Abstract
A vehicle security system includes a portable transmitter remote control unit for transmitting an arming signal or a disarming signal, a receiver unit mounted on the vehicle for receiving the arming or disarming signal from the transmitter unit, a detector for detecting the gear shift lever park position, an arming-signal reception monitor unit capable of receiving the arming signal from the transmitter unit only if the gear shift lever is in 'park', and only if the vehicle door has just been opened and then closed and a security control unit activated to arm the system in response to the arming signal transmitted from the transmitter unit only when the arming-signal reception monitor unit can receive the arming signal. Since the transmission lever cannot be in the 'park' position while the vehicle is in motion, the system cannot be armed by the accidental operation of the transmitter unit while the vehicle is in motion.
