Research in Torque Distribution of Dual Motor Electric Vehicle Based on PSO

This paper proposed real-time optimization algorithm in order to solve the problem which the dynamic nonlinear torque distribution of rear dual-hub-motor-driven vehicle. Based on the research of a company’s rear-wheel drive double-wheel hub motor, build the control model by MATLAB, the vehicle model set up by CarSim, and Co-simulation test the performance of algorithm. Then hardware-in-loop test based on the VCU. The result shown that the algorithm could distributed torque according to the actual working conditions, reduced the slip ratio, improved the driving performance of vehicle.
