Zusammenfassung:	To suppress influence of clutch engagement at the time of re-startup of an engine on cooperative regenerative control and switching of braking, in a hybrid vehicle mounted with a P2 module.SOLUTION: A control device of a hybrid vehicle includes an engine 4, a motor 5, a K0 clutch 6, a drive shaft 17, a frictional brake system 3 of a fluid pressure type, and a controller 20 that can perform cooperative regenerative control. When startup of the engine 4 is requested during cooperative regenerative control, the controller 20 performs first processing of making a transition to braking only by the frictional brake system 3. After the transition of the braking is completed, the controller 20 performs second processing of increasing the output rotation speed of the engine 4 while starting engagement of the K0 clutch 6. After the engagement of the K0 clutch 6 is started, the controller 20 performs third processing of causing the engine 4 to resume operation at a timing after the engine rotation speed has been increased up to matching the motor rotation speed.SELECTED DRAWING: Figure 7 【課題】Ｐ２モジュールが搭載されたハイブリッド車両において、エンジンの再始動時におけるクラッチの締結が、協調回生制御、及び制動の切替に及ぼす影響を抑制する。【解決手段】ハイブリッド車両の制御装置は、エンジン４と、モータ５と、Ｋ０クラッチ６と、駆動シャフト１７と、液圧式の摩擦ブレーキシステム３と、協調回生制御を実行可能なコントローラ２０と、を備える。コントローラ２０は、協調回生制御中にエンジン４の始動が要求された際には、摩擦ブレーキシステム３のみによる制動へと移行させる第１処理と、制動の移行が完了した後、Ｋ０クラッチ６の締結を開始しつつエンジン４の出力回転数を上昇させる第２処理と、Ｋ０クラッチ６の締結を開始した後、エンジン回転数がモータ回転数に一致するまで上昇した以降のタイミングでエンジン４に運転を再開させる第３処理と、を実行する。【選択図】図７
