AbstractWith the development of science and technology, the automobile industry has also been rapid development, the automobile research attracts more and more attention from the car. From twentieth Century 70 in the United States and Europe and other developed countries began to study, the driverless cars, China began to develop driverless cars from the 80's of last century, although compared with foreign countries there are still some distance, but it has achieved initial results. Automatic parking system for many are not familiar with the reverse parking novice provides a convenient, currently very few high-end car can achieve unmanned automatic parking. Most car car parking in the process of running speed still need to control the driver. Therefore, even if there is a vehicle automatic parking assist system, car parking in the process, the car after the car there is a blind spot, the line of sight is blocked, and prone to traffic accidents. With the future development of science and technology, I believe that car automatic parking system must sink automatic time design of intelligent control system of the single chip STC89C52 car parking. For a black and white line and library to detect ground is composed of two TCRT5000 light tube uses infrared and single-chip STC89C52 control chip, and control simulation of the car forward and stop the car, to achieve the function of automatic parking. In addition the use of small motor drive chip L298N as DC motor driver chip, using LCD1602A realize the car to stop the running paper introduces the development of intelligent vehicles, the design idea of the subject, circuit and circuit principle of each module, the design process of the project summary and : single chip; infrared light tube driver chip;
