Car theft and high speed chase prevention device
First Claim
1. A disabling system for a vehicle having a fuel tank, fuel line and a key ignition switch, said disabling system comprising:
- an electromagnetic valve disposed within the fuel tank, said valve reciprocating between an open position and a closed position for controlling fuel flow from the fuel tank through the fuel line;
a first keypad mounted within the vehicle for inputting a first security code;
circuitry having inputs and an output, said circuitry electrically coupled to said first keypad and the ignition switch at said inputs and electrically coupled to said electromagnetic valve at said output;
processor means for comparing the first security code to a stored code, said processor means being coupled to said circuitry and activated by the ignition switch;
receiver means electrically coupled to said circuitry; and
a second remote keypad mounted within a law enforcement vehicle, said second keypad including transmitter means for transmitting an override signal to said receiver means;
wherein said processor means prevents activation of the electromagnetic value and returns the valve to its closed position upon reception by the receiver means of the override signal, thereby disabling the vehicle.

Abstract
The invention relates to a device and system for preventing improper use of a car. The device uses an electronically controlled fuel shut off system located internally of the fuel tank. The system requires the operator of the car to enter a private identification number or PIN code in order to operate the vehicle. In addition, the electronically controlled fuel shut off system is remotely activated allowing law enforcement officials, upon encountering the car being used improperly, to shut off the fuel supply and disable the car. Upon entry of a security code by law enforcement officers, the circuit board stops the flow of current to the fuel shut off system, thereby halting the flow of fuel through the fuel line and shutting down the engine.
