Shifting control and simulation of wet dual clutch transmission
摘要
Abstract
The dynamic model of the shift process of wet dual clutch transmission (DCT) is set up. Aiming at the characteristics of wet dual clutch transmission, such as being highly nonlinear and difficult to establish its math model, etc. , a multiple rule weighting factor fuzzy controller is designed. Then the control scheme of shift process is built, which completes the transfer of engine torque through a combination of a manipulation of engine control and clutch pressure. Dynamic simulation model of wet DCT power train is implemented by using Matlab/Simulink software, the control scheme of shift process is simulated based on this dynamic model. The simulation results show that the control scheme can meet the needs of DCT shift process, and the tracking performance of controller is good. Finally, influencing factors of transmission shift control is discussed.关键词
