Simulation Research on the Control Performance of CVT Starting-Clutch

摘要：

　　Aiming at the control problem for starting-clutch of CVT vehicle,the control goals have been analyzed for different stages,for the principle that decrease jerk and friction work,the fuzzy control algorithm have been proposed.The complete vehicle model is modeled combining engine model with clutch dynamic model,clutch hydraulic model,resistance torque model and engagement pressures model.According to the complete vehicle model,different starting simulations are gained by changing the throttle opening and change rate.It can be seen from the simulation results,both the jerk and friction work are restricted within a reasonable range after the fuzzy control algorithm is adopted,which brings relatively smooth startup and enough service life for clutch.The engine has small speed variation during the startup process,which reduces fuel consumption and noise effectively.
