ABSTRACT:
An idle speed control device for smoothly executing a transition from an idle state where engine speed is feedback controlled to a non-idling state where open-loop control is employed. The device includes an idling state determination section for determining whether the engine is in an idling state or a non-idling state, a feedback control section for controlling an idling control valve so that the engine rotation speed matches a target value in the idling state, a valve opening amount maintaining section for, when shifting from the idling state to a non-idling state, maintaining the idling control valve at the opening amount at the time of feedback control until the throttle opening amount reaches a reference opening amount, and an open loop control section for controlling the idling control valve to the target valve opening amount open if the throttle opening amount reaches the reference opening amount in the non-idling state.
