Shift control of a 2-speed dual clutch transmission for electric vehicle

东楚霸王

This paper suggested a shift control algorithm for improving the shift quality(SQ) by modeling a dual clutch transmission(DCT)-type 2-speed transmission system for an electric vehicle(EV). In 2-speed transmission system, the driving comfort decreased when the driveshaft torque of the vehicle fluctuated by shifting gear, unlike with the existing single-gear ratio EV. To improve this, a shift control algorithm was proposed that controlled two units of shift actuators and a unit of a driving motor for the subject DCT. To evaluate the proposed shift control algorithm, a shift performance simulator based on MATLAB/Simulink that consisted of a motor, DCT, actuator, and vehicle model was developed by modeling a DCTtype EV with 2-speed transmission system. The SQ improvement was verified by reducing the overshoot torque of the driveshaft during inertia phase.
