An electronic governor control for an automotive engine that prevents the speed of the engine from exceeding a predetermined limit. The electronic circuitry responds to ignition pulses and limits the throttle opening of the vehicle to maintain the predetermined speed limit. The electronic governor control also includes circuitry to prevent engine overshoot of the predetermined limit by monitoring the rate of acceleration and adjusting the predetermined limit to anticipate and initiate governor control prior to the engine reaching the predetermined speed limit. Circuitry is also included which allows the governor control to retain control of the engine until the accelerator control reduces the speed of the engine to a speed value below the predetermined limit.

An electronic engine governor control being responsive to the speed parameter of an associated engine for limiting said speed to a predetermined maximum amount, by regulating the throttle opening, comprising: means connecting said control to the ignition system of said associated engine and producing a voltage having a value which varies with respect to the speed of said engine; means for supplying a reference voltage corresponding to said predetermined maximum speed limit; means for comparing said reference voltage with said variable voltage and producing an output signal when said voltages are approximately equal; means responsive to said output signal for correspondingly regulating said throttle opening; and means responsive to said output signal for supplying said reference voltage to said comparing means adjusted by an amount related to said output signal to prevent engine speed limit overshoot at low to medium acceleration rates; wherein said low to medium acceleration rate overshoot prevention means includes a pre-bias means, which normally outputs a DC voltage superimposed on said reference voltage at said comparing means for offsetting said predetermined maximum speed limit to a lower speed, and a feed forward means, connected to said comparing means and said pre-bias means, which responds to the comparing means output signal exceeding a predetermined level and lowers the pre-bias means DC output voltage.
