摘要： A rear view mirror rotation system compensating for the relative movement of a tractor-trailer combination having a mechanical sensing device adjacent the ''''fifth wheel.'''' The relative mechanical rotation is converted to an analog electrical signal for rotating the appropriate rear view mirror so that the driver can maintain a line of vision to the rear wheels of the trailer. Hook-up and initial alignment of the system is quite simple requiring only the attachment of a sensor and certain adjustments to the electrical circuitry that can be made by the driver of a rig from within the cab of the tractor. No substantial modification or adaptation of the trailer is required other than to provide a simple retainer or fastener for the sensor. Thus, a tractor equipped with the system can be used universally with any trailer.
