| Abstract: | This paper demonstrate an intelligent car system based on the micro - controller unit MC68S912DG128. The micro -controller use a CMOS image sensor to obtain line image information ,then adjusts the model car＇s moving position and direction. An inferred sensor measure the car＇s moving speed. We use PID control methods to adjust, the rotate speed of driving electromotor and direction of steering electromotor. So,we complete the closed - loop control to the speed and direction. The result of experiment indicate that the design scheme of system is doable. |
