Description

  The present invention relates to an on-board ETC device installed in a vehicle and used to automatically collect tolls on toll roads.

  In recent years, ETC systems that automatically collect tolls on toll roads have been applied to many toll roads. In this ETC system, when a vehicle passes through a toll gate on a toll road, a dedicated onboard device installed in the vehicle (hereinafter referred to as an ETC onboard device) and a roadside device installed in the toll gate. And wirelessly communicate information about tolls. At this time, a dedicated IC card (hereinafter referred to as an ETC card) must be inserted into the ETC on-board device, and the ID for identifying the ETC card as well as information on the toll is also subject to wireless communication. It has become. An account registered by the user is assigned to the ETC card, and the toll gate side deducts the toll from this account.

  By the way, this ETC card can be basically used for any ETC on-board device to settle tolls, and there are some which are also used as credit cards. Therefore, it is necessary to pay close attention to security. Here, regarding the security of the ETC card, the following technologies are introduced (Patent Document 1 and Patent Document 2).

  In the ETC vehicle-mounted device of Patent Document 1, when the ETC card is inserted when the accessory power supply of the vehicle is cut off, the user is notified of that fact. This prevents the user from forgetting to remove the ETC card when the user leaves the vehicle.

Moreover, in the ETC onboard equipment of patent document 2, it divides into the main-body part fixed to a vehicle, and the portable part which a user carries, and an ETC card can be inserted in this portable part. The main body and the portable unit can perform wireless communication over a short distance. And the main-body part can read / write the ETC card inserted in the portable part via the communication line in the state where the portable part and the communication line are established. That is, the toll on the toll road can be automatically collected in the same manner as when an ETC card is inserted into a normal ETC on-vehicle device body. In addition, since the user always carries the portable unit in which the ETC card is inserted, the ETC card is not left in the vehicle when the user leaves the vehicle.

  As described above, both the ETC in-vehicle devices of Patent Document 1 and Patent Document 2 prevent the user from leaving the vehicle while the ETC card is left in the vehicle.

  However, when using the ETC vehicle-mounted device of Patent Document 1, when the user leaves the vehicle, it is necessary to remove the ETC card from the ETC vehicle-mounted device each time. Must be inserted into the vessel. Therefore, the insertion / removal operation of the ETC card is troublesome. In addition, when the user returns to the vehicle, the user may forget to insert the ETC card. In this case, payment of tolls on toll roads cannot be performed normally.

  Moreover, when using the ETC onboard equipment of patent document 2, when a user leaves | separates from a vehicle, it may happen that the portable part itself in which the ETC card is inserted is left in the vehicle. In this case, there is a risk of theft of the ETC card.

  The present invention has been made in view of the above problems, and it is possible to reliably prevent an ETC card from being used without permission by another person without placing a burden on the user than before. It aims at providing onboard equipment.

In order to achieve the above object, the ETC on-board device of claim 1 is installed in a vehicle and used for automatically collecting tolls on toll roads. In the ETC on-vehicle device, a card insertion slot for inserting an ETC card; Determining means for determining whether the owner of the ETC card is in the vehicle; and the determining means determines that the owner of the ETC card is not in the vehicle; and When the ETC card is inserted in the card insertion slot, the ETC card is invalidated, and the determination unit is configured to perform wireless communication with a portable terminal having a communication unit over a short distance. Communication means for establishing a communication line, and the communication means automatically establishes a communication line with the portable terminal when the portable terminal is within a predetermined range. When the communication line is established with the portable terminal, it is determined that the owner of the ETC card is in the vehicle, and when the communication line is not established with the portable terminal, the ETC When it is determined that the owner of the card has not boarded the vehicle, and the invalidating means invalidates the ETC card, the determining means causes the owner of the ETC card to board the vehicle. When the invalid ETC card is inserted into the card insertion slot, the invalidation is canceled .

  Here, as a method of invalidating the ETC card, for example, the identification information for identifying the information written in the ETC card is rewritten to another information, and it is not known where the information necessary for the payment is written. Possible ways to do this. In addition, the information written in the ETC card can be directly transferred to the ETC on-board device side, or the identification information for identifying the ETC card can be rewritten, and other ETC on-board devices cannot recognize the ETC card. You may do it. In addition, any method may be used as long as it is not possible to charge using an ETC card.

