To improve the accuracy of a vehicle failure diagnosis.SOLUTION: A failure diagnosis system 1 includes a data acquisition unit 40 for acquiring driving environment data including driving operation data indicating at least driving operations and actual driving result data indicating actual driving results based on the driving environment data in a target vehicle subject to failure diagnosis, a proper range setting unit 42 that derives a proper range of actual driving results based on the driving environment data in a vehicle of the same model as the target vehicle, and a failure determination unit that determines whether the target vehicle has a failure by determining whether the actual driving result data falls within the proper range.SELECTED DRAWING: Figure 1
【課題】車両の故障診断の精度を向上させる。【解決手段】故障診断システム1は、故障診断の対象となる対象車両における、少なくとも運転操作を示す運転操作データを含む走行環境データと、走行環境データに基づく実際の走行結果を示す実走行結果データとを関連付けて取得するデータ取得部40と、対象車両と車種が等しい車両における、走行環境データに基づく実際の走行結果の適正範囲を導出する適正範囲設定部42と、実走行結果データが、適正範囲に含まれるか否かを判断することで対象車両の故障の有無を判断する故障判断部と、を備える。【選択図】図1
