To provide a road surface state detection device and a road surface state detection method capable of detecting the state of a road surface accurately.SOLUTION: The road surface state detection device according to an embodiment comprises a detection unit and an estimation unit. The detection unit detects a vibrating state generated at an electric wheelchair by using a vibration sensor provided at a structure part which projects from the body frame of the electric wheelchair and is not in contact with a road surface. The estimation unit estimates the state of the road surface on the basis of the vibration state detected by the detection unit.SELECTED DRAWING: Figure 2

    【課題】路面の状態を高精度に検出することができる路面状態検出装置および路面状態検出方法を提供すること。【解決手段】実施形態に係る路面状態検出装置は、検出部と、推定部とを備える。検出部は、電動車椅子の車体フレームから突出した構造部であって、路面に接地しない構造部に設けられた振動センサによって、電動車椅子に生じる振動状態を検出する。推定部は、検出部によって検出された振動状態に基づいて、路面の状態を推定する。【選択図】図2
