摘　　要：开发了一种汽车主动安全技术的汽车自动紧急制动(AEB)行人检测系统。该系统包含软体假人目标、假人驱动装置及其控制系统,可按照2018版中国新车评价规程(C-NCAP)的AEB行人系统测试场景的要求,驱动假人目标行走,并可与操控测试车辆的驾驶机器人实时通讯。开展了对假人目标行走距离、假人目标行走速度和与驾驶机器人的联动实验。结果表明:该系统实验一次成功率达到90%以上,对假人速度控制的准确度96%,对假人与车辆碰撞位置的准确度达96%;该系统可准确复现行人危险工况。因此,该AEB行人检测系统可用于开展C-NCAP(2018)行人测试实验,作为车辆AEB系统功能评测及相关产品开发工具。An automatic emergency braking(AEB)pedestrian detection system was developed for automotive active safety technology.The AEB pedestrian detection system includes a soft dummy target,a dummy driving device and a control system with driving the dummy to walk according to the requirements of the AEB pedestrian test scenario of the2018Chinese New Car Evaluation Procedure(C-NCAP),with real-time communicating a driving robot which controls the test vehicle.Some measurements were done for walking distances of the dummy target,walking speeds of the dummy target,and linkage experiments with the driving robot.The results show that the success rate of the system is more than90%,while the accuracy of the dummy speed control is96%,and the collision location accuracy is96%.Therefore,the AEB pedestrian detection system can be used to conduct C-NCAP(2018)pedestrian test experiments both to evaluate a vehicle AEB system functions and to be a tool for related product developing since the system can accurately restore current hazardous conditions.
