Abstract :
This paper introduces the design of smart cars based on 16-bit microcontroller MC9S12XS128, which is provided by Freescale Semiconductor Company. The controller is also combined with the steering gear to make up path identification. Its speed control system uses a CCD camera to track the black line through edge detection. In addition, it uses MOSFET to set up H bridges driving circuit. Omron rotary encoder is used for speed feedback. Finally, it is proved that this smart car system can run on the track line steadily.
