<p><P>PROBLEM TO BE SOLVED: To solve the problem that when a user of a vehicle makes the vehicle continuously vibrate by sweeping snow laid on a car body in the state that an alarm system is operating, an intrusion sensor erroneously detects the intrusion into a cabin, and an alarm system receives the signal from the intrusion sensor and erroneously outputs a warning. <P>SOLUTION: A user recognizing means receives a signal from a portable transmitter carried by a registered user, and judges whether or not the registered user is approaching to the vehicle. When the user recognizing means has detected the approach of the registered user to the vehicle, a sensitivity control means outputs a sensitivity control signal to the intrusion sensor so as to temporarily lower the detecting sensitivity of the intrusion sensor. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
