摘要
为了建立符合中国交通状况和驾驶员驾驶行为的汽车自动紧急制动系统(AEB)完整的测试与评价方法,本文利用中国交通事故深入研究(CIDAS)乘用车事故数据,借鉴国内外研究成果,参考中国新车评价规程(C-NCAP)中的AEB行人测试方法,制定出符合中国国情的汽车自动紧急制动多种不同行人(AEB-P)测试工况。引入层次分析法(AHP)搭建AEB-P层次模型,确定了适用于测试和评价AEB-P测试场景及各场景对应的权重系数,利用自动驾驶仿真软件PreScan对所提测试场景进行建模。结果表明:通过引入碰撞时间(TTC)、相对距离和速度减少量作为AEB-P的评价指标并给予不同的权重,在PreScan中对提出的测试场景建模,提出的AEB-P测试与评价方法的合理性和实用性得到了验证。
A variety of pedestrians autonomous emergency braking system(AEB-P)test conditions was formulated to establish a complete test and evaluation method of autonomous emergency braking system(AEB)in line with China's traffic conditions and driver's driving behavior by using China in-depth accident study(CIDAS)passenger car accident data,drawing lessons from domestic and foreign research results and referring to AEB pedestrian test method in China new car assessment programme(C-NCAP).The AEB-P hierarchical model was established with introducing the analytic hierarchy process.And the weight coefficients was built up,which was suitable for testing and evaluating AEB-P test scenarios and the corresponding scenarios.The results show that the proposed AEB-P test and evaluation method are verified to be reasonable.
