A hybrid vehicle controls operation of an engine, a generator and a motor to retain driving comfort. The engine and the generator are connected through a planetary gear unit to a drive shaft, and the output of the engine 1 is split between the generator and the drive shaft. An engine control system controls the output of the engine by controlling the degree of throttle opening &thetas; responsive to engine speed. A generator control system controls electric current IG of the generator in order to achieve a target rotational speed NG*. A vehicle control system supplies a motor control system with a torque signal TM* based on the degree of accelerator opening alpha and vehicle speed V, and computes a value for compensatory torque DELTA TM from values for generator rotational speed NG and generator torque TG which are supplied from the generator control system. The motor control system controls electric current IM to the motor in accordance with the values for torque TM* and the compensatory torque DELTA TM. <IMAGE> |
