Abstract

A control system for improving the security level of a security device. A portable device is provided with a communication function and has a portable device ID code. A security controller includes a memory for recording a controller ID code. The security controller communicates with the portable device to determine whether the portable device ID code matches the controller ID code, and controls deactivation of security functions for a door lock driver and an engine controller based on the determination result. In response to a restriction request signal, the management apparatus transmits a function restriction signal to the security controller. The security controller prohibits or restricts control of the door lock driver or the engine controller when receiving the function restriction signal and communicating with the portable device.

Claims

1. A system for controlling a security device provided with a security function, the system comprising:

a portable device provided with a communication function and having a portable device ID code;

a security controller including a recording unit for recording a controller ID code, wherein the security controller communicates with the portable device to determine whether the portable device ID code and the controller ID code match, and controls deactivation of the security function of the security device based on the determination result; and

a management apparatus for transmitting a function restriction signal to at least one of the portable device and the security controller in response to a restriction request signal;

wherein the security controller prohibits or restricts control of the security device when receiving the function restriction signal or when communicating with the portable device that has received the function restriction signal; and

wherein the security controller;

communicates with the portable device and records the portable device ID code in the recording unit as the controller ID code; and

prohibits recording of the portable device ID code in the recording unit in order to prohibit control of the security device when receiving the function restriction signal or when communicating with the portable device that has received the function restriction signal.

2. The system according to claim 1, wherein the security controller prohibits communication with the portable device when receiving the function restriction signal.

3. The system according to claim 1, wherein:

the portable device transmits a transmission signal, containing a function restriction code, to the security controller when receiving the function restriction signal; and

the security controller prohibits or restricts control of the security device in accordance with the function restriction code when receiving the transmission signal.

4. The system according to claim 1, wherein:

the restriction request signal is transmitted from a mobile device;

the management apparatus includes a communication unit for receiving the restriction request signal, and transmits the function restriction signal when the communication unit receives the restriction request signal.

5. The system according to claim 1, wherein the management apparatus:

communicates with a mobile device operated by a user; and

transmits to the mobile device a notification signal indicating transmission of the function restriction signal when transmitting the function restriction signal to at least one of the portable device and the security controller.

6. The system according to claim 1, wherein the system is for use in a vehicle having a door and an engine, and the security device includes at least one of a door lock driver, for locking and unlocking a vehicle door, and an engine control unit, for controlling enablement of engine starting.

7. The system according to claim 1, wherein:

the restriction request signal contains a portable device designation code for designating a portable device;

the management apparatus transmits the function restriction signal containing the portable device ID code associated with the portable device destination code to the security controller; and

the security controller prohibits or restricts deactivation of the security function of the security device in accordance with the portable ID code contained in the function restriction signal.

8. The system according to claim 7, wherein the security controller prohibits or restricts control of the security device when receiving the portable device ID code from the portable device corresponding to the portable device ID code contained in the function restriction code.

12. The system according to claim 1, the management apparatus comprising:

at least one of a management communication unit and a portable device communication unit, the management communication unit communicating with the security controller, and the portable device communication unit communicating with the portable device; and

a management control unit for transmitting a function restriction signal when receiving a restriction request signal to at least one of the security controller and the portable device via the at least one of the management communication unit and the portable device communication unit, wherein the function restriction signal prohibits or restricts deactivation of a security function of a security device.

13. The system according to claim 12, wherein the management apparatus is used with a mobile device for transmitting the restriction request signal, the management apparatus further comprising:

a mobile device communication unit for receiving the restriction request signal from the mobile device and providing the restriction request signal to the management control unit.

9. A security controller for use with a portable device, having a portable device ID code, and a management apparatus, for transmitting a function restriction signal, wherein the security controller controls a security device provided with a security function, the security controller comprising:

a portable device communication unit for communicating with the portable device;

a recording unit for recording a controller ID code corresponding to the portable device ID code;

a control unit for determining whether the portable device ID code matches the controller ID code and controlling the security device based on a determination result; and

a security communication unit for communicating with the management apparatus;

wherein the control unit prohibits or restricts deactivation of the security function of the security device when the security communication unit receives the function restriction signal; and

wherein the control unit;

communicates with the portable device and records the portable device ID code in the recording unit as the controller ID code; and

prohibits recording of the portable device ID code in the recording unit in order to prohibit or restrict control of the security device when the security communication unit receives the function restriction signal.

10. The controller according to claim 9, wherein the control unit prohibits communication with the portable device when the security communication unit receives the function restriction signal.

11. The controller according to claim 9, wherein the control unit prohibits deactivation of the security function of the security device when at least one of the security communication unit and the control unit is not operating normally.

14. A security control method for use with a portable device, having a portable device ID code, a security controller, having a controller ID code, and a management apparatus, for communicating with the security controller, wherein the security controller determines whether the portable device ID code matches the controller ID code and controls deactivation of a security function of a security device based on the determination result, the method comprising:

transmitting a restriction request signal for function restriction to the management apparatus;

transmitting a function restriction signal with the management apparatus to at least one of the portable device and the security controller in response to the restriction request signal;

communicating with the portable device and recording the portable device ID code in the recording unit as the controller ID code; and

prohibiting recording of the portable device ID code in the recording unit in order to prohibit control of the security device when receiving the function restriction signal or when communicating with the portable device that has received the function restriction signal.

15. The method according to claim 14, wherein said transmitting a restriction request signal includes transmitting the restriction request signal from a mobile device, held by a user, to the management apparatus when the user operates the mobile device.
