Study on Torque Distribution of Master and Auxiliary Motor Coupled Driving System

electric vehicle,,torque distribution,energy conversation potential

This paper focused on the torque distribution of master and auxiliary motor coupled driving system for the pure electric vehicle. With the minimum consumption of power as the target, the equivalent PESCM method was employed. The torque split maps of master and auxiliary motor were obtained .The simulation model was built in MATLAB/Simulink and the simulation was carried out .Both the results of simulation and tests indicate the strategy can realize the rational torque distribution, more than double motor independent drive and equal torque drive to expand the efficient working range, improve the energy conversation potential.
