Abstract

A vehicle controller installed in and controlling a vehicle includes an obtaining part that obtains identification information specific to the vehicle, a communicator that communicates with an information processor located outside the vehicle by transmitting and receiving information, a match judging part that makes a matching judgment on whether a plurality of the identification information obtained at different times are identical, and a judging part that judges whether to permit the control of the vehicle based on the matching judgment. The information processor also can make the matching judgment and only transmit a control command to the vehicle controller when there is a match.

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 communicator that communicates with an information processor that is located outside the vehicle by transmitting and receiving information; and

a control unit configured to;

(i) obtain identification information specific to the vehicle,

(ii) make a matching judgment on whether a plurality of the identification information obtained at different times are identical or not, and

(iii) judge whether to permit the control of the one or more operations of the vehicle based on the matching judgment, wherein

upon reception of a request for the control of the one or more operations of the vehicle from the information processor, the control unit obtains updated data of the identification information,

the control unit makes the matching judgment on whether previous data of the identification information stored in the information processor and the updated identification information are identical or not, and

the control unit permits the control of the one or more operations of the vehicle when the previous identification information and the updated identification information are identical, and does not permit the control of the one or more operations of the vehicle when the previous identification information and the updated identification information are not identical.

2. The vehicle controller according to claim 1, wherein the one or more operations of the vehicle include a door lock/unlock operation.

3. The vehicle controller according to claim 1, wherein the one or more operations of the vehicle include a vehicle ignition start/stop operation.

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

a detector that detects reconnection of a battery of the vehicle;

a communicator that communicates with an information processor that is located outside the vehicle by transmitting and receiving information; and

a control unit configured to;

(i) obtain identification information specific to the vehicle,

(ii) make a matching judgment on whether a plurality of the identification information obtained at different times are identical or not, and

(iii) judge whether to permit the control of the one or more operations of the vehicle based on the matching judgment, wherein

when the detector detects the reconnection of the battery, the control unit obtains updated data of the identification information,

the control unit makes the matching judgment on whether previous data of the identification information stored in the information processor and the updated identification information are identical or not, and

the control unit permits the control of the one or more operations of the vehicle when the previous identification information and the updated identification information are identical, and does not permit the control of the one or more operations of the vehicle when the previous identification information and the updated identification information are not identical.

5. The vehicle controller according to claim 4, wherein the one or more operations of the vehicle include a door lock/unlock operation.

6. The vehicle controller according to claim 4, wherein the one or more operations of the vehicle include a vehicle ignition start/stop operation.

7. An information processor that is outside of a vehicle and that is configured to be communicatively coupled to a mobile terminal and to the vehicle, and that, when receiving a request for control of one or more operations of the vehicle from the mobile terminal, transmits the request for the control of the one or more operations to the vehicle, the information processor comprising:

a communicator that communicates with the mobile terminal and with the vehicle by transmitting and receiving information;

a memory that stores identification information that is specific to the vehicle and that is sent from the vehicle; and

a control unit configured to;

(i) make a matching judgment on whether a plurality of the identification information obtained at different times are identical or not, and

(ii) judge whether to permit transmission of the request for the control of the one or more operations of the vehicle based on the matching judgment, wherein

when receiving the request for the control of the one or more operations of the vehicle from the mobile terminal, the communicator obtains updated data of the identification information from the vehicle,

the control unit makes the matching judgment on whether previous data of the identification information stored in the memory and the updated identification information are identical or not, and

the control unit permits the transmission of the request for the control of the one or more operations of the vehicle when the previous identification information and the updated identification information are identical, and does not permit the transmission of the request for the control of the one or more operations of the vehicle when the previous identification information and the updated identification information are not identical.

8. The information processor according to claim 7, wherein the one or more operations of the vehicle include a door lock/unlock operation.

9. The information processor according to 7, wherein the one or more operations of the vehicle include a vehicle ignition start/stop operation.

10. An information processor that is outside of a vehicle and that is configured to be communicatively coupled to a mobile terminal and to the vehicle, and that, when receiving a request for control of one or more operations of the vehicle from the mobile terminal, transmits the request for the control of the one or more operations to the vehicle, the information processor comprising:

a communicator that communicates with the mobile terminal and with the vehicle by transmitting and receiving information;

a memory that stores identification information that is specific to the vehicle and that is sent from the vehicle; and

a control unit configured to;

(i) make a matching judgment on whether a plurality of the identification information obtained at different times are identical or not, and

(ii) judge whether to permit transmission of the request for the control of the one or more operations of the vehicle based on the matching judgment, wherein

when the communicator receives updated data of the identification information obtained at reconnection of a battery of the vehicle, the control unit makes the matching judgment on whether the updated identification information and previous data of the identification information stored in the memory are identical or not, and

the control unit permits the transmission of the request for the control of the one or more operations of the vehicle when the previous identification information and the updated identification information are identical, and does not permit the transmission of the request for the control of the one or more operations of the vehicle when the previous identification information and the updated identification information are not identical.

11. The information processor according to claim 10, wherein the one or more operations of the vehicle include a door lock/unlock operation.

12. The information processor according to claim 10, wherein the one or more operations of the vehicle include a vehicle ignition start/stop operation.
