PROBLEM TO BE SOLVED: To provide a road surface information collection device capable of collecting road surface information with a simple method, and a road surface information analysis device.SOLUTION: A control part 2 of an on-vehicle device 1 acquires a plurality of wheel rotational speed from a speed sensor 25 mounted on a vehicle in advance for detecting the wheel rotational speed, determines that it is wheel velocity anomaly when variations of the rotational speed exceeds determination difference to transmit, to a server 50, the wheel rotational speed together with positional information of the vehicle.SELECTED DRAWING: Figure 1

    【課題】簡便な方法で路面情報を収集することができる路面情報収集装置および路面情報解析装置を提供する。【解決手段】車載機器1の制御部2は、車両に予め搭載されている車輪の回転速度を検出する速度センサ25から複数の車輪の回転速度を取得して、その回転速度のばらつきが判定差を超えた場合には車輪速度異常と判定し、車両の位置情報と共にサーバ50に送信する。【選択図】図1
