To provide a road surface assessment device capable of assessing the road surface condition using a simple configuration even in the absence of tire slippage.SOLUTION: A road surface assessment device is provided, comprising: an acceleration detection unit 10 configured to detect acceleration of a vibration transfer member that transfers vibration from a vehicle body or tire to the vehicle body; and a road surface assessment unit 20 configured to assess the road surface condition using an assessment value obtained by extracting a predetermined frequency band component from the acceleration detected by the acceleration detection unit and integrating the extracted component.SELECTED DRAWING: Figure 1
【課題】簡単な構成によりタイヤの滑りが生じていない状況でも路面状態を判定可能な路面判定装置を提供する。【解決手段】路面判定装置を、車体又はタイヤから車体に振動を伝達する振動伝達部材の加速度を検出する加速度検出部10と、加速度検出部が検出する加速度から所定の周波数帯域の成分を抽出して積算して得た判定値を用いて路面の状態を判定する路面判定部20とを備える構成とする。【選択図】図1
