摘要： PROBLEM TO BE SOLVED: To accurately determine whether knocking occurs or not.
SOLUTION: This knocking determining device calculates a difference between a logarithmic value for the strength of a vibration waveform and a logarithmic value for the strength of a predetermined knocking waveform model or multiplies a difference between the strength of the vibration waveform and the strength of the knocking waveform model by a reciprocal number of the strength of the knocking waveform model to calculate the difference between the strength of the vibration waveform and the strength of the knocking waveform model while applying greater weighting thereto as the strength is smaller. In accordance with the difference between the strength of the vibration waveform and the strength of the knocking waveform model, calculated while applying greater weighting thereto as the strength is smaller, it determines whether knocking occurs or not.
