Abstract

See full text

With respect to an opening/closing control device for controlling an opening/closing operation of an opening/closing body driven by a motor, the opening/closing control device includes a current detector, a voltage detector, a processor, and a memory. The processor calculates the speed of the opening/closing body based on a change in the detected position of the opening/closing body, and decreases the pinch threshold value in a case where a state, in which the calculated speed of the opening/closing body is less than or equal to a first predetermined threshold value, and a temporal change in the calculated load is greater than or equal to a second predetermined threshold value and less than or equal to a third predetermined threshold value, continues for a certain period of time or greater.
