## Abstract

A mobile body moving device includes a mobile body moved to open and close an opening; a drive unit for moving the mobile body; a sensor for detecting movement of the mobile body; and a control unit controlling driving of the mobile body by the drive unit. In a high-speed region, the control unit controls the driving of the drive unit so that an actual speed of the mobile body calculated based on a detected value detected by the sensor is adjusted to a speed calculated by a target movement speed rule by comparing the actual speed and the speed calculated by the target movement speed rule, and in a low-speed region, the control unit controls the driving of the drive unit by comparing a predicted actual speed calculated by a predetermined low-speed movement speed rule and a predicted target speed calculated by the target movement speed rule.

## Claims

### Claim 1

A device comprising:
a mobile body that is moved to open and close an opening;
a drive unit that moves the mobile body in first and second directions to open and close the opening, respectively;
a sensor that detects the movement of the mobile body; and
a control unit that controls driving of the drive unit based on a target movement speed rule that prescribes a movement speed of the mobile body according to a position of the mobile body,
wherein
in a high-speed region where the mobile body moves at a speed faster than a predetermined speed, the control unit compares an actual speed of the mobile body detected by the sensor and the movement speed of the mobile body calculated by the target movement speed rule and controls the drive unit to adjust the actual speed of the mobile body to the movement speed of the mobile body calculated by the target movement speed rule,
in a low-speed region where the mobile body moves at a speed less than or equal to the predetermined speed, the control unit compares a predicted actual speed of the mobile body calculated by a predetermined low-speed movement speed rule and a predicted target speed of the mobile body calculated by the target movement speed rule and controls the drive unit to maintain a constant difference between the predicted actual speed of the mobile body and the predicted target speed of the mobile body, and
the predicted actual speed of the mobile body calculated by the predetermined low-speed movement speed rule is calculated by a predetermined program.
