In-vehicle security system

摘要

A vehicle having an anti-theft system, a door assembly, a controller and a remote keyless entry fob. The anti-theft system is selectively operable in an armed condition for electrically disconnecting a vehicle battery and grounding a vehicle electrical system to ground in response to a detected unauthorized vehicle start-up and an unarmed condition. The door assembly has a latch mechanism and a latch lock device. The latch lock device is selectively operable in an unlocked condition and a locked condition, wherein the locked condition prevents the latch mechanism from being positioned in the unlatched condition. The controller is coupled to the latch lock device and the anti-theft system. The remote keyless fob is operable for selectively transmitting a lock or unlock signals to the controller. Transmission of the lock signal to the controller causes the controller to generate a first latch lock control signal and a first anti-theft control signal. The first latch lock control signal causes locking of the latch lock. The first anti-theft system control signal causes the anti-theft system to generate a first actuation signal employed to arm the anti-theft system. Transmission of the unlock signal to the controller causes the controller to generate a second latch lock control signal and a second anti-theft system control signal. The second latch lock control signal causes unlocking of the latch lock. The second anti-theft system control signal causes the anti-theft system to generate a second actuation signal employed to disarm the anti-theft system.
