Abstract: A method for controlling knocking of an internal combustion engine in which a knocking signal and a combustion signal are formed by directing vibrations detected by a vibration sensor through a primary filter circuit including a combustion filter circuit and a knocking filter circuit. The combustion filter circuit and knocking filter circuit each include a time gate and a filter. A ratio of a representative value of the knocking signal to a representative value of the combustion signal is obtained and used to decide whether knocking is occurring. The output voltage of control signals generated based on the decision that knocking is occurring may be varied as a function of the strength of the knocking and/or the frequency of the knocking.
