A target drive torque is calculated based on a detected value for vehicle speed and a detected value for an accelerator pedal depression amount. A generator torque is calculated for a motor(1,4) based on a battery SOC. An engine(2) is controlled to a torque value which achieves a target drive torque and a generator torque as a target engine torque. The motor(1,4) is controlled to a value which is the difference of a target drive torque and an engine torque estimation value as a target motor torque. In this way, a required generator amount may be achieved under steady-state conditions and it is possible to satisfy charge conditions of the battery(15). In addition, required drive force by the driver can be achieved during transition running and responsive acceleration and deceleration can be performed.
