Title: METHOD FOR THE OPERATION OF A HYBRID VEHICLE
Abstract:
The invention relates to a method for operating a hybrid vehicle, comprising a start-stop function, an internal combustion engine, a gearbox coupled thereto by means of an input shaft, an electric engine coupled to the input shaft, an output shaft of the gearbox at least indirectly coupled to the driven wheels, an electric energy storage device, a gearbox control device, during the start-stop function, the internal combustion engine is coupled at the beginning of a stop phase and is restarted at the end of the stop phase, and a brake with which the hybrid vehicle is stopped at least during the stop phase, a start function with which the internal combustion engine is started by means of the electric engine at the end of the stop phase. The claimed method is characterised in that the gearbox as well as the electric engine is controlled by the gearbox control device, the driving of the hybrid vehicle is controlled by the gearbox control device after a stop phase, wherein the moment in time for releasing the brake is predetermined by the gearbox control device, the moment in time being determined in the gearbox control device in accordance with the presently available torque on the output shaft and at least based on the inclination of the carriageway.
