Contemporary software architectures: Federated and centralized

Abstract

Automotive software architectures evolve together with the evolution of the electronics in vehicles. The distributed electronics of the cars of the 2000s and 2010s have started to reach the limit of their potential, and new electronic architectures are being introduced. In this chapter, we explore and discuss two of such new developments-federated architectures and centralized ones. These two architectural styles are a response to the challenges of distributed architectures with over 100 ECUs. Signaling, coordination, and integration drive the development of vehicles' electronics to use fewer, more powerful ECUs with redundancy and virtualization. In this chapter, we explore these techniques and show how they are, and can be, used in vehicles' software.
