Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an automatic toll collection system (hereinafter, referred to as an ETC system) for collecting non-stop tolls from passing vehicles at toll gates of toll facilities such as toll roads and toll parking lots. In particular, the present invention relates to a process when the vehicle information acquired from the on-vehicle device differs from the vehicle information acquired from the electronic license plate when charging at the exit tollgate.
[0002]
[Prior art]
In recent years, in order to eliminate traffic congestion at exit toll booths of toll facilities such as toll roads and toll parking lots, toll billing processing is automatically performed simply by passing vehicles through exit gates at non-stop gates. ETC systems are becoming popular.
[0003]
In such an ETC system, a vehicle number, vehicle type information, entrance information (entrance tollgate name, date and time of passage, etc.) of a passing vehicle are acquired wirelessly from an on-board ETC device in order to automatically determine a fee according to a vehicle type. I do. At the same time, a vehicle type discriminating device is installed at an exit tollgate to detect a vehicle type of a passing vehicle in order to detect unauthorized use of the ETC on-board unit by reloading or the like. Conventionally, this vehicle type determination is performed by a method such as detection of appearance such as vehicle height, vehicle length, vehicle weight, and number of wheels, and reading a license plate by a CCD camera. However, it is not possible to discriminate vehicles having the same appearance but different toll categories, such as a private car and a commercial vehicle, and a sightseeing bus and a route bus, by discriminating only the appearance. Further, in optical number plate reading, a reading error may occur due to dirt on the number plate or the like.
[0004]
As a method of solving the difficulty of such vehicle type discrimination, a method of wirelessly acquiring and using vehicle type information stored in an electronic license plate, which is being put to practical use, has been proposed (for example, Patent Reference 1). Information unique to the vehicle (vehicle number, vehicle type, owner, etc.) is irrevocably stored in the ID tag attached to the electronic license plate, and the vehicle type is reliably identified by reading the information wirelessly. be able to. Therefore, if the vehicle information obtained from the electronic license plate is compared with the vehicle information obtained from the ETC on-board unit and the vehicle type is different, there is a suspicion of unauthorized traffic due to replacement of the ETC on-board unit or the like. It tries to prevent illegal traffic by closing the open / close gate or guiding to the manned gate.
[0005]
By the way, an ETC on-vehicle device is used by inserting an IC card in which personal information such as a fee payment account and balance information is recorded, but it is not enough for a user to purchase an ETC on-vehicle device and simply attach it to a vehicle. , ETC on-board equipment cannot be used. A user who has newly purchased an ETC on-vehicle device specifies an installed vehicle, signs a usage contract with the ETC operator, and registers information specified by the ETC operator on the ETC on-vehicle device unless the ETC onboard device is registered. In-vehicle equipment cannot be used. The conclusion of such a usage contract and the registration of information in the ETC on-board device are performed by a company entrusted by an ETC operator or the like.
[0006]
In this case, the information registered in the ETC in-vehicle device includes the ID of the in-vehicle device, the vehicle number where the in-vehicle device is installed, vehicle type information, and the like. Therefore, the purchased ETC in-vehicle device can be used only with the vehicle and the vehicle type of the vehicle number contracted with the ETC operator, and when installed and used in another vehicle, it is a breach of the contract.
[0007]
However, such information registration to the ETC on-vehicle device is not limited to the case where the ETC on-vehicle device is newly purchased, and there are surprising users who do not know that it is necessary in the following cases. That is,
(1) When replacing a new vehicle with a new vehicle
(2) When changing the license plate
(3) When the vehicle is modified to a towable structure
It is.
[0008]
If the user does not know such a situation, that is, if he / she tries to pass through the exit gate of the ETC system without updating the registration information without malicious intention, the vehicle type information obtained from the registration information of the vehicle-mounted device and the electronic Since the vehicle type information obtained from the license plate is different from the license plate, according to the above-described method, it is determined that the ETC vehicle-mounted device is illegally used, and the exit gate is closed. When such a situation occurs, the following vehicle is also forced to stop, so that non-stop will hinder the operation of the ETC system for sale.

