CALIBRATION METHOD OF LOAD HISTORY MEASURING SIGNAL FOR LIFE PREDICTION

摘要

In order to reduce the processing time of the computer and increase the accuracy of the prediction by eliminating unnecessary signals in the processing method that processes the signal corresponding to the load history of the vehicle to predict the life of the vehicle, If the historical data is continuously input with the same value by reading the inputted data, removing only one data and removing the remaining data; and removing the data that does not affect the operation operation among the read data. Removing the intermediate value read while the gradient sign of the data is changed, setting a range of maximum and minimum values to remove weak load history that does not affect the life of the part, and maximum of the input data. The value is at the beginning and end of the operation cycle Rearranging the order of the input data so as to be located in the film; and the same slope as the value within the set range to once again remove the data corresponding to the set range set through the operation and the intermediate value that may occur in the calibration step. And removing the median value, which may occur in the direction of, and using the data corrected by removing the median value as data for life expectancy.
