Abstract
An opening and closing control device includes a motor configured to drive, in an opening and closing direction, an opening and closing body that is supported a vehicle body and allowed to be opened and closed, a controller configured to control the motor, and a pulse encoder configured to output a pulse signal. The controller adjusts an advance angle of the motor, detects a rotational speed of the motor or an opening and closing speed of the opening and closing body according to pulse detection based on the pulse signal output from the pulse encoder, and detects a pinching state of the opening and closing body when the rotational speed of the motor or the opening and closing speed of the opening and closing body is equal to or less than a threshold value during advance angle control on the motor.
