Analysis and Investigation of Tractor and Trailer Electrical System Capabilities

摘要

The ability of the tractor-trailer electrical systems to safisfy the electricalpowering and signalling demands of present and future electrical/electronic systems appears questionable. The study focused on this issue by: Characterizing the ability of a representative sampling of typical new and in-service truck tractors, and one tractor/double trailer combination, to provide electrical power through the stoplamp circuit; Postulating the type and number of electrical/electronic devices that might be installed on trailers in the future; Performing an analysis of the electrial wiring needed to reliably power, through the stoplamp circuit. ABS on multiple trailer combinations; and Suggesting improvements to enable the electrical systems of tracor/trailers to meet present and future electrical power and signalling demands.
