This paper introduces a control system of intelligent tracking the car which uses the design of TMS320F28335 and the color sensor TSC3200. Given the overall design scheme of the car,and this overall scheme including hardware and software aspects. Introduced the car how to identify white path in different color plane and concrete analysis different postures of the car in the process of tracking.The use of 5color sensor to collect road information, the use of DSP as the master chip, according to road information, adjust the steering angle, control the car’s travel and turn so that the car can accurately along the established route automatically. The test results show that the hard system of the intelligent car is simple and reasonable. The design thought of software is efficient and feasible. The intelligent car successful achieved the goal of tracking in different color plane.
