Future vehicles are expected to evolve towards enabling fully electric and autonomous driving. However, technically this evolution requires fundamental changes of traditional automotive engineering principles. Specifically, challenges arise for the Electric/Electronic (E/E) vehicle architectures as underlying basis for almost all car functionalities. Higher demands on vehicle system’s flexibility and dependability have to be incorporated. We present a novel approach for such future E/E-architectures which considers these requirements as first principles by exploiting runtime adaptation capabilities. Based on use cases, a generic hardware and software architecture is presented which enables technology-independent realization of the provided concepts. Additionally, the incorporated generic failure management and design support are introduced. The approach has been evaluated in different prototype demonstrators, including an e-vehicle prototype compromising enhanced driving functionality. Thereby, the advantages of the concepts for future vehicle E/E-architectural development could be highlighted.
