Centralized architecture approach for functional and geometrical integration

In order to allow the realization of today's 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 electronic control units (ECUs) in passenger cars has increased to 70 or even 80. The future is going to see a melt of system boundaries, when even more functionalities, that link several systems, require to be integrated. Coping with complexity will be even more important. Still, costs remain the main drivers in the development of e/e-architectures. At Robert Bosch GmbH a method to design and assess e/e-architectures was developed. Different architectural approaches for the chassis domain were assessed and the major assessment results are described. Accordingly, a deduced centralized and scalable solution is presented.
