PROBLEM TO BE SOLVED: To achieve rapid down shifting of an automatic transmission while maintaining energy efficiencies excellently.SOLUTION: The vehicular driving device comprises: an engine 1; an automatic transmission 4; a power connection/disconnection clutch 2 for connecting and disconnecting an output shaft of the engine to and from an output shaft of the automatic transmission; a regeneration device linked to the input shaft of the automatic transmission; a first transmission control portion 52 that releases the power connection/disconnection clutch; an engine control portion 51 that increases synchronous rotation speed of the output shaft of the engine up to the synchronous rotation speed after releasing the power connection/disconnection clutch; a regeneration control portion 53 that imparts positive torque to the input shaft of the automatic transmission by switching a mode of the regeneration device to a driving mode while releasing the power connection/disconnection clutch; and a second transmission control portion 52 that switches a fastening pattern of a friction fastening element of the automatic transmission in response to increase of the rotation speed of the output shaft of the engine up to the synchronous rotation speed, and fastens the power connection/disconnection clutch.SELECTED DRAWING: Figure 4

    【課題】エネルギー効率を良好に維持しながら自動変速機の迅速なダウンシフト変速を実現する。【解決手段】車両用駆動装置は、エンジン1と、自動変速機4と、エンジンの出力軸と自動変速機の出力軸とを断接する動力断接クラッチ2と、自動変速機の入力軸に連係された回生装置と、自動変速機のダウンシフト変速時に、動力断接クラッチを解放する第1変速制御部52と、動力断接クラッチの解放以後に、エンジンの出力軸の回転数を同期回転数に向けて上昇させるエンジン制御部51と、動力断接クラッチの解放期間中に回生装置のモードを駆動モードとして自動変速機の入力軸に正トルクを付与する回生制御部53と、エンジンの出力軸の回転数が同期回転数まで上昇するのに応じて、自動変速機の摩擦締結要素の締結パターンを切り替えるとともに、動力断接クラッチを締結させる第2変速制御部52とを備える。【選択図】図4
