PROBLEM TO BE SOLVED: To suppress reduction of opportunities for performing electrically-driven travel.SOLUTION: When an acceleration request is executed during stopping of rotation of an engine from an HV travel mode, the engine is re-started thereby returning to the HV travel mode (S120) in the case that it is predicted that an engagement sound at a one-way clutch exceeds an acceptable range (such an engagement sound can be heard by a user) if shifting to both drive modes (S100 to S112), and shifting to both drive modes in the EV travel mode (S130) in the case that it is predicted that the engagement sound at the one-way clutch falls in the acceptable range (the engagement sound is not generated, or the engagement sound cannot be heard by the user) even if shifting to both drive modes (S100 to S112).SELECTED DRAWING: Figure 2 【課題】電動走行を行なう機会が減少するのを抑制する。【解決手段】ＨＶ走行モードからのエンジンの回転停止処理中に加速要求が行なわれたとき、両駆動モードに移行するとワンウェイクラッチでの係合音が許容範囲を超える（ユーザに聞こえる）と予測されるときには（Ｓ１００〜Ｓ１１２）、エンジンを再始動してＨＶ走行モードに復帰し（Ｓ１２０）、両駆動モードに移行してもワンウェイクラッチでの係合音が許容範囲内になる（係合音が生じないまたは係合音がユーザに聞こえない）と予測されるときには（Ｓ１００〜Ｓ１１２）、ＥＶ走行モードにおける両駆動モードに移行する（Ｓ１３０）。【選択図】図２
