PROBLEM TO BE SOLVED: To provide a vehicular abnormality diagnostic device capable of taking a balance between the properly shortening a transfer time period till a transfer from an abnormality occurrence to a fail-safe control, and a suppression of an erroneous fixation.SOLUTION: A vehicular abnormality diagnostic device comprises: an abnormality decision part for deciding the abnormality of a vehicle, in the case where the abnormality of the vehicle is continuously detected during an abnormality fixing time period; a control execution part for executing a fail-safe control in the case where the abnormality of the vehicle is decided by the abnormality decision part; and a time setting part for setting an abnormality decision time longer in which the driving difficulty is low, than that of the case in which the driving difficulty is high, in accordance of a parameter relating to the driving difficulty of a driver.SELECTED DRAWING: Figure 3
【課題】異常発生からフェールセーフ制御へ移行するまでの移行時間の短縮と、異常の誤確定の抑制とのバランスを適切に取ることが可能な車両の異常診断装置を提供する。【解決手段】異常確定時間の間、継続して車両の異常を検知した場合に、車両の異常を確定する異常確定部と、異常確定部により車両の異常が確定された場合に、フェールセーフ制御を実施する制御実施部と、ドライバの運転難度に関連するパラメータに応じて、運転難度が低い場合は高い場合よりも、異常確定時間を長く設定する時間設定部と、を備える。【選択図】図3
