夜间行驶的车辆相会时，很多驾驶员由于疏忽或者缺乏会车常识而不进行远近光灯的切换，带来了很大的安全隐患。结合光电检测技术、坡路检测技术、路况智能检测技术，设计实现了汽车远近光灯智能切换系统。试验表明，该系统可以灵敏地实现夜间行驶在坡路、拱桥、人行横道等路段时的自动远近光交替闪烁功能，在会车时也可以准确地实现远近光灯的切换。%Since many drivers do not switch their far and near light of headlights due to their negligence or lack of the meeting common sense in the process of night driving,which may cause serious security risk,an intelligent headlight switching system based on the technologies of photoelectric detection,ramp detection and road condition detection was designed. The experimental results show that the system has the functions of automatic alternating flashing of far and near light when running through ramp, arch bridge and pedestrian crossing,and automatic switching of the far and near light when meeting other vehicles,so as to avoid the occurrence of traffic accidents.
