In this paper we propose a intelligent vehicle system design with MK60N512VMD100 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.
