Abstract

A vehicle authentication control device has a first, second, and third determination units, and a registration unit. When identification information unique to a vehicle is registered in both a portable device and an authentication device on the vehicle, the first determination unit matches first identification information returned from the portable device in response to a request from the authentication device and second identification information registered in the authentication device to determine whether a combination of the portable device and the authentication device is legitimate. When third identification information is registered in a part different from the authentication device, the part performing a predetermined operation when the first determination unit is legitimate, the second determination unit matches the third identification information registered in the part and the second identification information registered in the authentication device to determine whether a combination of the part and the authentication device is legitimate. The second determination unit determines that the part is a non-used article if the third identification information is not registered in the part. If the determination results of the first determination unit and the second determination unit are both positive, then the third determination unit determines that a combination of the part, the portable device, and the authentication device is legitimate. If the second determination unit determines that the part is a non-used vehicle, the registration unit registers the second identification information registered in the authentication device as third identification information.

Claims

1. A vehicle authentication control device comprising:

a first determination unit;

a second determination unit;

a third determination unit; and

a registration unit;

wherein, when identification information unique to a vehicle is registered in both a portable device and an authentication device on the vehicle, the first determination unit matches first identification information returned from the portable device in response to a request from the authentication device and second identification information registered in the authentication device to determine whether a combination of the portable device and the authentication device is legitimate,

wherein, when third identification information is registered in a part different from the authentication device, the part performing a predetermined operation when the first determination unit is legitimate, the second determination unit matches the third identification information registered in the part and the second identification information registered in the authentication device to determine whether a combination of the part and the authentication device is legitimate,

wherein the second determination unit determines that the part is a non-used article if the third identification information is not registered in the part;

wherein, if the determination results of the first determination unit and the second determination unit are both positive, then the third determination unit determines that a combination of the part, the portable device, and the authentication device is legitimate, and

wherein, if the second determination unit determines that the part is a non-used vehicle, the registration unit registers the second identification information registered in the authentication device as third identification information.

2. The vehicle authentication control device according to claim 1, wherein the part returns specific information indicating to be a non-used article instead of the third identification information when the part is a non-used article.

3. The vehicle authentication control device according to claim 1, wherein the part is a steering lock unit.

4. The vehicle authentication control device according to claim 2, wherein the part is a steering lock unit.
