Modularisation of Safety & Control for X-By-Wire Multiapplication-Platforms 2008-01-0113
This paper shows a realisation approach for functional safety considerations for X-by-Wire vehicles. The E/E architecture has been built up as a redundant highly-safety-critical multiapplication platform with access to all sensors and actuators (so called satellites) ensuring different safety integrity levels besides reliability. Such it will be possible to develop high-level control functions (HCFs) independently of the overall vehicle E/E architecture, redundancy and even data-flow. This means that herein an approach is shown of how to split the responsibility of safety and the development of intelligent vehicle control-functionality. The feasibility has been shown within the EC-funded project SPARC (www.sparc-eu.net). The paper focuses on the identification of functions being implemented in software to ensure safety. The detailed design of the mechanisms themselves will not be part of this paper.
