Abstract:
1. A method for operating a hybrid vehicle, which comprises: providing a hybrid vehicle having a combustion engine and an electric motor respectively for providing a torque for operating the hybrid vehicle; providing an exhaust gas system for the combustion engine, the exhaust gas system having a catalytic converter system for at least one exhaust gas component; providing an energy storage device for storing and returning electric energy; using a model having values of a load-rotational speed operating point shift of the combustion engine correlated with at least one of values of an exhaust gas mass flow and values of a raw emission of at least one exhaust gas component; and taking into account the values of the load-rotational speed operating point shift of the combustion engine when setting a torque output of the electric motor in order to reduce a total energy expenditure when operating the hybrid vehicle.
