An analysis of automotive signal multiplexing-the J1850 requirement

Automotive electrical systems have historically not troubled the high-technology community of integrated-circuit designers and computer software engineers. In recent years though the increasing demand by consumers for ever more luxury on-the-move has necessitated a very wide range of electronically controlled add-ons to be fully integrated with the core design of the car. This in turn has put pressure on the wiring and control system, to be as efficient and compact as possible. The author examines the design and analysis of one such system able to achieve these goals
