。。。也是在QEW,也是租车,略有不同的是由大瀑布返程的路上,都到CNE了,咔嚓轰隆一下,左前胎爆了~~~ 咔嚓是俺想像的轰隆一声是车子撞到马路牙子了;还好虽然俺是刚拿到牌照2天,不过天生的临危不惧,没有急踩刹车。。。大家都是150的速度喂~,多伦多疯狂吧?。。。车子慢慢停下,后面所有的车也都停下了,俺再慢慢晃到右边紧急停车道,打电话给给租车公司报告,人家第一句话不是问人伤了没有是问报告警察了吗?俺反应贼快的说“yes", 对方沉默2秒,说等着给你拉辆新车。。。二十分钟后新车如约被拖车拉到。冰蚁 发表于 2013-6-20 12:06
abs 是防这种抱死,用的方法包括 threshold braking 和 cadence braking 。threshold braking 就是尽量 ...
请指教
时速150是迈还是公里?Braking beyond the slipping point causes the tire to slide and the friction adhesion between the tire and driving surface is reduced. The aim of threshold braking is to keep the amount of tire slip at the optimal amount, the value that produces the maximum frictional, and thus braking force. When wheels are slipping significantly (kinetic friction), the amount of friction available for braking is typically substantially less than when the wheels are not slipping (static friction), thereby reducing the braking force. Peak friction occurs between the static and dynamic endpoints, and this is the point that threshold braking tries to maintain.




所以如果施加的刹车压力始终保持在轮子滚动时的最大摩擦力矩那一点上,就可以产生最大的摩擦力,来获得最小的刹车距离。
