Abstract: A window-anti-pinch system suitable to operate a powered-window in a vehicle includes a motor and a controller. The motor is coupled to a window by an apparatus. The motor is operable to raise the window when the motor is operated in a first-direction and lower the window when the motor is operated in a second-direction opposite the first-direction. The apparatus is characterized by slack between the motor and the window. The controller is in communication with the motor. The controller is configured to apply a slack-removal-signal to the motor prior to operation of the motor to raise the window when a most-recent-operation of the motor was effective to lower the window. The slack-removal-signal is a predetermined-waveform effective to operate the motor in the first-direction to take-up the slack but not raise the window.
