Opening-closing body drive device

Abstract

An opening-closing body drive device includes a motor that opens and closes an opening-closing body; and a controller that controls driving of the motor. The controller recognizes an arrested position of the motor during a closing action as a reference position and performs an entrapment process in a section excluding a mask section from the reference position to a predetermined position toward an opening direction side. The controller updates the reference position when the arrested position of the motor is located toward a closing direction side of a set position, which is set in the mask section, and does not update the reference position when the arrested position of the motor is located toward an opening direction side of the set position.

Dependencies are inferred from the claim text.
