摘　　要：自动紧急制动(AEB)功能已成为国内外各汽车安全权威认证机构的重要评估点,但Euro NCAP、NHTSA、IIHS等认证机构发布的评估规程中涉及AEB的评价指标单一,无法对评估结果进行多维度解读。文章提出的基于层次分析法的AEB评价指标优化方法结合各认证机构建立的评价体系,分别采用定性分析与定量分析构建AEB评价指标优化模型,将安全性与舒适性作为评价准则,并以速度减量、最大减速度、碰撞时间(TTC)和减速度变化率作为评价参数,实现客观安全与主观驾乘体验相结合的多维度评估方案,优化了AEB评价体系。以CCRs某测试场景为例进行实际试验,验证了该基于层次分析法的AEB评价指标优化方案的可行性。The automatic emergency braking （AEB） function has become an important evaluation point for all domestic and international auto safety certification institutions. However, the evaluation index of Euro NCAP, NHTSA, and IIHS are relatively single, and evaluation results cannot be displayed in multi-dimension. The AEB evaluation index optimization method based on the AHP combines the evaluation methods of the certification institutions. In this method, safety and comfort are chosen as evaluation criteria, and speed reduction, maximum deceleration, collision time （TTC） and deceleration change rate are used as evaluation parameters, thus the multi-dimensional assessment model which combines objective security and subjective driving experience optimize the AEB evaluation system. Taking a test scenario of CCRs as an example, the actual test and evaluation are conducted to verify the feasibility of the AEB evaluation index optimization scheme.
