A change shock caused in mutually shifting a vehicle between a motor and engine drive states is prevented. A hybrid vehicle is driven by one or both of an engine (11) and a drive motor (12). The engine is started by a power generating motor (21), and power generated by the engine is supplied to a battery. An engine-power transmission path is provided with a coupling for being shifted to a connection state of transmitting engine power to drive wheels and a disconnection state of cutting off the transmission. In connecting the coupling while the drive motor is driven and transmitting engine torque, the revolution speed of the power generating motor (21) is controlled based on that of the drive motor (12). After the revolution speed of an input-side shaft of the coupling is synchronized with that of an output-side shaft, the coupling is connected. After the coupling is connected, torque of the drive motor and engine is controlled based on required torque of the vehicle. |
