ABSTRACT:Intelligent car be automatic operation in the pre-set prospects mode. It is designed by an organic whole of machinery, electronics, detection technology and intelligent control. Intelligent car can be used in the industrial control, it is an important content of the field of Robot research. The toy car is use for the body of Intelligent car in the design. The hardware is made up of the devices of STC89C52RC microcontroller which is the main control chip, dc-motor, photoelectric sensors, LED digital , etc. And it can make the car realize the faction of advances, turn, accelerate, slowing down,etc. It also can accurately finish two cars a starting at the same time, and two cars can run in the same direction in the running lane, realize two car overtaking alternately in overtaking area. The 1602 displays the driving mode of intelligent car. The design shows that this design is simple in structure, reflects intelligent operation in a certain extent and has good robustness.

Key words: Intelligent car; STC89C52RC microcontroller; Infrared sensor; Overtaking alternately

　　　智能車輛是集環(huán)境感知、規(guī)劃決策、多等級(jí)輔助駕駛等功能于一體的綜合系統(tǒng)，是智能交通系統(tǒng)的一個(gè)重要組成部分，其設(shè)計(jì)主要集機(jī)械、電子、檢測(cè)技術(shù)與智能控制于一體，是機(jī)器人研究領(lǐng)域的一項(xiàng)重要內(nèi)容，在軍事、民用、太空開發(fā)等領(lǐng)域有著廣泛的應(yīng)用前景，且其智能技術(shù)廣泛運(yùn)用于各種領(lǐng)域。本選題以設(shè)計(jì)智能小車綜合考察參賽選手對(duì)制造工藝流程管理及自動(dòng)配給、裝配技術(shù)的理解，并著重考察運(yùn)動(dòng)控制方面的能力，提高參賽選手的動(dòng)手能力和分析能力。
