自适应前照灯系统论述

Discussion on Advanced Front-lighting System

自适应前照灯系统(Advanced Front-lighting System,简称AFS)主要是指在车辆在面对不同的路面状况时,前照灯的光型以及模组的角度能够自动地进行调整,使其照射出适应当前路况的光型,从而给客户带来更优质的照明。欧洲经济委员会(ECE)确立和定义了4种不同的基于AFS前照灯的工作模式,分别为C模式基础近光模式、V模式城镇模式、E模式高速模式和W模式恶劣天气模式,这4种模式的照明对单一的前照灯是一种非常好的补充和优化。本文在对ECE法规定义的AFS4种模式进行论述研究的同时,也详细介绍了动态AFS系统和智能灯光分布(MDF-Maskiertes Dauer Fernlicht功能)在实车方面的应用。

Advanced front-lighting system is that the headlamp can be adjusted automatically according to the different street status to get a good lighting shape on the street.ECE has already defined four different modes for AFS function.It is called Class C(Basic mode),Class V(City mode),Class E(High way mode)and Class W(Bad-weather mode).The four modes can bring an extra and better illumination for the front light system.This paper not only researched the four AFS modes which defined in ECE,but also introduced the application of dynamic AFS system and MDF(Maskiertes Dauer Fernlicht)system.
