Optimal torque distribution for energy consumption in distributed 4WD electric vehicles

Abstract

In order to reduce the energy consumption problem of distributed 4WD electric vehicles, a torque distribution strategy based on energy consumption optimization is proposed. Firstly, the dynamics of the distributed 4WD electric vehicle is analyzed, and the forward simulation model of the distributed 4WD electric vehicle is established in combination with the European cyclic conditions; secondly, based on the analysis of the energy consumption characteristics of the distributed 4WD electric vehicle, the mathematical model of the optimal torque distribution is established with the objective of reducing the energy consumption of the whole vehicle, and the objective function is optimized using the artificial fish swarm algorithm to obtain the torque distribution results when the energy consumption is optimal, and the total loss of the system is simulated in combination with the whole vehicle The simulation analysis of the total loss of the system is carried out in combination with the vehicle model. The simulation results show that the optimal torque allocation scheme obtained by the artificial fish swarm algorithm for distributed 4WD electric vehicles can effectively reduce the energy consumption of the whole vehicle.
