Title:
TIRE DEGRADATION ESTIMATING DEVICE, AND TIRE DEGRADATION ESTIMATING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/250517
Kind Code:
A1
Abstract:
A tire degradation estimating method according to an embodiment of the present invention enables a degree of degradation of a tire to be estimated, by comprising: a deformation speed measuring step (S11) of using a tire degradation estimating device disposed on an inner side surface of the tire to measure a tire deformation speed, which is the deformation speed of the tire when the tire is rotating, and obtaining a time-series variation of the tire deformation speed; a calculating step (S12) of calculating a peak value of the tire deformation speed from the time-series variation of the tire deformation speed; and an estimating step (S13) of estimating the degree of degradation of the tire using a first peak value, which is the peak value of the tire deformation speed before lead-in of the tire or after trail-out of the tire, in the time-series variation of the tire deformation speed.
