ABSTRACT:
In one embodiment of the present invention, a "one-touch-up" power window system is provided for a motor vehicle. The system includes a controller which controls the power window motor. One function of the controller is to determine whether an obstruction impedes travel of the power window. The controller takes a plurality of samples of the electrical current drawn by the power window motor. If the last sample varies by more than a predetermined amount from any of the past samples taken over a predetermined distance of travel of the window, the controller concludes that an obstruction impedes the travel of the window. The controller then stops or reverses the power window motor to stop or reverse travel of the power window. In this embodiment of the present invention, distance of travel of the window can be inferred from rotations of the power window motor.
