Open/close control device, open/close control system, open/close control method, and program
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.
