Abstract
During a process of increasing the throttle opening when the accelerator pedal is depressed while the vehicle is in a decelerating condition, first throttle opening holding control for holding the throttle opening substantially constant is performed. During the process of increasing the throttle opening after the first throttle opening holding control is finished, second throttle opening holding control for holding the throttle opening substantially constant again is performed.
