To provide a control device that enables responsiveness to an accelerator operation to be secured while suppressing the occurrence of shock even if the accelerator is operated during a switching operation of a mechanical transmission device to a driving position, in a vehicle equipped with an electric motor and the mechanical transmission device.SOLUTION: Even when an accelerator is operated by a driver during execution of quick garage control CTgq and before start of backlash elimination control CTp, a garage control unit 94a continues the quick garage control CTgq, so that resultant shock is suppressed during interruption of the quick garage control CTgq. Meanwhile, an MG rotational speed Nm of an electric motor MG is increased without executing the backlash elimination control CTp executed during a transitional period in which the MG rotational speed Nm of the electric motor MG is increased, responsiveness to the accelerator operation can be advanced according to the increase. It is therefore possible to achieve both suppression of shock that may occur during a switching operation and responsiveness to the accelerator operation.SELECTED DRAWING: Figure 1 【課題】電動機と機械式伝動装置とを備える車両において、機械式伝動装置の走行位置への切替操作時にアクセル操作が為されても、ショックの発生を抑制しつつアクセル操作に対する応答性を担保することができる制御装置を提供する。【解決手段】急速ガレージ制御ＣＴｇｑの実行中であって、ガタ詰め制御ＣＴｐを開始する前に運転者によるアクセル操作が為された場合であっても、ガレージ制御部９４ａは、急速ガレージ制御ＣＴｇｑを継続するため、急速ガレージ制御ＣＴｇｑの中断に起因ショックが抑制される。一方で、電動機ＭＧのＭＧ回転速度Ｎmが上昇させられる過渡期に実行されるガタ詰め制御ＣＴｐを実行することなく電動機ＭＧのＭＧ回転速度Ｎmが上昇させられるため、その分だけアクセル操作に対する応答性を早めることができる。これより、切替操作時に発生するショックの抑制と、アクセル操作に対する応答性とを両立させることができる。【選択図】図１
