To highly accurately evaluate the tire wear state of a vehicle with a simple configuration and at low cost.SOLUTION: A method for evaluating a tire wear state includes: a target route setting step S1 of setting a target route TR as a target when a vehicle C automatically travels; a travel track acquisition step S2 of acquiring a travel track P when the vehicle C automatically travels, from the positional data of the vehicle C obtained by a satellite positioning system; and a wear state evaluation step S3 of evaluating the wear state of a tire 20a on the basis of the amount of deviation D of a curve travel track Pc in a curve region Rc of the travel track P from a curve target route TRc in the curve region Rc of the target route TR.SELECTED DRAWING: Figure 7

    【課題】簡素な構成でかつ低コストに、車両のタイヤの摩耗状態を高精度に評価する。【解決手段】タイヤの摩耗状態評価方法は、車両Cが自動走行する際の目標となる目標経路TRを設定する目標経路設定工程S1と、衛星測位システムで得られた車両Cの位置データから車両Cが自動走行する際の走行軌跡Pを取得する走行軌跡取得工程S2と、走行軌跡Pのうちカーブ領域Rcにおけるカーブ走行軌跡Pcと、目標経路TRのうちカーブ領域Rcにおけるカーブ目標経路TRcとのずれ量Dに基づいて、タイヤ20aの摩耗状態を評価する摩耗状態評価工程S3とを備える。【選択図】図7
