VEHICULAR DRIVING DEVICE

To provide a vehicular driving device which can reduce differential rotation of a pair of engagement elements in an engagement device for connecting and disconnecting power transmission between an input member drive-connected to an internal combustion engine and a differential gear mechanism when starting the internal combustion engine in a configuration provided with the differential gear mechanism having three rotation elements.SOLUTION: A control device can execute first transfer control when transferring from a first mode to a second mode. The first transfer control includes: first control in which a second engagement device for connecting and disconnecting power transmission between two rotation elements of three rotation elements in a differential gear mechanism is changed from a direct coupling engagement state to a slip engagement state while maintaining a transmission mechanism in a state for performing power transmission; second control in which a first engagement device is changed from a release state to a slip engagement state after the first control; and third control in which an internal combustion engine is started by torque transmitted to the internal combustion engine from the differential gear mechanism side through the first engagement device in the slip engagement state while maintaining the second engagement device in the slip engagement state after the second control.SELECTED DRAWING: Figure 6 【課題】３つの回転要素を有する差動歯車機構を備えた構成において、内燃機関を始動させる場合に、内燃機関に駆動連結される入力部材と差動歯車機構との間の動力伝達を断接する係合装置の一対の係合要素の差回転を低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、第１モードから第２モードに移行する場合に、第１移行制御を実行可能であり、第１移行制御は、伝達機構が動力伝達を行う状態に維持しつつ、差動歯車機構の３つの回転要素のうちの２つの間の動力伝達を断接する第２係合装置を直結係合状態からスリップ係合状態に変化させる第１制御と、第１制御の後、第１係合装置を解放状態からスリップ係合状態に変化させる第２制御と、第２制御の後、第２係合装置をスリップ係合状態に維持しつつ、スリップ係合状態の第１係合装置を介して差動歯車機構の側から内燃機関に伝達されるトルクにより内燃機関を始動させる第３制御と、を含む。【選択図】図６
