physically and electrically connected by being inserted, and writes data to the IC card 20. Here, the ETC IC card 20 is an electronic card that can be carried individually by the user for storing authentication information for charging, charging history information, and the like, and is also referred to as an ETC card.

  The IC card 20 has a CPU, RAM, ROM, EEPROM, and the like. When the CPU executes a program in the ROM, a read command from the in-vehicle device controller 13 via the IC card interface circuit unit 14 is obtained. In response to a write command or the like, various information on the EEPROM is written and various information is written to the EEPROM.

  The in-vehicle device controller 13 includes a CPU, ROM, and RAM (not shown). The CPU executes a program read from the ROM, reads information from the ROM and RAM, and writes information to the RAM. If necessary, information is written to and read from the IC card 20 connected to the IC card interface circuit unit 14.

  Specifically, when the IC card 20 is inserted into the IC card interface circuit unit 14, the in-vehicle device controller 13 reads the data recorded on the IC card 20 and copies it on the RAM. FIG. 3 is a sequence diagram showing the exchange of signals between the ETC vehicle-mounted device 1 and the IC cart in the period from when the IC card 20 is inserted into the IC card interface circuit unit 14 until the data is copied onto the RAM. As shown.

  As shown in FIG. 3, when the IC card 20 is inserted into the IC card interface circuit unit 14, power is supplied to the IC card from a power supply unit (not shown) of the ETC vehicle-mounted device 1, and the vehicle-mounted device controller 13 connects the IC card 20. By outputting a signal for resetting, the IC card 20 is activated (corresponding to the signal 310). When the notification that the IC card 20 is activated is output to the in-vehicle device controller 13 (corresponding to the signal 320), the in-vehicle device controller 13 then outputs a card type read command to the IC card 20 (signal The IC card 20 outputs card type information to the in-vehicle device controller 13 in accordance with the command (corresponding to the signal 340).

  Subsequently, the in-vehicle device controller 13 and the IC card 20 exchange a plurality of data (corresponding to the processing 350) for mutual authentication. As the card authentication method, for example, a challenge / response authentication method is used. This mutual authentication process corresponds to card authentication.

  When it is confirmed by the card authentication that the two are legitimate parties, the in-vehicle device controller 13 then transmits a read command of information in the IC card 20 such as personal information to the IC card 20 (corresponding to the signal 360). ). Then, the IC card 20 outputs data to the in-vehicle device controller 13 in accordance with the command (corresponding to the signal 370).

  In this way, data reading by the in-vehicle device controller 13 is realized. If the above-described card authentication is not successful, the IC card 20 returns a rejection signal in response to commands for reading and writing data related to personal information from the in-vehicle device controller 13. Therefore, the ETC in-vehicle device 1 can perform data access such as data writing and reading with respect to the IC card 20 only after the card authentication.

  FIG. 4 shows a sequence example of a communication procedure performed by the ETC on-board unit 1 and the ETC processing device 4 when the ETC on-board unit 1 having the above configuration passes near the gate antenna 3 on the gate. . The operation of the ETC vehicle-mounted device 1 and the ETC processing device during ETC processing will be described with reference to this figure.

  First, as described above, the in-vehicle device controller 13 of the ETC on-vehicle device 1 performs card authentication processing with the IC card 20 when the IC card 20 is inserted into the IC card interface circuit unit 14 in advance. 20 data are read (corresponding to the signal 401). By reading the data of the IC card 20, a series of processing for card authentication is completed.

  Subsequently, when the vehicle 2 enters the ETC communication area, the in-vehicle device controller 13 receives an FCM (Flame Control Message) transmitted from the ETC processing device 4 via the road antenna 3 (corresponding to the signal 405). If it is a regular FCM, data exchange (corresponding to the FCMC signal 405, ACTC signal 410, BST signal 415, and VST signal 420) with the ETC processing device 4 is transmitted to the antenna 11, wireless This is performed via the unit 12. If the processing of the in-vehicle device controller 13 so far is successful, then the ETC communication processing starts.

  In the ETC communication processing, the in-vehicle device controller 13 exchanges data for charging with the ETC processing device 4 via the antenna 11 and the wireless unit 12 as shown in FIG. Specifically, the Action1. req signal 425, Action2. req signal 435, Action3. req signal 445, Action4. req signal 455 is received, and Action1. res signal 430, Action2. res signal 440, Action3. res signal 450, Action4. A res signal 460 is transmitted. Here, Action1. req signal 425, Action1. The exchange of the res signal 430 is an exchange of data for mutual authentication between the ETC vehicle-mounted device 1 and the ETC processing device 4. req signal 435, Action2. The exchange of the res signal 440 is an exchange of data for transmission of the vehicle possession information from the ETC on-board unit 1 to the ETC processing device 4. req signal 445, Action3. The exchange of the res signal 450 is an exchange of data for transmission of tollgate information from the ETC processing device 4 to the ETC on-board unit 1. req signal 455, Action4. The exchange of the res signal 460 is an exchange of data for notifying the ETC processing result between the ETC on-board unit 1 and the ETC processing device 4.

  And Action4. The req signal 455 includes a write command for requesting to write the data of the ETC processing result to the IC card. Based on this write command, the in-vehicle device controller 13 outputs data of the ETC processing result and a command requesting to write the data to the IC card (corresponding to the signal 458). Thereafter, Event Report .. sent from the ETC processing apparatus. When the in-vehicle device controller 13 receives the req signal 465, the group of communications for the ETC process ends.

  FIG. 5 shows a process executed by the vehicle-mounted device controller 13 in order to realize communication between the ETC vehicle-mounted device 1 and the ETC processing device 4 as shown in FIG.

