Abstract
In a cruise-control system mounted on an automobile after a cruise-control mode has been established, a microcomputer prevents the electronic fuel-injection system of the automobile from cutting off the supply of fuel to the engine. This prevents the velocity of the automobile from surging when the automobile does down a hill. Another embodiment of a cruise-control system has an electronic fuel-injection system and an actuator that controls the opening of the throttle valve. When the opening decreases to a small opening slightly larger than the opening at which the fuel-injection system stops supplying fuel to the engine, the fuel-injection system maintains the valve at the small opening.
