商用车辅助驾驶系统感知传感器特性及选型分析

Analysis of Characteristics and Lectotype of Perception Sensors for Driver Assistance System of Commercial Vehicle

汽车辅助驾驶系统是在感知传感器对道路环境进行感知的基础上对驾驶过程中的潜在危险进行预警提醒或主动控制干预。近年来中国交通部以商用车应用为试点,发布相关法规逐步强制推行辅助驾驶系统的配备,以切实提升商用车的安全性。感知传感器是辅助驾驶系统的重要基础,本文在充分分析视觉、毫米波雷达、激光雷达的基础上,综合考虑实际应用对性能和成本两个方面平衡的需求,给出了不同应用传感器的选型建议,为商用车辅助驾驶系统的传感器选型提供参考。

Driver assistance system is working to reduce accident risk by triggering warning or actuation based on perception sensors to obtain the road environment informations.Recently,China transportation department release some regulations to mandate the installation of driver assistance systems before market,especially,for the commercial vehicle manufacture so as to improve the safety of the vehicles.Perception sensors are the most important foundation of driver assistance system,so in this paper,characteristics of camera,radar and lidar are analyzed.Furthermore,from the perspective of the mass production application of drive assistance system for the commercial vehicle,performance and cost are both considered,on the basis of which,lectotype of perception sensors is suggested for the reference of OEM.
