摘要
针对现有汽车远光灯需要司机通过自身对路况的判断来完成手动操作,从而可能造成行车时因违规使用车灯而发生交通事故的问题,完成了基于不同路况和周围环境自动调节远光灯照射方式的矩阵式LED远光灯智能辅助控制系统的设计与实现。首先,根据车辆行驶特点及相关交通法规,针对不同的车前路况,提出矩阵式LED远光灯辅助系统的智能控制策略;然后,对系统的软硬件进行设计与实现,硬件部分主要包括主控制器模块、LED电源驱动模块以及矩阵开关控制模块的选型与电路设计,软件部分主要包括驱动电路控制、矩阵开关控制以及智能控制策略等功能模块;最后,在实验室环境下通过搭建完整的实验系统进行了功能测试。实验测试结果表明,所提方法控制结果准确、实时性好、可靠性高、易于实现,达到了预期目标。
Focusing on the problem that the existing car high-beam requires the driver to manually change the headlamp through his own judgment of the road condition, which may results in a traffic accident due to the illegal use of the high-beam, a matrix LED high-beam intelligent assistant control system which can automatically adjust the radiation way of high-beam according to the road condition and environment was designed and implemented. Firstly, according to the driving characteristics of vehicles and related traffic regulations, the intelligent control strategy of matrix LED high-beam assistant system was proposed for different road conditions. Then the hardware and software of the system were designed and implemented. In the hardware part, the device selection and circuit design of the modules like main controller, LED power driver and matrix switch controller were given, and the software part was composed of function modules like driving circuit control, matrix switch control and intelligent control strategy. Finally, a complete experiment system under laboratory conditions was built for functional test. The experiment test results indicate that the proposed method has accurate results and is steady, reliable, better in real-time and easy to realize, which achieves the expected goal.
