The Impact of Vehicle Boundary Conditions on the Effectivity of Multiplex for Load Control 850451

This paper presents an examination of the impact of vehicle boundary conditions on future multiplexed vehicle signal & energy distribution systems. Boundary conditions ore discussed including requirements for: l)circuit protection 2) function isolation 3) option flexibility 4) distributed input and load hardware 5) reliability 6) redundancy 7) cost effectiveness 8) diagnosability 9) assembleability and, 10) B+ and ground distributionBased on these boundary conditions, an evaluation is made of both electrical and optical multiplex systems. Different configurations are examined such as: 1) centralized load control, 2) distributed load control, 3) single ring, and 4) multiple ring. Parameters which relate to wiring system cost, complexity, and reliability are considered.