[0021]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram conceptually illustrating a configuration of devices installed near an exit tollgate of the ETC system according to the present embodiment, FIG. 2 is a diagram illustrating a configuration of an exit tollgate terminal device, and FIG. FIG. 4 is a diagram showing a configuration of an on-board ETC device, FIG. 5 is a diagram showing a configuration of an IC card, and FIG. 6 is a flowchart showing a processing flow of an exit tollgate terminal device.
[0022]
As shown in FIG. 1, the ETC system according to the present embodiment assumes a vehicle equipped with both an on-board ETC device 2 and an electronic license plate 3 as a vehicle 1 using a toll facility. Near the exit of the exit tollgate, an ETC communication device 5 provided with an antenna 4 for wireless communication with the on-board ETC device 2 and an electronic license plate communication device 7 provided with an antenna 6 for wireless communication with the electronic license plate 3 , An exit gate opening / closing device 8, a roadside display 9, a vehicle detector 10, and an exit tollgate terminal device 11 are installed.
[0023]
Near the entrance of the entrance tollgate, the same equipment as that of FIG. 1 is installed, though not shown. However, an entrance tollgate terminal device is installed in place of the exit tollgate terminal device. Further, an ETC central device (not shown) is installed in the business company that operates the ETC system. The exit tollgate terminal device and the entrance tollgate terminal device are connected to the ETC central device by a communication line, and necessary information is provided. Give and receive.
[0024]
The electronic license plate 3 is an electronic license plate in which an ID tag is attached to a blank portion of a registration number display portion of a license plate such as a current metal material, and is attached to the front and rear portions of the vehicle. As shown in FIG. 3, the ID tag 5a includes a CPU 5b, a memory 5c, a communication circuit 5d, and an antenna 5e. The memory 5c is composed of a RAM and a ROM. In the ROM, vehicle-specific information required by the external infrastructure, such as a vehicle owner, a vehicle number, a vehicle type, an external size, and a displacement is written in a non-rewritable manner. I have.
[0025]
When the electronic license plate communication device 7 installed on the roadside transmits a polling signal via the attached antenna 6, the ID tag 5a that has received the polling signal reads the vehicle-specific information including the vehicle type information from the ROM in the memory 5c, The signal is transmitted as a response signal via the communication circuit 5d and the antenna 5e. Since the communication area of the electronic license plate communication device 7 is set within a narrow range of several meters from the antenna 6, only the vehicle that has entered the range returns a response signal.
[0026]
The ID tag 5a has a structure in which once it is attached to a license plate and then removed, the information written in the ROM becomes unreadable or is destroyed. Therefore, as long as the electronic license plate 3 is not improperly replaced, the electronic license plate communication device 7 receives the response signal, and thereby accurately converts the vehicle-specific information including the vehicle type information of the vehicle that has entered the communication area. I can figure it out.
[0027]
As shown in FIG. 4, the ETC on-board unit 2 is inserted into a CPU 2a, a memory 2b, an operation unit 2c operated by a user, a display unit 2d for displaying information, a communication circuit 2f having an antenna 2e, and a card slot. An IC card interface unit 2g for interfacing with the IC card 12 is provided. The memory 2b includes an ETC on-board unit number for identifying the ETC on-board unit 2 from other ETC on-board units, a vehicle number for installing the ETC on-board unit 2, vehicle type information, vehicle length, vehicle height, and vehicle-specific information. Are registered as non-rewritable prior to the start of use of the on-board ETC device 2.
[0028]
As shown in FIG. 5, the IC card 12 includes a CPU 12a, a memory 12b, and an interface unit 12c for interfacing with the IC card interface unit 2g of the on-board ETC device 2. The memory 12b is usually configured by a flash memory which is a nonvolatile memory in which information can be electrically rewritten. The IC card 12 is issued by a credit company or the like, and the user name, the bank account number of the user, the expiration date, and the like are recorded in the memory 12b in advance.
