Abstract
When a shift lever is in a parking position, a rotation restriction index Jmis set based on a drive state of an engine or a first motor (S, S, S, and S). A current value based on the rotation restriction index Jmis set to a current command of the d axis in an electric angle when motoring of the engine in a stop state is started and a second motor is controlled such that the magnetic field direction of a stator of the second motor is fixed. This method can appropriately prevent a power shaft from rotating.
