Summary
This report, produced by the Volpe National Transportation Systems Center for the National Highway Traffic Safety Administration (NHTSA), addresses the growing safety challenges associated with the increasing complexity and prevalence of electronic control systems in modern vehicles. As automotive design shifts toward software-intensive features and higher levels of automation, ensuring the reliability of these systems becomes critical. The study was motivated by the need to expand the knowledge base on automotive electronics reliability and to strengthen the implementation of voluntary industry standards. Specifically, it aims to assess existing safety standards to identify strengths, limitations, and opportunities for enhancement to support the development of robust functional safety approaches. The research methodology involved a comparative assessment of six relevant industry and government safety standards: ISO 26262 (Road Vehicles - Functional Safety), MIL-STD-882E (Department of Defense Standard Practice), DO-178C (Software Considerations in Airborne Systems), Federal Motor Vehicle Safety Standards (FMVSS), AUTOSAR (Automotive Open System Architecture), and MISRA C (Guidelines for the Use of the C Language in Critical Systems). These standards were analyzed across eleven specific dimensions, including the type of standard, definitions of safety and hazard, hazard analysis methods, risk assessment approaches, software safety considerations, system lifecycle coverage, human factors, and certification processes. ISO 26262 was identified as the most directly applicable standard, while the others were reviewed due to their frequent citation by industry practitioners and the ISO committee. The findings highlight significant variations in how these standards approach safety assurance. Process prescription standards like ISO 26262, MIL-STD-882E, and DO-178C prescribe systems engineering processes, whereas FMVSS relies on performance-based testing. The study observed that hazard definitions and risk assessment metrics vary considerably; for instance, ISO 26262 uses exposure and controllability, while DO-178C relies on severity for software risk. Key limitations identified include the lack of precise definitions for "unreasonable risk" in existing process standards, insufficient integration of human factors studies, and the absence of explicit guidance on environmental impacts throughout the vehicle lifecycle. Additionally, the report notes that while AUTOSAR and MISRA C support safety through architecture and coding guidelines, they do not comprehensively address system-level safety assurance on their own. The significance of this assessment lies in its provision of a structured framework for improving automotive functional safety standards. The report concludes that existing standards could be enhanced by adopting clearer risk definitions, integrating human factors more thoroughly, and leveraging the design-for-safety frameworks found in MIL-STD-882E. These observations are intended to inform future NHTSA policy and regulatory decisions, as well as guide the industry in developing more robust, comprehensive safety standards for the next generation of automated and connected vehicles.
Key finding
Process safety standards complement performance-based regulations like FMVSS but vary significantly in their definitions of safety and hazard, with opportunities for enhancement in risk assessment and human factors integration.
