Abstract
A method and a device are provided for knock recognition of an internal combustion engine, which device Fourier-transforms, weights in frequency-dependent fashion, and sums a signal of a knock sensor in order to produce a first knock signal. Here, from a multiplicity of first knock signals, a concentration point of the multiplicity of the first knock signals is determined, and a first offset value is subtracted from the first knock signal in order to form a second knock signal, the first offset value being ascertained from the concentration point of the multiplicity of the first knock signals, and a second knock signal that has a value below zero being set to the value zero. The further-processed second knock signal is then evaluated as knocking or non-knocking.
