TRACTOR-TRAILER COMMUNICATION SYSTEM

A communication system includes a trailer module disposed on a cargo trailer, the trailer module including a power line transceiver. The trailer module is programmed to use the power line transceiver to receive a data message from a second trailer module of a second cargo trailer that is following the cargo trailer and is connected thereto by a power line carrier. The trailer module is further programmed to forward data of the data message using the power line transceiver and power line carrier, the data being forwarded to a trailer module of a leading trailer or to a tractor module mounted in a tractor.
