With the development of science and technology, the automobile industry has also developed rapidly, and automobile research has attracted more and more attention. Developed countries such as the United States and Europe began to study driverless cars in the 1970s, and China began to develop driverless cars in the 1980s. Although there is still a certain distance compared with foreign countries, it has achieved initial results. Automatic parking system provides convenience for many novices who are not familiar with reversing parking. At present, few high-end cars can realize unmanned automatic parking. The parking speed of most cars still needs the driver's control during driving. Therefore, even if there is an automatic parking assistance system, there is a blind spot behind the car during the parking process, and the line of sight is blocked, which is prone to traffic accidents. With the development of science and technology in the future, I believe that the automatic parking system will soon sink the automatic time.

Design of intelligent control system for parking lot based on single chip microcomputer STC89C52. The black-and-white line and library used to detect the ground are composed of two TCRT5000 light tubes. The infrared and single-chip computer STC89C52 are used to control the simulation car to move forward and park, thus realizing the function of automatic parking. In addition, L298N, a small motor driver chip, is used as the DC motor driver chip, and LCD 1602A is used to realize the stopping time of the car.

This paper introduces the development of intelligent vehicle, the design idea of the subject, the circuit principle of each module, the summary and prospect of the project design process.
