Description

  The present invention relates to a multi-purpose ETC on-board device and a multi-purpose toll payment system, not only for toll payment on toll roads, but also for toll road toll gates such as convenience stores, parking lots, drive-through stores, and gas stations while passengers are in the car. The fee can be settled at other fee payment locations.

  In the toll road, a wireless automatic toll collection system (ETC: Electronic Toll Collection System) has been introduced for the purpose of reducing traffic congestion at the toll gate. In this ETC, an ETC vehicle-mounted device is mounted on a vehicle, and an ETC card (IC card) is inserted into the ETC vehicle-mounted device, thereby performing bidirectional wireless communication with the roadside antenna of the toll gate on the toll road. Make a payment. For this reason, it can pass through a toll gate almost non-stop.

  Note that bidirectional wireless communication with the roadside antenna is performed by dedicated short range communication (DSRC). As the ETC card, a contact type IC card, that is, an IC card of a type having a contact terminal and transmitting / receiving signals by contacting the contact terminal with the vehicle-mounted device side terminal is used.

  The vehicle identification information (registration number, model, etc.) of the vehicle equipped with this ETC vehicle-mounted device is written on the ETC vehicle-mounted device, and personal information (name, credit card number, etc.) is recorded on the ETC card. ing.

  The ETC on-board unit is equipped with an encryption module called SAM (Security Access Module) that encrypts communication data. When the ETC card is mounted on the ETC on-board unit, the ETC card and the ETC are transmitted by encrypted data communication. Mutual authentication is performed with the vehicle-mounted device, and it is authenticated whether or not the attached card is an ETC card. In other words, if the encryption key matches and data communication is possible, it means that authentication has been performed, and if the encryption key does not match and data communication cannot be performed, it means that authentication cannot be performed. For this reason, the cryptographic module (SAM) also has a function of performing card authentication by communicating with the IC card.

  By the way, since the ETC card is a dedicated card that can be used only for payment of charges in the ETC, its use is limited to toll road charging.

  On the other hand, a non-contact type IC card that enables multi-purpose payments has been put into practical use. With this non-contact type IC card, it is now possible to make fee payments at a drive-through store or the like. In order to make a payment with such a non-contact type IC card, the non-contact type IC card is placed over the fee payment place side antenna installed at the charge payment place such as a drive-through store, It is necessary to perform wireless communication with the contact type IC card.

  Thus, in the fee settlement using the non-contact type IC card, it is necessary to hold the non-contact type IC card over the fee payment place side antenna (that is, contact or approach). For this reason, even if an occupant of an automobile equipped with an ETC on-vehicle device has a non-contact type IC card, it is necessary to hold the non-contact type IC card over the toll payment place side antenna.

  Insert a non-contact type IC card for multi-purpose settlement into the ETC OBE and use the communication function of the ETC OBE to connect to the fare payment location antenna installed at the fare payment location such as a drive-through store. It would be convenient if you could settle the fee by wireless communication.

  In order to enable multi-purpose settlement using a non-contact IC card for multi-purpose settlement via the ETC on-board device, it is necessary to mount a circuit configuration for multi-purpose settlement on the ETC on-board device. However, simply mounting the circuit configuration for multi-purpose settlement in the ETC on-board unit has a problem that the ETC on-board unit becomes large and expensive.

  In view of the above prior art, the present invention provides a multipurpose ETC on-board device and a multi-purpose charge settlement system that can perform multi-purpose settlement using a non-contact IC card for multi-purpose settlement and maintain the downsizing of the ETC on-board device. The purpose is to do.

The configuration of the multipurpose ETC OBE of the present invention that solves the above problems is as follows.

A non-contact type IC card driving module that reads the information recorded on the non-contact type IC card by driving the mounted non-contact type IC card;
Communication means for performing two-way wireless communication between information read by the contact IC card encryption module and the non-contact IC card drive module with an external device.

In this case,
The coil antenna provided in the non-contact type IC card driving module is smaller than the coil antenna provided in the non-contact type IC card, and when the non-contact type IC card is mounted on a multipurpose ETC on-vehicle device, It is arranged so as to be close to one side of the coil antenna provided in the contact type IC card,
The non-contact type IC card drive module is composed of a pair of coils arranged at a distance between the non-contact type IC card when the non-contact type IC card is mounted on a multipurpose ETC on-vehicle device. A coil antenna may be provided.

The configuration of the multipurpose fee settlement system of the present invention is as follows.
Any of the multipurpose ETC on-board devices described above;
It consists of a toll device installed at a toll payment location other than the toll road toll gate,
The fee apparatus comprises a communication means for performing bidirectional wireless communication with the multipurpose ETC on-vehicle device,
A cryptographic module for a non-contact type IC card is provided that obtains information recorded in the non-contact type IC card via two-way wireless communication, reads the information, and authenticates the non-contact type IC card. It is characterized by.

