[0023]
First, when a user purchases a vehicle at an automobile dealer, an “information disclosure content license” of an in-vehicle electronic license plate 220 to be attached to the purchased automobile is handed over to the user. After entering the name, address, etc. in the “Public Content License”, the vehicle data public license range by the in-vehicle electronic license plate 220 is described and designated in the “Information Public Content License” (FIGS. 5 and 6). S100-190).
[0024]
Specifically, as a public permission range, (1) only the automobile registration number described in the number plate (label plate) 40 is selected, (2) all the information described in the vehicle inspection certificate is selected, (3 ) Individual vehicle determination, that is, vehicle user cannot be specified but only vehicle type data indicating only the vehicle type is selected. (4) No vehicle data is selected. (5) Vehicle data is transmitted to a private company. Or prohibition.
[0025]
Upon completion of the specification of the vehicle data disclosure permission range as described above, the employee of the car dealer can use the optical character reader (OCR) from the “information disclosure content license” to specify the specified range information indicating the disclosure permission range. Read this specified range information and register it in the car information registration center by e-mail (or FAX) together with vehicle length data, vehicle width data, vehicle height data, vehicle type data, vehicle user name data, vehicle user address data It transmits to the management server 400 (S200 in FIG. 7).
[0026]
In this way, when data such as designated range information and vehicle length data is sent from the car dealer to the registration management server 400, the registration management server 400 issues a car registration number. Then, the registration management server 400 stores the data such as the designated range information and the vehicle length data sent from the car dealer as described above together with the car registration number in the database (S210 in FIG. 7).
[0027]
Next, the registration management server 400 transmits each data stored in this database to a management computer (management PC) 410 of a car registration window such as a land transportation branch office.
[0028]
Accordingly, the management computer 410 issues a vehicle inspection certificate using a printer based on the data sent from the registration management server 400. In addition to this, vehicle data within the open permission range designated by the vehicle user as described above is extracted from each data such as designated range information and vehicle length data stored in the database. Further, the extracted vehicle data (hereinafter referred to as user-designated vehicle data) is printed on a part of the vehicle inspection document using a printer as a barcode (for example, a two-dimensional barcode) (S220).
[0029]
Thereafter, the operator of the automobile registration window stores the user-designated vehicle data in the in-vehicle electronic license plate 220 using the management computer 410 as follows.
[0030]
That is, the user-designated vehicle data is read with a barcode from a part of the vehicle inspection document by the optical barcode scanner, and the user-designated vehicle data is stored in the management computer 410 (S230).
[0031]
Thereafter, the operator operates the management computer 410 to transmit an identification data request signal from the data read / write device 420 via radio waves. Accordingly, when the identification data request signal is received by the wireless unit 222 of the in-vehicle electronic number plate 220, the control unit 223 reads the identification data from the memory 224 and causes the wireless unit 224 to transmit the identification data.
[0032]
When such identification data is sent to the management computer 410 via the data read / write device 420, the management computer 410 displays the identification data on the display. Here, when the operator confirms that the displayed identification data matches the identification data printed on the in-vehicle electronic number plate 220 itself, the user-specified vehicle data is stored in the in-vehicle electronic number plate 220. For the purpose.
[0033]
Along with this, the management computer 410 causes the data read / write device 420 to transmit user-specified vehicle data via radio waves. Thereafter, when the user-designated vehicle data is received by the wireless unit 222 of the in-vehicle electronic license plate 220, the control unit 223 stores the user-designated vehicle data in a specific area of the memory 224 (S270).

In addition, when prohibition of transmission of vehicle data to a private company is set, prohibited data indicating that transmission of vehicle data to the private company is prohibited is stored in the specific area.
[0035]
Next, the operation of this embodiment will be described with reference to FIG. The control unit 223 of the in-vehicle electronic license plate 220 executes the computer program according to the flowchart of FIG. This program is repeated at regular intervals while the vehicle is running.
[0036]
First, when the request signal from the roadside device 210 is received by the wireless unit 222 (S300), it is determined whether or not the administrator of the roadside device 210 that transmits the request signal is a private business operator (S310).
[0037]
Here, the request signal includes an identification code indicating the identification of the manager. If it is determined that the manager of the roadside device 210 is a public organization (for example, police) according to the identification code, the memory 224 is used. The user-specified vehicle data is called from the specific area and transmitted from the radio unit 222 (S330, S340).
[0038]
In S310, whether or not prohibition of transmission of vehicle data to the private business operator is set when the administrator of the roadside device 210 determines that it is a private business operator according to the identification code included in the request signal. Is determined (S320).
[0039]
Here, when the above-mentioned prohibited data is stored in the specific area of the memory 224, it is determined that the prohibition of transmission of the vehicle data to the private business is set, and the user-specified vehicle by the wireless unit 222 is determined. Do not send data. If the above-mentioned prohibited data is not stored in the specific area of the memory 224, it is determined that the prohibition of transmission of the vehicle data to the private company is not set, and the user designation is made from the specific area of the memory 224. The vehicle data is called and transmitted from the wireless unit 222 (S330, S340).
[0040]
Next, the effect of this embodiment is demonstrated. That is, in the in-vehicle electronic license plate 220 for transmitting vehicle data to the road unit 120 via radio waves, only the vehicle registration number of the vehicle is transmitted as vehicle data, or the vehicle data is transmitted as vehicle data. Only the vehicle type identification data is transmitted, no data is transmitted as vehicle data, or the vehicle data indicated in the vehicle inspection document is transmitted. Moreover, it can be set not to transmit vehicle data to a road operator of a private business operator according to the user's request.
[0041]
As described above, the vehicle-mounted electronic license plate 220 transmits only the vehicle data designated in advance by the vehicle user from the wireless unit 222, and thus privacy can be protected by the designation of the vehicle user.
