1、 本科学生毕业设计 汽车前照灯防眩目控制系统的设计 系部名称： 汽车与交通工程学院 专业班级： 车辆工程 B07-1 班 二一一年六月 The Graduation Design for Bachelors Degree Design of Cars Headlamps Prevent blindfold Control System I 摘 要 随着社会的发展和人们生活水平的不断提高，人们对汽车的要求已不仅仅局限于 性能、成本，而是越来越多的要求现代汽车更加安全，更加环保，更加人性化。而同 时，新车款型也必须符合最新的规定，这就导致了新技术不断得到应用。作为汽车的 三大安全件之一，汽车照明系

2、统是最主要的主动式安全装置，对传统汽车照明系统的 改进和创新也日益成为全世界汽车厂商研究的热点问题。为此，设计了以单片机为核 心，实现汽车前照灯防炫目的系统的控制。 前照灯防眩目系统主要有硬件和软件俩部分组成。硬件部分主要有电位器，单片 机和舵机。电位器的电阻值可以变化，可以当作信号。单片机是控制器，把电位器传 来的信号转换成舵机能识别的信号。舵机是执行器，它接收到单片机的信号后可以转 动相应的角度。系统工作方式是电位器把信号传给单片机，单片机经过处理把信号转 换后传给舵机。软件方面就是先把单片机的各个寄存器设置好，再把接受信号的 AD 口设置好，还有是控制舵机的 PWM 输出口。最后根据硬件

3、把软件的各个程序段连接起 来，使其正常工作。此设计中的介绍了基于 STC12C4052AD 单片机的汽车前照灯防炫目 控制的设计。 关键词关键词：前照灯；防炫目；ST12C4052AD；舵机；调试 II ABSTRACT With the development of the society and the continuous improvement of peoples living standard, people on the requirements of the car has not only confined to performance, cost, but more and

4、 more requirements modern car safer, more environmental protection and more human. And at the same time, the new car should also must comply with the latest regulation, this has led to a new technology to get the application. As the big three auto safety thing, automobile lighting systems is one of

5、the main active safety device, to the traditional automobile lighting system improvement and innovation also has become a hot spot in the study of the world automobile manufacturers. Therefore, the single-chip design as the core, and realize the automobile lamps glaring system control. The system is

6、 mainly a headlamp blinding hardware and software both parts. Hardware mainly potentiometer, SCM and steering gear. Resistance can change the potentiometer, can be as a signal. A single chip computer is the controller, the signal conversion from potentiometer into steering gear can identify signal. The steering gear is the implementation, it receives SCM signal after can turn the corresponding Angle. The system is the signal potentiometer working way to microcontroller, SCM processing
