More Information
Summary:An opening/closing body control device is provided that can quickly detect pinching even when the opening/closing body is bent due to the pinching.An opening/closing body control device includes a motor drive unit that drives a motor for opening and closing the opening/closing body, and a control unit that controls an operation of the motor drive unit. The opening/closing control device includes a difference value calculator that calculates a current difference value that is a difference between a present value and a past value of a motor current, a differential value calculator that calculates a differential value of the current difference value, an adder that adds the current difference value and the differential value, and a pinching detection unit that judges whether or not pinching occurs at the opening/closing body based on a comparison result between the added value and a threshold.
