Abstract
A method for closing a motor-driven window is disclosed, including the steps of raising the window after the window has been stopped; evaluating the torque after initially raising the window; and stopping the window if the pinch force exceeds a predetermined limit. Torque is preferably estimated according to the present invention using the sum of dynamic torque, electromagnetic torque, and core loss compensation. Consistent values of torque are estimated during window starts and stops, which is beneficial in providing accurate pinch force measurements and avoiding false pinch indications.
