ABSTRACT:
Undershoot of rotation speed is prevented by increasing an intake air amount of an engine when it decelerates. Precise control corresponding to differences of a deceleration state is realized by setting an increase amount of intake air to a different value according to the engine rotation speed and deceleration. Preferably, increasing of intake air amount starts when the engine rotation speed reaches a first predetermined value. It is terminated when the engine rotation speed reaches a second predetermined value smaller than the first predetermined value or when a predetermined time has elapsed, whichever is the sooner.
