摘　　要：为探究自动紧急制动(AEB)系统在事故场景中的避障作用,基于中国交通事故深入研究(CIDAS)数据库,分析了乘用车与两轮车事故成因及典型场景,确定其分布特性,建立了碰撞前1 s两轮车与乘用车的相对位置分布情况,基于此对自动紧急制动系统进行了工程探索,结果表明,两轮车被检测到的概率随自动紧急制动系统视场角的增大而增大。对真实道路行驶数据的研究表明,电动自行车在与乘用车同向或反向行驶时易被识别为摩托车,横穿场景易漏检或归类为行人。To investigate the effect of obstacles avoidance of Automatic Emergency Braking(AEB) system in collision avoidance scenario, cause of car and two-wheeler accident and typical scenario based on China In-depth Accident Study(CIDAS) database are analyzed, determine the position distribution characteristics are determined, the relative position distribution of the two-wheeler and car 1 second before collision is established, and engineering exploration to AEB system is made. The is established results indicate that the possibility of two-wheeler to be detected increases with the field-ofview of AEB system. The research on real road driving data shows that, electric bicycle is easily detected as motorcycle when it drives in the same or the reverse direction as the car, the scenario of traversing is easily undetected or classified as pedestrian.
