摘要：AbstractFor Dual Clutch Transmission (DCT) vehicle, this study provides a launch control method that coordinates the transmission torque of twin clutches. The launching process is divided into 2 stages. For the first stage, the total torque is obtained by using Model Predictive Control (MPC) method, and total torque is distributed to two clutches based on principle of equal slipping work. For the second stage, a torque distribution rule is given to allow launching clutch engaged and separating clutch disengaged. Then, stability of MPC controller is discussed. Compared with single clutch launch PID controller, the simulation results show that the proposed MPC launch controller could greatly shorten the time of launching process, decrease slipping work, avoid possible power coupling and power cycling.
