Abstract

A method for setting operating states of an internal combustion engine, in particular an internal combustion engine of a hybrid drive. In addition to the internal combustion engine, the hybrid drive includes at least one electric drive, a hybrid coordinator and a control unit assigned to the internal combustion engine in which functions are implemented. The functions request operating states favorable to their running ability from the hybrid coordinator which performs a commensurate modification of the distribution of power between the internal combustion engine and the at least one electric drive.
