Inventor: TSUCHIYA YUKI
IPC: F02D45/00
Filed: 2020-02-26
Abstract: To prevent that a characteristic of a vibration waveform generated by a plurality of noises is erroneously determined as a characteristic of one knock waveform, and a characteristic of a vibration waveform generated by both the noises and the knock is erroneously determined as the characteristic of one knock waveform.SOLUTION: In the followings, waveforms of a series of prescribed vibrations included in a vibration waveform are set as "individual waveforms Wo". A finish determination part recognizes a boundary between the individual waveforms Wo by determining a finish part of each individual waveform Wo. A characteristic extraction part 33 extracts characteristics Ps, Pm and Pe of the individual waveforms Wo on the basis of the recognition of the boundary. A knock determination part 35 determines whether or not the characteristic is a characteristic of the knock waveform with respect to the individual waveforms Wo whose characteristics are extracted by the characteristic extraction part 33. Then, on condition that the characteristic of any of the individual waveforms Wo is determined to be the characteristic of the knock waveform, the knock determination part determines the existence of a knock.SELECTED DRAWING: Figure 7
