【正文】 ion infrared sensors to detect the signal sent to the microcontroller, a corresponding control signal according to the program MCU control cars automatically avoid obstacles, to carry on the back, forward, turn left, turn rightSubject partsIntelligent vehicle is a concentration of environment awareness, planning decision, multiscale auxiliary driving, and other functions in an integrated system, is an important part of intelligent transportation system. In military, civilian, space exploration and other fields has a broad application prospect. The design of smart car control system are studied, based on path planning is a process of the intelligent car control system theory is put forwardThe progress of science and technology of intelligent led products, but also accelerated the pace of development, MCU application scope of its application is increasingly wide, has gone far beyond the field of puter science. Small to toys, credit CARDS, big to the space shuttle, robots, from data acquisition, remote control and fuzzy control, intelligent systems with the human daily life, everywhere is dependent on the single chip microputer, this design is a typical application of single chip microputer. This design by implementing the driverless car, on the tests, by the reaction of the single chip microputer to control the car, make its bee intelligent, automatic forward, turn and stop function, after continuing the perfection of this system also can be applied to road testing, security patrol, can meet the needs of society.In design, the use of the sensors to detect road surface condition, sensor central sea are faint and adopts a paring amplifier amplification, and the signal input to the controller, the controlled end using stepper motor, because of the step motor is controlled electrical pulse, as long as the output from the controller to satisfy stepper motor merits of fixed control word. In operation of stepping motor and a driving circuit, it also to join a drive circuit in the circuit, each function module is different to the requirement of power supply current, the power supply part set up conversion circuit, so as to meet the needs of the various parts. After parison choice element, design the circuit principle diagram and the circuit board, and do the debugging of hardware, system software and hardware is often the bination of organic whole. Software, on the use of the 51 singlechip timer interrupt to control pavement test interval and the car movement and speed. Due to take that road is simple, it is using more traditional assembly language for programming. For the correctness of the program design, using a monly used keil c51 simulation software simulation validation, the last is integrated debugging of software and hardware, and prove the correctness and feasibility of the design scheme. electronic intelligent car design requirements(1) electric vehicles can be able to according to the course to run all the way。 執(zhí)行模塊：執(zhí)行模塊是由液晶顯示、電機(jī)驅(qū)動(dòng)及電機(jī)、蜂鳴器三部分組成。它要解決的基本問(wèn)題 有：(1) 接收、處理上位機(jī)發(fā)送的數(shù)據(jù)信息；(2) 設(shè)計(jì)步進(jìn)電機(jī)的控制系統(tǒng)；(3) 采集小車的位移和轉(zhuǎn)角信息，定位小車姿態(tài)，分析系統(tǒng)控制誤差； 總設(shè)計(jì)方案由系統(tǒng)結(jié)構(gòu)得到智能小車控制系統(tǒng)的命令流程：（1） 啟動(dòng)AutoCAD，繪制或選擇一條封閉曲線為小車路徑，拾取小車的起始路徑圖元（2） 對(duì)選取的路徑圖形進(jìn)行處理，使小車轉(zhuǎn)彎處存在的棱角在最小轉(zhuǎn)彎半徑范圍外以圓弧方式過(guò)渡（3） 生成新的路徑圖形，模擬小車的運(yùn)動(dòng)過(guò)程；（4） 計(jì)算出小車行駛所需要的位移和車輪轉(zhuǎn)角，并將此數(shù)據(jù)發(fā)送給下位機(jī)（5） 下位機(jī)接收數(shù)據(jù)后，通過(guò)軟件編程控制小車車輪的轉(zhuǎn)速和轉(zhuǎn)角，使其按照 預(yù)定路徑前進(jìn) 一個(gè)完整的控制系統(tǒng)要求系統(tǒng)的各功能模塊聯(lián)系緊密，根據(jù)上述命令流程和它們之間的關(guān)系，可得系統(tǒng)的總設(shè)計(jì)方案。這種可以通過(guò)編程來(lái)控制、改變小車行駛方式的特性是智能小車的最大特點(diǎn)。它以車輪作為移動(dòng)機(jī)構(gòu)、能夠?qū)崿F(xiàn)自主 行駛，所以我們稱之為智能小車。對(duì)于程序設(shè)計(jì)的正確性，用較常用的keil c51仿真軟件進(jìn)行仿真驗(yàn)證，最后便是軟硬件的綜合調(diào)試，證明本設(shè)計(jì)方案的正確性和可行性。此外步進(jìn)電機(jī)的運(yùn)作還要一個(gè)驅(qū)動(dòng)電路，故電路中還要加入一個(gè)驅(qū)動(dòng)電路，各個(gè)功能模塊對(duì)電源電流的要求不同，對(duì)電源部分設(shè)置轉(zhuǎn)換電路，從而滿足各個(gè)部分的需要。本次設(shè)計(jì)對(duì)智能小車的控制系統(tǒng)進(jìn)行了研究，設(shè)計(jì)實(shí)現(xiàn)一個(gè)基于路徑規(guī)劃處理的智能小車控制系統(tǒng) 理論的提出 科技的進(jìn)步帶動(dòng)了產(chǎn)品的智能化，單片機(jī)的應(yīng)用更是加快了發(fā)展的步伐，它的應(yīng)用范圍日益廣泛，已經(jīng)遠(yuǎn)遠(yuǎn)的超出了計(jì)算機(jī)科學(xué)領(lǐng)域。電子設(shè)計(jì)技術(shù)，它是一個(gè)國(guó)家高科技實(shí)例的一個(gè)重要標(biāo)準(zhǔn)，可見其研究意義很大 本次設(shè)計(jì)雖然只是一個(gè)演示模型，但是具有充分的科學(xué)性和實(shí)用性。 關(guān)鍵字：80c51單片機(jī)，c/c++/匯編語(yǔ)言編程，電子智能小車，光電檢測(cè)器 引言 智能車輛是一個(gè)運(yùn)用計(jì)算機(jī)、傳感、信息、通信、導(dǎo)航、人工智能及自動(dòng)控制等技術(shù)來(lái)實(shí)現(xiàn)環(huán)境感知、規(guī)劃決策和自動(dòng)行駛為一體的高新技術(shù)綜合體。運(yùn)用反射式紅
