Abstract
The processing device of the information processing device includes: a first step of calculating a relative frequency distribution of the original data; a second step of setting a plurality of time windows for clipping data of a part of the period of the original data; a third step of clipping data from the original data; a fourth step of calculating a relative frequency distribution in the extracted data; and a fifth step of calculating an error between the relative frequency distribution in the original data and the relative frequency distribution in the extracted data; and a search process of repeatedly performing the trial from the second step to the fifth step by changing the setting of the plurality of time windows, and calculating an index value of damage to the engine-disconnecting clutch using the extracted data whose error is equal to or less than the threshold value.