As a result, even if the owner of the ETC card forgets to remove the ETC card from the ETC on-board device when leaving the vehicle, the ETC card itself becomes invalid, so even if it is stolen, it is used without permission. There is no such thing. Further, since it is not necessary to insert and remove the ETC card from the ETC on-vehicle device, there is no burden on the owner of the ETC card.
Furthermore, by having the owner of the ETC card carry the mobile terminal, the ETC on-board device can identify whether or not the owner is in the vehicle. In addition, as a method of performing wireless communication between short distances, for example, a method using a well-known Bluetooth (registered trademark, hereinafter omitted) communication method can be cited. Moreover, as a portable terminal, the mobile telephone which incorporated the Bluetooth communication apparatus is mentioned, for example. In this case, since the owner of the ETC card is normally carried by the owner of the ETC card in this case, when the owner of the ETC card leaves the vehicle, the mobile phone itself is rarely left in the vehicle. That is, it is possible to more reliably identify whether the owner of the ETC card is in the vehicle.
Further, in the first aspect of the present invention, as described above, the communication means automatically establishes a communication line with the portable terminal when the portable terminal is within a predetermined range. As a method for automatically establishing a communication line with a portable terminal, a signal for establishing a communication line is periodically transmitted from the host side as is generally used in the Bluetooth communication system, and the client side (mobile There is a method of performing a process for establishing a communication line when the terminal) receives this signal. As a result, if the owner of the ETC card carries the mobile terminal, the owner can unconsciously identify whether the owner is in the vehicle. That is, the security of the ETC card can be improved unconsciously by the owner of the ETC card.

Furthermore, even if the ETC card owner becomes invalid when the ETC card owner leaves the vehicle, it can be used again when the owner returns to the vehicle. As usual, you can make automatic payments for tolls on toll roads.

In the ETC vehicle-mounted device according to claim 2, when the communication device is not established with the communication device and the communication line is not established by the communication device, the vehicle accessory switch is turned off. It is determined that the owner of the ETC card is not in the vehicle.

Even when the owner of the ETC card is in the vehicle, a communication line with the mobile terminal may not be established because the power of the mobile terminal is not turned on. Until this time, if the ETC card is invalidated, it becomes impossible to settle the toll at the toll gate. For this reason, in the ETC vehicle-mounted device of claim 2 , when it is determined that the owner of the ETC card is not in the vehicle, a condition is added that the accessory switch of the vehicle is turned off. is doing. This is because if the accessory switch for the vehicle is turned off, the possibility that the owner of the ETC card will leave the vehicle increases. Thereby, it can be determined more accurately whether the owner of the ETC card is in the vehicle.

The ETC vehicle-mounted device according to claim 3 includes a registration unit for registering the portable terminal, and the determination unit is configured to establish a communication line with the portable terminal registered by the registration unit by the communication unit. When it is determined that the owner of the ETC card is in the vehicle and a communication line is not established with the registered mobile terminal, the owner of the ETC card is not in the vehicle. It is characterized by determining.

For example, when a general-purpose system such as a Bluetooth communication system is used as a communication system with a mobile terminal, a communication line can be established with any mobile terminal as long as the mobile terminal is compatible with the Bluetooth communication system. Even if the portable terminal that established the communication line is not the portable terminal of the owner of the ETC card, if the owner of the ETC card is identified as being in the vehicle, the ETC card can be secured. It will disappear. In view of the above, in the ETC on-vehicle device of claim 3 , even if a communication line is established with an unregistered portable terminal, it is determined that the owner of the ETC card is not in the vehicle. Yes. As a result, it is possible to more reliably identify whether the owner of the ETC card is in the vehicle. Moreover, since it can be applied to any mobile terminal as long as it is a registered mobile terminal, for example, by registering the mobile terminal of the family of the owner of the ETC card, Even when borrowing and using an ETC card, the security of the ETC card can be improved.

The ETC vehicle-mounted device according to claim 4 , further comprising a notifying means for notifying the owner of the ETC card using the portable terminal when the invalidating means invalidates the ETC card. And

  Thereby, the owner of the ETC card can recognize that the ETC card is invalid even if the user forgot to remove the ETC card from the ETC on-board device when leaving the vehicle. So you can be away from the vehicle with peace of mind. If the owner of the ETC card has not recognized that the ETC card is still inserted, the owner can return to the vehicle to pick up the ETC card again.

The ETC vehicle-mounted device according to claim 5 , wherein when the communication means establishes a communication line with the mobile terminal by the communication means and the ETC card is inserted into the card insertion slot, The terminal is notified that the ETC card is invalidated when the established communication line is disconnected, and when the established communication line is disconnected, the ETC card is connected to the portable terminal. It is characterized by notifying that it has been invalidated.

