Abstract
In an opening/closing body control device, catching determination part () determines whether or not a catching in an opening/closing body has occurred based on a value of current that flows in a motor; a plurality of sensors (to) disposed to be shifted by predetermined electrical angles detect positions of magnetic poles of the motor (); a counterclockwise pattern storage unit () stores a counterclockwise pattern which is a pattern corresponding to outputs of the plurality of sensors (to) and a predetermined shift in the electrical angles; and drive command part () controls the drive circuit () using a clockwise pattern or the counterclockwise pattern based on the outputs of the plurality of sensors (to), and in a case where the catching determination part () determines that a catching has occurred, controlling the drive circuit () in a predetermined pattern for eliminating the catching.