  According to the present invention, a non-contact type IC card can be used to pay a fee at a place other than a toll road toll box by simply mounting (inserting) a non-contact type IC card for multi-purpose settlement on an ETC on-board unit. The convenience can be improved.

  Moreover, the non-contact type IC card cryptographic module (SAM) for authenticating the non-contact type IC card is provided not on the ETC on-board unit side but on the toll gate side, so there is no loss of downsizing of the ETC on-board unit, The downsizing of the ETC on-board unit can be maintained.

  The best mode for carrying out the present invention will be described below in detail based on examples.

  FIG. 1 is a block configuration diagram showing an ETC on-vehicle device and a multi-purpose charge settlement system according to Embodiment 1 of the present invention. The first embodiment is an example in which a fee payment place other than a toll road is a parking lot.

  As shown in FIG. 1, the ETC vehicle-mounted device 10 includes a DSRC modulation / demodulation circuit 11, a CPU 12, a contact IC card SAM (encryption module) 13, and a non-contact IC card drive module 14. The antenna 15 is connected. An ETC card 21 that is a contact IC card and a non-contact IC card (for example, Felica (trade name)) 22 for multi-purpose settlement are inserted into the ETC on-board device 10.

  FIG. 2 shows a state in which the ETC card 21 and the non-contact type IC card 22 are inserted into the ETC vehicle-mounted device 10. As shown in FIG. 2, the ETC card 21 and the non-contact type IC card 22 can be inserted (attached) into the insertion slot 10a which is the card attachment structure of the ETC on-vehicle device 10.

  Returning to FIG. 1 and continuing the description, when the ETC card 21 is inserted into the ETC vehicle-mounted device 10, the contact terminal of the ETC card 21 and the contact terminal of the contact IC card SAM 13 are connected, and the ETC card 21 and the contact type are connected. Mutual authentication is performed with the IC card SAM 13 to authenticate whether the inserted card is an ETC card or not. That is, the contact IC card SAM 13 authenticates the inserted ETC card 21 and reads information recorded on the ETC card 21.

  When the non-contact type IC card 22 is inserted into the ETC vehicle-mounted device 10, the coil antenna of the non-contact type IC card 22 and the coil antenna of the non-contact type IC card driving module 14 are close to each other, and the non-contact type is caused by mutual induction action. The IC card 22 is driven. That is, the non-contact type IC card drive module 14 drives the non-contact type IC card 22 and reads information recorded on the non-contact type IC card 22.

  Even if the non-contact type IC card 22 is inserted into the ETC on-board unit 10, the ETC on-board unit 10 does not authenticate the inserted non-contact type IC card 22. Whether the inserted non-contact type IC card 22 is a multi-purpose payment card (for example, Felica) is authenticated on the parking fee apparatus 30 side as will be described later. In this way, the authentication of the non-contact type IC card 22 is not performed on the ETC on-board unit 10 side, but is provided on the side of the fee device (the parking fee device 30 in this example) installed in the fee payment place other than the toll road. This is one of the technical points in this embodiment.

  Note that the constituent members other than the non-contact type IC card drive module 14 in the ETC on-vehicle device 10 are provided in a conventional general ETC on-vehicle device. That is, the ETC in-vehicle device 10 of the present embodiment can acquire information (personal information and card type information) of the non-contact type IC card 22 by adding the non-contact card driving module 14 to the conventional ETC on-vehicle device. It is a thing.

Therefore, when the ETC card 21 and the non-contact type IC card 22 for multi-purpose settlement are inserted into the ETC on-vehicle device 10, the information of the cards 21 and 22 is externally transmitted by the DSRC via the CPU 12, the DSRC modulation / demodulation circuit 11 and the antenna 15. Bi-directional wireless communication is carried out with the above-mentioned devices (the roadside equipment of the toll road toll gate or the parking lot fee device 30).
That is, the ETC in-vehicle device 10 uses the CPU 12 and the DSRC modulation / demodulation circuit 11 as communication means for wirelessly communicating information read by the contact type IC card SAM 13 and the non-contact type IC card drive module 14 with external devices. And an antenna 15.

  On the other hand, the parking fee apparatus 30 includes a DSRC digital unit 31, a parking lot processing unit 32, a control unit 33, a vehicle detector 34, a bar controller 35, and a non-contact IC card SAM 36. ing. The DSRC digital unit 31 is connected to the DSRC radio unit 37 and the antenna 38, the bar controller 35 controls the lifting and lowering of the bar 39, and the non-contact IC card SAM 36 is connected to the settlement center 40. .

  The parking fee apparatus 30 includes communication means (DSRC digital unit 31, DSRC radio unit 37, antenna 38) for performing bidirectional wireless communication with the ETC on-vehicle device 10, and a non-contact IC card SAM 36. It is different from a normal parking fee device.

  In the parking fee apparatus 30, the vehicle detector 34 detects the approach of the vehicle, and the control unit 33 and the bar controller 35 control the ascending / descending of the bar 39 so that the vehicle can enter or leave the parking lot. Perform admission control. And the parking lot process part 32 calculates the parking fee according to parking time.

