Abstract
A method for computing an ignition angle of an internal combustion engine as a function of the operating conditions of the engine and knock signals K, which indicate knocking combustion in the engine. If knock occurs, the ignition angle is retarded. If knock stops for a first period, the ignition angle is advanced again. Advance of the ignition angle is limited on the basis of the first period. If knock stops for a second period, which exceeds the first period, the ignition angle is further advanced.
