Abstract
An opening and closing body control apparatus includes a motor driving unit and a control unit. The motor driving unit outputs a predetermined application voltage to the motor, based on a control command from the control unit. The control unit is configured to: when an opening and closing body reaches a first position in front of a closing-up position, set a target speed of the motor to a closing-up time target speed at which a torque required for closing-up the opening and closing body is secured, and perform feedback control on the motor driving unit; and when the opening and closing body reaches a second position closer to the closing-up position than the first position, stop the feedback control, and control the motor driving unit so that the application voltage of the motor at the time is held.
