Research on stable starting of autonomous vehicles based on PID control

At present, autonomous vehicle is becoming a popular means of transportation, and can gradually become the public choice of transportation. However, autonomous vehicles still face numerous technical challenges. Due to the influence of different forces during the driving process of a car, there are different situations during the starting stage of the car. When approaching the target speed, there may be shaking or difficulty in reaching the target value. Therefore, the PID controller method is adopted to regulate it. This paper focuses on the research of the starting stage of an autonomous vehicle and uses Simulink and MATLAB for analysis. PID controller is used to adjust the parameters of its starting stage. This paper first analyzes the force on the moving vehicle and lists the function formula. Then, this paper puts forward a method of PID controller based on Simulink to adjust the starting parameters of autonomous vehicles. The simulation experiment shows the advantages of the PID controller system, for example, the accuracy can be higher and the response speed can be faster. This study is of great significance for the starting stage of autonomous vehicles.
