Key standards

  • ISO 26262 (Road vehicles – functional safety), ISO/PAS 21448 (SOTIF), UNECE R155/R156 (cybersecurity/software updates).

Documented issues

A commentary in In Compliance Magazine notes that sudden unintended acceleration persists in vehicles with electronic throttle control. The authors argue regulators should mandate functional safety techniques based on peer-reviewed public standards like ISO 26262. They highlight that the automobile industry lacks independent safety assessors, unlike aviation, rail and medical devices. incompliancemag.com.

The article contends that automakers blame drivers for accidents when electronic malfunctions may be at fault and that regulators have failed to intervene. incompliancemag.com.

Typical challenges

  • Automakers rely on proprietary safety processes without external review.
  • ISO 26262 adoption varies widely; smaller suppliers may not understand ASIL classification or safety lifecycle.
  • Accidents due to electronic malfunction may be misattributed to driver error.
  • Difficulty in verifying software reliability across complex, integrated systems.

Best Practice playbook

  1. Implement ISO 26262 lifecycle processes across concept, design, integration and test; allocate ASILs to functions and apply appropriate methods (hazard analysis, FMEA, FMEDA).
  2. Use independent functional safety assessors to verify compliance and challenge designs. incompliancemag.com.
  3. Capture and analyse incidents such as sudden unintended acceleration; incorporate findings into design updates and hazard analyses.
  4. Require suppliers to align with ISO 26262; audit their processes and documentation.
  5. Supplement functional safety with SOTIF (ISO/PAS 21448) and cybersecurity (UNECE R155/R156) to address performance limitations and software updates.
