Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress idle running feeling of a vehicle while supplying negative pressure to a brake booster in a prescribed amount.SOLUTION: When an acceleration pedal treading amount is a predetermined amount or less to become a low required load state, an operation of opening a throttle valve is performed so that intake negative pressure on a downstream side of the throttle valve in an intake passage gets close to target negative pressure required in a brake booster. In this time, when a clutch interposed between a crank shaft and an axle in an internal combustion engine is fastened, a speed at which the throttle valve is opened is made looser than that when the clutch is not fastened.
