Abstract
In a method for operating a hybrid vehicle, which includes an internal combustion engine and an electric machine as the propulsive drive, the electric machine operates in both motor and generator modes. Furthermore, there is an accumulator device, such as a capacitor assembly, for storing electric energy. The aim is to provide a method that guarantees an improved start-up operation of a hybrid motor vehicle in terms of fuel consumption and emission. This is achieved in that in the start-up operation the torque required on the basis of the request of the driver to drive the vehicle is divided between the internal combustion engine and the electric machine, as a function of the existing operating parameters of the vehicle.
