Abstract:
1. A window position detection and anti-pinch system for a motor vehicle door assembly having a window adjustably positionable in a window frame by a reversible motor operatively connected to the window, the system comprising: a coding arrangement having a plurality of indicia uniformly spaced and correlated to convey the vertical position of the window in the window frame etched into a surface of the window; at least one sensing device disposed adjacent the window for detecting the position of the window relative to the window frame, the at least one sensing device detecting the coding arrangement provided on the window and generating an output signal representative of the detected position of the window; and a controller responsive to the output of the at least one sensing device for comparing the output signal against predetermined values to determine whether an obstruction exists between the window and window frame.
