Abstract
A method for heating an exhaust system downstream from an internal combustion engine using an electrical heating device. The method includes an ascertainment of a current temperature in the exhaust system, an ascertainment of a current temperature of the electrical heating device and a fluid mass flow flowing through the electrical heating device, an ascertainment of a heating requirement based on the ascertained current temperature and a target temperature, a calculation of a required amount of heat depending on the heating requirement and an amount of energy required to heat up the electrical heating device, taking into account a heat input into the fluid mass flow to be expected at the ascertained current temperature of the electrical heating device, and a control of the electrical heating device to generate the calculated amount of heat. A computing unit and a computer program are also described.
