Abstract
In such an operation mode that the vehicle is accelerated upon turning-on of the switch and, when the vehicle has reached a given vehicle speed, the switch is turned off to memorize the vehicle speed at that time for effecting constant-speed control at the memorized vehicle speed, a throttle valve is returned to apply the engine brake after turning-off of the switch. If at least one of several given conditions is satisfied, adjustment of opening degree of the throttle valve is started so as to maintain the current vehicle speed at the goal vehicle speed. This makes smaller overshoot of the controlled vehicle speed caused by a response deley of the vehicle. The given condition may be related to differences between current speed and set speed, elapsed time, elapsed distance, or degree of acceleration.
