Abstract

A vehicle controller is installed in a vehicle and controls one or more operations of the vehicle. The vehicle controller includes a control unit that: (i) outputs a first code for authentication to a judging apparatus which judges whether to permit starting of a driving apparatus of the vehicle when a request for starting the driving apparatus is obtained from an information processor which is located outside the vehicle, (ii) controls locking and unlocking of doors of the vehicle when a request for door lock control is obtained from the information processor, and (iii) obtains from the judging apparatus an authentication result of whether the first code and a second code for authentication which the judging apparatus uses are identical. When obtaining the request for door lock control, the control unit controls the locking and unlocking of the doors based on the authentication result.

Claims

1. A vehicle controller that is installed in a vehicle and that controls one or more operations of the vehicle, the vehicle controller comprising a control unit that:

(i) outputs a first code for authentication to a judging apparatus which judges whether to permit starting of a driving apparatus of the vehicle when a request for starting the driving apparatus is obtained from an information processor which is located outside the vehicle;

(ii) controls locking and unlocking of doors of the vehicle when a request for door lock control is obtained from the information processor; and

(iii) obtains from the judging apparatus an authentication result of whether the first code and a second code for authentication which the judging apparatus uses are identical, wherein

when obtaining the request for door lock control, the control unit controls the locking and unlocking of the doors based on the authentication result.

2. The vehicle controller of claim 1, wherein

when the authentication result indicates that the first code and the second code are not identical, the control unit prohibits execution of the request for door lock control.

3. The vehicle controller of claim 1, further comprising:

a memory that stores the authentication result.

4. A vehicle control system that controls a vehicle, the vehicle control system comprising:

a vehicle controller that is installed in the vehicle, the vehicle controller including a control unit that;

(i) outputs a first code for authentication when a request for starting a driving apparatus of the vehicle is obtained from an information processor which is located outside the vehicle; and

(ii) controls locking and unlocking of doors of the vehicle when a request for door lock control is obtained from the information processor; and

a judging apparatus that receives the first code for authentication from the control unit and judges whether to permit starting of the driving apparatus of the vehicle, and uses a second code for authentication to determine an authentication result of whether the first code and the second code are identical, wherein

when obtaining the request for door lock control, the control unit controls the locking and unlocking of the doors based on the authentication result of the judging apparatus.

5. The vehicle control system of claim 4, wherein

when the authentication result indicates that the first code and the second code are not identical, the control unit prohibits execution of the request for the door lock control.

6. The vehicle control system of claim 4, wherein

the vehicle controller further comprises a memory that stores the authentication result.

7. The vehicle control system of claim 6, wherein

when the authentication result is not stored in the memory when the request for door lock control is obtained, the judging apparatus verifies the first code and the second code.

8. The vehicle control system of claim 7, wherein

when the authentication result is not stored in the memory, the judging apparatus does not permit the starting of the driving apparatus even when the first code and the second code are identical at the time when the request for door lock control is obtained.
