MULTIPLEX SYSTEMS FOR AUTOMOBILES
Multiplexing is recommended as the best functional and most cost-effective approach for future automotive electrical wiring systems. The proven advantages of a multiplex control system are listed: reduced number of circuits, small gauge control wires, smaller installation space requirement, lower installation weight, expandability for added functions, and standardized harness configuration. Technology employed in multiplex data systems for automotive applications is discussed: Time Division Multiplex (TDM) systems, spoke and ring types of data links, and data word format and typical communication cycle for spoke type TDM systems. Electromagnetic compatibility considerations are addressed. Circuits are diagrammed for an "OPTIPLEX" test vehicle developed by General Motors, a 1979 Oldsmobile station wagon equipped with fiber optic steering column and door/seat multiplex harness systems.
