ABSTRACT:
The invention prevents engine speed from being decreased (or engine stall) by a disturbance (such as turning on the air conditioner) during idling. During idle control, a target idle speed is used as an engine speed parameter in place of the actual engine speed to calculate intake air, so that the engine speed is not decreased by a disturbance for very long. Also, target generation torque can be set so as to maintain target idle speed.
