description 2. Die Erfindung betrifft ein Verfahren zum Betrieb eines Hybrid-Antriebsstrangs, umfassend die Schritte: Ermitteln eines Ist-Zustandsvektors einer Brennkraftmaschine des Hybrid-Antriebsstrangs (V10); Ermitteln einer Ziel-Leistung der Brennkraftmaschine (V20); Bestimmen eines Ziel-Kraftstoffmassenflusses für die Brennkraftmaschine in Abhängigkeit der Ziel-Leistung der Brennkraftmaschine (V30); Bestimmen eines Grenz-Kraftstoffmassenflusses der Brennkraftmaschine in Abhängigkeit eines Emissionsgrenzwertes, des Ziel-Kraftstoffmassenflusses und des Ist-Zustandsvektors der Brennkraftmaschine (V40); Bestimmen eines Soll-Kraftstoffmassenflusses durch Minimalwertbildung in Abhängigkeit von Ziel-Kraftstoffmassenfluss und Grenz-Kraftstoffmassenfluss (V50); und Einstellen des Soll-Kraftstoffmassenfluss an der Brennkraftmaschine (V60). 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.
