基于汽车雷达的弯道行驶车辆防撞算法

摘要

本文提出了一种汽车雷达弯道防撞算法，首先利用 Hough 变换在雷达的距离-方位观测结果中提取道路边界，再根据目标车辆与本车相对于道路边界的位置确定两车是否位于同一车道，进而判断两车是否可能发生碰撞。算法能够有效提升雷达在汽车弯道行驶时的工作性能。%An automotive radar based novel anti collision method in curve lane is proposed. Firstly, the lane boundary is extracted by using Hough transform technique. Then determine whether a target vehicle is in the same lane with the host vehicle on the basis of their relative distance to the road boundary; finally further judge if these two vehicles may cause collision. This method can improve operation efficiency of the automotive radar in curve lane.
