ABSTRACT:
A power window control for a motor vehicle provides express or one-touch movement in response to short activations of a control element and traditional power window movement during activation of the control element for longer periods. The control provides for automatic window closing with activation of a power door lock element, as long as the ignition is off unless the ignition key is in the ignition switch and the driver's door is open. This allows single touch vehicle locking but helps prevents the operator from locking himself out of the vehicle with the key still inside. Window movement, once initiated in the open or close direction, is stopped in response to motor stall when the open or closed limit is reached. It is also stopped in the closing direction and reversed to the opening direction in response to a special impediment sensor comprising a flexible tube with an inner reflective surface adjacent the window closing path which directs light from an oscillator controlled light sending element to a light sensing circuit electronically synchronized with the sending element, when an impediment is pushed by the closing window into the tube to collapse it and block the light communication. Circuitry is disclosed for accomplishing the aforementioned features.
