Abstract

A method for determining an exhaust gas temperature of an internal combustion engine, which is performed by measuring a lambda value of the exhaust gas of the internal combustion engine and calculating a calculated exhaust gas temperature as a function of the measured lambda value, and comparing the calculated exhaust gas temperature with a measured exhaust gas temperature and adapting a function used for the calculation as a function of the comparison.
