To appropriately confirm the condition of a road surface of a road even if a detection condition of a vehicle side is different.SOLUTION: An arithmetic unit includes a vehicle behavior information acquisition part for acquiring vehicle behavior information showing a vehicle behavior detected by a plurality of sensors provided at different positions of a vehicle 10 traveling on a road, and a road surface condition information acquisition part for acquiring road surface condition information showing a road surface condition of the road by estimating a transfer function showing a relation between the road surface condition of the road as an input and the vehicle behavior information as an output on the basis of a plurality of pieces of vehicle behavior information.SELECTED DRAWING: Figure 5
【課題】車両側の検出条件が異なる場合であっても、道路の路面の状態を適切に確認する。【解決手段】演算装置は、道路を走行する車両10の異なる位置に設けられる複数のセンサによって検出された、車両の挙動を示す車両挙動情報を取得する車両挙動情報取得部と、複数の車両挙動情報に基づいて、入力としての道路の路面状態と、出力としての車両挙動情報との関係を示す伝達関数を推定することで、道路の路面状態を示す路面状態情報を取得する路面状態情報取得部と、を含む。【選択図】図5
