A method for operating a hybrid drive train includes ascertaining an actual state vector of an internal combustion engine of the hybrid drive train; ascertaining a target power of the internal combustion engine; determining a target fuel mass flow for the internal combustion engine as a function of the target power of the internal combustion engine; determining a limit fuel mass flow of the internal combustion engine as a function of an emission limiting value, the target fuel mass flow, and the actual state vector of the internal combustion engine; determining a setpoint fuel mass flow by forming a minimum value as a function of the target fuel mass flow and the limit fuel mass flow; and setting the setpoint fuel mass flow at the internal combustion engine.
