Abstract
It is difficult to adjust parameters automatically to obtain the optimal control parameters, and the steering performance of the system is often not ideal. In order to solve this problem, this paper designs an automotive electronic control type power steering system based on PID under the Internet of Things environment. A switching step-down circuit is composed of a combined power supply mode, and then the drive circuit is designed, and the output end is flexibly configured through the control pin. In the software design part, the vehicle system dynamics model is established by analyzing the steering resistance torque, and then the proportional relationship between the power assist torque and the motor current is determined. Finally, the PID control algorithm is designed to set the control parameters automatically. Finally, the main program of the control system is set up, and the bus is used as the connecting medium to control the driving torque of the vehicle. The experimental results show that the system has good steering performance, and the test results of steering Angle, yaw velocity, lateral acceleration and offset path are better than those of the existing system, which is beneficial to the safe driving of the vehicle.
