This patent describes a vehicular cruise and engine idling speed control system. This system consists of: 1.) An actuator adapted for engagement to a vehicular engine throttle that in a first engaged condition is operable upon receipt of a first control signal to move the throttle to regulate the vehicle speed. In a second engaged condition the engine throttle is operable upon receipt of a second control signal to regulate engine idling speed independent of the vehicle speed, 2.) A controller which responds to a sensed vehicle speed and an operator selected vehicle speed to provide the first and second control signal from at least one sensed engine operating condition upon establishment of the second engaged condition, 3.) An operator control for establishment of the first and second engaged conditions, 4.) A sensor throttle, actuated by the operator, is functionally effective for switching the controller output from the second control signal to the first control signal and causes the actuator to position the throttle at an advanced engine idle speed pick-up position, 5.) A device for differentiating between the operator selected vehicle speed throttle position and the regulated engine idle speed pick-up throttle position, 6.) A mechanism for insuring that the engine speed decreases in a uniform manner from the engine idle speed pick-up throttle position to the regulated engine idle speed throttle position.
