Zusammenfassung:	To provide a method for operating a hybrid drive train allowing dynamic operation capable of inhibiting emission of pollutants.SOLUTION: A method includes: determining an actual state vector of an internal combustion engine of a hybrid drive train (V10); determining a target power of the internal combustion engine (V20); determining a target fuel mass flow for the internal combustion engine as a function of the target power of the internal combustion engine (V30); 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 (V40); determining a target fuel mass flow by forming a minimum value as a function of the target fuel mass flow and the limit fuel mass flow (V50); and designing the target fuel mass flow at the internal combustion engine (V60).SELECTED DRAWING: Figure 2 【課題】汚染物質の排出を抑制することができるダイナミックな運転が可能なハイブリッドドライブトレインの運転方法を提供する。【解決手段】ハイブリッドドライブトレインの内燃機関の実際の状態ベクトルを決定し（Ｖ１０）、内燃機関の目標出力を決定し（Ｖ２０）、内燃機関の目標出力を関数として内燃機関の目標燃料質量流量を決定し（Ｖ３０）、排気限界値、目標燃料質量流量および内燃機関の実際の状態ベクトルを関数として内燃機関の限界燃料質量流量を決定し（Ｖ４０）、目標燃料質量流量および限界燃料質量流量を関数として最小値を形成し目標燃料質量流量を決定し（Ｖ５０）、内燃機関に目標燃料質量流量を設計する（Ｖ６０）。【選択図】図２
