摘要： 高速公路发生追尾时对汽车破坏性巨大且人员伤亡率极高，为减少追尾事故带来的伤 害设计了一套汽车防追尾外置安全气囊预警系统。该系统通过数学模型来对危险进行判定分 析，采取安全距离预警、外置安全气囊点爆和安全带分级预紧三种措施，最大限度地卸去碰 撞时的冲击力。实现碰撞前预警，碰撞前提前约束人体，点爆气囊，在发生追尾事故时为乘 员提供最全面的保护。通过建立 CarSim 与 Simulink 的联合模型验证了系统的可行性。

Abstract: Rear-end collision on expressway is very destructive to cars and the casualty rate is very high. In order to reduce the injury caused, an external airbag warning system is designed. The system determines and analyzes the danger through mathematical model, and takes three measures, namely, safety distance warning, external airbag point explosion and seat belt pre-tightening, to remove the impact force of collision to the maximum extent. To realize pre-collision warning, pre-collision restraint of the human body, point explosion of air bags, in the event of a rear-end accident to provide the most comprehensive protection for the occupants. The joint model of CarSim and Simulink is established to verify the feasibility of the system.
