EDS Ground Topologies for Composite-Bodied Motor Vehicles 2008-01-1268
The presence of composite-bodied vehicles in the non-specialist marketplace is challenging the original equipment manufacturers (OEMs) and their tier-one suppliers (T1s) in terms of how best to replace a metal body structure as a means of completing electrical circuits. Alternative wiring topologies are considered, their key electrical and mechanical characteristics are compared and an optimum solution is proposed. Its performance is quantified by calculation and modelling and then compared with actual measurements taken from a vehicle simulator. These are benchmarked against typical values which are found in welded-steel body structures.
