METHOD FOR ESTIMATING THE WEAR STATE OF A TIRE

A method for estimating the state of wear of a tyre, comprising the steps of:-recording a vibratory acoustic signal (1001) generated by the rolling of the tyre on a road during a time frame; -converting the time signal (1001) into a frequency signal (1002) in a frequency range; -segmenting the frequency range into frequency bands and associating, with each frequency band, data items representing the frequency signal, representing variables of the data items forming a matrix (1003); -predicting, under known driving conditions, the wear state from a matrix, according to a program each representing the wear state of the tyre, by machine learning (1004) based on data of a training library consisting of a set of matrices relating to the measurements according to the same step; and-determining the wear state of the tyre after N identical predictions of the series of M consecutive predictions (1005). 一种用于估计轮胎的磨损状态的方法，包括以下步骤：-记录在时间帧期间由轮胎在道路上滚动所产生的振动声学信号(1001)；-将时间信号(1001)转换为频率范围内的频率信号(1002)；-将频率范围分割成频带，并且将表示频率信号的数据项与
