Abstract
The presence of an object in the path of an automotive vehicle window is detected. This is accomplished by sensing or observing a system variable, such as speed or motor current, and comparing this measured value to a predicted limit value of the system variable which is based upon the behavior of the system variable when there is no object present. The values are compared over predetermined time intervals and if the measured value falls out of the predicted limit value of the system variable in a direction that indicates an obstruction, then a control system detects the presence of an object and reacts accordingly by stopping or reversing the drive motor of the vehicle window.
