To provide a road surface abnormality detection device that allows for easy application to a variety of vehicles and compares road surface abnormalities obtained for different vehicles in the same way.SOLUTION: A road surface abnormality detection device according to an embodiment includes: a wheel speed detection device that detects wheel speed values of a vehicle; a trend value generation unit that generates a trend value representing a trend of changes in wheel speed during traveling on a road surface based on a detected wheel speed value; and a determination unit that determines that an abnormality has occurred on the road surface when the difference between the wheel speed value and the trend value exceeds a predetermined threshold.SELECTED DRAWING: Figure 1

    【課題】様々な車両に容易に適用でき、車両が異なっても得られる路面異常を同列で比較する。【解決手段】実施形態の路面異常検知装置は、車両の車輪速値を検出する車輪速検出装置と、検出された前記車輪速値に基づいて路面の走行時における車輪速の変化傾向を表すトレンド値を生成するトレンド値生成部と、車輪速値とトレンド値の差が所定の閾値を超えた場合に路面に異常が発生していると判断する判断部と、を備える。【選択図】図1
