| 摘 要： | 针对湿式双离合器自动变速器（dual clutch transmission，DCT）在换挡过程中与离合器压力控制相关的问题，建立了湿式DCT离合器压力控制系统模型；根据双离合器的工作状态，提出了DCT换挡过程中离合器压力控制策略，并设计了离合器压力模糊控制算法；利用MATLAB／Simulink搭建了控制系统仿真模型，并通过升、降挡过程的仿真，得到了冲击度和滑摩功的仿真曲线，验证了液压系统模型的正确性和控制算法的有效性。

| Abstract: | According to the related problems of controlling pressure of a clutch during the shift process of wet DCT , the model of the hydraulic control system for wet DCT is designed. In establishing the control strategy of cluth pressure of DCT based on the state of clutches, the fuzzy control algorithm of the oil pressure of the clutch is designed. The simulation model of the control system is built using MATLAB/Simulink and the simulation curve of shift jerk and friction work is set up, and proved correctness of the models of hydraulic control system, and the validity of the control algorithm through the simulation of the upshift and downshift process. |
