The trucking industry, through the formation of the Technology Demonstrator Consortium, has worked collaboratively with the Government to address the dynamics, both applications and limitations, of developing comprehensive powering and communication systems in heavy-duty vehicles. Two technology vehicles were used to demonstrate, deploy, and evaluate powering and communication interconnect technologies, as well as supporting technologies, i.e., safety, warning, and lighting systems. The test vehicles used the standard industry electrical connectors, which also served as communication channels to transmit SAE J1708, J1939, and power line carrier signals. The transfer of data between tractor and trailer, and the utilization of this information by various electrical subsystems, occurs as a result of effective powering and communication systems. The human factors element, although subjective, reflecting personal bias, perceptions, and experience, is also critical in examining the effectiveness of technology. The technology vehicles were placed into active fleet service, where their performance was evaluated according to maintenance/repair records, and mechanic/driver feedback. The industry/government needs to continue developing and evaluating current powering/communication systems to meet the demands and challenges of technological advancements. The future success of the trucking industry will depend on its ability to embrace changes, particularly those that impact its productivity, safety, and competitiveness.
