Abstract

A robbery prevention system for a vehicle that registers ID information at the time of replacement of a lock controller. A portable device such has a key has exclusive ID information. A lock controller locks or unlocks a control target device according to an authentication result of the portable device. An auxiliary controller transmits and receives data to and from the lock controller and stores the ID information of the portable device as backup data. The lock controller receives the ID information from the auxiliary controller, and transmits a response requiring signal for searching the portable device which has the ID information received from the auxiliary controller and is present within a predetermined detection range. Then, the lock controller stores the ID information of the portable device which has transmitted a response signal to the response requiring signal.

Claims

1. A robbery prevention system, comprising:

a portable device that has ID information provided exclusively for the portable device;

a lock controller that has memory means which stores the ID information, authenticates the portable device based on the ID information stored in the memory means and the ID information received from the portable device, and locks or unlocks a control target device according to the authentication result; and

an auxiliary controller that transmits and receives data to and from the lock controller and stores the ID information of the portable device as backup data, wherein the lock controller includes;

receiving means that receives the ID information from the auxiliary controller, and

searching and storing means that transmits a response requiring signal for searching the portable device which has the ID information received by the receiving means from the auxiliary controller and is present within a predetermined detection range, and stores the ID information of the portable device which has transmitted a response signal to the response requiring signal in the memory means.

2. The robbery prevention system according to claim 1, wherein the ID information is allocated to the portable device in advance.

3. The robbery prevention system according to claim 1, and further comprising an operation device, wherein

the control target device restricts operation of the operation device;

and

operation of the operation device is restricted when the control target device is locked and allowed when the control target device is unlocked.

4. The robbery prevention system according to claim 1, wherein:

the lock controller further includes detecting means that detects replacement of the lock controller; and

the searching and storing means stores the ID information of the portable device having transmitted the response signal to the response requiring signal at the time of replacement of the lock controller.

5. The robbery prevention system according to claim 4, wherein the detecting means judges that the lock controller has been replaced when the memory means of the lock controller does not have the ID information.

6. The robbery prevention system according to claim 1, wherein the searching and storing means of the lock controller stores a predetermined number of the ID information in the memory means.

7. The robber prevention system according to claim 1, wherein the auxiliary controller further includes backup renewing means that renews the ID information stored in the memory means of the auxiliary controller as backup data according to predetermined timing.

8. A vehicle comprising the robbery prevention system according to claim 1.

9. A method for registering ID information in a replacement lock controller of a vehicle robbery prevention system, comprising:

judging that a replacement lock controller has been attached to the vehicle;

obtaining portable device IDs and lock controller IDs stored as backup data in an auxiliary lock unit;

storing the obtained lock controller ID in the replacement lock controller;

identifying portable devices that have IDs corresponding to those obtained from the auxiliary lock unit and that are within communication range of the replacement lock controller; and

storing the IDs of the portable devices determined to be within communication range in the replacement lock controller.

10. The method according to claim 9, wherein the replacement lock controller is judged to be attached to the vehicle when no portable device IDs are stored in the replacement lock controller.

11. The method according to claim 9, and further comprising:

authenticating the replacement lock controller by the auxiliary lock unit before providing the portable device IDs and lock controller IDs to the replacement lock controller.

12. The method according to claim 11, and further comprising:

encoding the portable device IDs and lock controller IDs provided by the auxiliary lock unit to the replacement lock controller.

13. The method according to claim 9, and further comprising:

transmitting the lock controller ID from the replacement lock controller to those portable devices having IDs corresponding to those obtained from the auxiliary lock unit and determined to be within communication range of the replacement lock controller.

14. The method according to claim 9, and further comprising the step of:

indicating with an indicator light whether ID information has been successfully registered in the replacement lock controller.

15. The method according to claim 9, and further comprising:

periodically renewing the backup data stored in the auxiliary lock unit by overwriting the portable device IDs stored in the auxiliary lock unit when they do not coincide with the portable device IDs stored in the replacement lock controller.
