基于单片机的智能车导航系统设计

摘要

智能车导航系统能自动寻迹，自主识别赛道且行驶准确稳定快速．在CodeWarrior开发环境中，采用C语言为设计软件，以Freescale公司的MC9S12XS128B单片机为控制芯片，外围控制电路及芯片驱动电路采用Protel99SE为设计工具，由CMOS数字摄像头实现路径识别．仿真测试表明：本系统不仅能完成智能车对路径的识别功能，而且还具有很好的抗干扰能力，舵机转动快，电机控制稳定，具有良好的动态性能．%The auto navigation system of intelligent car has the functions of automatic tracing, automatic recognition of track, and stable and rapid driving. The software of this system is designed based on CodeWarrior with using C language tool as development environment. The system core uses the single chip microcomputer MC9S12XS128B from Freescale company. And its peripheral Circuit and chip driver' s circuits are designed by Protel 99SE. It uses CMOS digital camera to realize path recognition through the cars closed loop control. Simulation test shows that this system can content the path recognition and has a good anti-disturbance capacity. At the same time its steering engine can adjust to fast response time, motor control is stable and the dynamic performance is good.
