To provide a road surface condition determination method and a road surface condition determination device capable of detecting a road surface bump with high accuracy.SOLUTION: A road surface condition determination method, which is performed by a road surface condition determination device that determines a bump on a road surface, includes: an acquisition step (S1) of acquiring travel data indicating travel states of a vehicle including positions, speeds, and accelerations in a height direction of the vehicle in a time series, and road map information; a detection step (S2) of detecting at least one abnormal value of acceleration based on a relationship between accelerations and speeds; an identification step (S3) of identifying a location of the bump on the road surface by mapping the location of the vehicle corresponding to the abnormal value to the road map information when the abnormal value is detected; and a creation step (S4) of creating step information, which is information about the identified bump on the road surface, including at least the location.SELECTED DRAWING: Figure 3

    【課題】路面の段差を高精度に検出可能な路面状態判定方法及び路面状態判定装置が提供される。【解決手段】路面状態判定方法は、路面の段差を判定する路面状態判定装置が実行する路面状態判定方法であって、車両の位置、速度及び高さ方向の加速度を含む車両の走行状態を時系列で示す走行実績データと、道路地図情報と、を取得する取得ステップ(S1)と、加速度と速度との関係に基づいて、加速度の異常値を検出する検出ステップ(S2)と、異常値が検出された場合に、異常値に対応する車両の位置と道路地図情報とを対応付けて、路面の段差の位置を特定する特定ステップ(S3)と、少なくとも位置を含む、特定された路面の段差についての情報である段差情報を作成する作成ステップ(S4)と、を含む。【選択図】図3
