In accordance with the feature of the wet clutch transmission

an online method for determining the CVT wet clutch in pressure between the frict ion 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-adapt ive PID control based on slip rat io for CVT clutch control is able to better control the clutch engaging process

making vehicles a smooth and rapid launch.
