广西工学院鹿山学院本科生毕业设计（论文）五菱荣光汽车大灯自动控制系统的改进摘 要汽车远光灯是为了让驾驶者在夜间高速行驶时看清远方路况，但是在会车时如果不及时切换到近光，其强烈的光线会使对面车辆无法看清道路，极易发生交通事故。根据国内交通事故统计， 在夜间发生的交通事故中， 与远光灯有关的事故占到近四成，并且成上升的趋势。 本文是通过在五菱荣光汽车前大灯控制电路中加入一套容易实现的自动控制系统。当在夜晚行车远光灯打开时，系统能通过光检测输入模块检测前方是否有相对方向的较强光源，若有则激活自动变光模块，切断远光电路并接通近光电路。能很好地解决传统方式下， 手动变光不及时和驾驶员因疏忽忘记切换近光等问题，从而大大减少事故的发生。关键词：汽车前照灯；光敏电阻；晶体三极管；自动变光；Wuling Rong Guang improvement of the automatic control system of the car headlights Abstraet The automobile headlights on full beam to let driver see clearly the distant place state of roads when the night high-speed travel, but when passing in traffic, if not cut the headlight low beam promptly, its intense ray will keep the opposite vehicles from seeing clearly the path, is extremely easy to have the traffic accident. Counts according to the domestic traffic accident, in traffic accident that the night has, occupies with the headlights on full beam related accident about 40%, and becomes the trend of rise. This article is by WulingRongGuang car headlights added a set of easy to implement automatic control system to control circuit. When driving at night lamps turned on, detection through the system input module detection in front of the relative orientation of a strong light source, if you activate automatic dimmer module, cutting off remote optical circuit and turn on photoelectric road. Can be a very good solution to the traditional mode, manual light not on time and the driver inadvertently forgot to switch o...
