Abstract
A method () for heating an exhaust system () downstream of an internal combustion engine () by means of an electric heating device (). In one example, the method includes determining a current temperature (t_EHC, t_EHC{circumflex over ( )}Us, t_Cat) in the exhaust system (), determining a heating demand (t_EHC{circumflex over ( )}Des) based on the determined current temperature (t_Cat) and a target temperature, calculating a required amount of heat (Pwr{circumflex over ( )}Des) on the basis of the heating demand and an amount of energy required to heat the electric heating device (), and controlling (Pwr{circumflex over ( )}Req) the electric heating device () to generate the calculated amount of heat.
