Zusammenfassung:To provide a control device which can reduce the sliding-down of a vehicle which occurs when a shift operation position is operated to a traveling position, in the vehicle comprising an electric motor and a mechanical transmission device having a prescribed engagement device.SOLUTION: When an AT output rotational speed No of an automatic transmission 24 having a correlation with a vehicle speed V reaches a prescribed rotational speed No1 or higher during garage control CTg, a garage control part 96a prohibits backlash control CTp, and raises a target rotational speed Nmf. Also, when the sliding-down of a vehicle 10 is detected, the garage control part prohibits the backlash control CTp, and quickly raises an MG rotational speed Nm of an electric motor MG to the target rotational speed Nmf or higher, to thereby generate creep torque Tcrp. Therefore, the sliding-down of the vehicle 10 can be quickly eliminated, and an incongruity imparted to a driver resulting from the sliding-down of the vehicle 10 can be suppressed.SELECTED DRAWING: Figure 1 【課題】電動機と、所定係合装置を備えて構成される機械式伝動装置と、を備える車両において、シフト操作位置が走行位置に操作されたときに発生する車両のずり下がりを低減できる制御装置を提供する。【解決手段】ガレージ制御部96aは、ガレージ制御CTgの実行中に、車速Vに相関関係のある自動変速機24のAT出力回転速度Noが所定回転速度No1以上になった場合、ガタ詰め制御CTpを禁止して電動機MGのMG回転速度Nmが目標回転速度Nmf以上に上昇させるため、車両10のずり下がりが検出されると、ガタ詰め制御CTpを禁止して速やかに電動機MGのMG回転速度Nmが目標回転速度Nmf以上に上昇させられることでクリープトルクTcrpが発生させられる。従って、車両10のずり下がりが速やかに解消され、車両10のずり下がりによって運転者に与える違和感を抑制することができる。【選択図】図1
