Abstract
As centralization of automotive E/E (Electrical and/or Electronic) architectures becomes reality for future vehicles, it is crucial that existing assets be reused in the most efficient and effective manner. We report on our experience developing a new centralized E/E architecture for a propulsion domain, and migrating the corresponding propulsion elements of an existing decentralized, CAN-based architecture to a prototype of the centralized propulsion domain. Our migration adopts automotive Ethernet and supporting standards as a next-generation communications backbone technology; a next-generation computation platform from automotive supplier NXP; and a new automotive virtualization solution from OpenSynergy. We discuss aspects of legacy software reuse and adaptation; modification of vehicle HiL simulation models used in testing; existing vendor tool support; and implications arising from functional safety and the ISO 26262 standard.
