摘　　要：本文基于纯电动四驱汽车前后桥的电驱损伤,对前后桥扭矩分配控制方法进行研究。根据前后桥电驱损伤与前后桥电驱的目标损伤进行对比分析,提出了前后桥扭矩分配方案,再进行方案寻优,得到最优的四驱扭矩分配控制方法。本文提出的一种基于电驱损伤的电四驱扭矩控制方法,可以避免因电机损伤过大导致电机损坏,以延长开发周期。In this paper,based on front and rear electric drive damage of EV vehicle,researched the torque distribution control method of front and rear axle.According to compare the damage of electric drive and the target damage,the torque distribution scheme of front and rear axle is proposed,and the optimal control method of four-wheel drive torque distribution is obtained.This paper presents an electric four-wheel drive torque control method based on electric drive damage,which can avoid motor damage due to excessive motor damage and prolong the development cycle.
