A New Dual Axle Drive Optimization Control Strategy for Electric Vehicles Using Vehicle-to-Infrastructure Communications

In this article, we proposed an optimal torque distribution strategy for pure electric vehicles based on Vehicle-to-Infrastructure (V2I) communication. V2I communication is used to obtain road surface adhesion coefficient, road roughness, and other information. Different speed and torque requirements for different road surface are analyzed. Then, according to motor map characteristics, a dual motor torque optimization distribution control strategy is proposed and a dual motor optimal torque distribution control method for adaptive road surface is established. Finally, the hardware-in-the-loop test system is used to verify the control strategy. New European Driving Cycle is used to simulate the control strategy. The off-line simulation results show that under adaptive road surfaces, the energy optimization rate is improved. To a certain extent, this article can provide a value reference to optimal power distribution strategy for modern smart pure electric vehicles.
