A Software Safety Process for Safety-Critical Advanced Automotive Systems

摘要

A new generation of advanced automotive systems are being implemented to enhance vehiclesafety, performance, and comfort. As these new, often complex systems are added, system safetyprograms are employed to help eliminate potential hazards. A key component of these advancedautomotive systems is software. Software itself cannot fail or wear out, but its complexitycoupled with its interactions with the system and the environment can directly and indirectly leadto potential system hazards. As such, software safety cannot be considered apart from systemsafety, but the unique aspects of software warrant unique development and analysis methods.In this paper we describe the main elements of a software safety process for safety-criticaladvanced automotive systems. We describe how this proposed process may be integrated with anestablished system safety process for by-wire automotive systems, and how it may be integratedwith an established software development process.
