A crankshaft of an engine, an output shaft of a first electric motor, and an output shaft of a second electric motor are directly or indirectly connected to each other mechanically. When the engine is started, a vibration reduction torque is caused to act on the crankshaft that is set in the form of a periodic torque based on the crank angle, so that torque pulsation of the engine is suppressed. The output torque of the first electric motor is controlled in accordance with the sum of a motoring torque and a part of the vibration reduction torque. The output torque of the second electric motor is controlled in accordance with the sum of its essential output torque for causing the vehicle to travel and a torque for compensating for a shortage of the vibration reduction torque that occurs because a part of the vibration reduction torque is output from the first electric motor.
