Design of an intelligent-searching track car based on MC9S12DG128 SCM

An intelligent-searching track car system based on MC9S12DG128 MCU is designed.The system uses MC9S12DG128 as its control core and uses CCD sensors to detect the route information,and its acceleration and speed is detected by sensors.The system adopts PID arithmetic to control the DC motor and adopts fuzzy control arithmetic to ener-gize the steering motor.The intelligent car can track the black-guide line automatically and move forward following the line quickly and smoothly.
