摘　　要：介绍了一种基于Freescale公司的16位HCS12单片机的一种智能车控制系统,它采用黑白CMOS摄像头作为路径识别装置,通过图像识别提取路径信息。利用单片机产生PWM波,控制小车速度和转向,利用自制的速度传感器来获取小车当前速度,实现速度的闭环控制,增加小车的稳定性,较之常规的光电传感器识别路径方案,利用摄像头传感器可以获取更多的路径信息。测试结果表明,智能车能按任意给定的黑色引导线更能以较快的速度平稳地运行。An intelligent vehicle system based on Fresscale 16-bit single-chip is presented.The system recognizes the path through a CMOS camera,and draws its route information through image recognition.The micro controller unit provides pulse width modulation signals,which controls the speed and direction of the smartcar.The current speed of the car can be got through the speed sensor made by ourselves.This constitutes closed-cycle control system of speed,which can increase the stability of the intelligent car.Compared with the normal route recognition scheme of photoelectric cell sensor,this scheme can obtain more path information.The result of the detection indicates that the smartcar can run smoothly along the black-guide-line given arbitrarily with the more rapid speed.
