Study on Dynamic Torque PID Control for Automobile Diaphragm Spring Clutch Based on Kalman Filter

摘要

This paper built a power transmission model based on Parallel Hybrid Electric Vehicle (PHEV). Based on this model, the Kalman filtering algorithm which was used to estimate the clutch transmitting torque was derived by the state vector which consist of the engine rotation torque and speed. The PID controller which was built based on the Kalman filtering was used to control the deviation between estimated torque and target torque. And the control errors are analyzed by comparing the controlled values and simulated values of the clutch torque at vehicle starting process by engine-driven. The conclusion show that the PID controller has the sufficient accuracy and response speed. Therefore, the PID controller of clutch transmitting torque are feasible.
