Claim:
1. An abnormality determination system comprising: an autonomous moving object including a distance measuring unit that is disposed to face a road surface in a moving direction and that measures a distance to the road surface; a charging unit including a connection terminal for charging a battery of the autonomous moving object; a stepped portion disposed on a road surface which is subjected to measurement by the distance measuring unit when the autonomous moving object is connected to the connection terminal of the charging unit and is positioned at a predetermined position, the stepped portion being a reflecting portion configured to reflect a signal output from the distance measuring unit; and a determination unit configured to (i) determine whether a distance to the stepped portion measured by the distance measuring unit at a time of positioning of the autonomous moving object at the predetermined position is less than a threshold value, and (2) determine that the distance measuring unit is abnormal when the distance to the stepped portion, including the reflected light path of the reflecting portion, measured by the distance measuring unit at the time of positioning of the autonomous moving object is greater than the threshold value.
