摘要
基于汽车追尾真实事故形态分析,通过汽车碰撞事故分析系统,在充分考虑人-车-路复杂交通环境和我国驾驶员个性特征的前提下,对最小安全距离和危险距离进行了重新界定和量化。在此基础上创新地提出了追尾避撞的新算法。并应用Visual Basic 6.0编程软件进行了模拟仿真和数据分析,验证了建立在真实事故基础上的追尾避撞算法的可行性。试验表明,改进的算法既能有效地提高道路交通效率,又可减少或避免汽车追尾事故的发生,为汽车主动防追尾系统的普及应用提供了理论依据。
Based on the morphological analysis of real-world rear-end collision accidents, the re-definition of and quantitative analysis on minimum safe distance and dangerous distance are performed with full consideration of domestic drivers＇ individual characters and the complex road-ear-driver traffic situations. Then, a novel algorithm for avoiding rear-end collisions is proposed. To verify the feasibility of the presented algorithm, emulation and data analysis are performed by Visual Basic 6. O. The experimental result shows that the improved approach is capable of enhancing road traffic efficiency and reducing and! or avoiding rear-end collisions, which could be a reference for popularizing the active collision accident avoidance system.
