从致命车祸分析选择最安全车型
文章来源: Busdriver92019-03-15 08:23:45
Safety is defined as freedom from risk. If we avoid, reduce or eliminate risk we are safer.
It is important to realize that safety is relative. Eliminating all risk, would be extremely difficult and very expensive. When something is called safe, this usually means that it is safe within certain reasonable limits and parameters.(https://en.wikipedia.org/wiki/Safety)
美国公路安全保险协会(Insurance Institute for Highway Safety)测试类型最丰富是世界安全标准中最严格的,也是北美各保险公司依据的标准,除了基本的测试之外,IIHS还时常会进行一些特殊的碰撞,比如会进行车辆的对撞来评测安全性能,以及128km/h的时速撞向不可移动固体墙,但这也遭到了部分厂商的不满。正面碰撞测试,速度为64.4km/h; 侧面碰撞测试速度为49.8km/h
公车线路会覆盖所有繁忙路段(限速60km/h或50,40),所以我经常第一时间路过交通事故现场。T-Bone 碰撞形式居多,正面碰撞路冲房子,追尾或撞在树上属于打瞌睡或分心驾驶。现代各种车辆相对安全致死率较低是基于市内行驶条件,可通过防御性驾驶解决。

在实际交通事故中,并不一定按照理想碰撞测试条件进行。通常恶性交通事故只有出现死亡才会在新闻中看到,下列情况对司机致命而司机又无法控制:
 
1. 两车迎头对撞, 实际车速为两车速之和超过100KM/H。 车辆安全测试标准Euro NCAP 车辆测试速度 侧撞40KM/h,前撞64KM/H。从以下罗列新闻可看出:Unibody很大概率车毁人亡,Body-on-frame 型truck 人员基本安全。Head On Collisions  https://www.youtube.com/watch?v=FVoSp1SjrCw
 
2. 在高速公路上出爆胎事故,可能引起火烧车。原因是高速出车祸车体严重变形造成油箱破裂而Body-on-frame 型truck基本能预防此类油箱破裂事故,因为底盘的frame根本不会变形。Frame rails 最弱的C-shaped thickness from 1/8" to 3/16" 前几年我曾见过美国大雪暴后高速公路上车祸照片两辆 truck trailer 分别撞向一辆皮卡两侧, 皮卡上部完全变形司机只受擦伤。

总之,Body-on-frame型SUV是最安全的车(与皮卡共用相同底盘)。而且几百公斤重FRAME 可保证车重心低,不易侧翻。万一有不可避免的事故,只要刹车减速人体向车中心靠,伤亡几率大大降低。

保险公司很现实, 保费赔付人受伤费用占比例最大,所以Body-on-frame型SUV(truck)保费最低。当然保险公司根本不解释原因。
 
从汽车2019年1月加拿大销量数据也可看出消费者渐渐明白真正什么车型是安全车
passenger car 27,084   light truck 81,690  注:所有Body-on-frame车都叫truck

6. Car in deadly Port Credit crash 'exploded'
A car was torn apart following single car fatal collision along Lakeshore Rd E. near Stavebank Rd. in Mississauga, Ont. on Saturday, March 30, 2019
The Honda Civic came flying across the bridge over the Credit River around 2:30 a.m. like a rocket taking off. The driver, despite frantic paramedic and emergency room attempts to save him, was killed in this disturbing wipeout.
