关 键 词：vehicle braking performance roadway test evaluation methods
摘 要：Service braking test and evaluation are of importance for vehicle braking *** vehicle braking performance roadway test system was firstly designed in the paper,whose main instrument was GPSbased VBOX *** the systematic vehicle braking performance tests were conducted on the vehicle proving *** on the real straight-line braking test data,two indexes,braking distance and mean fully developed deceleration (MFDD) according to rules and regulations for braking performance test,were analyzed respectively and *** results shows that,MFDD index can avoid the effect of driver s operation or braking system reaction time on braking performance,so this evaluation method is more ***,braking distance index reflects the comprehensive effecting of human-vehicle system and obtains the integrated evaluation.
