1、课程设计报告设计题目：汽车尾灯控制电路的设计与实现班级：计算机学号：姓名：指导教师：设计时间：24摘要进行本次课程设计主要有两个目的，一是对数字逻辑这门课程的理论知识进行一次系统的梳理；二是锻炼自己将理论应用于实践的能力。针对以上目的，就要求做到，通过分析实际的需求提炼出相应的理论模型，进而再进行电路的设计，在之后的实际电路实现的过程中，还可以根据实际的需要对电路做出一些改进。本课题设计一个汽车尾灯的控制电路。汽车尾部左右两侧各有3个指示灯（用发光二极管模拟）。使用555定时器发出秒脉冲，74LS16

2、1计数器和74LS138以及其他逻辑门实现控制个驱动功能，实现基本要求和扩展，即汽车正常行驶时指示灯不亮；右转弯时右侧3个指示灯按右循环顺序点亮，左侧指示灯全灭；左转弯时左侧3个指示灯按左循环顺序点亮，右侧指示灯全灭；汽车临时刹车和倒车时指示灯闪烁；右转弯刹车时右侧灯顺序循环点亮，左侧灯全亮；左转弯刹车时左侧灯顺序循环点亮，右侧灯全亮以及用数码管显示各个状态等。关键词：计数器，译码器，555定时器，逻辑门等24目录摘要··········································

8、会经济的发展，汽车已经逐步被广泛应用于人们的生产和生活。而对于汽车行驶安全的要求就显得尤为重要，通过科技的力量来改进汽车的性能已经成为主要的方向。立足于《电子技术》这门课程的知识体系，力求通过本学科的一些知识对汽车的尾灯显示电路进行模拟和做出一些分析改进。希望通过这次设计实践，达到两个目的，锻炼自己的动手实践能力，以及用已学的知识对汽车尾灯控制电路进行详尽的分析与模拟。对于汽车尾灯控制电路这项课设，主要有三方面的要求：一是脉冲频率的要求；二是汽车尾灯显示
