<>谁知道怎样从刹车距离判断车速,,,或者从车速算刹车距离,是否有相关的公式,???跟车的自重有关系吗</P>
<>谢了 </P>

在1秒钟里,如果你的时速大约是100公里,那么刹车距离应该是30米;80公里刹车应该是22米。而实际情况下:从发现障碍物,经过反应时间到把脚放到刹车踏板上,因人而异,大约需要1~2秒。各种因素一集合,刹车距离会增加2~3倍。SO:如果车速为100公里/小时,就应该与前方车辆保持130米,就没有危险因数;如果车速为80公里/小时,你就应该保持100米距离没有危险因数!<BR><BR>&nbsp;&nbsp;以上观点取自老司机以及一些汽车画报,当然刹车距离越远越好:P,废话!<BR>&nbsp;&nbsp;大家也可以仁者见仁智者见智,发表自己的高见,或者因为刹车距离引发的一些故事!更可以杜撰,寓教于乐! <BR>
