Anti-carjacking apparatus
First Claim
1. In combination with a vehicle which includes an ignition circuit, apparatus comprising switch means which is connected in said ignition circuit to be controllable to open the ignition circuit, means for controlling said switch means, both while the vehicle is in operation and while the vehicle is not in operation, to disable operation of the vehicle, means for remotely signaling said controlling means to effect opening of said switch means to disable operation of the vehicle, and means including means for detecting current in the ignition circuit for delaying disabling of operation of the vehicle until a predetermined interval of time elapses after current is detected by said current detecting means in the ignition circuit.

Abstract
Apparatus for disabling operation of a vehicle in the event of an attempted theft thereof. A switch is provided in the ignition circuit. The switch is controlled by a processor which is remotely-controllable to open the ignition circuit to prevent the passage of current therethrough. This switch is thus controllable independently of whether the vehicle is in operation whereby the vehicle may be rendered inoperative even after it is discovered that the vehicle has been driven away by a thief.
