摘 要：In this paper we propose a intelligent vehicle system design with MK60NS12VMD100 as the micro-controller unit and CMOS image sensor to obtain image information of the track.Our proposed comparator circuit instead of an A/D conversion to obtain the binary image enables us to achieve a bigger field of view and a higher processing speed.A unique algorithm to extract track information and to successfully extract the black guide line is devised.We also design a PID closed-loop control to adjust the rotate speed of driving electromotor and direction of steering electromotor.The results indicate that our design proposal is feasible.The intelligent vehicle could successfully achieve a high speed,while maintaining an excellent stability.
