This paper proposes a design and implementation of intelligent model car based on Renesas R8C/38A Single Chip Microcomputer(SCM). The model car uses infrared sensors to obtain lane image information,and employs the Renesas R8C/38A as its control micro-processor. Through the open-loop proportional control on servo to change the direction and the closed-loop PID control on motors to control the speed,the model car can realize to track the lane automatically. Practice proves that the scheme is reasonable and effective to make the model car pass the crank, lane change and other special lane smoothly,and it has the characteristics of optimal tracing line,fast adjustable speed,strong anti-interference performance,little steady-state error,also has good dynamic and steering performance.
