With the advancement of science and technology, intelligent and mechatronics technologies are becoming more and more popular, and various high-techs are also commonly used in the field of smart cars, making smart cars more and more diversified. The smart car is an integrated body of various high-tech. It integrates many kinds of scientific knowledge such as electronics, machinery, sensors, software, intelligence, etc., and can involve many current cutting-edge technologies and fields. This paper designs a simple smart car system based on single-chip microcomputer control, focusing on the software and hardware composition methods and design methods of the smart car system. The car will be controlled with STC89C52 as the core, using a single-chip microcomputer to control the L298N motor drive module to control the walking of the smart car. Ultrasonic sensors will be used to accurately detect road obstacles to achieve the obstacle avoidance function; infrared sensors will be used to detect road trajectories, and the detected signals will be fed back to the single-chip microcomputer to achieve the tracking function. The single-chip microcomputer will judge and analyze the collected signals, and control the drive motor to make the smart car perform the steering function, so that the smart car avoids obstacles in front and walks along the route to realize the automatic tracking and obstacle avoidance functions of the smart car.

With the progress of science and technology, intelligent and mechatronic technology is becoming more and more popular, a variety of high-tech is also widely used in the field of smart cars, so that smart cars are more and more diversified. Smart car is an integration of various high-tech, it combines electronics, machinery, sensors and software, intelligence and many other kinds of scientific knowledge, can involve many cutting-edge technology and fields. In this paper, a simple intelligent car system based on microcontroller control is designed, which focuses on the software, hardware composition method and design method of intelligent car system. The car will be STC89C52 as the core control, the use of a microcontroller to control the L298N motor drive module, control the intelligent car walking. The road obstacles will be accurately detected by ultrasonic sensors in order to realize the function of obstacle avoidance. Infrared sensors are used to detect road tracks and feed detected signals back to a microcontroller to achieve track-through functions. The single opportunity to judge and analyze the collected signal, the control drive motor will allow the intelligent car to turn function, so that the intelligent car avoids the obstacles ahead, walks along the route, realizes the automatic track of the intelligent car and the function of avoiding obstacles.
