Résumé / Abstract

The number of el.loads, sensors and control units in a vehicle increases due to the introduction of new functions, the electrical realization of formerly mechanical devices and because of higher security and technical standards. This trend has lead to very complex electrical distribution systems (EDS). The EDS development becomes a considerable challenge under current and future weight, cost, and packaging constraints. Thus the current and future demand for compact, fuel efficient vehicles loaded with electrical functions requires further optimization and innovation. By definition, the EDS must provide the distribution of signals and power. The power distribution is, by weight, the larger part of the EDS and is strongly dependent on its geometrical topology, which is defined by the routing of the wiring harness (w/h) and by the position of the electrical components and boxes. Based on the assumption of an existing data network and local power distribution boxes with fusing and switching capabilities, the parameters that may be varied for optimization purposes are the number and functional contents of the above mentioned boxes and the optional routings of the w/h. In order to realize a systematic approach, an algorithm has been developed. For each specified topology, it generates a 3D plot showing the required copper weight (of the power distribution part of the EDS) as a function of the position of the central power distribution box in the vehicle, In this paper, examples based on a real vehicle as well as a comparison of alternative topologies are given.
