  • Patent number: 5719713
    Abstract: An automatic side view mirror tracking and control system enables drivers of articulated vehicles such as tractor trailers to keep visual contact with the side and rear of the trailer throughout a turn while backing the vehicle. This is accomplished without driver intervention through the use of a microprocessor receiving the outputs of either a plurality of ultrasonic transducers or a pair of fluxgate compasses. The microprocessor uses the aforementioned outputs to determine the rotational angle between the trailer and the tractor. Based upon these determinations, the mirror is moved to a position commensurate with the subject angle so that the driver of the vehicle is able to view the side and rear corner of the vehicle. A software filter prevents the mirror from being moved unless a predetermined change in the vehicle angle is detected.
