PROBLEM TO BE SOLVED: To suppress slip of a non-stage transmission at engine starting time.SOLUTION: A vehicle driving device includes: a travel mode control unit for switching between a first travel mode for travelling with power outputted at least by an internal combustion engine in a state where a non-stage transmission and driving wheels are in a fastened state by a fastening unit, and a second travel mode for travelling with power outputted by an auxiliary power output unit in a state where the non-stage transmission and the driving wheels are in a released state by the fastening unit; and a gear ratio control unit for determining a gear ratio of the non-stage transmission on the basis of a torque inputted in the non-stage transmission and the state of the non-stage transmission detected by a detection unit, when the travel mode control unit switches the second travel mode to the first travel mode.
【課題】エンジン始動時における無段変速機の滑りを抑制すること。【解決手段】締結部により無段変速機と駆動輪とが締結状態にされた状態で、少なくとも前記内燃機関により出力される動力で走行する第1の走行モードと、締結部により無段変速機と駆動輪とが解放状態にされた状態で、補助動力出力部により出力される動力で走行する第2の走行モードとを切り替える走行モード制御部と、走行モード制御部によって第2の走行モードから第1の走行モードに切り替えられるとき、無段変速機に入力されるトルクと、検出部により検出された無段変速機の状態とに基づいて無段変速機の変速比を決定する変速比制御部と、を備える車両駆動装置。【選択図】図1
