Abstract:

：Taking the hybrid electric vehicle equipped with dual clutch transmission(DCT) as the object and considering the characteristics of fast responding and high accuracy of integrated starter and generator(ISG) motor speed and torque, the robust control issue of torque coordination between twin clutches and power sources when ISG intervene with the gear-shifting process are investigated. The different dynamics models in the different phases of whole shifting process are established; Then, the power sources' synthesizing torque is optimally determined under the consideration of the responding characteristic of clutch actuators in the torque phase and the model uncertainty & external disturbance(measurement noise and engine torque’s lag) in the inertia phase; Afterwards, in the torque transition phase, the engine torque is switched into the level of driver demand and ISG torque is slowly come down. Finally, the torques of the power sources are distributed based on the optimization of system efficiency. The simulation results on the Simulink software platform illustrate that the proposed control strategies possess the capabilities of strong anti-uncertainty and anti-disturbance. And the following bench test results further show that it can also effectively address the coordinating control problems between the twin clutches and power sources, ensure that the vehicle has good quality in shift.
