摘要
针对干式双离合器自动变速器系统,研究了电机驱动的干式双离合器执行机构,分析了膜片弹簧载荷变形特性和离合器扭矩动态传递特性,采用模糊控制和PI(proportion integration)控制的双闭环控制方法,建立了干式双离合器控制系统数学模型,进行了DCT(dual clutch transmission)换挡过程仿真。结果表明电机驱动的干式双离合器及其控制系统,能够满足DCT换挡过程的要求,实现了DCT系统高性能的特性。
Aiming at the dry Dual Clutch Transmission (DCT) system, the motor-driven dry dual clutch actuator is studied; the characteristic of distortion-load for diaphragm spring and the dynamic transient process of the clutch are analyzed. The mathematical model is established for the system using fuzzy control and PI (Proportion Integration) control, and the simulation is carried out for the DCT shifting process. Simulation results indicate that the motor-driven dry dual clutch system can meet the need of the shifting process control requirements and guarantee the high performance of DCT system.
