Motorized opening frame e.g. window regulator glass pane, closing force limiting method for motor vehicle, involves stopping motor, which drives opening frame, when closing force attains preset value i.e. constant value

摘要

The method involves calculating closing force at each instant of displacement of an opening frame during closing, based on a difference between force i.e. total force, applied to the frame when an edge of the frame is situated in a zone of a sealing line or crushes the line and force i.e. transfer force (Ft), applied to the frame just before the edge enters into the zone or crushes the line. An electric motor, which drives the frame, is stopped when the closing force attains a preset value (Ff) i.e. constant value.
