To enable the engine to be started or stopped while performing resonance suppression control without compromising the controllability of drive force even while the vehicle is traveling.SOLUTION: When starting or stopping an engine 22 while a vehicle is traveling, all of required drive force is output from an e-Axle unit 18, with the engine 22 started and stopped while performing resonance suppression control by a first rotary machine MG1 that is separated from an automatic transmission 20 by a second clutch C2, and therefore the resonance suppression control can be appropriately performed using the first rotary machine MG1 without compromising the controllability of drive force.SELECTED DRAWING: Figure 1 【課題】車両走行中であっても駆動力の制御性を損なうことなく共振抑制制御を行いながらエンジンを始動または停止できるようにする。【解決手段】車両走行中にエンジン２２を始動したり停止したりする際に、要求駆動力の全部をｅ−Ａｘｌｅユニット１８によって出力する状態とし、第２クラッチＣ２により自動変速機２０から切り離された第１回転機ＭＧ１で共振抑制制御を行いながらエンジン２２を始動および停止するため、駆動力の制御性を損なうことなく第１回転機ＭＧ１を用いて共振抑制制御を適切に行なうことができる。【選択図】図１
