Abstract

The present invention discloses an antitheft apparatus mounted on a vehicle for protecting the vehicle from theft. The vehicle has a remote control device that controls a vehicle component of the vehicle in accordance with a control signal transmitted from a terminal. The antitheft apparatus includes an intruder detection part for detecting intrusion of an intruder, and an intrusion detection control part for controlling the detecting function of the intruder detection part during a period when the vehicle component is being controlled by the remote control device.

Claims

1. An antitheft apparatus mounted on a vehicle for protecting the vehicle from theft, said vehicle having a remote control device that controls a vehicle component of said vehicle in accordance with a control signal transmitted from a terminal, the antitheft apparatus comprising:

an intruder detection part for performing a detection function of detecting intrusion by an intruder; and

an intrusion detection control part for restraining the detection function of the intruder detection part during activation of a vehicle component being controlled by the remote control device, said vehicle component including at least one of a door, a window, a sliding roof, and an air conditioner.

2. The antitheft apparatus as claimed in claim 1, further comprising:

an alarm device for sounding an alarm when intrusion is detected by the intruder detection part;

wherein the alarm device is deactivated by the intrusion detection control part during the period when the vehicle component is being controlled by the remote control device.

3. The antitheft apparatus as claimed in claim 2, wherein the intrusion detection control part is configured to deactivate the detection function of the intruder detection part.

4. The antitheft apparatus as claimed in claim 3, wherein the intrusion detection control part is configured to deactivate the alarm device before the intrusion detection control part deactivates the detection function of the intruder detection part, and is configured to activate the deactivated alarm device after the intrusion detection control part deactivates the detection function of the intruder detection part.

5. The antitheft apparatus as claimed in claim 1, wherein the intrusion detection control part is configured to lower the a detection sensitivity of the intruder detection part.

6. The antitheft apparatus as claimed in claim 1, wherein the intrusion detection control part is configured to extend a time period in which the intruder detection part detects intrusion.

7. The antitheft apparatus as claimed in claim 1, wherein the intrusion detection control part is configured to return the detection function of the intruder detection part back to a state existing before being controlled by the intrusion detection control part after the remote control device finishes controlling the vehicle component being controlled by the remote control device.

8. The antitheft apparatus as claimed in claim 1, wherein the intrusion detection part is configured to detect intrusion of an intruder by detecting vibration.
