At this time, the engine vibration is hardly reduced by the engine connecting / disconnecting clutch K0. However, as the required driving force Tr increases, the engine torque Te increases and the engine vibration also decreases. Therefore, even if the engine connecting / disconnecting clutch K0 is engaged, the engine vibration is reduced by the increase of the engine torque Te, so that the vibration transmitted to the drive wheels 34 is reduced.
