Shift Schedule Optimization for AMT of EVs based on Motor Efficiency
2017
Based on the analysis of the characteristics of vehicle and the motor, a new method for calculating the best efficiency shift schedule was proposed for electric vehicles (EVs) with 3-speed AMT. The proposed shift schedule was tested and compared with the best dynamic performance shift schedule through acceleration and ECE+EUDU driving cycle simulation using MATLAB/Simulink software. The simulation results demonstrate that the best efficiency shift schedule improves the economic performance by 6.91%, but reduces the dynamic performance by 7.43%, which is more suitable for economic driving style.
