To curb a reduction in start performance while preventing a driver from having a feeling of strangeness due to a reduction in power performance in evacuation running.SOLUTION: In a case of abnormality related to power transmission through a power transmission path capable of transmitting power of engine, etc. to drive wheels when a vehicle speed is equal to or higher than a predetermined speed, an evacuation running control section switches a running mode to a first evacuation running mode enabling the power of engine, etc. to be transmitted through the power transmission path and thereby enabling a vehicle to perform evacuation running using the power of engine, etc. when the same is running at a relatively high speed. Also, in the case of abnormality related power transmission through the power transmission path when the vehicle speed is lower than the predetermined speed, the evacuation running control section switches the running mode to a second evacuation running mode enabling the evacuation running to be performed using a second motor and thereby enabling the evacuation running to be performed without transmitting the power through the power transmission path with abnormality when the vehicle is running at a relatively low speed or stopped.SELECTED DRAWING: Figure 1 【課題】退避走行を行うに際して、動力性能の低下による運転者の違和感を抑制しつつ発進性能の低下を抑制する。【解決手段】退避走行制御部により、エンジンの動力等を駆動輪へ伝達可能に形成される動力伝達経路における動力伝達に関わる異常が発生している場合に、車速が所定車速以上であるときには、前記動力伝達経路においてエンジンの動力等を駆動輪へ伝達可能な第１退避走行モードへ切り替えられるので、比較的高車速域での走行中には、エンジン等の動力を用いた退避走行を行うことが可能となる。又、退避走行制御部により、前記動力伝達経路における動力伝達に関わる異常が発生している場合に、車速が前記所定車速よりも低いときには、第２電動機の動力を用いて退避走行を行う第２退避走行モードへ切り替えられるので、比較的低車速域での走行中や車両停止中には、異常が発生している動力伝達経路を介することなく退避走行を行うことが可能となる。【選択図】図１
