摘要： Out of synthesized waveforms of vibrations in a first frequency band A to a third frequency band C, a knock magnitude N is calculated by using a portion β having an integrated value greater than a reference magnitude in a knock region but not using a portion having an integrated value greater than the reference magnitude out of the knock region (i.e., a region obtained by excluding the knock region from a knock detecting gate). In a case where knock magnitude N is greater than a determination value V(KX), it is determined that knocking occurs. In contrast, in a case where knock magnitude N is not greater than determination value V(KX), it is determined that no knocking occurs.

摘要： A band pass filter processing extracts the vibration component (frequency component) of the 1st to the 4th order frequency band from the output of the knock sensor. A primary frequency band is established as the frequency band containing the fundamental frequency (primary resonance frequency) which is the lowest frequency of the knocking vibration frequencies. The 2nd to the 4th order frequency band is established as the frequency band containing the 2nd to the 4th order resonance frequency. Based on the vibration strength of the primary frequency component, the comparison result between the composite vibration waveform which compounded the 1st to the 4th order frequency component and the ideal knock waveform, and the vibration strength of the summation of the 1st to the 4th order frequency component, the noise and knocking are distinguished from each other with sufficient accuracy.

摘要： An engine ECU executes a program including a step of setting a search range of the crank angle of a peak value P that is the largest integrated value in a vibration waveform of an engine detected by calculating integrated values that are integrals of output voltage values of a knock sensor for every five degrees of a crank angle such that the search range may include the crank angle increasing with increase in engine speed NE, and a step of detecting the crank angle of the largest integrated value in the search range, and setting the detected crank angle as the crank angle of peak value P in the vibration waveform. At the crank angle based on the crank angle of peak value P, the vibration waveform is compared with a knock waveform model.