[0029]
When the vehicle 1 passes through the entrance tollgate, the entrance information such as the entrance tollgate number and the passage date and time is transmitted from the terminal of the entrance tollgate via the ETC communication device and the antenna to the ETC on-board unit 2 of the vehicle 1. Is done. The ETC on-board unit 2 of the vehicle 1 receives the transmitted entrance information by the antenna 2e and the communication circuit 2f, and writes the information into the memory 12b of the IC card 12 via the IC card interface unit 2g.
[0030]
Conversely, when the vehicle 1 passes through the exit tollgate, an ETC communication device 5 installed near the exit gate opening / closing device 8 sends a polling signal to the ETC on-board unit 2 of the vehicle 1 via the attached antenna 4. Send The on-board ETC unit 2 of the vehicle 1 receives the polling signal via the antenna 2e and the communication circuit 2f, and the vehicle-specific information including the entrance information stored in the IC card 12 and the vehicle type information registered in the on-board ETC unit 2. Is transmitted via the communication circuit 2f and the antenna 2e. The transmitted information is received by the ETC communication device 5 via the antenna 4 and sent to the exit tollgate terminal device 11.
[0031]
The exit gate opening / closing device 8 opens and closes the exit gate of the lane through which the vehicle 1 passes according to an instruction from the exit tollgate terminal device 11. The roadside display 9 displays information to be transmitted to the driver of the vehicle 1 in accordance with an instruction from the exit tollgate terminal device 11. The vehicle detector 10 detects a vehicle approaching the exit gate opening / closing device 8.
[0032]
Next, the configuration of the exit tollgate terminal device 11 will be described with reference to FIG. The exit tollgate terminal device 11 includes a CPU 11a, a memory 11b, a display unit (display) 11c, an operation unit 11d, an interface unit 11e, and a network interface unit 11f. The interface unit 11e is a unit that controls an interface between various devices installed on the roadside and the CPU 11a. The devices installed on the roadside include an ETC communication device 5, an electronic license plate communication device 7, an exit gate opening / closing device 8, a roadside display 9, a vehicle detector 10, and the like. The network interface unit 11f manages an interface between the exit tollgate terminal device 11 and the ETC central device.
[0033]
Next, the processing contents of the exit tollgate terminal device 11 having such a configuration will be described with reference to the flowchart shown in FIG. The vehicle detector 10 installed on the road side before the exit gate opening and closing device 8 and detecting the approach of the vehicle continuously monitors the approach of the vehicle (step S1).
[0034]
When the vehicle 1 is detected, the exit tollgate terminal device 11 instructs the electronic license plate communication device 7 to read the information of the detected electronic license plate 3 of the vehicle 1 and receives the electronic license plate communication. The device 7 sends a request for transmission of vehicle-specific information including vehicle type information to the electronic license plate 3 (step S2). When the electronic license plate 3 receiving the instruction returns the vehicle-specific information, the electronic license plate communication device 7 receives it and sends it to the exit tollgate terminal device 11.
[0035]
The sent information is stored in the memory 11b (Step S3).
[0036]
Subsequently, the exit tollgate terminal device 11 also instructs the ETC communication device 5 to acquire information on the detected ETC on-vehicle device 2 of the vehicle 1. A request to transmit the information registered in the ETC on-board unit 2 and the information recorded in the IC card 12 is transmitted (step S4). When the in-vehicle ETC device 2 that has received the instruction returns the registration information and the record information of the IC card 12, the ETC communication device 5 receives it and sends it to the exit tollgate terminal device 11. The sent information is stored in the memory 11b (Step S5).
[0037]
In the next step S6, a fee is calculated based on the entrance information (entrance tollgate name, passing date and time, etc.) recorded on the IC card 12 and the vehicle type information registered in the ETC on-board unit 2. At this time, it communicates with the ETC central device via the network interface unit 11f as necessary, and acquires information necessary for charge calculation. The fee calculated here is referred to as an ETC vehicle-mounted device reference fee (charge A).
[0038]
In the next step S7, a fee is calculated based on the entrance information recorded on the IC card 12 and the vehicle type information obtained from the electronic license plate 3. The fee calculated here is referred to as an electronic license plate reference fee (charge B).
