摘　　要：恶劣天气环境对自动驾驶系统的安全性能具有较大影响。针对自动驾驶汽车在强风环境下行驶安全性的测试验证需求,基于封闭测试场搭建了强风模拟环境,主要由横风测试跑道、横风风机阵列以及其他附属设施构成;然后基于构建的强风模拟环境进行了三种车速、两种风速工况下的自动驾驶汽车强风环境道路测试。测试结果表明,强横风环境下自动驾驶汽车会产生行驶偏移,强风风速越高,车辆行驶偏移越大;强横风对自动驾驶汽车激光雷达目标感知能力影响较小。Severe weather environment has great influence on the safety performance of automatic driving system.In view of the test and verification requirements for the safety of automatic vehicle under strong wind environment,a strong wind simulation system was built in a closed test field.The strong wind simulation environment is mainly composed of cross wind test runway,cross wind fan array and other ancillary facilities.Then,under the condition of three kinds of speed and two kinds of wind speeds,the performance test of the automatic vehicle was carried out by using the strong wind simulation environment.The test results show that the driving deviation of the automatic vehicle under strong crosswind will increase.Strong cross wind has little effect on the target detection ability of automatic vehicle base on lidar.
