In order to allow the realization of todays functionalities, automotive electric/electronic architectures (e/e-architecture) have changed from an aggregation of isolated systems to fully interconnected networks. In parallel, the number of ECUs in passenger cars rose to 70 or even 80. The future is going to see a melt of system boundaries, when even more functionalities which link several systems together, are to be integrated. Coping with complexity will be even more important. Still, costs remain the main driver in the development of e/e-architectures. At Robert Bosch GmbH, a method based on graph theory was developed for the design and the assessment of e/e-architectures. It enables systematic analyses and gives indications for the structural design of architectures under development. In this paper, the method will be presented. The partitioning and mapping of software components of a predictive evasion function is used as an example. The method has been applied to several projects. Different architectural approaches for the chassis domain were assessed. One major result is a deduction of a hierarchical structure with centralized and scalable domain control units that will be presented at theend of this paper.
