Description of the Related Art In recent years, as one of the toll collection methods on toll roads, an automatic toll which completes toll collection by wireless communication between an interrogator installed on a toll gate and a transponder installed on a vehicle side. Receiving system (ETC: Electronic Tol)
l Collection) is being studied.

[0003] The automatic toll collection system is a wireless communication between a central processing unit (hereinafter referred to as a roadside unit) installed at a tollgate and an automatic toll collection unit (hereinafter referred to as an onboard unit) installed on a vehicle. This acts as a proxy for toll collection at tollgates. The roadside unit performs wireless transmission to the onboard unit, and the onboard unit transmits information on the vehicle side (vehicle type information, entrance tollgate information, check barrier information, etc.) according to the received content.
Is transmitted to the roadside device, the roadside device performs a charge calculation process in accordance with the information, transmits a result such as a charge notification to the vehicle-mounted device, and the vehicle-mounted device writes the received price information on a recording medium such as an IC card. To debit or pay later.

[0004] Toll roads in Japan have various toll forms depending on the type of vehicle. Therefore, the vehicle-mounted device needs to transmit “vehicle type information” to the roadside device. For this reason, the vehicle-mounted device needs to hold "vehicle type information" therein, and the vehicle-mounted device needs to be a device for each vehicle or for each vehicle type. However, if a malicious person removes the on-board unit installed on a small car and re-installs it on a large car and uses it, it can pass through a toll road at the price of a small car despite being a large car There is a possibility. For that purpose, you can replace the onboard device with another vehicle,
Several methods have been devised to make the removal itself impossible. For example, in Japanese Patent Application Laid-Open No. 9-62881, a seal for sealing is attached between an in-vehicle device and an in-vehicle device mounting portion of a vehicle. A method that leaves evidence of that, or an optical sensor is placed on the vehicle-mounted device mounting part of the vehicle, usually this optical sensor is covered by the vehicle-mounted device, and when the vehicle-mounted device is removed, external light is detected by the light sensor Accordingly, a method of detecting the removal, a method of detecting the removal by removing the spring installed on the back surface of the vehicle-mounted device when the device is removed, and the like are described. Then, when removal is detected, the on-board unit is replaced with a vehicle of another vehicle type, and transmission to the roadside device is prohibited or vehicle type information is deleted so that unauthorized use is not possible. ing.

[0005]

However, in the conventional method as described above, when the vehicle-mounted device is mounted on a vehicle, the vehicle-mounted device may be removed due to poor mounting or erroneous mounting.
Even if the device is detached due to insecure attachment, the vehicle-mounted device cannot be used, and there is a problem that another new vehicle-mounted device must be prepared.

SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned conventional problems, and it is an object of the present invention to provide an on-vehicle device for road-to-vehicle communication which prevents unauthorized relocation of the on-vehicle device and permits non-illegal relocation. The purpose is to provide.

[0007]

According to the present invention, in order to achieve the above object, when the on-vehicle device is detached, the on-vehicle device is usable instead of being disabled. The vehicle type information is automatically changed to a vehicle type having a higher price than the vehicle type set in the above, so that the unauthorized user can recognize that the cost is not paid even if the unauthorized use is performed. In addition, discrimination is made between transfers for unauthorized use and non-illegal use, and in the case of non-illegal use, the on-board unit is used continuously without changing to a higher-priced vehicle model. It is made possible.

Let it be 1. Next, in step S13, the comparison determination means 14 determines whether or not the vehicle is to be mounted on another vehicle. This is also the same process as in the first embodiment. The determination result is stored in the removal history storage unit 16 together with the removal date and time, the number of times, and the like.
If the comparison determining means 14 determines that the vehicle is to be mounted on another vehicle, the mounting determination means 17 determines whether or not the number of removals is equal to or greater than the reference number N in step S14. If the number of removals is N or more, step S15
Then, the vehicle type information changing means 5 changes the vehicle type information initially set in the vehicle-mounted device 10 to vehicle type information having a higher fee, preferably the highest vehicle type information. If it is determined in step S13 that the vehicle is not to be mounted on another vehicle, that is, if the vehicle is to be reinstalled in the own vehicle, the process returns to step S11. Therefore, the value of the removal counter increases each time the vehicle is removed, but only when the vehicle is replaced with another vehicle, the number of removals is considered to be a problem in step S14. In the second embodiment, when N is one or more, , Vehicle type information is changed. Then, in step S16, the removal date and time, the number of times, and the like stored in the removal history storage means 16 up to the point of changing the vehicle type information are displayed on the removal history display means 18. As a result, even if the on-vehicle device 10 is mounted on another vehicle, a higher fee is charged when the automatic toll collection system is applied, and the contents are displayed on the display means 18. Therefore, unauthorized use can be prevented.

In the second embodiment, the removal history storage means 16 is arranged after the replacement determination means 17, and the determination result of the replacement determination means 17 is stored at the same time and displayed on the display means 18. You may do so. In this case, for example, the determination flag is set to “1” in the case of replacement with another vehicle, and is set to “0” in the case of reinstallation in the own vehicle. In addition, the contents of the storage means 16 may be displayed on the screen by the display means 18 or a separate warning display may be made by voice, or a printer may be connected so that the stored contents can be printed out on paper and output. Good.

As described above, according to the second embodiment, when the vehicle-mounted device is reinstalled on the own vehicle, the vehicle type information is not changed regardless of how many times the vehicle-mounted device is removed. can do. On the other hand, in the case of remounting to another vehicle, the vehicle type information is changed even by one removal, so that unauthorized use can be prevented.

In each of the above embodiments, an optical sensor including a light emitting element and a light receiving element is used as the detachment detecting means 1. However, other sensors, mechanical switches, and proximities cooperating between the vehicle-mounted device and the vehicle are used. A switch, a reed switch, or the like may be used. Further, a difference in an attachment structure such as fixing, fitting, and locking with a screw may be detected.

Further, in the above-described embodiment, an example is shown in which the comparison determination means 4 and 14 are provided in the removal detection means 1 and 11, but this is because each function is expressed as means in the present invention. It is for convenience and is not intended to limit the device configuration in this way. In an actual device configuration, the CPU performs comparison and determination according to a program based on a signal from a sensor or a switch that detects removal, and when removal is determined, the CPU similarly changes the vehicle type information according to the program. is there.

[0025]

As described above, according to the present invention, when the vehicle-mounted device is detached, the vehicle-mounted device is not disabled, but is switched to a vehicle having a higher fee than the vehicle type set in the vehicle-mounted device. Since the vehicle type information is automatically changed, a warning is displayed on the vehicle-mounted device, so that unauthorized users can be notified that even if they are used illegally, it will not be possible to pay. Use can be prevented beforehand. In addition, discrimination is made between transposition for unauthorized use and non-illegal use, and in the case of non-illegal use,
