PURPOSE:To prevent a lack of intake air due to a delay of control during an operation with an accelerator depressed slightly by using a control value stored prior to the open action of a throttle valve as the control value immediately after the open action when the throttle valve is opened in a range of a predetermined opening or less. CONSTITUTION:Normally, a proportional solenoid valve 48 in a bypass passage 46 bypassing a throttle valve 42 is controlled by a control unit 52 so that the engine speed detected by a rotation sensor 54 converges on a target idle speed. The control value of the proportional solenoid valve 48 at this time is stored in a memory means, and when a slight depressing action of an accelerator pedal during idling is detected via the output signal of a throttle valve opening sensor 50, the control value at this time is stored. At the same time, the feedback control of idle rotation is stopped. Then, when the completion of a slight depressing action of the accelerator is detected, the control of the said valve 28 is restarted by using the control value stored prior to the interruption of the feedback control. |
