ABSTRACT:
Driving forces of an engine and an electric motor can be transmitted to driving wheels, and the engine and the driving wheels can be mechanically connected and disconnected by a clutch. A vehicle ECU disengages the clutch and controls the motor to generate a required torque when an upper limit torque generable by the motor is equal to or above the required torque. On the other hand, the ECU engages the clutch and controls the engine and the motor in such a manner that a sum of the torques of the engine and the motor becomes the required torque when the upper limit torque is lower than the required torque. The ECU engages the clutch even if the upper limit torque is equal to or above the required torque when the revolution speed of the motor becomes equal to or above a predetermined revolution speed during traveling of the vehicle.
