Zusammenfassung:An article transport vehicle traveling along a travelling path includes an obstacle sensor for detecting an obstacle existing in a detection area; and a control part for controlling the traveling speed of the article transport vehicle based on the detection information of the obstacle sensor. Considering an situation in which a non-detection area in which an obstacle is not detected by the obstacle sensor is set within the detection area of the obstacle sensor, and a non-detection area exists on a detection line connecting a part of the detection area and the obstacle sensor as a specific situation, the control part decelerates the article transport vehicle to a second traveling speed lower than a first traveling speed when there is an undetectable area in the detection area where the obstacle cannot be detected, because there is a shield in the non-detection area as a specific situation. Even in the situation where the non-detection area exists, it is possible to prevent the article transport vehicle from coming into contact with the obstacle by appropriately controlling the transport vehicle. 주행 경로에 따라 주행하는 물품 반송차는, 검지 영역에 존재하는 장애물을 검지하는 장애물 센서와, 장애물 센서의 검지 정보에 기초하여 물품 반송차의 주행 속도를 제어하는 제어부를 구비하고, 장애물 센서의 검지 가능 영역 내에, 장애물 센서에 의한 장애물의 검지를 행하지 않는 비검지 영역이 설정되고, 검지 영역의 일부와 장애물 센서를 연결하는 검출 라인 상에 비검지 영역이 존재하는 상황을 특정 상황으로 하여, 제어부는, 특정 상황으로서, 또한 비검지 영역에 차폐물이 존재하므로, 검지 영역 중에 장애물을 검지할 수 없는 검지 불가 영역이 존재하는 상황으로 된 경우에는, 물품 반송차를 제1 주행 속도보다 저속의 제2 주행 속도로 감속시킨다.