  Thereby, when the ETC card becomes invalid, the owner can recognize that the ETC card is invalid through the portable terminal even if the owner is away from the vehicle.

The ETC vehicle-mounted device according to claim 6 , wherein the notifying unit has established a communication line with the portable terminal by the communication unit, and the ETC card is informed after the ETC card is invalidated. When the card is removed from the card slot, the mobile terminal is notified that the ETC card has not been invalidated, and a notification that the ETC card has been invalidated when the established communication line is disconnected. It is characterized by being canceled.

  In this way, when the owner of the ETC card leaves the vehicle with the ETC card, the ETC card is not invalidated so that the notification that the ETC card has become invalid is not performed. Yes. Thereby, erroneous notification can be prevented.

  Hereinafter, embodiments of the ETC vehicle-mounted device according to the present invention will be described.

  FIG. 1 is a block diagram showing the overall configuration of the ETC vehicle-mounted device 10 according to the present embodiment. As shown in the figure, the ETC in-vehicle device 10 includes a main body 100, a BT communication device 210, an in-vehicle LAN 220 that electrically connects them, and a portable terminal 240. Hereinafter, these will be described.

  The main body 100 includes an arithmetic processing unit 110, an interface circuit unit 120, and a vehicle I / F 130. The interface circuit unit 120 has a card insertion slot (not shown) into which the ETC card 230 is inserted. When the vehicle passes through the toll gate on the toll road, it is based on an instruction from the arithmetic processing unit 110 described later. Then, information such as a card ID is read from the inserted ETC card 230, or information such as a travel history is written.

  The arithmetic processing unit 110 is a part that performs various processes for automatically paying a toll when the vehicle travels on a toll road, and includes a ROM and a RAM inside. Various arithmetic processes are performed in accordance with the program written in the ROM. For example, when a vehicle passes through a toll booth, necessary information is read from the ETC card 230 via the interface circuit unit 120 and transmitted to the roadside machine, or information sent from the roadside machine is received. Writing to the ETC card 230 is performed.

  In the present embodiment, the arithmetic processing unit 110 invalidates the ETC card 230 when it is determined that the owner of the ETC card 230 is away from the vehicle while the ETC card 230 is inserted into the card insertion slot. It is carried out.

  The vehicle I / F 130 is an interface unit for allowing the arithmetic processing unit 110 to communicate with other devices connected to the in-vehicle LAN 220. In this embodiment, the BT communication device 210 is connected to the in-vehicle LAN 220, and the arithmetic processing unit 110 can freely communicate with the BT communication device 210 via the vehicle I / F 130.

  The BT communication device 210 is a device that performs wireless communication with another terminal having a Bluetooth communication device based on a well-known Bluetooth communication method. This Bluetooth communication system is a kind of short-range communication system, and in this embodiment, the communicable range is approximately in the range of the passenger compartment. Further, the BT communication apparatus 210 can register a terminal that performs wireless communication. As will be described later, based on whether a communication line is established with the registered terminal, the arithmetic processing unit 110 It is determined whether or not the owner of the ETC card 230 is in the vehicle.

  Further, the BT communication device 210 is connected to a power supply for accessories (not shown) of the vehicle, and periodically sends a predetermined signal to the outside while receiving power supply. Whether or not there is a terminal having a Bluetooth communication device.

  The portable terminal 240 has a Bluetooth communication device therein, and can wirelessly communicate with other communication devices having the Bluetooth communication device. In the present embodiment, the portable terminal 240 belongs to the owner of the ETC card 230 and is registered in the BT communication device 210. Therefore, the arithmetic processing unit 110 determines whether or not the owner of the ETC card 230 is in the vehicle based on whether or not a communication line is established with the portable terminal 240. Further, the portable terminal 240 has a display unit 241, and when the ETC card 230 becomes invalid, a message to that effect is displayed on the display unit 241.

  In the present embodiment, the mobile terminal 240 is included in the configuration of the ETC on-vehicle device 10, but a known mobile phone with a Bluetooth communication device may be substituted.

  Next, the operation of the ETC vehicle-mounted device 10 configured as described above will be described.

  FIG. 2 is a sequence diagram showing a communication sequence among the accessory switch (ACC), the ETC card 230, the main body 100, and the portable terminal 240. Hereinafter, description will be given according to this sequence diagram.

