According to the advantage of the two speeds transmission in pure electric vehicle, the 2AMT basic structure and shifting mechanism is designed, the principle of shifting, the shift in the shift process and possible problems are described in detail and shift process of electric vehicles without clucch is analyzed. Based on influence of the impact of shifting on the shift quality in the process of shifting, the torque control is proposed. The control strategy model is established by Matlab/Simulink and modeling and simulation are carried out on a certain vehicle on Cruise platform. Finally testing for validation is performed. The results show a small degree shift shock and the high shift quality, indicating that the transmission and the designed control scheme can well meet the requirements.
