To provide a technique of improving acceleration response of a vehicle after restart of an internal combustion engine including a supercharger.SOLUTION: In a case where an engine speed of an internal combustion engine is faster than a predetermined engine speed when engine stop of the internal combustion engine is required, when exhaust pressure acquired by an exhaust pressure sensor is higher than suction pressure acquired by a suction pressure sensor, a controller of the internal combustion engine is configured to, upon stopping the internal combustion engine, gradually increase opening of a wastegate valve until the exhaust pressure is equal to or less than the suction pressure.SELECTED DRAWING: Figure 7

    【課題】本発明は、過給機を備えた内燃機関の再始動後において、車両の加速レスポンスを向上させる技術を提供することを目的とする。【解決手段】内燃機関の機関停止が要求されたときの該内燃機関の機関回転速度が所定回転速度よりも高い場合において、排気圧センサによって取得された排気圧が吸気圧センサによって取得された吸気圧よりも高いときには、内燃機関を機関停止させるに際し、該排気圧が該吸気圧以下となるまで、ウェイストゲートバルブの開度を徐々に大きくする。【選択図】図7
