To prevent the decline in road surface condition estimation accuracy even when the motion of the vehicle's sprung weight portion is regulated by a motion control device.SOLUTION: A road surface condition estimation device includes: a data acquisition unit for acquiring driving state data representing the driving state of a vehicle and operation data representing physical parameters associated with the operation of a motion control device, which is installed in the vehicle and either manages or affects the movement of the vehicle's sprung weight portion with respect to the road surface; and a road surface condition estimation unit for estimating the condition of the road surface based on the driving state data and the operation data.SELECTED DRAWING: Figure 4

    【課題】運動制御装置によって車両のばね上部の運動の制御を行った場合でも路面状態の推定の精度が低下するのを抑制する。【解決手段】路面状態推定装置は、車両の走行状態を示す走行状態データと、車両に搭載され路面に対する車両のばね上部の運動を制御する又はばね上部の運動に影響を及ぼす運動制御装置、の動作に関する物理量を示す動作データと、を取得するデータ取得部と、走行状態データと動作データとに基づいて、路面の状態である路面状態を推定する路面状態推定部と、を備える。【選択図】図4
