Safety of the Intended Functionality of Lane-Centering and Lane-Changing Maneuvers of a Generic Level 3 Highway Chauffeur System

This report describes the findings from applying Safety of the Intended Functionality (SOTIF) concepts as described in the Publicly Available Specification (PAS) ISO 21448 to the lane-changing and lane-centering maneuvers of a generic Level 3 highway chauffeur system. This report compares the SOTIF process described in PAS 21448 with the automotive industry’s voluntary functional safety standard, ISO 26262. This report then develops a generalized Level 3 highway chauffeur system, and identifies potential vehicle-level hazards, triggering events, and SOTIF mitigation measures. Finally, this report presents an approach for developing candidate scenarios to evaluate safety relevant triggering events and discusses current SOTIF evaluation approaches.
