汽车防碰撞系统是汽车主动安全的关键技术之一,而预警/碰撞(CW/CA )算法又是汽车防碰撞系统的核心。对已有的几种预警/碰撞算法进行了分析,并利用Berkeley模型对比分析了分别考虑驾驶模式和驾驶员驾驶特征情况下预警算法的准确性。结果表明,基于驾驶员驾驶特征的预警模型更能满足实时预警要求、降低虚警率。最后,分析了当前预警/碰撞算法存在的问题。

Automotive collision system is one of the key technology of the vehicle active safety , and collision warning/collision avoidance (CW/CA) algorithm is the core of the automotive colli‐sion system .In this paper ,several existing collision warning/algorithms are analyzed , then the accuracy of the warning algorithm is contrast and analyzed using the Berkeley model ,under the consideration of driver's driving patterns and driving characteristics .The results show that the w arning model based on the driving characteristics could satisfy the requirement of real‐time warning ,and reduce the rate of false alarm .At last ,the problems existing in the current colli‐sion/warning algorithm are analyzed .
