ABSTRACT:
An anti-hijacking and anti-theft vehicle security protection system is designed to permit, in the anti-hijacker function, the hijacker to drive off with the vehicle but within about two minutes the engine will be partially disabled to permit maneuvering the vehicle out of traffic to the side of the road. A few minutes later, the engine will be totally disabled and signalling devices can be activated. The system employs two overlapped timers under control of a sensor relay. A reset button under control of an authorized user can deenergize the sensor relay to return the system to normal. Also included within the design is anti-theft protection for an unattended vehicle which can be selected to function in any one of 3 conditions, one condition being the anti-hijacking function. In the second condition, operation of the vehicle is first partially disabled and then completely shut off. In the third condition, the vehicle cannot be started, and hazard lights and alarm are activated.
