Abstract
X-by-Wire systems are expected to enhance vehicle driving performance and safety. This paper describes an electronic platform architecture for X-by-Wire systems that satisfies both cost-effectiveness and dependability. In the first part of this paper (Part 1), we have proposed a new electronic architecture based on a concept of autonomous decentralized systems. In the latter part (Part 2), the proposed architecture implementation to the actual vehicle control systems will be discussed. We clarify that, due to system level redundancy the proposed architecture provides, vehicle control systems can basically consist of low cost fail-silent nodes. Furthermore, for cost optimization, considering a tradeoff between hardware cost and fault detection coverage, we design a suitable hardware architecture for each node according to node function.
