Abstract
A throttle valve control apparatus serves to electrically drive a throttle valve which adjusts a rate of air flow into an engine mounted on a vehicle. The throttle valve control apparatus includes a lever connected to the throttle valve for movement in an opening direction and a closing direction together with the throttle valve. An opening degree limiting member is located in a side of the lever which corresponds to the opening direction. A spring urges the opening degree limiting member in a direction of closing the throttle valve. An accelerator interlocking and driving device serves to move the opening degree limiting member in accordance with a degree of operation of an accelerator member. A throttle actuator functions to adjust a degree of opening of the throttle valve. A vehicle speed sensor functions to detect a running speed of the vehicle. A guard actuator serves to adjust a position of the opening degree limiting member. An auto cruise control device serves to control the throttle actuator and to feedback-control the vehicle speed detected by the vehicle speed sensor at a target vehicle speed. A guard control means serves to control the guard actuator and to adjust the p…