  Next, the operation of the multi-purpose fee settlement system including the above-described ETC on-board device 10 and the parking fee device 30 as components will be described.

  When a vehicle equipped with the ETC on-board device 10 approaches the roadside antenna of the toll road toll gate, two-way wireless communication is performed between the ETC onboard device 10 and the roadside antenna, and the individual written in the ETC card 21 Information etc. are transmitted.

  In addition, when a vehicle equipped with the ETC on-board device 10 approaches the parking lot fee device 30 for parking, bidirectional wireless communication is performed between the ETC on-vehicle device 10 and the parking lot fee device 30, and a non-contact type. Personal information and card type information written in the IC card 22 is transmitted.

For this reason, in the non-contact IC card SAM 36 built in the parking fee apparatus 30, the transmitted card type information of the non-contact IC card 22 is read, and the inserted card is a card for multi-purpose settlement. Whether or not can be authenticated.
Further, the non-contact type IC card SAM 36 acquires the personal information written in the non-contact type IC card 22, adds the personal information to the parking fee data corresponding to the parking time, and transmits it to the settlement center 40 for parking. Charge settlement processing.

As described above, in the first embodiment, the parking fee can be settled by inserting the non-contact type IC card 22 for multi-purpose settlement into the ETC in-vehicle device 10. That is, the parking fee can be settled without the non-contact type IC card 22 being held over the antenna of the parking lot fee device, which is convenient.
As described above, in the first embodiment, the payment method for a credit card type non-contact type IC card in which personal information is recorded on the card has been described. However, the deposit type non-contact type IC card can also be processed.

  Further, in the first embodiment, the non-contact type IC card SAM 36 that performs the authentication operation of the non-contact type IC card 22 is provided on the parking lot fee device 30 side without being mounted on the ETC on-board unit 10 side. Therefore, the ETC in-vehicle device 10 does not need to be provided with a non-contact IC card SAM for authentication, and can be downsized accordingly.

  In addition, in a drive-through store or a gas station, a charge device equipped with a communication function capable of communicating with an ETC on-board device and a non-contact IC card SAM for authenticating a multi-purpose payment non-contact IC card is provided. As a result, it becomes possible to perform fee settlement without holding the non-contact type IC card over the antenna of the fee device.

  The second embodiment relates to a planar antenna of the non-contact type IC card driving module 14 provided in the ETC on-vehicle device 10.

  As shown in FIG. 3, the non-contact type IC card 22 has a planar antenna coil 22a that circulates along the periphery of the card. In this manner, the planar antenna coil 22a is arranged so as to circulate along the periphery of the card, which is defined as a standard for IC cards.

On the other hand, the non-contact type IC card drive module 14 has a coil antenna (excitation coil) 14a, an analog circuit 14b, and a digital circuit 14c as shown in FIG. The coil antenna 14 a is smaller than the planar antenna coil 22 a of the non-contact type IC card 22.
In addition, when the non-contact type IC card 22 is inserted into the ETC vehicle-mounted device 10, as shown in FIG. 5, the coil antenna 14a is arranged so that the coil antenna 14a is close to (or overlaps) one side of the coil antenna 22a. The position is set.

Although the coil antenna 14a of the non-contact type IC card drive module 14 is small, since it is close to one side of the coil antenna 22a of the non-contact type IC card 22, the mutual inductance between both the coils 14a and 22a is improved and good. Communication and excitation operations can be performed.
Incidentally, if the center of the small coil antenna 14a is aligned with the center of the coil antenna 22a (when the antennas 14a and 22a are concentrically arranged), the mutual inductance between the coils 14a and 22a becomes small. Bad condition.

  Thus, since the coil antenna 14a can be reduced, the non-contact type IC card drive module 14 is also reduced. Even if the non-contact type IC card drive module 14 is provided in the ETC on-board unit 10, the overall size of the on-board unit is maintained. can do. Further, by arranging the coil antenna 14a at the position as described above, good communication and excitation operation can be ensured.

  In the third embodiment, the arrangement position of the coil antenna 14a of the non-contact type IC card driving module 14 is separated into two. That is, as shown in FIG. 6, with the non-contact type IC card 22 inserted in the ETC vehicle-mounted device 10 interposed therebetween, the arrangement position of the coil antenna 14a is set to the upper coil 14a-1 and the lower coil 14a--. 2 is separated. Thus, the mutual inductance can be improved by sandwiching the coil antenna 22a between the pair of coils 14a-1 and 14a-2. As a result, the coil antenna 14a on the transmission side (consisting of the coils 14a-1 and 14b-1) can be obtained. Antenna) can be made small, and the non-contact type IC card drive module 14 can be made small.

  The present invention can be used not only for fee payment at a toll road fee payment place, but also for multi-purpose payment via an on-vehicle device at a convenience store, a parking lot, a drive-through store, a gas station, or the like.
