Abstract

A method for the adaptive knock control of an internal combustion engine serves for shifting the ignition angle of an internal combustion engine in the retard direction when knocking occurs and for subsequently carrying out a return of the ignition angle in the advance direction. At the same time, the internal combustion engine is to have sub-divided operating ranges, and a value of an ignition-angle retard, determined in a range during operation, is always stored when this range is left. At the same time, in particular an average of all the ignition angles outputted in a range or a retard value plotted by a digital low-pass filter is to be stored.
