摘　　要：普通平面内后视镜因反射率单一,不具备防眩目功能;手动防眩目内后视镜通过楔形镜片设计实现手动防眩功能;电子防眩目内后视镜利用光敏电阻检测汽车前后方光线强弱,控制改变镜片反射率实现自动防眩目功能;流媒体内后视镜借助安装在汽车尾部的广角摄像头,将车后的信息显示在后视镜上的显示屏上,基本扫除车后盲区。通过对各种型式内后视镜的结构与功能实现进行分析,为不同档次定位的车辆内后视镜选型提供了依据。The in-plane rearview mirror does not have the anti-dazzling function because of the single reflectivity. The manual anti-dazzling rearview mirror is designed by the wedge lens to realize the manual anti-dazzling function. The electronic anti-dazzling rearview mirror uses photosensitive resistance to detect the strength and weakness of the front and back light of the car, and control the reflectivity of the lens to realize the automatic anti-dazzling function. The streaming media rearview mirror displays the information on the rear view mirror with the help of the wide-angle camera installed on the rear part of the car, and basically eliminates the blind area behind the car. In this paper, the structure and function of various types of rearview mirrors were analyzed, which provided a basis for the selection of interior rearview mirrors for different grades of vehicles.
