 摘要
 隨著計(jì)算機(jī)技術(shù)和人工智能技術(shù)的飛速發(fā)展，使智能小車(chē)在功能和技術(shù)層次方面都有了很大提高，可以按照預(yù)先設(shè)定的模式在一個(gè)環(huán)境里自動(dòng)的運(yùn)作，不需要人為的管理，可應(yīng)用于科學(xué)勘探等的用途，在工業(yè)生產(chǎn)中常用來(lái)完成運(yùn)輸和上下料等任務(wù)，同時(shí)也可被廣泛用于旅游、醫(yī)療等不同行業(yè)。
 智能小車(chē)技術(shù)是近年來(lái)的研究熱點(diǎn)，自主行駛是其最基本的功能。本次設(shè)計(jì)的智能小車(chē)根據(jù)自主行駛要求分成四大模塊，電機(jī)驅(qū)動(dòng)模塊、光碼盤(pán)測(cè)速模塊、液晶顯示模塊，遙控電路模塊。論文詳細(xì)介紹了每個(gè)模塊的基本功能和設(shè)計(jì)方法，并完成各模塊硬件的制作和調(diào)試。最后配以所設(shè)計(jì)的程序?qū)崿F(xiàn)了系統(tǒng)的指標(biāo)要求。本設(shè)計(jì)結(jié)構(gòu)簡(jiǎn)單，實(shí)現(xiàn)容易，所設(shè)計(jì)智能小車(chē)具有高度的智能化、人性化等特點(diǎn)，具有較好的應(yīng)用價(jià)值。

 Abstract
 With the rapid development of computer technology and artificial intelligence, the smart car has been greatly improved in the functional and technical level. Without human management, it can operate automatically under the pre-determined model. As a result, the smart car can be used in scientific prospecting and industrial production for transporting, loading and blanking. Furth -ermore, it can also be widely used in tourism, medical care, and other industries.
 The technology of smart car is a research hotspot in recent years and self-driving is its most basic function. In this study, the smart car is divided into four modules according to the requirem -ent of self-driving---motor drive module, optical encoder velocimetry module, liquid crystal dis -play module and remote control circuit module. This paper introduces in detail the basic functio -ns and design methods of each module, and completed the production and debugging of hardw -are in each module. Finally, with procedures designed, it achieves the target requirements of the system. In this design, the structure is simple, easy to achieve, and the smart car is designed with a high degree of intelligent and user-friendly features and so on, which gives the smart car better ap -plication value.
