ABSTRACT:
A method and apparatus for operating a hybrid car which includes an electric motor for driving the car, and an internal combustion engine for power generation. At least first and second vehicle operating parameters, such as accelerator pedal depression depth and actual vehicle velocity, are detected. Based on these vehicle operating parameters, a controller controls the electric motor. From these vehicle operating parameters, a vehicle operating state is determined. The charge state of a battery, which supplies electric power to the electric motor, is also detected. Based on the charge state and the vehicle operating state, a target engine operating state is set for the internal combustion engine. The target engine operating states are determined so that low fuel consumption is ensured. The controller then controls the internal combustion engine to achieve the target engine operating state.
