Abstract

In order to improve the shift quality of electric vehicles equipped with combined clutch transmission, a dynamic model of shifting process is established. The shift jerk and friction work are chosen as a comprehensive control target. Linear quadratic optimal control to optimize the shifting process of planetary transmission is used, in which motor is involved. The simulation results show by the coordinated control of the motor torque and oil pressure the shift jerk and friction work are decreased by 32% and by 48% respectively, compared with combined clutch control only.
