摘要
针对交通事故多发生在夜间或光线不充足的情况,提出一种在现有汽车照明系统中增加近光灯随动系统,有效增加驾驶员的视野范围。设计了一个自适应模糊控制系统,采用自适应系统和模糊控制算法相结合的方法,将方向盘的转动角度模糊化后进入控制系统。实现当汽车转弯时,通过判断车前轮转动的角度,控制器控制车灯亦随车前轮转动的方向转动相同的角度;在车轮的转角小于一定值时车灯的方向自动复位。系统测试结果表明,在汽车转弯时本系统能有效增加驾驶员的视野,即在转弯时驾驶员的视角保持在75度以上,大大减少因转弯驾驶员的视角变窄而发生的交通事故。
While at night or the light not being sufficient, traffic accidents are more likely to happen. Put forward one kind of the lamp tur- ing with move of steering wheel, it doesn＇t change the car lighting system, effectively increase the driver＇s vision scope. Design a adaptive fuzzy control system, combining adaptive system with fuzzy control algorithm, it can convert the angle of steering wheel into fuzzy varia- bles and input to the control system. While the car turns,by judging the angle of the car wheel rotation,the system can control the light al- so turning the same angle. As the corner of the wheel is less than certain v＇,due, the direction of the light can automatically reset. After tes- ting, when car is turning the system can effectively increase the driver＇s vision, during turning it can keep the driver＇s perspective is in 75 degrees above, greatly reduce the opportunity of the traffic accident.
