<p><P>PROBLEM TO BE SOLVED: To provide a vehicle anti-theft system which can prevent a false alarm without directly determining a reduction in a battery voltage. <P>SOLUTION: The vehicle anti-theft system monitors a power supply voltage for a tilt sensor Vcc2. When the power supply voltage for the tilt sensor Vcc2 comes outside a threshold range, theft alarm action is temporarily halted, and when the power supply voltage for the tilt sensor Vcc2 returns within the threshold range, the theft alarm action is restarted. As a result, when the power supply voltage for the tilt sensor Vcc2 comes outside a predetermined voltage range, the vehicle anti-theft system prevents the theft alarm action from activating and can prevent the false alarm. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
