轿车追尾货车后气囊不能弹出问题的探析

Analysis on the Problem that Airbag Fail to Pop-up in Automobile Rear end Collision

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,导致前排驾来人员致死率极高。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。

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.
