To easily specify a fault being a factor of a prescribed phenomenon, when the prescribed phenomenon occurs in a vehicle.SOLUTION: When an abnormal phenomenon occurs in a vehicle 10, an arithmetic unit 102 specifies a fault being a factor of the abnormal phenomenon in the vehicle 10, on the basis of: multiple pieces of data expressing a travel state before occurrence of the abnormal phenomenon in the vehicle 10; and learning results that associate multiple pieces of data expressing a travel state before occurrence of an abnormal phenomenon in another vehicle 200, with a fault being a factor of the abnormal phenomenon in the other vehicle 200, according to the arithmetic unit 102 of a server 100. Accordingly, it is possible to specify a fault that is difficult to specify with the vehicle 10 alone. Thus, when an abnormal phenomenon occurs in the vehicle 10, a fault being a factor of the abnormal phenomenon can be easily specified.SELECTED DRAWING: Figure 8
【課題】車両にて所定の現象が発生した際に、その所定の現象の要因となる故障を容易に特定する。【解決手段】車両10における異常な現象の発生時に、車両10における異常な現象の発生前の走行状態を表す複数のデータと、サーバー100の演算部102による他車両200における異常な現象の発生前の走行状態を表す複数のデータと他車両200における異常な現象の要因となる故障とを関連付ける学習結果とに基づいて、車両10における異常な現象の要因となる故障が演算部102を用いて特定されるので、車両10単独では特定することが難しいような故障を特定することが可能となる。よって、車両10にて異常な現象が発生した際に、その異常な現象の要因となる故障を容易に特定することができる。【選択図】図8
