Research and Design of Infrared Automatic Track-following and Obstacle Avoidance Intelligent Vehicle at Intersection

With the development of urban modernization, the level of motorization has been continuously improved, which has caused a large number of traffic accidents while the travel is convenient and fast. Therefore, it is particularly important to design a smart car that can follow and avoid obstacles and reduce the number of accidents at intersections. At present, most intelligent cars on the market are not designed with any auxiliary functions, low intelligence, high production cost and low stability coefficient, and the experimental results are quite different from the expected assumptions, and cannot meet the requirements of stable, accurate and fast control in different environments. With STC8A8K32S4A12 as the core, this project builds a buck module to supply power to the MCU. The main modules include infrared photoelectric tracking module, metal ultrasonic detection module, motor drive, Bluetooth remote control, etc., which can realize car tracking, ultrasonic obstacle avoidance display, Bluetooth remote control and other functions. It has reference significance for promoting intelligent transportation and safe transportation.
