摘　　要：根据湿式离合器传动的特点,提出了湿式离合器接合过程中基于滑差率的摩擦片间压力的在线确定方法,并以此作为目标压力对离合器进行控制。仿真结果表明,基于滑差率的CVT离合器模糊自适应PID控制能较好的控制离合器接合过程,使汽车能够平稳快速起步。In accordance with the feature of the wet clutch transmission, an online method for determining the CVT wet clutch in pressure between the friction plates based on the slip rate is proposed, which is taken as the target pressure to control the clutch. The emulation result proves that the fuzzy self- adaptive PID control based on slip ratio for CVT clutch control is able to better control the clutch engaging process, making vehicles a smooth and rapid launch.
