Abstract: An opening and closing body control device includes a distance detection unit that detects a detection distance, which is a distance to a detected object around an opening and closing body, and a control unit. When a start command is input, the control unit determines whether the detected object is a moving object or a stationary object, sets a first or second collision determination distance as a collision determination distance depending on whether the detected object is moving or stationary. When the detection distance is smaller than the collision determination distance, the control unit controls the drive unit to stop operation of the opening and closing body.

Abstract: A door opening and closing device includes: first and second detectors repeatedly detect a distance to a detection target around the door; and a control unit opens and closes the door using a drive unit when a predetermined operation having a plurality of stages performed by a moving object is detected. The control unit determines whether first and second objects respectively detected by the first and second detectors are the moving or stationary object. When one of the first and second objects is the moving object and the other is the stationary object and a distance to the stationary object is shorter than a first determination value, both the detection results of the first and second detectors are used for detection at a final stage, and only the detection result of the first or second detector detecting the moving object is used for detection at the other stages.
