PROBLEM TO BE SOLVED: To provide a driving device for a vehicle, which in the vehicle capable of switching a two-wheel driving state to a four-wheel driving state by engaging an engagement device, can improve responsiveness of the engagement device under engagement control.SOLUTION: A driving device for a vehicle comprises main drive wheels driven by an engine, secondary drive wheels driven by a third rotary machine MG3, an inverter making the third rotary machine MG3 drive, an engagement device selectively engaging or releasing the third rotary machine MG3 and the secondary drive wheels, and control means making the engagement device engage when a vehicle state is outside of a release region. The control means sets a shutdown region in the release region for putting the inverter in a shutdown state to stop the third rotary machine MG3, and when the vehicle state is outside of the shutdown region, restores the inverter from the shutdown state before an engagement request to make the third rotary machine MG3 drive.SELECTED DRAWING: Figure 4
【課題】係合装置を係合することで二輪駆動状態から四輪駆動状態へと切り替えることができる車両において、係合装置の係合制御時における応答性を向上させることができる車両用駆動装置を提供する。【解決手段】車両用駆動装置は、エンジンによって駆動される主駆動輪と、第3回転機MG3によって駆動される従駆動輪と、第3回転機MG3を駆動させるインバータと、第3回転機MG3と従駆動輪とを選択的に係合または解放させる係合装置と、車両状態が解放領域外の場合に係合装置を係合させる制御手段と、を備え、制御手段が、インバータをシャットダウン状態にして第3回転機MG3を停止させるシャットダウン領域を解放領域内に設定し、車両状態がシャットダウン領域外の場合、係合要求前にインバータをシャットダウン状態から復帰させて第3回転機MG3を駆動させる。【選択図】図4
