ABSTRACT:
An anti-pinch control system is used to identify obstructions in a path of movement for a powered vehicle member, such as a vehicle window for example. A pinching area is identified for the vehicle window and at least one indicium or indicator is mounted to a vehicle structure to be in view of a camera. The indicium is positioned such that no object may pass into the pinching area without also passing between the camera and at least a portion of the indicium. The camera identifies an obstruction when any portion of the indicium is obscured. This indicium includes a plurality of predefined zones, with each zone being associated with an operational function, such as upward window movement, downward window movement, door locking, side mirror movement, etc. This eliminates the need for separate switches to perform each of these functions thereby reducing overall cost for a vehicle door system.
