ABSTRACT:
A hybrid vehicle is driven by one or both of an engine and a drive motor. The engine is started by a power generating motor, 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, a revolution speed of the power generating motor is controlled based on that of the drive motor. After a 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.
