Research on Shift Coordination Control and Simulation of Two-speed AMT Pure Electric Vehicles
Compared with traditional internal combustion engine vehicles,pure electric vehicles have sig-nificant advantages in environmental protection,and vigorously developing electric vehicles has become the mainstream trend of automotive industry development.This paper takes the pure electric vehicle automatic transmission Automated Mechanical Transmission as the object,carries on the research to its parameter shift schedule.According To the motor characteristics and vehicle driving dynamics equation,the simulation model is established by MATLAB/Simulink.The simulation software MATLAB/S-function is used to establish the simulation model of the shift control strategy and the simulation analysis is carried out to verify the effectiveness of the program.The simulation results show that the established simulation model and the designed shift sched-ule are reasonable and feasible.
