摘要
随着智能汽车的普及和人们对车辆安全性的重视,越来越多的车辆上配置了平行显示系统(HUD)。HUD是通过平行显示装置把时速、导航等重要行车信息投影到车辆前风挡玻璃上,让驾驶员的视线尽量放到行驶道路上,提高驾驶员在行驶中的安全性。HUD在工作中会受到电磁干扰的影响,因此HUD在电磁环境中的可靠性和安全性同样引起重视。本文主要讲述HUD的电磁兼容测试方法,并分析如何改善HUD在电磁环境中的抗扰能力。
With the popularization of intelligent vehicles and people's attention to vehicle safety,more and more vehicles are equipped with head-up display(HUD).HUD projects such important driving information as speed and navigation on the front windshield of the vehicle through parallel display device,so that the driver's line of sight can be put on the driving road as far as possible to improve the driver's safety in driving.HUD will be affected by electromagnetic interference in work,so the reliability and security of HUD in electromagnetic environment also arouse attention.This paper mainly describes HUD's electromagnetic compatibility testing method,and analyzes how to improve HUD's anti-disturbance ability in electromagnetic environment.
