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.

First claim

1 . An opening-closing body drive device comprising:
a motor that opens and closes an opening-closing body; and a controller that controls driving of the motor, wherein the controller recognizes an arrested position of the motor during a dosing 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, and 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.

2 . The opening-closing body drive device according to claim 1 , wherein the set position is set toward the opening direction side of the reference position.

3 . The opening-closing body drive device according to claim 1 , wherein the set position is set at a position that is the same as the reference position.

4 . The opening-closing body drive device according to claim 1 , wherein
the controller performs a soft stop process that stops supplying power to the motor before rotation of the motor is arrested during the closing action, and when having performed the soft stop process an N number of times after updating the reference position, the controller does not perform the soft stop process in a next closing action.

5 . An opening-closing body drive device comprising:
a motor that opens and closes an opening-closing body; and a controller that controls driving of the motor, wherein when rotation of the motor is arrested during a closing action, the controller recognizes an arrested position as a reference position and performs an entrapment detection process in a section excluding a mask section having a predetermined length from the reference position toward an opening direction side, the controller stores an initial reference position that is the reference position in initial setting, and when rotation of the motor is arrested during a closing action, the controller corrects the length of the mask section to offset a difference of the arrested position and the initial reference position.

6 . The opening-dosing body drive device according to claim 5 , wherein
the controller performs a soft stop process that stops supplying power to the motor before rotation of the motor is arrested during a closing action, and when having performed the soft stop process an N number of times after updating the reference position, the controller does not perform the soft stop process in a next closing action.
