When an IDLE switch goes on and so a condition of strong possibility of fuel cutoff is obtained, a throttle degree of opening is immediately opened slightly and an IDLE switch goes off, and thereby actual entry of an electronic-control fuel-injection device into fuel cutoff processing can be prevented. Moreover regulation of the throttle degree of opening to a closed side is blunted by enlargement of an insensitive zone of a difference between target cruising speed and vehicle speed, and so the throttle degree of opening does not change and a rise of vehicle speed Vn continues for a while. Because of this, a large cycle of vehicle change is repeated and so physical sensations do not deteriorate.
