To provide a vehicle drive apparatus capable of reducing the occurrence of inertia shock upon clutch engagement.SOLUTION: In engagement control in which, after the determination of the engagement of a clutch WSC, the clutch WSC is brought from a release state into a complete engagement state (t3-t7), a control device executes an engagement preparation phase in which a torque capacity is not generated (t3-t6), and an actual engagement phase in which the torque capacity is generated, and the complete engagement state is reached (t6-t7). In the engagement control, in a case where a vehicle is traveling by the driving force of a rear motor drive-coupled to rear wheels, when the vehicle is in an acceleration state, the control device performs control so that the rotation speed of a rotary electric machine becomes higher than the rotation speed of a transmission member, and a differential rotation speed between the rotation speed of the rotary electric machine and the rotation speed of the transmission member becomes a first set value (t3-t7). When the vehicle is in a deceleration state, the control device performs control so that the rotation speed of the rotary electric machine becomes lower than the rotation speed of the transmission member, and the differential rotation speed becomes a second set value.SELECTED DRAWING: Figure 2
【課題】クラッチ係合時のイナーシャショックの発生を軽減可能な車両用駆動装置を提供する。【解決手段】制御装置は、クラッチWSCの係合判断後、クラッチWSCを解放状態から完全係合状態にする係合制御(t3-t7)において、トルク容量を生じない係合準備フェーズ(t3-t6)と、トルク容量を生じ、完全係合状態まで至る実係合フェーズ(t6-t7)とを実行する。制御装置は、係合制御の際、車両が後輪に駆動連結されたリヤモータの駆動力で走行している場合において、車両が加速状態であるときは、回転電機の回転速度を伝達部材の回転速度よりも高く、かつ、回転電機の回転速度と伝達部材の回転速度との差回転速度を第1設定値となるよう制御し(t3-t7)、車両が減速状態であるときは、回転電機の回転速度を伝達部材の回転速度よりも低く、かつ、差回転速度を第2設定値となるよう制御する。【選択図】図2
