摘　　要：汽车前撞预警系统(Forward Collision Warning System,FCWS)测距技术是高级驾驶辅助系统(Advanced Driver Assistant System,ADAS)的重要组成部分,其测距精度的高低直接关系到系统预警时间的安全裕度,影响车辆与行人安全。在详细分析FCWS各传感方案测距原理的基础之上,依据国家标准GB/T 33577-2017及交通运输行业标准JT/T 883-2014,针对某乘用车匹配的不同FCWS传感方案的测距精度进行了测试与评价。结果表明,毫米波雷达与摄像头信息融合方案的测距精度最优,同时指出了当前在汽车FCWS距离精度测评方面存在的一些问题并提出了相应的可行性建议。The automobile forward collision warning system(FCWS)ranging technology is an important part of advanced driver assistant system(ADAS). The high-accuracy distance measurement can provide sufficient warning time with adequate safety margin,improving the safety of vehicles and pedestrians. Based on the analysis of the distance measurement principles of various FCWS sensing schemes,the distance measurement accuracy of an automobile equipped with different FCWS sensing schemes was tested and evaluated in accordance with the traffic industry standard JT/T 883-2014 and the national standard GB/T 33577-2017. The test results show that the FCWS based on the information fusion of millimeter wave radar and camera leads to the best ranging accuracy. Meanwhile,the existing problems in the test and evaluation of the distance measurement accuracy of automobile FCWS were pointed out and the corresponding feasible suggestions were put forward.
