Abstract

The invention relates to a method for operating a hybrid drive, especially a hybrid drive for a motor vehicle, comprising at least one electric engine and at least one internal combustion engine as driving engines. According to said method, the hybrid drive generates a required nominal drive torque and a nominal power of the electric engine is maintained. The method comprises the following steps: a plurality of characteristic diagrams are generated, in which a first driving torque of the electric engine and a second driving torque of the internal combustion engine are respectively allocated to a hybrid drive rotational speed and a hybrid driving torque, taking into account at least one selectable criterion; one of the characteristic diagrams is selected, in which the nominal power is at least maintained; and the hybrid drive is operated by means of the driving torques resulting from the selected characteristic diagram.
