To provide a method and device for distinguishing the tire type of a tire running from a vehicle side.SOLUTION: When, from the output of an acceleration sensor attached to the tire tread inner surface side of a tire mounted on a vehicle, a tire type which is the type of the tire is distinguished, feature vectors are extracted from an acceleration waveform detected from the output of the acceleration sensor. From the extracted feature vectors, the tire type of the tire is distinguished by a machine learning algorithm. The tire type is distinguished on the basis of the extracted feature vectors and a distinguishing model which is constructed by using feature vectors obtained in advance for each tire type as learning data.SELECTED DRAWING: Figure 5
【課題】車両側から走行中のタイヤのタイヤ種を判別する方法とその装置を提供する。【解決手段】車両に取付けられたタイヤのタイヤトレッド内面側に装着された加速度センサーの出力から前記タイヤの種類であるタイヤ種を判別する際に、加速度センサーの出力から検出された加速度波形から特徴ベクトルを抽出し、この抽出された特徴ベクトルから、機械学習アルゴリズムにより、タイヤのタイヤ種を判別するようにした。タイヤ種の判別は、記抽出された抽出された特徴ベクトルと、予めタイヤ種毎に求めておいた特徴ベクトルを学習データとして構築した判別モデルとに基づいて行う。【選択図】図5
