TH97152B - Impact judgment device and impact judgment method for internal combustion engines. - Google Patents

Abstract

The engine ECU unit manages the program, consisting of the procedure of detecting the dimensions. Of engine vibration (S102), engine vibration waveform detection by size (S104), computation of the relative coefficient K in case engine speed NE is less than the initial value NE (1) by Take the sum of the values for which each is determined by separating the positive references from the magnitude. On the shock waveform model is the area S of the shock waveform model and the correlation coefficient K is calculated in the case where the engine speed NE is not less than the initial NE (1) by using the area S of the model model. Total shock wave (S114) and determination of whether the shock was By using the K coefficient (S120, S124), the correlation coefficient K is calculated by dividing by the ground S per the sum of the differences that are each difference between sizes. On vibration waveforms and sizes on shock waveform models

1.The impact judgment device for the internal combustion engine consists of Crank angle detector (306) that detects the crank angle of such an internal combustion engine (100), an impact detector (300) that detects the magnitude of the vibration of the combustion engine. This magnitude is related to the crank angle, and the functional unit (200), whereby the working unit (200) detects the waveform of the vibration during one of the Corner
