Zusammenfassung:	The invention relates to a method for detecting a knocking occurrence during a switching process between operating modes of an internal combustion engine (2). The method comprises the following steps: - recording a course of an acoustic signal (ikr) of an internal combustion engine (2); - determining a reference level (rkr) of the acoustic signal which corresponds to a specification of a basic engine noise according to the course of the acoustic signal (ikr); and - detecting a knocking occurrence according to the reference level (rkr); wherein the reference level (rkr) of the acoustic signal is determined according to the switching process between the operating modes of the internal combustion engine (2).
