Abstract: An open/close control device which detects pinching by an open/close body due to driving of a motor, includes a computing unit configured to compute an acceleration term based on a change in a rotational period of the motor, and a load applied to the motor based on the acceleration term, based on a signal indicating the rotation period of the motor, a determination unit configured to determine that the pinching by the open/close body occurred, when the load computed by the computing unit exceeds a predetermined determination value, and a determination value adjusting unit configured to increase the determination value when a local maximum value of the acceleration term exceeds a predetermined threshold value, or the acceleration term becomes less than or equal to a predetermined reference value, or the acceleration term decrease by a predetermined value or more, during a certain period after starting the motor.

Abstract: 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.
