Abstract
A method for adapting a lambda control of an internal combustion engine having an exhaust gas probe disposed in an exhaust gas duct of the internal combustion engine as part of an exhaust gas monitoring system, wherein the adaptation is carried out on the basis of a comparison between a modeled and a measured signal after a predetermined change in the fuel-air ratio of an air-fuel mixture supplied to said internal combustion engine has taken place and wherein the measured signal is an actual value of an output signal of the exhaust gas probe and the modeled signal is a modal value, which is derived from the air-fuel mixture supplied to said internal combustion engine through the use of an exhaust gas model.
