At the same time, the task load as well as the needs for performance increase. To address this problem, the A3Fa research project evaluates scalable distributed concepts for future vehicle system architectures. These can be seen as comparable to cluster-computing systems, which are applied in high-performance or high-availability use-cases. Methods used in such scenarios will also be important features in future vehicle architectures such as horizontal application scalability, application load balancing and reallocation, as well as functionality upgrades triggered by the user. This paper focuses on concepts and methods for the reliability of applications and hardware in future in-vehicle distributed system architectures. It is argued that future automotive computing systems will evolve towards enterprise IT systems similar to today’s data centers. Furthermore, it is stated these vehicle systems can benefit greatly from IT systems. In particular, the safety against failure of functions and hardware in such systems is discussed. For this purpose, various of such mechanisms used in information technology are investigated. A layer-based classification is proposed, representing the different fail-safe levels.

Many sensors and Electronic Control Units are added to the current vehicle architecture and further safety requirements like reliability become even more necessary. In this paper we present a potential evolution of the Electrical/Electronic-Architecture, including a Zone Architecture, to enable future functionality. We reveal the impact on the communication network concerning these architectures and present a potential communication technology to facilitate such architectures.
