The present invention is proposed to avoid the generation of shocks when the output of an engine is switched with that of an electric motor connected by a clutch. The invention comprises a first electric motor connected mechanically to an engine and a second electrical motor connected mechanically through a clutch to an engine. The drive force is transmitted to the drive wheel through a transmission from the second electric motor. It is decided whether or not to connect the clutch on the basis of driving conditions. When it is decided to connect the clutch, the engine is controlled so that the output of the engine meets the required force. The first electric motor functions as an electric generator so that the rotation speed of the engine reaches a target rotation speed. When the engine is rotating at a target rotation speed, the clutch is connected. In this way, shocks are avoided when the clutch is connected and improved driving performance is realized.
