| Abstract | This report describes the research effort to assess the functional safety of accelerator control systems (ACSs) with electronic faults, such as errant electronic throttle control (ETC) signals, following an industry process standard. This study focuses specifically on errant signals in motor vehicles powered by gasoline internal combustion engines. This study follows the concept phase process in the International Organization for Standardization (ISO) 26262 standard and applies a hazard and operability study, functional failure modes and effects analysis, and systems theoretic process analysis (STPA) methods. In total, this study identifies 5 vehicle-level safety goals and 179 ACS/ETC system safety requirements (an output of the ISO 26262 and STPA processes). This study uses the results of the analysis to identify potential opportunities to improve the risk assessment approach in ISO 26262. |
