Time-Shared Multiplexing System Applied to Motor Vehicles 760181

Although motor vehicle electrical systems have been continuously increasing in complexity over the past 30 years or so, little attention has been paid to the wiring harness beyond changes to packaging and terminations.
Sporadic efforts have been made to demonstrate the practicability of systems which, by virtue of the use of a power supply ring, have borne the somewhat misleading name of Ring Main Signalling systems. All have attempted to simplify the unwieldy conventional harness by replacing it with a number of signalling leads packaged with the power ring.
This paper deals primarily with the application of a Time-shared Multiplexing System to public service vehicles and postulates the advantages of such a system over others which have been proposed.
