摘要:目前我国交通事故多发,死亡人数上升,其中汽车高速追尾是交通事故的主要形式之一,尤其是在小轿车与大货车追尾撞击时,轿车被撞击部位大多位于轿车A柱中间部位,而轿车的撞击传感器均安装在车头前面页板处和两侧B柱下半部,不在撞击区间,因此轿车内的安全气囊不能弹出,导致前排驾乘人员致死率极高。为解决这一问题,提出在轿车被撞击的部位加装安全气囊碰撞传感器,从而保证安全气囊有效弹出,避免追尾事故中的人员伤亡事故发生。

Abstract:In our country, the traffic accidents happen frequently and the death toll rising, one of the main forms of traffic accidents is caused by automobile rear end collision. Especially, when a small car bump into a large truck and the airbag fail to pop-up, since the impact position of car is usually located in the middle of the A-pillar of the car, however, the crash sensors are not installed on the impacted region, they are installed on the front of car plate and the lower parts of the B-pillars on both sides. In rear-end collision, the death rate of the driver and passenger in the front row is very high. In order to solve this problem, crash sensors for airbags are suggested to be installed on the positions where the car may be bumped, the sensors can ensure the airbags be effectively pop-up and then the avoid the casualtyaccidents in rear end collision.
Key words: car, rear-end collision, crash sensor, airbag
1 引言:
随着我国社会经济的高速发展,人们拥有汽车的数量迅速增加,交通事故也随之不断增多。在众多的交通事故当中,有一种交通事故与其他交通事故相比可以说更加令人感到痛心,就是小轿车追尾大货车后,轿车前部直接钻进大货车尾部下面,从而导致轿车内的驾乘人员死亡。根据相关资料统计,小轿车追尾大货车事故约占到追尾交通事故的50%,其致死比例是轿车与其他车型碰撞致死比例的四倍。如此严重的后果主要是小轿车追尾大货车后,小轿车内的安全气囊不能及时有效地弹出而造成的。
