To provide a wear amount estimation system, an arithmetic model creation system, and a wear amount estimation method that can improve accuracy of estimating an amount of wear of a tire.SOLUTION: A wear amount estimation system 100 comprises: a vehicle information acquisition unit 12; a tire severity degree calculation unit 13; and a wear amount calculation unit 14. The vehicle information acquisition unit 12 acquires information including a temperature of a tire 7 installed on a vehicle and a travel distance and an altitude of the vehicle. The tire severity degree calculation unit 13 calculates a degree of severity for wear of the tire on the basis of the temperature of the tire 7 and the altitude of the vehicle acquired by the vehicle information acquisition unit 12. The wear amount calculation unit 14 has an arithmetic model 14a that calculates an amount of wear of the tire on the basis of input information, and inputs the travel distance acquired by the vehicle information acquisition unit 12 and the degree of severity calculated by the tire severity degree calculation unit 13 to the arithmetic model 14a to calculate the amount of wear of the tire.SELECTED DRAWING: Figure 1
【課題】タイヤの摩耗量の推定精度を向上することができる摩耗量推定システム、演算モデル生成システムおよび摩耗量推定方法を提供する。【解決手段】摩耗量推定システム100は、車両情報取得部12、タイヤ過酷度算出部13および摩耗量算出部14を備える。車両情報取得部12は、車両に装着されたタイヤ7の温度、並びに車両の走行距離および高度を含む情報を取得する。タイヤ過酷度算出部13は、車両情報取得部12により取得したタイヤ7の温度および車両の高度に基づいてタイヤ摩耗に対する過酷度を算出する。摩耗量算出部14は、入力された情報に基づいてタイヤの摩耗量を算出する演算モデル14aを有し、車両情報取得部12により取得した走行距離、およびタイヤ過酷度算出部13により算出した過酷度を演算モデル14aに入力してタイヤの摩耗量を算出する。【選択図】図1
