Abstract
A method for automatic lambda control of an internal combustion engine, in which, upon detection of a predetermined operating state of the internal combustion engine, a calibration factor (KAL) is determined and in which, during the operation of the internal combustion engine, a lambda measuring signal (iP) is corrected by the calibration factor (KAL) and is set as the actual lambda value (Lam(IST)) for the automatic lambda control of the internal combustion engine. The predetermined operating state is recognized when an engine coastdown is initiated.
Claims13
A method for automatic lambda control of an internal combustion engine, comprising the steps of:
- determining a calibration factor (KAL) upon detection of a predetermined operating state of the internal combustion engine;
- correcting a lambda measuring signal (iP), during operation of the internal combustion engine, by the calibration factor (KAL);
- and setting the signal as an actual lambda value (Lam(IST)) for the automatic lambda control of the internal combustion engine, wherein the predetermined operating state is recognized when an engine coastdown is initiated.
