Zusammenfassung:	To suppress a shift shock when executing a torque reduction by fuel cut at an upshift in a hybrid vehicle equipped with an automatic transmission.SOLUTION: In a hybrid vehicle equipped with an automatic transmission, a control apparatus for controlling an engine and an MG performs: reducing input shaft torque of the automatic transmission by regenerative toque generated by the MG at a starting period of inertia phase when up-shifting the transmission (clock time t3); and then executing a fuel cut of the engine 10 (clock time t4). When returning from the engine fuel cut, the control apparatus reduces the regenerative torque of the MG on the basis of a given returning slope.SELECTED DRAWING: Figure 2 【課題】自動変速機を備えたハイブリッド車両において、アップシフト時に燃料カットによるトルクダウンを実行する際の変速ショックを抑制する。【解決手段】自動変速機を備えたハイブリッド車両において、エンジンおよびＭＧを制御する制御装置は、自動変速機のアップシフト時、イナーシャ相の開始時期に、ＭＧが発生する回生トルクによって、自動変速機の入力軸トルクを低減し（時刻ｔ３）、その後、エンジン１０の燃料カットを実行する（時刻ｔ４）。制御装置は、エンジンの燃料カットからの復帰時、所定の復帰勾配に基づいてＭＧの回生トルクを減少させる。【選択図】図２
