Structure and Diagnosis Method of Early Damage Detection System of Automobile Transmission Parts

摘要

The present invention relates to a structure and a diagnosis method of a failure early diagnosis system for a vehicle transmission component, comprising: a dynamometer drive signal output step; Comparing the driving time of the dynamometer of the dynamometer with the transmission full test time; Stopping the output of the drive signal when the drive time is equal to the set time; Converting a signal generated from a transmission during a driving time of the dynamometer into a frequency signal and reading a frequency; A first frequency comparing step of searching for a frequency corresponding to the magnitude of the reference damage frequency among the read frequencies and comparing whether there is a frequency matching the magnitude of the reference damage frequency; A frequency analysis step of analyzing which part is a frequency corresponding to a frequency having a magnitude corresponding to a reference breakage frequency among the read frequencies; A second frequency comparing step of repeating the frequency analyzing step if there is another frequency whose magnitude coincides with the reference breaking frequency among the read frequencies; If there is no other frequency that matches the magnitude of the reference damage frequency among the read frequencies, based on the data identified in the frequency analysis step, the type of damaged parts, the path of the broken parts and the cause of the broken parts are output. The present invention relates to a structure and a diagnostic method of a premature failure diagnosis system of a vehicle transmission component.
