Abstract: A shock when switching between the motive force of a motor and an engine is avoided. A first electrical motor mechanically connected to an engine and a second electrical motor connected mechanically to an engine through a clutch is provided. In a hybrid vehicle in which motive force is transmitted to the drive wheels through a transmission from a second electric motor, it is decided whether or not to release the clutch based on the vehicle speed detected value and the required motive force detected value. The engine output at that time is estimated. Thus if it is decided to release the clutch, the output of the second electrical motor is controlled so that the generated torque corresponds to said estimated output. The output of the first electrical motor is controlled so that the torque generated by the second electrical motor is absorbed. Hence the sum of both outputs is approximately 0. In this way, there is no shock when the clutch is released and the switch is made from an engine brake due to the engine to a generator brake due to the second electrical motor and driving performance is enhanced.
