Abstract
Disclosed is a system for controlling both cruising speed and engine idling speed of a vehicle. The system includes an electronic control module that controls an actuator (100) having a moveable member preferably in the form of a gear rack (6) that is pivotably mounted to an intermediate member (8) that is operably connected to the engine throttle and adapted to move in opposite directions along a frame (2) of the actuator. The actuator is provided with means, preferably in the form of an idle speed control switch (34), for sensing when the throttle is being controlled by the operator and causing the control module to switch its output from a second control signal to a first control signal and feedback means, preferably in the form of a differentiating switch (47), for determining an idle speed pick-up position for the moveable member that is more than the desired regulated engine idle speed position but not more than the operator selected cruising speed position.
