Abstract
The second clutch is caused to transition to an engaged state after setting the second clutch in a slip state when the vehicle starts in the hybrid start mode, the temperature of a magnet of the electric motor is estimated based on the temperature of the hydraulic oil and an operating condition of the electric motor when the second clutch is controlled to be in the slip state; and an output torque and a lower limit rotation speed of the electric motor is restricted and reduced when the estimated temperature of the magnet exceeds a restrictive temperature.
