ABS will reduce the breaking distance, because -

blueclue(blueclue)

本文发表在 rolia.net 枫下论坛It is true that ABS will not reduce the breaking distance under normal break situations, where the ABS does not kick in anyway. But things are different during an emergency break. Without the ABS, the tires will simply slip ahead because the break has completely locks them down. Once the tires slip, it becomes a pure friction between the road and the spot of the rubber that touches the road. With ABS, the tires are in a stop-rotate-stop circle. This leverages both the friction of the rubber, as well as the grasp abality created by the threads on the tires. With the tires rotation speed decreases, the force of the friction increases as a function of time. So the more speed you start with, the better breaking distance you will have. I've seen the breaking test from Chevy for the same car with and without the ABS before. That's what I learned from.

It's true that the situation is not always straightforward. But I think I've written more than what that URL has said, and warrants a better clarification. :-)

安全重要的话,ABS也就重要吧. -piaopiao(piao); 2001-6-20 (#106729@0)

刚从驾校学来的 -tomatoo(tomato); 2001-6-20 {483} (#107055@0)

在正常情况下,ABS并不起什么作用,只有在emergency的时候,ABS就会起作用了.
例如,当你遇到紧急情况(如地上有冰什么的)需要刹车时,当你踩刹车后,如果没有ABS,就会造成四轮锁死的现象,那时你就无法通过方向盘来控制轮胎来转向,这样就可能车子打转什么的.当然师博会教,要脚一踩一放,但是人脑的反应没有机器快,所以当有ABS的时候,它会帮你做到脚一踩一放的效果,这时你就可以通过方向盘来控制方向,车子就不会冲出公路或是别的什么了.

申明,本人不是高手,只是昨天才上了第一堂学车课,课上听来的就写下来了,不对的请多多指教

You are right. ABS is only useful on wet or slippery road. It has no effect on dry clean road. In fact, it will make the break distance longer than without it. -hailstorm(鹏飞北溟); 2001-6-20 (#107095@0)

不对呀,驾校老师说,有ABS和没有ABS的车刹车后的距离是相差无几的.所以无论有没有ABS都要与前面的车保持足够的车距 -tomatoo(tomato); 2001-6-20 (#107100@0)

错，有ABS的刹车距离长。但不容易侧滑。刹车时稳定性非常重要，尤其是冬天。北京雪天经常看到小面刹车后车都横过来了。不知现在还有小面不？ -chipmuck(花栗鼠); 2001-6-20 (#107670@0)

Yes, more attention should be payed to the break distance if ur car has ABS. -tweety(RedMenace); 2001-6-20 (#107139@0)

是不是这样： -fxid(枫下客); 2001-6-20 {325} (#107062@0)

I think you will need it if you plan to drive in winter. It saved me when I drove on 401 last December. It was my first time to drive in heavy snow. I can never forget it. -tweety(RedMenace); 2001-6-20 (#107069@0)

请讲讲详细情况，对我等也是个教训。 -rollor(Rollor); 2001-6-20 (#107078@0)

It was the first heavy snow in the last winter. -tweety(RedMenace); 2001-6-20 {691} (#107114@0)
It was the first heavy snow in the last winter. The snow on some segments of 401 was not removed at that time, esp one segment near Milton. Some places were even covered with solid ice. The car in front of me brake suddenly and slipped from left to right. I hit my brake too. (I forgot that I should pump the brake in stead of hit it at that moment. ) Suddenly I felt the jolt from the brake pedal. It was the ABS! And my car was ok, straight ahead in the middle lane! I really thank my LG made the decision when we bought that car.

btw, when u drive on snow or icy road, you'd better pump the brake in stead of hit it, if you dont have ABS. Plus, have a good control of your wheel. :-)

很重要，特别是冬天，特别是你开车技术不太熟练时。当然我用不着，呵呵。 -guest:expertune; 2001-6-20 (#107070@0)

ABS可以买车时不要,以后需要时再加么?还有其他的options,比如空调什么的? -goodbaby(小宝); 2001-6-20 (#107098@0)

个人认为,空调一定要的,否则夏天坐在车上会很热的,特别是当车在太阳下晒了几个小时的时候! -tomatoo(tomato); 2001-6-20 (#107102@0)

new drivers need ABS! very important! -hhll26(likeplay); 2001-6-20 (#107151@0)

Check this site. A very detailed introduction about ABS -hailstorm(鹏飞北溟); 2001-6-20 (#107246@0)

Up???? -hairless(亮晶晶); 2001-6-20 (#107625@0)

Egg? Danny? 激昂?怎么都不出来? -hairless(亮晶晶); 2001-6-20 (#107689@0)

有ABS当然好了，没有的话，冰雪路小心一点也能过。我不是开了5-6年车了吗，基本上都是没有ABS的车，出过事故，但当时的情况有ABS也未必能避免。有钱就加上，没钱就不加，马路上的车有ABS的比例有多大？一半？ -eglington(eglington); 2001-6-20 (#107703@0)

OK, Thanks. You're pretty nice. 习习习 -hairless(亮晶晶); 2001-6-20 (#107721@0)

出于安全方面考虑是有必要的。因为我们每天都要上下班，交通事故是存在的最大的隐患，我觉得这方面的钱不应该省。我还有一件臭事呢。。。 -mike2000(peter); 2001-6-20 {391} (#107690@0)

我到车行去买车，想试一试ABS，于是就开着车行的车上路了，当我开到一段车少的路段时，就来了一个急刹车，我的车稳稳当当地停下了，这时，从后面传来一阵急刹车声，一辆小货车冲上了马路牙上。原来我忘了看后镜，是我的错。如果他不开上马路牙，肯定会撞上我的车。于是我又点头又赔不是，好在那个司机也是一个好脾气，嘴上小生唠吧唠叨了几句(我听不清楚，我想他肯定是骂我呢）就开走了。我呢，当然就买了有ABS功能的车。

我觉的没用。 -jimmyzxz(jimmie); 2001-6-20 (#107741@0)

据说，小车，如CIVIC, COROLLA, SENTRA有必要，大一点的没用。 -roliacanada(Rolia); 2001-6-20 (#107754@0)

A very important safety feature. It helps 1) drastically reduce the breaking distance; 2) maintain traction during emergency break; 3) maintain traction breaking on a slippery road. All of them are vital to a modern car regardless of its size. -blueclue(blueclue); 2001-6-21 (#107802@0)

1) is not correct. See#92740 -hearts(hearts); 2001-6-21 (#108374@0)

你是在拿ABS和不起作用的煞车比较，明白了。多谢。 -hearts(hearts); 2001-6-21 (#108601@0)

Anybody checked the site in post #107246 ? All the questions have been answered. It's from Transport Canada. Do you guys ever read English posts? -guest:; 2001-6-21 (#108393@0)