  First, when the owner of the ETC card 230 gets into the vehicle and the engine of the vehicle is started (ACC ON), the main body 100 performs a startup process. Specifically, the arithmetic processing part 110 of the main body 100 performs according to the flowchart of FIG.

  In step S10, it is determined whether or not the ETC card 230 is inserted into the card insertion slot. Here, when it is not inserted (negative determination), the subsequent processing is not performed. On the other hand, when the ETC card 230 is inserted (positive determination), the process proceeds to step S11.

  In step S11, based on the Bluetooth communication method, it is determined whether there is a terminal for which a communication line has been established (hereinafter, the state in which the communication line has been established is referred to as BT connection). This can be confirmed by making an inquiry to the BT communication apparatus 210. Here, when there is no BT-connected terminal (negative determination), the subsequent processing is not performed. In this case, processing is performed as a normal ETC vehicle-mounted device. On the other hand, if there is a terminal connected to the BT (positive determination), the process proceeds to step S12.

  Regarding the BT connection method, as described above, the BT communication device 210 periodically receives a predetermined signal in order to detect a terminal having a surrounding BT communication device while receiving power supply. Is outgoing. When the terminal having the BT communication device receives the predetermined signal, the terminal transmits a response signal informing the reception to the BT communication device 210. By receiving this response signal, the BT communication device 210 can recognize that there is a terminal having a BT communication device in the vicinity, and establishes a communication line with this terminal.

  In step S12, it is determined whether or not the BT-connected terminal has been registered in advance. This determination is also made by making an inquiry to the BT communication apparatus 210. If the BT-connected terminal is not registered (negative determination), the subsequent processing is not performed. In this case, since there is a high possibility that a person other than the owner of the ETC card 230 has entered the vehicle, it functions as a normal ETC on-board device. On the other hand, if the BT-connected terminal is registered (affirmative determination), the process proceeds to step S13. In this case, a communication line is established with the portable terminal 240 of the owner of the ETC card 230, that is, the owner of the ETC card 230 gets into the vehicle.

  In step S13, the state of the ETC card 230 relating to whether or not the ETC card 230 is in a charge prohibition state is checked from the ETC card 230 inserted in the card insertion slot. This billing prohibition state refers to a state in which billing cannot be performed using the ETC card 230 through processing described later.

  In step S14, it is determined whether or not the ETC card 230 is in a charge prohibition state. Here, when the ETC card 230 is in the charge prohibition state (affirmation determination), in step S15, the charge prohibition state is canceled and the normal chargeable state is restored. On the other hand, when the ETC card 230 is not in the charge prohibition state (negative determination), in step S16, the state (the processing unit 110) permits the ETC card 230 to be set in the charge prohibition state (hereinafter, referred to as “the charge processing prohibition state”). This state is referred to as “charging prohibition permission state”).

  Returning to the sequence diagram of FIG. 2 again, when the engine of the vehicle is turned off (ACC OFF), the arithmetic processing unit 110 performs “300: Processing when getting off”. Specifically, processing is performed according to the flowchart of FIG.

  First, in step S20, it is determined whether or not the device is in the “billing prohibition permitted state”. As described above, whether or not it is in the “charge prohibition permission state” is determined by whether or not the owner of the ETC card 230 is in the vehicle and the ETC card 230 is inserted when the vehicle is started. It depends on what. Here, when it is not in the “billing prohibition permission state” (negative determination), the subsequent processing is not performed. On the other hand, if the “charging prohibition permission state” is set (positive determination), the process proceeds to step S21.

  In step S21, it is determined whether or not a communication line between the BT communication apparatus 210 and the portable terminal 240 has been established. Here, when the communication line is not established (negative determination), the subsequent processing is not performed. For example, what is established for some reason (for example, when the power of the portable terminal 240 is turned off) while the vehicle is running corresponds to a case where the vehicle is disconnected. On the other hand, when BT connection is established (positive determination), the process proceeds to step S22.

  In step S <b> 22, using the BT communication device 210, information indicating that the ETC card 230 has been set in the charge prohibition state is transmitted to the mobile terminal 240.

  In step S23, it is determined whether or not the ETC card 230 has been removed. If it has been removed (affirmative determination), in step S26, information indicating that the charge prohibition state has been released is transmitted to the portable terminal 240. In this case, it is indicated that the owner of the ETC card 230 has the ETC card 230 and is likely to leave the vehicle.

