Abstract
Proposed is a method for adjusting an adaptive characteristics map of an adaptive engine-knock control system and a method for adaptively controlling engine knock, the adaptive characteristics map being defined by at least one operating parameter, the adaptive characteristics map for each operating-parameter range being made up of a precontrol component that characterizes the ambient conditions, and a residual component that results from the engine-knock control, the value of the adaptive characteristics map for each operating-parameter range being given by the sum of the precontrol component corresponding to the specific operating-parameter range, and the residual component corresponding to the specific operating-parameter range. In this context, the adjustment of the adaptive characteristics map is carried out by initially determining if ambient conditions have changed, and by subsequently ascertaining a new precontrol component as a function of the changed ambient conditions for each operating-parameter range, if the ambient conditions have changed, or by holding the precontrol component constant for each operating-parameter range, if the ambient conditions have not changed.
