摘　　要：汽车传统物理后视镜不仅存在盲区大、看不清、干扰大、风阻大问题,而且结构外形较大,风阻大,油耗和电耗也随之增大。为此,本文研究了汽车电子后视镜的重要性及技术方向,遵循国标提出一种基于FPGA系统的汽车电子后视镜方案,整机时延30 ms以内,开机时间≤1 s,支持故障检测、转向灯、折叠、角度调节等,整机满足国标的19个技术要求。汽车电子后视镜具有等同于或更优于物理后视镜的相应功能,确保了驾驶员的驾驶体验。Traditional physical rearview mirrors in automobiles have four major problems:poor blind spot,unclear visibility,high interference,and high wind resistance.Moreover,their structural shape is large,with high wind resistance,resulting in increased fuel and electricity consumption.This article studies the importance and technical direction of CMS,and proposes a CMS solution based on FPGA system in accordance with national standards.The whole machine has a delay of less than 30 ms,a startup time of≤1s,supports fault detection,turn signals,folding,angle adjustment,etc.The whole machine meets 19 technical requirements of the national standards.The CMS has corresponding functions equivalent to or better than physical rearview mirrors,ensuring the driver's driving experience.
