A REPEATABILITY EXAMINATION OF NHTSA'S PROPOSED FMVSS 126 ESC EVALUATION METHOD AND METRICS

摘要

NHTSA's proposed FMVSS 126 ESC evaluation method and performance requirements are repeatedly tested by three vehicle manufacturers and NHTSA using two vehicle configurations, five test sites (tracks) and three temperature ranges. The results are examined to determine the sources of variability. Conclusions are presented on the variation of observed results. The initial experiment was designed considering directional stability metrics. The scope of the study was later expanded to include the responsiveness metric.
