Abstract
A method and system for detecting the presence of an object caught between an automotive window and its respective frame is provided. The window opens and closes via a regulator driven by an electric drive motor. A force is sensed at an interface between the window and the regulator proportional to a force exerted on the window. This force is compared with a predetermined value, and if the sensed force exceeds the predetermined value, an object caught between the window and its respective door frame is detected.
