ABSTRACT:
For use on an automotive vehicle equipped with an internal combustion engine and an automatic speed control system, a device for detecting accidental engine load removal and for providing disengagement of the speed control system to prevent an engine runaway condition. The device comprises a circuit that compares present engine speed with a previous engine speed furnished after a time delay to produce an output signal when a preselected engine speed differential occurs during the delay period. The output signal is utilized to disengage the speed control system directly or alternatively, to turn off the engine ignition system.
