Abstract: In a case where an operation to a non-parking operation position is performed at the time when an engine stops at a parking position, an electronic control unit executes two controls, i.e., a change to a non-parking position and starting of the engine, simultaneously. At this time, in a case where the operation to the non-parking operation position is performed at the time when the engine is stopped at the parking position by stop-start system, a deceleration start timing of an electric actuator is made earlier in comparison with a case where the operation is performed at a time different from the above. Accordingly, even in a state where a voltage of the electric actuator is decreased, a motor rotation position can be easily stopped at a non-p target rotation position.

The overall loss L during execution of intermittent boosting is calculated from the losses L1 and L2 of the motors and the loss LC of the boost converter during execution of intermittent boosting. A minimum loss-time boosting voltage Vtmp at which the overall loss L provides a minimum loss Ltmp is set to a target voltage VH*. The boost converter is then controlled in a control state corresponding to the minimum loss-time boosting voltage Vtmp.
