To suppress a reduction of the cruising distance due to the power consumption caused by shifting of an automatic transmission when an electric motor is operated by an electric power supplied from a power storage device to cause a vehicle to perform a limp-home running.SOLUTION: During a limp-home running in which an electric motor MG is operated by an electric power supplied from a power storage device, a gear position Gr of an automatic transmission is limited to a limp-home-running gear position Gr1 or a low-speed gear position Gr2 to suppress shifting of the automatic transmission, and therefore it is possible to suppress power consumption caused by control of rotational speed of the electric motor MG for suppressing shifting shock or the like, so as to extend a cruising distance of a vehicle accordingly.SELECTED DRAWING: Figure 5 【課題】蓄電装置からの電力供給で電動機を作動させて退避走行する際に、自動変速機の変速に伴う電力消費によって航続距離が短くなることを抑制する。【解決手段】蓄電装置からの電力供給により電動機ＭＧを作動させて走行する退避走行中は、自動変速機のギヤ段Ｇｒが退避走行ギヤ段Ｇｒ１または低車速ギヤ段Ｇｒ２に制限されて変速が抑制されるため、変速ショック等を抑制するための電動機ＭＧによる回転速度制御等に起因する電力消費が抑制され、その分だけ車両の航続距離を延ばすことができる。【選択図】図５
