ABSTRACT:
An operating method for a hybrid car which has an electric motor for driving the vehicle and an internal combustion engine for power generation. Using an operational expression including a motor output correction factor whose value is variably adjusted to different values depending on whether the engine is operated for battery charging or the engine is stopped, a required motor current supply that matches the vehicle operating state represented by an actual vehicle speed and an accelerator pedal depression depth is calculated, and the motor current supply is controlled in accordance with the result of the calculation. Consequently, the cruising range of the hybrid car is increased, and also the power performances and exhaust gas characteristics of the hybrid car are improved.
