Beschreibung
Zusammenfassung:	The invention relates to a motor vehicle having: an internal combustion engine (13); an exhaust section (20) in which exhaust gas of the internal combustion engine (13) discharged from the motor vehicle flows during operation of the motor vehicle and which has a catalytic converter (12) configured to purify the exhaust gas; an electric heating element (11) configured to heat the catalytic converter (12); a first temperature sensor (18) configured to measure a first temperature (T1) of the exhaust gas upstream of the electric heating element (11); and a second temperature sensor (19) configured to measure a second temperature (T2) of the exhaust gas downstream of the electric heating element (11); and a temperature controller (17) in which an observer (30) is implemented, which is configured to model the temperature (TH) of the electrical heating element (11) using the first temperature (T1) and the second temperature (T2) when the mass flow of the exhaust gas is below a limit mass flow, in which the temperatu
