A governor is disclosed for governing engine and road speed for motor vehicles. A movable overriding throttle closing device limits the speed to governed values. An actuator for the device is moved by a reversible motor to a reference position when a speed call-in value is reached and the actuator is moved at slow speed to maintain the governed speed. The actuator is moved to an intermediate position closely adjacent to the reference position for speeds below the call-in value. An engine power demand control system is provided to cause the actuator to be moved in the wide open throttle direction in response to a sustained power demand.

A speed limiting governor for use with an engine having a throttle movable between an open throttle position and a close throttle position for regulating the flow of fuel to the engine, said governor being of the type comprising an overriding throttle closing means, an engine speed signal generating means for producing a signal corresponding to engine speed, a load speed signal generating means for producing a signal corresponding to load speed, actuating means including a reversible motor coupled with the overriding throttle closing means and being responsive to motor control signals for energizing the motor in the close throttle direction or in the open throttle direction, logic means responsive to the engine speed signal and the load speed signal for producing motor control signals for moving the overriding means between a wide open throttle position and a close throttle position and to intermediate positions including a reference position, said logic means being responsive to said speed signals for moving said overriding means in the close throttle direction to said reference position when the engine speed reaches a first preset value, and means responsive to engine power demand for energizing said motor to move said overriding means from said reference position toward said open throttle position.
