。 the total design schemeBy the system structure has the smart car control system of the process:Start AutoCAD drawing, or choose a closed curve as the car path, pick up the car starting $path graphTo choose the path of the graphics processing, make the car turning of edges on the minimum turning radius in circular arc transitionGenerate a new path graphics, simulation of car movement process。Design of stepping motor control system。Car movement model is established to calculate the data required for car driving。 While the smart car can be done by puter programming for the car stop, driving direction and speed control, without human intervention. Operator the smart car can be changed through a puter program or driving some of the data to change its type. This can be controlled through programming, change the way of car driving feature is the biggest characteristic of the smart car. Smart car control system of the research purpose is to make the car drive has higher autonomy. If any given car a path, through the system, the car can get system of path after image processing of data moving and Angle (a), and can travel scheduled path, according to the displacement and Angle information control system structure analysisAccording to the above design idea, the structure of the intelligent car control system can be divided into two layers The planning layerPC control system, the planning layer provides global information was driving the car, including path processing module and munication module. To solve the basic problem with itUse what tools to deal with the car path graph。s control unit, sensor eightway from outside, in the front of the car, as a black belt in the process of the car into the garage detecting element, at the rear end of the car when connected to eightchannel infrared sensors as the car pulled out of the garage of a black belt in detecting element, the LJ18A38 Z/BX inductive proximity switch as garage iron detecting element, the microcontroller after receiving sensor detects the signal through the corresponding procedures to control the car forward, backward, turn, so that the car39。 (4) electric cars can39。 (2) electric vehicles can store and display the number of detected metal and sheet metal to the starting line in the distance。s moving state. In addition, also expanded the LCD on the car as the humanputer interaction interface, in order to understand the car a realtime monitoring of the realtime data of sensor state machine car, due to the design of intelligent automatic tracking the car, the whole process of task without any manual intervention, so no keyboard and remote control and manual operation of the equipment. With multiple sensors for realtime monitoring and algorithm closely to ensure that the car of plete the task smoothly.Key words: 80 c51, c/c + +, assembly language programming, electronic smart car photoelectric detectorThe introductionIntelligent vehicle is a use of puter, sensor, information, munication, navigation, artificial intelligence and automatic control technology to realize the environment awareness, planning decision and automatic drive of high and new technology. It in aspects such as military, civil and scientific research has received application, to solve the traffic safety provides a new wayWith the rapid development of automobile industry, the research about the car is being more and more attention by people. Contest of national petition and the province of electronic intelligent car almost every time this aspect of the topic, the national various universities are also attaches great importance to research on the topic, many countries have put the electronic design petition as a strategic means of innovative education. Electronic design involving multiple disciplines, machinery and electronics, sensor technology, automatic control technology, artificial intelligent control, puter and munication technology, etc., is a hightech in the field of man
