A vehicle control part includes: a vehicle stop determination part for determining whether or not the vehicle is stopped; a clutch control part for disengaging the clutch when stop of the vehicle is determined; a motor control part for driving the motor so as to drive the oil circulation part after the clutch is disengaged; and a motor magnet temperature estimation part for detecting an inducted voltage generated by drive of the motor, and estimating a magnet temperature of the motor from the detected induced voltage of the motor. The motor control part continues the drive of the motor when the estimated magnet temperature of the motor is higher than a predetermined reference temperature at which the motor needs to be cooled, and stops the drive of the motor when the magnet temperature of the motor is equal to or lower than the predetermined reference temperature.
