Claim:
1. An emergency forced idle device for use with an automobile for improving safety, the automobile including an engine: an induction manifold; an accelerator pedal; a brake pedal for actuating the brakes, the emergency forced idle device comprising: an ECU ( 57 ) and circuitry, wherein the circuitry includes a vacuum switch ( 54 ), a throttle position shuttle relay ( 40 ), a first throttle position sensor ( 55 ) and a second throttle position sensor ( 55 A) with a preset fixed idle voltage, wherein the ECU ( 57 ) and circuitry control the engine to idle and the brakes to continue working normally, when both the brake and the accelerator pedal are being pressed at the same time by increasing the intake manifold vacuum by actuating the vacuum switch ( 54 ), at the same time the activation of the throttle position shuttle relay ( 40 ) stops the ECU ( 57 ) from monitoring the throttle position sensor ( 55 ), but sends the preset idle voltage exiting the second throttle position sensor ( 55 A) to the ECU ( 57 ).