[0039]
Next, it is checked whether or not the vehicle type information obtained in steps S3 and S5 is the same (step S7a). If the vehicle type information obtained from the electronic license plate 3 matches the vehicle type information obtained from the ETC on-board unit 2, the process proceeds to step S9. If they do not match, the process moves to step S8.
[0040]
Next, a magnitude relationship between the fee A and the fee B calculated in steps S6 and S7 is checked (step S8). Here, in the case of a toll road, the toll is usually determined by the distance between the entrance tollgate and the exit tollgate and the type of vehicle. In the case of a toll parking lot, it is calculated based on the parking time and the vehicle type. That is, the fee generally differs depending on the vehicle type. In this case, the vehicle type is classified by vehicle type, such as ordinary car, large car, mini car, special vehicle, towing car, emergency vehicle such as ambulance, fire truck, sightseeing bus, route bus, physically disabled It also refers to classification by use of vehicles and the like driven by people.
[0041]
If the ETC on-board unit standard charge (charge A) is equal to the electronic license plate reference charge (charge B), the process proceeds to step S9. The fact that the fee A and the fee B are equal means that the vehicle type information acquired from the on-board ETC device 2 and the vehicle type information acquired from the electronic license plate 3 are the same or different vehicle types belonging to the same fee category. I do. Therefore, since there is no problem even if the ETC operator charges the fee and permits the exit from the toll facility, the ETC operator performs the charging process at the calculated fee (step S9). Here, the billing process refers to informing the ETC central device of the calculated fee in association with the unique information of the vehicle 1 and instructing the ETC central device to withdraw the fee from the bank account, or informing the ETC vehicle-mounted device 2 of the fee by radio. . After the charging process is completed, the exit gate opening / closing device 8 is opened (step S13), and the vehicle 1 is exited.
[0042]
If the ETC on-board unit reference fee (charge A) is less than the electronic license plate reference fee (charge B), the process proceeds to step S14. In this case, if the ETC in-vehicle device is charged at the ETC on-board unit reference fee (charge A) and then sent out, the ETC operator may be damaged. Further, in this case, the driver replaces the ETC on-board unit 2 with an ETC on-board unit in which vehicle type information of a low-priced category is registered, or exchanges the electronic license plate 3 with malicious intent. It is also possible. Therefore, in this case, the exit gate opening / closing device 8 is closed without charging, the vehicle 1 is stopped, and a tollgate clerk takes action (step S15).
[0043]
The problem is that the ETC on-board unit standard fee (charge A) is higher than the electronic license plate standard fee (charge B). In the security system of the conventional ETC system, if the vehicle type obtained from the registration information of the on-board ETC device 2 is different from the vehicle type recognized by the vehicle type discriminating apparatus as described in the section of the related art, it is determined that there is a suspicion of fraud. The exit gate opening / closing device 8 was closed to stop the vehicle 1, and a tollgate clerk was taking action. Therefore, even users who have no intention of fraud have to be stopped.
[0044]
On the other hand, in the present embodiment, the vehicle type information obtained from the on-board ETC device 2 is different from the vehicle type information obtained from the electronic license plate 3, so that the ETC on-board device standard fee (charge A) and the electronic license plate Even when the base fee (charge B) is different from the base fee (charge A), if the ETC vehicle-mounted device reference fee (charge A) is higher than the electronic license plate reference fee (charge B), the exit is permitted without stopping. Like that.
[0045]
That is, first, in step S10, the charging process is performed at the ETC vehicle-mounted device reference fee (charge A) in the same manner as in step S9 described above. Subsequently, in step S11, the fact that the vehicle type information registered in the on-board ETC device 2 is different from the vehicle type information recorded in the electronic license plate 3 is displayed on the roadside display 9 to notify the driver.
[0046]
Further, the fact that the vehicle type information is different is transmitted to the ETC in-vehicle device 2 via the ETC communication device 5 to be notified (step S12). The in-vehicle ETC device 2 displays the received content on the display unit 2d to notify the driver that the vehicle type information is different. After such notification, the exit of the vehicle 1 is permitted without closing the exit gate opening / closing device 8.
