基于AT89S52单片机的汽车尾灯控制器设计

为了减少交通事故隐患和提高汽车、摩托车等机动车辆尾灯电路的使用寿命，本文设计了一种利用AT89S52单片机对汽车尾灯工作状态进行控制的控制器系统。首先介绍了系统的总体设计方案；其次结合实际应用给出了界面模式与主控芯片单片机的外围电路；为了实现系统的控制功能，采用C语言编程，文中详细介绍了软件设计流程图及实现方法；最后，将软件系统与硬件电路结合调试，实现了左转、右转、刹车及夜间行车四种常用的汽车尾灯状态。

The design of the controller on automobile taillight based on AT89S52

In order to decrease the traffic accident and prolong the life of the automobile and motorcycle Taillight circuits. A Controller of the automobile Taillight control system based on AT89S52 was designed in this paper. At first, the whole design scheme of the system was introduced; and then the interface module combining with practice application and master control single-chip periphery circuit was given; In order to realize the system control function ,the software system was programmed by using C language, the method of the software design and program flow chart were explained in detail ; in the end, the software was combined with the hardware to debug, it has realized the four taillight stats , for example： left-handed rotation, right-handed rotation, brake and running in the evening. The system with simple structure, high reliability, convenient operation and low cost can widely used on automobile and motorcycle and so on. So it has wide application value.
