Abstract:
Electronic stability control (ESC) systems have been the subject of statistical analyses of road accidents, testing by NHTSA and others, and Federal Motor Vehicle Safety Standard 126 scheduled to be effective in 2011. ESC systems employ complex algorithms to process information from multiple sensors and intervene to improve vehicle directional control. They are called upon to function under conditions of varying road coefficients, grade, vehicle load, and driver inputs. In this study, Engineering Dynamics Corporation SIMON modeling software was used to examine ESC system responses to a variety of factors. ESC system effectiveness was found to be sensitive to split coefficient conditions, driving surface irregularities, braking, and specific driver inputs.
