Functional Safety Assessment of an Automated Lane Centering System

This report describes the research effort to assess the functional safety of a generic automated lane centering (ALC) system,. a key technology that supports vehicle automation by providing continuous lateral control to keep the vehicle Within the travel lane. This study follows the Concept Phase process in the ISO 26262 standard and applies hazard and operability study, functional failure modes and effects analysis, and systems-theoretic process analysis (STPA) methods. This study identifies 5 vehicle-level safety goals, 47 functional safety requirements (an output of the STPA process) for the ALC system, and 26 additional safety requirements (also an output of the STPA process) for the ALC system based on the results of the safety analysis. This study also uses the results of the analysis to develop potential test scenarios and identify possible areas for diagnostic trouble code coverage
