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.

1. A method for setting an operating state of an internal combustion engine of a hybrid drive system, the hybrid drive system further including at least one electric drive, a hybrid coordinator, a control unit for the internal combustion engine, the control unit including multiple functions, the method comprising: generating and transmitting, by each function, information regarding operating readiness of the respective function and associated possible operating states of the internal combustion engine in which the respective function is able to be executed;selecting, by a scheduler of the functions, a function which has operating readiness and has the highest priority among the multiple functions; andif at least one of the possible operating states associated with the selected function is able to be implemented by the hybrid coordinator, the hybrid coordinator performing a modification of a distribution of power between the internal combustion engine and the at least one electric drive to operate the internal combustion engine at the at least one of the possible operating states. 2. The method as recited in claim 1, wherein during the modification of the distribution of power between the internal combustion engine and the at least one electric drive, a requested transmission output torque is generated and a requested vehicle speed is maintained. 3. The method as recited in claim 1, wherein each of the functions sends its operating readiness to the scheduler via a signal at each specific possible operating point or operating range. 4. A method for setting an operating state of an internal combustion engine of a hybrid drive system, the hybrid drive system further including at least one electric drive, a hybrid coordinator, a control unit for the internal combustion engine, the control unit including multiple functions, the method comprising: generating and transmitting, by the hybrid coordinator, information regarding possible operating states or operating ranges of the internal combustion engine to the control unit of the internal combustion engine or a scheduler of the functions;determining, by each of the functions or by the scheduler of the functions, operating readiness of each function for the possible operating states or the possible operating ranges of the internal combustion engine;selecting, by the scheduler of the functions, a function which has operating readiness and has the highest priority among the multiple functions, wherein the scheduler sends at least one of possible operating state and possible operating range associated with the selected function to the hybrid coordinator; andperforming, by the hybrid coordinator, a modification of a distribution of power between the internal combustion engine and the at least one electric drive to operate the internal combustion engine at the at least one of the possible operating state and the possible operating range associated with the selected function. 5. The method as recited in claim 4, wherein a maximum time duration for at least one of an operating state and an operating range, of the internal combustion engine is determined in the hybrid coordinator, the maximum time duration being sent either to the control unit for the internal combustion engine or to the scheduler of the functions. 6. The method as recited in claim 4, wherein in the event of a modification of the driving state, the hybrid coordinator adjusts the possible operating states of the internal combustion engine, and a change occurs between at least one of various operating states, thrust, idling, normal operation, engine stop, and operating points of the internal combustion engine, without changing the transmission output torque and without changing a transmission output rotational speed.
