摘　　要：随着汽车自动驾驶技术的发展,为了达到更高的安全冗余,车辆对环境感知提出了高精度的要求。激光雷达作为新型车载高精度三维感知传感器,是实现高阶自动驾驶的关键传感器。车载激光雷达采用飞行时间法来实现对目标的位置、反射率等信息的感知,经过近几年的技术迭代,已经实现了量产装车。相对于毫米波雷达、摄像头和超声波雷达,激光雷达功耗和体积都较大,目前的安装位置通常选择在车顶,这种安装位置会对整车的外观造型和风阻带来影响,将激光雷达集成于车灯之中,成了解决激光雷达安装位置的一种技术方案。本文从当前激光雷达和车灯技术发展趋势出发,对车载激光雷达及其车灯集成进行技术分析,探索车灯集成激光雷达的可行性。With the development of autonomous driving technology,in order to achieve higher safety redundancy for vehicle occupants,vehicles have put forward high-perception requirement for environment perception.As a new type of vehicle-mounted high-perception three-dimensional perception sensor,LiDAR has become a key sensor for realizing high-level autonomous driving.LiDAR uses the time-of-flight method to sense the spatial coordinates,reflectivity and other information of objects.Based on several years of technology iteration,mass production applications have been achieved.Compared with millimeter-wave radar,cameras and ultrasonic radars,LiDAR has larger power consumption and volume,and its current installation location is usually on the roof of the vehicles.This installation location will affect the appearance and wind resistance of the vehicle,and integrating LiDAR into vehicle headlights has become a technical solution to solve the installation location of LiDAR.In this paper,based on the current development trends of LiDAR and vehicle headlights technology,we conduct a technical analysis of vehicle LiDAR and its headlights integration,and the feasibility of integrating LiDAR into car lights.
