Most errors in critical systems arise in the requirements. Consistency and completeness of such requirements as well as their traceability throughout the development are very important. However, it has been found that the current revision of IEC 61508:2010 does not require either requirement to be checked. We propose that clauses be added to IEC 61508 in the forthcoming maintenance cycle to require...
Safety and security disciplines are often independent domains, with little interaction. There is increasing convergence driven by common technologies, platforms and networking, where safe operation of complex systems requires appropriate security. The two disciplines may also conflict, creating new hazardous that may require new safety functionality to reduce the security derived risk. Solely using...
The safety of vehicle electronic systems can be compromised by a malicious attack. In this paper, the authors describe their pragmatic approach to efficiently integrate the previously separate “security” aspects into the mature safety processes at an automotive Tier-1 supplier. Examples are given from the development of an electrical power steering controller.
In this paper, we present a software tool for automotive safety engineering called AVL Safety Extensions (AVL_SE). The tool is part of a software tool framework and supports a workflow for model-based system safety engineering of HEV (hybrid electric vehicle) powertrain E/E (electrical and/or electronic) systems. We focus on AVL_SE's features which allow synchronising safety requirements in the model...
