PROBLEM TO BE SOLVED: To suppress occurrence of shock even when a clutch for disengaging a motor is unintentionally engaged with the motor.SOLUTION: A vehicle comprises: an engine 10; a motor generator 20 connected to a rotating shaft provided among the engine and driving wheels; a mechanical oil pump MOP connected to the rotating shaft 35; a clutch for disengaging a motor K2 provided between the rotating shaft and the motor generator; and an ECU 100 controlling the motor generator. The clutch for disengaging the motor is constituted so as to become in an engagement state when a hydraulic pressure supplied from the MOP is less than a predetermined release hydraulic pressure and to become in a release state when the hydraulic pressure supplied from the MOP is equal to the release hydraulic pressure or more. The ECU executes synchronization control for synchronizing a rotational speed of the motor generator with a rotational speed of the rotating shaft when there is a possibility that an output hydraulic pressure of the MOP is reduced to be less than the release hydraulic pressure during an engine travel mode in which the clutch for disengaging the motor is brought into the release state and the vehicle travels by power of the engine.SELECTED DRAWING: Figure 1
