摘要/Abstract

摘要： 针对分布式电动汽车四轮驱动系统的冗余结构，驱动轮之间动力控制易出现干涉耦合效应，为此建立电动汽车四驱动轮动力优化控制系统。联合 MATLAB 和 CarSim 建立了整车动力学模型及电机驱动协调优化控制模型，其中包含计算驾驶需求动力及广义稳定横摆力矩的上控制层，以轮胎附着裕量、稳定性及动力性为优化目标的转矩分配控制层，通过与无动力优化控制系统分析对比，验证了优化动力控制系统的正确性及有效性，表明了其控制系统的适应性能更优。

Abstract: In view of the redundant structure of the distributed four-wheel drive system of electric vehicle, the power control between the driving wheels is prone to interference coupling effect, so the power optimization control system of the four-wheel drive of electric vehicle is established. Combined with MATLAB and CarSim, the vehicle dynamics model and motor drive coordination optimization control model are established, including the upper control layer for calculating driving demand force and generalized stable yaw moment. By comparing the torque distribution control layer with the non-dynamic control system, the correctness and effectiveness of the optimized dynamic control system are verified, and the adaptive performance of the control system is better.

Key words: Electric vehicle; Power optimization; Independent drive; Torque distribution
