Abstract
An automatic mirror rotation assembly for a vehicle including a tractor and semi-detached trailer is provided. An elongated arm supporting a rotatable wheel attaches to a support mounted at a selected position on the tractor chassis. The arm is pivoted upward until the wheel contacts the underside of the trailer, and is kept engaged with substantially constant pressure. As the vehicle turns, the rotation of the trailer with respect to the tractor is measured by counting rotations or partial rotations of the wheel against the underside surface of the trailer. A corresponding degree of passenger-side rear view mirror is calculated, and a motor automatically rotates the mirror. A feedback device measures the actual rotation of the mirror and feeds that information back to the assembly.
