Abstract
In response to a starting instruction of an engine at a gearshift position of a gearshift lever set to a parking position, a motor is controlled to form a fixed magnetic field on a stator of the motor at the level that is capable of preventing rotation of a rotating shaft against a torque applied to the rotating shaft within magnitude less than or equal to magnitude of a rotation restriction control torque based on a temperature of the motor and a discharge power from the battery, a motor is controlled to perform the motoring of the engine while the motor outputs a torque that makes a torque applied to the rotating shaft less than or equal to magnitude of the rotation restriction control torque, and the engine is controlled to be started with the motoring.
