摘　　要：设计并实现了一种基于HCS12单片机的智能寻迹模型车系统。采用飞思卡尔公司HCS12系列16位单片机MC9SDG128作为核心控制单元,使用CCD摄像头采集路面信息。通过对检测图像的分析和计算,自动控制舵机转向,并对直流驱动电机进行PID调速控制,从而实现智能车快速稳定的寻黑线行驶。An intelligent-searching track car model based on HCS12 single-chip microcomputer is designed and implemented. The intelligent car system, with freescale HCS series 16 bit single-chip MC9SDG128 as its control micro-processor, uses CCD camerato obtain lane image information, then energizes the servor to steer according to the analysis of image and adopts PID control strategy to have a control on speed of the system as well. This intelligent car can track the black-guide-line automatically and move forward following the line quickly and smoothly.