  Note that, based on the information transmitted in step S22 or step S26, the mobile terminal 240 can recognize whether or not the ETC card 230 is in a charge prohibition state. Then, as will be described later, based on this information, the mobile terminal 240 notifies that the ETC card 230 is in a charge prohibition state.

  On the other hand, if the ETC card 230 has not been removed in step S23 (negative determination), the process proceeds to step S25.

  In step S25, it is determined whether or not a predetermined time has elapsed, or whether or not the BT connection with the mobile terminal 240 has been disconnected. Here, when the predetermined time has not yet elapsed or when the BT connection with the portable terminal 240 is established (negative determination), the process returns to step S23 again. If the ETC card 230 is removed in step S23, information indicating that the charge prohibition state has been released is transmitted to the portable terminal 240 in step S26. That is, when the engine of the vehicle is stopped (ACC OFF) and the ETC card 230 is removed within a predetermined time, the subsequent process of placing the ETC card 230 in the charge prohibition state is not performed.

  On the other hand, when the predetermined time has elapsed or the BT connection with the mobile terminal 240 is disconnected (affirmative determination), the ETC card 230 is set in a charge prohibition state in step S27. As described above, the charging prohibition state refers to a state in which charging cannot be performed using the ETC card 230. For example, the identification information for identifying information written on the ETC card 230 is rewritten with other information, Make sure you don't know where the information required for payment is written. Further, the information written in the ETC card 230 is transferred to the main body 100 as it is, or the identification information for identifying the ETC card 230 is rewritten so that other ETC on-board devices cannot recognize the ETC card. You may do it.

  Thereby, even when the owner of the ETC card 230 leaves the vehicle with the ETC card 230 inserted, it is possible to prevent others from being charged using the ETC card 230. The reason that the ETC card 230 is forcibly prohibited when the predetermined time has elapsed is that the power consumption of the battery is suppressed because the engine is stopped. In addition, it is not conceivable that the owner of the ETC card 230 leaves the mobile terminal 240 while leaving the mobile terminal 240 on the vehicle. In this case, however, the ETC card 230 is forcibly forced after a predetermined time. Is in a charge-prohibited state, so there is no problem.

  Thereafter, in step S28, the BT communication apparatus 210 is shifted to a standby state. This standby state refers to a state in which a signal requesting BT connection, which is transmitted from a terminal side having a BT communication device, can be received. At this time, if the mobile terminal 240 is BT-connected, the mobile terminal 240 is disconnected. In this state, the BT communication device 210 transmits a predetermined signal to the surrounding area and does not detect a terminal having a BT communication apparatus existing in the surrounding area.

  In conjunction with the getting-off process performed by the main body 100 described above, the mobile terminal 240 performs the charge prohibition state notification process. Specifically, the processing is performed according to the flowchart of FIG.

  First, in step S30, it is determined whether or not information indicating that the ETC card 230 is in a charge prohibition state has been received from the main body 100. Here, when this information is not received (negative determination), the subsequent processing is not performed. That is, in this case, the owner does not leave the vehicle with the ETC card 230 inserted. On the other hand, when the information indicating that the ETC card 230 is in the charge prohibition state is received (positive determination), the process proceeds to step S31.

  In step S31, it is determined whether or not information indicating that the charge prohibition state of the ETC card 230 has been released is received from the main body 100. Here, when this information is received (positive determination), the subsequent processing is not performed. That is, in this case, the owner of the ETC card 230 possesses the ETC card 230 and leaves the vehicle. On the other hand, when the information indicating that the charge prohibition state of the ETC card 230 has been released has not been received (No determination), the process proceeds to step S32.

  In step S32, it is determined whether or not a predetermined time has elapsed, or whether or not the BT connection with the BT communication apparatus 210 has been disconnected. This is a process corresponding to step S25 performed by the main body 100 described above. Therefore, the predetermined time of this step and the predetermined time of step S25 are the same time. Here, when the predetermined time has not yet elapsed or when the BT connection with the BT communication apparatus 210 is established (negative determination), the process returns to step S31 again. In step S31, when information indicating that the charge prohibition state of the ETC card 230 has been released is received from the main body 100, the subsequent processing is not performed. That is, in this case, the owner of the ETC card 230 stops the engine of the vehicle and removes the ETC card 230 within a predetermined time.

  On the other hand, when the predetermined time has elapsed or the BT connection with the BT communication apparatus 210 is disconnected (affirmative determination), in step S33, the display unit 241 indicates that the ETC card 230 is in a charge prohibition state. indicate. That is, in this case, the main body 100 puts the ETC card 230 in the charge prohibition state in step S27. As a result, the owner of the ETC card 230 can recognize that the ETC card 230 is still inserted, and the other person will not be charged with the ETC card 230. I can.