  The in-vehicle device controller 13 starts the processing of FIG. 5 based on the fact that the vehicle 2 approaches the toll gate and enters the ETC communication area and receives the FCMC signal 405 from the ETC processing device 4 via the road antenna 3. . Since the in-vehicle device controller 13 performs the process of FIG. 5 in parallel with the series of processes for card authentication shown in FIG. 3, the series of processes for card authentication of FIG. 3 and the processes of FIG. Can be executed in multitasking.

  When the in-vehicle device controller 13 starts the processing in FIG. 5, first, in step 110, the in-vehicle device controller 13 determines whether or not a series of processing for card authentication (that is, processing in FIG. 3) is in progress. A series of processing for card authentication is processing from the time when the IC card 20 is mounted until the reading of the card information of the IC card 20 is completed through activation of the IC card 20, reading of the card type, and card authentication. It is. Therefore, whether or not a series of processing for card authentication is completed is determined by whether or not the card information reading in FIG. 3 is completed. In a normal case, the IC card 20 is inserted into the ETC on-board unit 1 and attached to the IC card interface circuit unit 14 before the vehicle 2 approaches the toll gate. Therefore, when the vehicle 2 enters the ETC communication area. Normally, a series of processing for card authentication has already been completed. Note that a series of processing for card authentication is normally continued for several seconds.

  If a series of processing for card authentication has already been completed, it is determined that a series of processing for card authentication is not in progress, and then the process proceeds to step 120 to communicate with the ETC processing device 4 after the ACTC signal 410. Start and exchange signals 410-465 as shown in FIG.

  When the signal 465 is received, the process proceeds to step 130 to determine whether or not the communication is normally completed. If completed, the process proceeds to step 140 and the ETC is communicated with the ETC processing device 4. Based on the in-vehicle device instruction received from the processing device 4, it is determined whether or not the gate can be passed. In the normal notification, a message indicating that the gate can be passed and a charge amount are displayed on the display unit 16 as characters or images, or are output to the speaker 18 using the audio circuit 17.

  If it is determined in step 130 that the communication has not been completed normally and if it is determined in step 140 that the gate is not allowed to pass, the process proceeds to step 160 and a warning notification is given. In the warning notification, a message indicating that the gate is not allowed to pass is displayed on the display unit 16 with characters or images, or is output to the speaker 18 using the audio circuit 17. After steps 150 and 160, the process of FIG.

  Here, a case where it is determined in step 110 that a series of processing for card authentication is being performed will be described. A series of processing for card authentication takes about several seconds after the IC card 20 is inserted. Therefore, when the user notices that he / she has forgotten to insert the IC card 20 just before the gate, and the IC card 20 is inserted into the ETC on-board unit 1 at that time, as shown in FIG. The ETC communication area may be entered and the FCMC signal 405 may be received from the ETC processing device 4.

  In this case, in step 110 immediately after starting the processing of FIG. 5, it is determined that a series of processing for card authentication is in progress, and then the processing proceeds to step 170 to determine whether or not a warning notification is currently being issued. judge. In step 170 for the first time after starting the processing of FIG. 5, it is determined that a warning notification has not yet been made, and the process proceeds to step 180.

  In step 180, a warning notification is started (see process 470 in FIG. 6). In the warning notification, a message indicating that the gate cannot be passed and a message indicating that a series of processes for card authentication are being performed are displayed on the display unit 16 in characters or images, or a voice is displayed. The circuit 17 is used to output sound to the speaker 18. Following step 180, the process returns to step 110.

  Even if the process returns to step 110, the process proceeds from step 110 to step 170 while the series of processes for card authentication continues. In the second and subsequent steps 170, since the warning notification has already been started, it is determined that the warning notification is being performed, and the processing returns to step 110. Thus, while the series of processing for card authentication continues, the warning notification started in step 180 continues and the processing repeats steps 110 and 170.

  In this way, since the ACTC signal 419 is not transmitted to the ETC processing device 4 during a series of processing for card authentication, the ETC on-board unit 1 does not start communication with the ETC processing device 4 or the display unit 16 or The voice circuit 17 notifies the user of a warning.

  As described above, when the vehicle 2 enters the ETC communication area during a series of processing for card authentication, the user receives a warning notification, so that the vehicle 2 can be decelerated or stopped to delay gate entry. Further, even when the vehicle 2 approaches the gate and as a result, the vehicle detector 5 detects the vehicle 2 and the bar of the start controller 6 goes down, there is no sense of discomfort.

  Moreover, since the ETC onboard equipment 1 does not start communication with the ETC processing apparatus 4, it can start communication and pass through a gate after completion | finish of a series of processes for card | curd authentication. If the ETC on-board device 1 starts communication with the ETC processing device 4, the information in the IC card 20 is not transmitted from the ETC on-board device 1 to the ETC processing device 4, so the ETC processing device 4 determines that there is no communication with the ETC card. The in-vehicle device instruction that is impassable is instructed to the on-vehicle device, and the gate is not opened regardless of the success or failure of the subsequent card authentication, and the vehicle is forced to stop.

  On the other hand, in this embodiment, the ETC vehicle-mounted device 1 does not start communication with the ETC processing device 4 during warning notification. Therefore, when the series of processing for card authentication is completed, the in-vehicle device controller 13 determines in step 110 that the series of processing for card authentication is not in progress, and subsequently executes step 120 and the subsequent steps. As described above, communication with the ETC processing device 4 is realized, the bar of the start controller 6 is raised, and the vehicle 2 can pass through the gate.

  In the above embodiment, the ETC in-vehicle device 1 functions as an example of the card authentication processing means (310 to 370) by performing the process of FIG. 3, and the determination means by executing step 110 of FIG. It functions as an example, functions as an example of a warning notification unit by executing step 180, and functions as an example of a communication start unit by executing step 120.
