一种防追尾安全系统的控制方法

A control method of rear-end anti-collision security system

从保障行车安全的角度提出一种防追尾安全系统,利用电磁同性相斥原理,当前车减速或急停时,通过磁力来增大后车的减速度,并通过比较安全作用时间的大小来决定电磁装置的开与闭,形成自动辅助刹车系统。其目的是避免驾驶员的反应迟滞,在第一时间保证车辆安全,提高后车在危险情况下制动的减速效率,另外,从安全距离和减速度效率两个方面分析了系统的可行性并给出了控制策略。

This paper puts forward a rear - end anti - col- lision security system from the point of view of ensuring the traffic safety. The method uses the principle of elec- tromagnetic repulsion of the same. When the leading ve- hicle suddenly slows down or has an emergency stopping, the following vehicle increases its deceleration by themagnetic force, and then it opens or closes the electro- magnetic device by comparing the time value with the set- ting value to set up an automatic auxiliary braking sys- tem. The purpose of the system is to avoid the driver＇ s reaction delay and ensure the car safety immediately. At the same time, it can improve the efficiency of decelera- tion. This paper analyses the feasibility of the method from two aspects： safety distance and deceleration effi- ciency, then describes the method of controlling.
