To provide a personal mobility, obstacle detection system and wheelchair, capable of detecting an obstacle really interrupting a progress.SOLUTION: The present invention executes the following actions: detecting a level difference forward an electric wheelchair; storing, as a passage history, a height of a level difference through which a wheelchair has passed and a vibration or a tilt of the electric wheelchair having passed through the level difference; and when a passage history including a detected height has been registered after detection of a level difference forward a wheelchair, checking whether or not a vibration or a tilt shown in the passage history is within an allowable level, and if out of the allowable level, detecting it as an obstacle and outputting an alarm.SELECTED DRAWING: Figure 3

    【課題】真に進行を妨げることとなる障害物を検出できる「パーソナルモビリティ、障害物検出システム及び車椅子」を提供する。【解決手段】電動式車椅子の前方の段差を検知する。そして、検知した段差を通過した場合には、通過した段差の高さと、段差を通過したときの電動式車椅子の振動や傾斜を通過履歴として記憶する。また、電動式車椅子の前方の段差を検知したときに、検知した段差の高さを含む通行履歴が登録されている場合には、当該通行履歴が示す振動や傾斜が許容レベル内であるかどうかを調べ、許容レベル内でなければ障害物として検出し警報を出力する。【選択図】図3
