Abstract

Methods for connected tractor and trailer identifications and the order of hook-up of multiple trailers to a tractor enable the tractor and trailer identification and the order of trailer hook-up to be remotely broadcast from the tractor or trailers. In one aspect, the detection of vehicle identification and the order of trailer hook-up are determined by PLC tags mounted in the trailers or by a PLC Gateway mounted in the tractor or one of the trailers utilizing the PLC system on the tractor/trailers. In another aspect, the vehicle identifications are extracted from electronic modules existing on the tractor and trailers and sent to the PLC Gateway for broadcast from tractor/trailer.op
