ABSTRACT:
The method includes sampling a sensor signal of at least one knocking sensor after amplification and preparation at a predetermined frequency within a measurement window being predetermined for each firing cycle, to form sampled values. A knocking value is determined from a mean value of a predetermined number of greatest sampled values. A noise value is ascertained by forming a sliding mean value from a predetermined number of previous knocking values. An actual noise value is formed from the cylinder-selective noise values. A command noise value being dependent on at least one noise-determining engine parameter is read out of a performance graph. A difference between or a ratio of the actual noise value and the command noise value is formed. The comparison is processed in a controller to produce a correction factor. The correction factor is linked with a pilot value being read out of a pilot performance graph and being dependent on at least one noise-determining engine parameter, to produce a total amplification factor for the sensor signal.
