Abstract:
The invention relates to a method for determining a gas concentration in a measuring gas by means of a gas sensor. In a first mode of operation of an internal combustion engine, in which the gas concentration in the measuring gas is known, a gas concentration signal and a pressure signal are detected. A compensation parameter of the gas sensor is determined from said signals. The thus determined compensation parameter is taken into account in at least one of the two modes of operation of the internal combustion engine for determining the gas concentration.
