Abstract:

This report describes the research effort to assess the functional safety of electric power steering (EPS) systems. This study also considers the additional active steering and four-wheel steering features, which are incorporated into some EPS systems. 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 methods. In total, this study identifies four vehicle-level safety goals and 125 EPS system safety requirements (an output of the ISO 26262 process). This study uses the results of the analysis to develop potential test scenarios and identify possible areas for diagnostic trouble code coverage.