[0047]
As described above, the reason why the exit is permitted in spite of the difference in the vehicle type information is that the ETC operator is not damaged because the higher fee (the fee A) of the two calculated fees is charged. What can be considered. Therefore, it shall be determined that the user has no intention of committing fraudulent charges. Except for the case where the electronic license plate 3 is exchanged improperly, the vehicle type information registered in the electronic license plate 3 is normally correct, and the vehicle type information registered in the ETC on-board unit 2 is normally What can be considered wrong. And the mistake is that, as explained in the section of the prior art, the registration information of the ETC vehicle-mounted device 2 is
(1) When replacing a new vehicle with a new vehicle
(2) When changing the license plate
(3) When the vehicle is modified to a towable structure
In many cases, the user does not know that it must be updated, and often uses it without updating it, so it is unlikely that the user is performing maliciously.
[0048]
As in the present embodiment, even if the exit is permitted when the vehicle type information is different, if the exit is allowed as it is without being fraudulent as a result, a well-meaning user may be forced to stop unnecessarily. Decrease. Also, the number of cases where the following vehicle is forced to stop unnecessarily is reduced. As a result, the non-stop has the effect that the goodness of the ETC system for sale is further exhibited.
[0049]
In addition, this embodiment may be modified and implemented as follows. That is, the processing order of steps S2 and S3 and steps S4 and S5 in the processing flow of FIG. 6 may be reversed, or parallel processing may be performed.
[0050]
In addition, the electronic license plate communication device 7 and the ETC communication device 5 send an information transmission request in response to the detection of the vehicle 1 by the vehicle detector 10 in step S1, but without installing the vehicle detector 10, Information on the approaching vehicle 1 may be obtained. In that case, the electronic license plate communication device 7 and the ETC communication device 5 continuously transmit polling signals. The electronic license plate 3 and the ETC on-vehicle device 2 that have entered the communication area and received the polling signal return information immediately after receiving the polling signal. Acquire information at the same time. Since the communication area of these communication devices is extremely small, information of only the vehicle 1 approaching the exit gate opening / closing device 8 can be acquired by this method.
[0051]
When the ETC on-board unit standard charge (charge A) and the electronic license plate reference charge (charge B) are equal, only the charging process is performed as it is, but the vehicle type information may be different even if the charge is the same. This is the case where the vehicle types are different but belong to the same fee category. In this case, the driver may be informed of the difference in the vehicle type information in the same manner as in steps S11 and S12 in FIG.
[0052]
Further, when the ETC vehicle-mounted device 2 receives the fact that the vehicle information is different, the vehicle-mounted ETC device 2 may be notified by sound instead of displaying it on the display unit 2d, or may be notified by both display and sound.
[0053]
Further, the above-described embodiment is directed to the processing at the exit tollgate, but these can be applied to the processing at the entrance tollgate with a slight modification. In the case of processing at the entrance tollgate, a gate corresponding to the exit gate opening and closing device 8 in the equipment shown in FIG. 1 is not required. The exit tollgate terminal device 11 is replaced with an entrance tollgate terminal device. The configuration and operation of each of the other devices and the configuration of the entrance tollgate terminal device are the same as those in the above embodiment. In the processing flow of FIG. 6, the processing of the charge calculation becomes unnecessary. Instead, the ETC on-board unit 2 is notified of the entrance information such as the entrance tollgate name and the date and time of passage. The difference in the vehicle type information is determined by directly comparing the information obtained from the on-board ETC device 2 with the information obtained from the electronic license plate 3. If the information is different, the driver uses the same method as in steps S11 and S12. To let them know. In this way, if the driver finds that the vehicle type information is different at the entrance tollgate and informs the driver, the driver uses the manned gate at the exit tollgate instead of passing through the ETC system unmanned gate. You can pay for it. If the driver does so, the vehicle will not be stopped at the unmanned gate of the ETC system, so that the number of vehicles stopped at the unmanned gate can be reduced.
[0054]
The first step described in claim 5 corresponds to steps S4 and S5 in the processing flow of FIG. 6, the second step corresponds to step S6, and the third step corresponds to steps S2 and S3. The fourth step corresponds to step S7.
