| With the development of science and technology,embedded system are usedmore and more extensive in the field of control,and the Intelligent Vehicle which isbased on embedded system plays an more and more important role in IntelligentTraffic System.This article is based on the Traffic Research Laboratory constructionof South China University of Technology in Guangzhou modern industrial technologyresearch institute, In this paper, the intelligent automobile kinetic control system isdesigned, the hardware platform of intelligent automobile control system is based onCortex-M3as the core, through the sensors to achieve the multiple functions of theautomobile.In this paper, according to the characteristics of motors, the intelligent vehiclekinematics model is built. The Fuzzy Controller is designed according to the wheeldeviation and deviation change rate, and the PID Controller is designed according tointelligent vehicle speed deviationl and then, Both of the Fuzzy Controller and PIDController are simulated in MATLAB circumstances, and the results explains thesuperiority of Fuzzy Controller and PID Controller.At the sametime, The Wireless Application Protocol is designed between TrafficSignal Controller and the Intelligent Vehicle, making that the vehicle can recognisethe traffic lights state become true. At last, the uC/OS-II RTOS is transplanted intoCortex-M3, the real-time of Intelligent Vehicle’s control system has been improved.The main content of this paper is the follwing aspects: Firstly, intelligentvehicle’s key technologies and research status at home and abroad are analysised;Secondly, intelligent automobile kinetic control system is designed according toselected Microprocessor and sensors, and then, the kinematics model、 FuzzyControlleer and PID Controller are designed; Moreover, In order to solve the problemof traffic lights recognition, The Wireless Application Protocol is designed; Finally,The uC/OS-II RTOS is transplanted into Cortex-M3. |
