To properly restart an engine which is stopped as an engine travel mode is changed to a motor travel mode.SOLUTION: When switching from an engine travel mode to a motor travel mode, fuel cut is performed where clutch fastening is released and fuel supply to a combustion chamber of an engine is stopped, and a valve phase is changed by a phase variable device into a target phase suitable for restart of the engine. It is determined, based on the valve phase detected by a phase detection unit after the fuel cut, whether the valve phase can be changed to the target phase before the engine stops completely. In a case where it is not possible, an engine transient drive control is performed to give transient torque to the engine so that the timing of the complete stop of the engine is postponed until after the valve phase is changed into the target phase.SELECTED DRAWING: Figure 8

    【課題】エンジン走行モードからモータ走行モードへの切替えに伴い停止したエンジンを適切に再始動する。【解決手段】エンジン走行モードからモータ走行モードへの切替え時に、クラッチの締結を解除しかつエンジンの燃焼室への燃料供給を停止する燃料カットを実行するとともに、位相可変装置によりバルブ位相をエンジンの再始動に適した目標位相に向けて変化させる。そして、燃料カット以後に位相検出部により検出されるバルブ位相に基づいて、エンジンが完全停止する前にバルブ位相が目標位相まで変化することが可能か否かを判定し、不可能と判定した場合には、エンジンの完全停止のタイミングが目標位相への変化完了後まで延期されるようにエンジンに一時的な回転力を付与するエンジン一時駆動制御を実行する。【選択図】図8
