Title:

WEAR-CONDITION-SENSING DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/153277

Kind Code:

A1

Abstract:

Provided is a wear-condition-sensing device with which it is possible to accurately sense the progress of wear in the tread of a pneumatic tire. A wear-condition-sensing device 10 comprises an element 11 that generates voltage on the basis of deformation of the tread while the tire is rotating, a voltage detection unit 12 that detects the voltage generated by the element 11, a storage region 13 that stores chronological waveform data on the voltage detected by the voltage detection unit 12, a calculation unit 14 that calculates an index value of voltage change from the waveform data stored in the storage region 13, and a determination unit 15 that compares the index value calculated by the calculation unit 14 with reference information to determine the progress of wear in the tread.
