夜间车辆远近灯光强制切换设计

Forced Switching Design for Vehicle High/Low Beams at Night

由于在夜间行车远光灯炫目易导致交通事故,文章设计了一种汽车前大灯远近灯光强制切换系统,可在会车时自动切换远近光,当传感器测到对向射出光照强度大于一定值或与对向车辆距离小于一定值时即发送指令到控制单元进行远光强制切换成近光的操作,避免由于本车远光灯开启对他人造成的炫目,会车结束后再切换成远光,保证夜间行车安全。

Since the dazzling headlights can easily lead to traffic accidents when driving at night,this article designed a forced switching system for high and low beams of car headlight,which can automatically switch the high and low beams during the car crossing,when the sensor measured the opposite incoming light intensity being greater than a certain value or when the distance from the opposite vehicle is less than a certain value,it will send an instruction to the control unit for the forced switching from a high beam to a low beam,avoiding the glare to other people caused by turning on the high beam of the own vehicle and then it will switch back to high beam after the car crossing,so as to ensure traffic safety at night.
