Research on Three-Parameter Shift Control Strategy of Battery Electric Vehicle
In order to improve the power and economy characteristic of pure electric vehicles,a three parameter shifting strategy for a two-speed automated manual transmission(AMT)has been developed to improve the operating conditions of the electric motor and enhance the efficiency of the driving electric motor.A vehicle model was established based on Matlab-Simulink.The battery SOC was supple-mentary to respectively formulate the dynamic-oriented and economic-oriented shifting strategies.The simulation results indicate that the vehicle has a better power and economy characteristic whilst adopting the three-parameter shifting strategy.The acceleration time and energy consumption can be improved remarkably.The vehicle's economic performance with the three-parameter shifting strategy is promoted compared with the two-parameter shifting strategy,based on the NEDC and UDDS.
