Method for controlling the knocking of an internal combustion engine and a corresponding device

摘要

A method for knock control of an internal combustion engine, in which values are provided by an adaptive characteristics map for retarding an ignition angle is proposed, the values of the adaptive characteristics map being assigned to at least one operating parameter. Upon occurrence of a dynamic in the at least one operating parameter, a characteristics map value (wkra) is read from the adaptive characteristics map as a function of the instantaneous value of the at least one operating parameter. In this context, a previous value for the ignition angle adjustment (wkr(old)) is only replaced by the characteristics map value (wkra) when the amount of the difference between the previous value for the ignition angle adjustment (wkr(old)) and the characteristics map value (wkra) is less than a predefinable ignition angle difference (KRDWAA) (|wkr(old)-wkra|<KRDWAA).
