In this study, a motor control algorithm for an electric vehicle(EV) with dual clutch transmission(DCT) type 2-speed transmission system was proposed. To evaluate the performance of the proposed motor control algorithm, dynamic model of the DCT type 2-speed transmission system for the EV was constructed and a MATLAB/Simulink based shift performance simulator was developed, which is consisted of a motor, DCT, actuator and vehicle model. Using the simulator, it was found that the change of the acceleration and shift time were reduced by the proposed control algorithm, which provides the improved shift quality.

In this study, a control algorithm of the dual mode power split type hybrid electric vehicle was proposed to reduce the torque variation of the drive shaft during the mode change. To analyze the characteristics of the dual mode power split transmission during mode change, dynamic models for the planetary gear, engine, motor-generator, battery and vehicle were established, and a performance simulator for the dual mode power split transmission hybrid electric vehicle was developed. The control algorithm consists of 1) the engine speed control by the generator torque, 2) the pressure control of the clutch and brake and 3) motor torque compensation. The magnitude of the motor compensation torque was determined from the inertial torque, which was calculated by the inertia of generator and motor and engine speed change. From the simulation results it was found that the torque variation can be effectively reduced by the proposed control algorithm.

In this paper, a dual clutch transmission(DCT) shift performance simulator were developed to evaluate the shift quality using MATLAB/Simulink and SimDriveline. Dynamic models of the DCT were obtained including synchronizer, gear fork actuator system, and clutch Based on the dynamic models, a DCT shift performance simulator was developed. Test and simulation results were compared to verify the DCT shift performance simulator. It was found that the test and simulation results were good agreement, and it is expected that developed simulator can be used to improve the shift quality of the DCT.
