ABSTRACT:
Engine rotation speed during idle running is feedback-controlled. A second target rotation speed which progressively decreases towards a first target rotation speed from a predetermined engine rotation speed, is set. The engine rotation speed is feedback-controlled based on a difference between a present rotation speed and this second target rotation speed. In this way, compared to the case where feedback control is performed using the first target rotation speed as a target value, the time period during which the engine rotation speed falls below the first target rotation speed is shortened and the engine rotation speed is made to stably converge to the first target rotation speed.
