随动转向车灯毕业设计

摘要

随着我国经济水平的提高和汽车工业技术的发展，对汽车安全性要求越来越高。影响安全性的因素较多，有主动因素，也有被动因素，汽车车灯正常工作，能否保证驾驶员能即时给出行车信号和在夜间行车的良好视野范围是一个重要因素。对汽车前照灯的控控已有成熟控制技术用于汽车，而对信号灯的控制较少]6[。本文根据现有技术的情况，引入模糊控制技术，对汽车的前照灯进行较为全面的分析，同时对汽车的随动转向灯的结构和机械传动进行了设计。本设计着重对以下问题进行了研究与探讨：

1、对汽车车灯控制参量进行了研究分析，确定了合理的参数类型和数量，使系统开发具有可行性和实用性；

2、把模糊控制理论应用于汽车前照灯的控制，并对控制器进行了设计；

3、构建了随动转向灯的结构与传动。

ABSTRACT

With the improvement of the economic level of our country and the development of the industrial technology of the automobile,the demands on the auto safety are higher.There are mant safety factors which are active or passive.It is a important factor that automobile’s lights is normal which can give driving signals in light intime according to the driver and good field of view. The head lights are used to control by maturity control technology,bur single lights control less.The article uses fuzzy control technique to control totally auto head lights and work state ofsingle lights timely.It researches and probes for contents of intelligent control of auto lights,the principle of controlling and realization of the system of software and hardware.This text put great emphasos in to research and study below impaortant problem proceed detailed:

First,researched the analyzed the parameters of auto lights,and make sure type and quantity of control parnmeters,so as to make it feasible and practical for developing system of auto lights control.

Second,used fuzzy control technique theory for auto head lights and designed contriller.

Third,probed realization of measuring technology by self and voice warning for auto signal lights.

At last,structured intelligent control system of auto lights which core is single-chip computer MS-51.

Key words: auto head lights,Directional headlamps,single-chop computer,Mechanical transmission,fuzzy control
