Functional Safety Assessment of a Generic, Conventional, Hydraulic Braking System with Antilock Brakes, Traction Control, and Electronic Stability Control

This report describes the research effort to assess the functional safety of foundational braking systems, specifically focusing on conventional hydraulic braking systems that includes antilock brakes, traction control and electronic stability control, which are typically included in current generation vehicles. This study follows the concept phase process in the ISO 26262 standard and applies a hazard and operability study, functional failure mode effects analysis, and systems theoretic process analysis methods. In total, this study identifies eight vehicle-level safety goals and 198 CHB system functional 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.
