一、对各国车辆制动减速度值和平均减速度值缺乏可比性的计算分析车辆制动性能与交通安全关系至密,故各国都对此作了严格的考核规定。制动减速度和平均减速度就是评价汽车、汽车列车、拖拉机和拖拉机挂车机组制动性能的重要指标之一。然而,从各国标准对制动减速度和平均减速度所下的不同定义来看,其涵义的差别是很大的。这就造成了同一术语其概念并不等同,同一数值实际具有不同的等效量值这样的现象。
First, the calculation of vehicle brake deceleration value and average deceleration value of the lack of comparability of the vehicle braking performance and traffic safety are closely related, so all countries have made strict assessment requirements. Braking deceleration and average deceleration are one of the important indicators to evaluate the braking performance of automobile, train, tractor and tractor trailer units. However, according to the different definitions of braking deceleration and average deceleration under different national standards, the differences of their meanings are great. This results in the phenomenon that the same term does not mean the same concept and that the same value actually has a different equivalent amount of value.
