<p>The present invention implements a vehicle driving device which can effectively suppress the occurrence of a failure of a one-way clutch while suppressing increases in manufacturing cost and weight. A vehicle driving device is provided with an input member which is drive-connected to an internal combustion engine, an output member (O) which is drive-connected to a wheel, a first rotating electric machine (MG1), a second rotating electric machine, a differential gear, and a controller. The vehicle driving device is provided with a one-way clutch which restricts the negative rotation of an input rotational element (Ei) of the differential gear to which the input member is drive-connected. The controller is provided with a rotational change detection unit which detects an output rotational sudden change state in which the rotational acceleration of the output member (O) becomes a predetermined value (At) or more, and a restriction avoidance control unit which, when the output rotational sudden change state is detected in a low rotational state in which the rotational speed of the input rotational element (Ei) becomes less than a control threshold value (Nt), performs restriction avoidance control for controlling the rotational speed of the first rotating electric machine (MG1) such that the rotational speed of the input rotational element (Ei) becomes the control threshold value (Nt) or more.</p> |
