An intelligent car design method is introduced. In the method, Freescale K60 microcontroller unit （MCU） is used as the core process device, CMOS is used to acquire runway path and it is equipped with active blue lighting systems for auxiliary illumination to realize precision navigation. During the car moving, the number of red Zhonghua pencil on both sides of the runway and the car passing in or out of the tunnel can be measured by laser detection modules equipped with the car. And the feedback signals processed by PID algorithm from the electro-optical coder can be used to control the speed of the intelligent car and the tunnel length can be calculated in the tun- nel. Experimental results show that the car has reasonable design, stable circuit, fast speed and stable driving and accurate measurement, which has important significance in the application of intelligent car measurement.
