Hybrid vehicle and method for operating a hybrid vehicle

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.

A vehicle configuration, comprising:

• a hybrid vehicle having a combustion engine and an electric motor respectively for providing a torque for operating said hybrid vehicle;
• an exhaust gas system operatively connected to said combustion engine, said exhaust gas system having a catalytic converter system for at least one exhaust gas component;
• an energy storage device operatively connected to said electric motor for storing and returning electric energy;
• and
• a control device configured to ascertain at least one value of a catalytic converter activity, compare the value of the catalytic converter activity with at least one given limit value and provide a comparison result, and said control device being configured to control said electric motor to provide a torque addition in dependence on the comparison result and on a status value of said energy storage device in order to influence activity parameters of said catalytic converter system, the torque addition being selected from the group consisting of a motor torque addition and a generative torque addition.
