摘　　要：提出一种测量倒车雷达探测范围的方法,利用激光器、激光测距仪及三坐标测量机结合超声波雷达的原理,通过光滑拟合雷达最远探测点的方式,可视化显示倒车雷达探测范围,经过试验验证该方法的测量准确度为2%,最后利用该方法确定倒车雷达在视野盲区内为不同障碍物提供的有效探测范围。该文通过将整车上的倒车雷达复制到台架上的方式测量倒车雷达的探测范围,为国内尚不明确的倒车雷达测量范围测试标准提供参考。This paper has proposed a method to measure the detection range of reversing radar by using a laser,a laser distance meter and a coordinate measurement machine. Specifically,fit the farthest position that radar can detect smoothly with the operating principle of ultrasonic radar to visualize the detection range of reversing radar. The measurement accuracy was verified to be 2%.The last step was determining the effective detection scope provided by the reversing radar in blind spot vision to different obstacles. Particularly, the radar system installed on vehicle was reverted to a test bench to measure the detection range. The method offers a reference for domestic standards that are still indefinite for the measurement range of reversing radar.