  In step S <b> 33, the owner who has been notified that the ETC card 230 is in a charge-prohibited state is expected to return to the vehicle again in order to remove the ETC card 230. In this case, since the ETC card 230 is in a charge prohibition state, it is necessary to cancel it. The processes at this time are “500: charge prohibition state release process (mobile terminal side)” and “600: charge prohibition state release process (main body side)” shown in the sequence diagram of FIG. Specifically, the portable terminal 240 performs processing according to the flowchart of FIG. 6, and the main body 100 performs processing according to the flowchart of FIG. Hereinafter, this process will be described.

  First, in step S40, the portable terminal 240 transmits a signal requesting cancellation of the charge prohibition state to the BT communication apparatus 210. This is done by providing a switch for transmitting the signal to the portable terminal 240 and operating the switch by the owner of the ETC card 230.

  When the BT communication apparatus 210 receives a signal requesting cancellation of the charging prohibition state, the BT communication apparatus 210 performs an authentication process for BT connection with the mobile terminal 240. If the BT connection is established through this authentication process, the BT communication apparatus 210 transmits a signal indicating that to the portable terminal 240 (step S50). And the portable terminal 240 receives this signal (step S41). Thereafter, the arithmetic processing unit 110 cancels the charge prohibition state of the ETC card 230 that is in the charge prohibition state (step S51). Specifically, for example, when the identification information of the information written in the ETC card 230 is changed, the original identification information is restored.

  Then, information indicating that the release has been performed is transmitted to the mobile terminal 240 (step S52), and the mobile terminal 240 displays the release on the display unit 241 (step S42). As a result, the owner of the ETC card 230 can recognize that the charge prohibition state of the ETC card 230 has been cancelled, and thus the ETC card 230 is pulled out and possessed.

  In addition, the charge prohibition state may be canceled by turning on the accessory switch of the vehicle and performing the above-described startup process (see FIG. 3).

  In addition, when the charge prohibition state of the ETC card 230 is released through the processing of FIGS. 6 and 7, the owner leaves the vehicle without removing the ETC card 230. 4), the ETC card 230 is again set in the charge prohibition state.

  As described above, when the ETC on-board device 10 according to the present embodiment determines that the owner of the ETC card 230 has left the vehicle while the ETC card 230 is inserted, the ETC card 230 cannot be charged by the ETC card 230. As a result, even if the ETC card 230 is stolen, damage can be minimized. Further, when the owner of the ETC card 230 leaves the vehicle, there is no need to remove the ETC card 230. That is, the troublesomeness of inserting and removing the ETC card 230 can be eliminated. Further, since the owner of the ETC card 230 is determined whether it is away from the vehicle based on whether the owner is carrying a BT connection with the portable terminal 240 carried by the owner, the owner is particularly aware Therefore, the security of the ETC card 230 can be improved.

(Modification)
In the present embodiment, whether or not the owner of the ETC card 230 has left the vehicle is determined based on whether or not the mobile terminal 240 carried by the owner is BT-connected. This is to improve card security without the owner of the ETC card 230 being particularly conscious.

  However, if the purpose of improving the card security can be achieved, the mobile terminal 240 is not particularly required. For example, the main body 100 is provided with a switch for prohibiting charging of the ETC card 230. When the vehicle engine is stopped and the ETC card 230 is inserted, a notification is made as to whether or not the ETC card 230 is in a charge prohibition state. Then, when the switch for prohibiting charging is pushed by the owner of the ETC card 230 that has received this, the ETC card 230 is set in the charging prohibited state. Further, when the owner of the ETC card 230 returns to the vehicle after that, as a method of canceling the charge prohibition state of the ETC card 230, the owner is required to input a password, which matches the pre-registered password. If so, there is a method to cancel it. However, the operation burden on the owner of the ETC card 230 is slightly increased as compared with the method using the mobile terminal 240.

It is a block diagram which shows the whole structure of the ETC onboard equipment 10 based on this embodiment. It is a figure which shows the communication sequence between each structure part of the ETC onboard equipment 10 when making the ETC card 230 inserted in the card insertion slot into a charge prohibition state, or canceling a charge prohibition state. It is a flowchart which shows the process (startup process) which the arithmetic processing part 110 performs when an ACC switch is turned on.
