摘　　要：针对当前双电机耦合驱动系统工作效率最优区间及工作模式转换之间的难题,研究为保证驱动系统动力性及经济性平衡,对其进行试验台架设计。首先依据纯电动汽车动力需求对其进行双电机驱动系统参数匹配设计,随后依据模糊控制思路设计能量管理策略。同时基于道路工况信息基础对动力参数的匹配分析,并提出高效转矩补偿策略来确保双电机的效率分配。结果表明,双电机动力系统在中高时速下的爬坡能力表现较好,且其在两种工况下的工作点平均效率值均在80%以上,续航里程能力有所增加,表现出较好的动力性和经济性。研究基于模糊控制和试验台架的设计能有效考虑到新能源汽车运行工况需求,满足整车测试系统需求,有利于车用动力系统的开发。To address the challenges of the optimal efficiency range and mode conversion in the current dual motor coupled drive system,a test bench design was conducted to ensure the balance of power and economy in the drive system.Firstly,based on the power requirements of pure electric vehicles,a dual motor drive system parameter matching design is carried out,and then an energy management strategy is designed using fuzzy control ideas.At the same time,based on road condition information,matching analysis of power parameters is carried out,and an efficient torque compensation strategy is proposed to ensure the efficiency distribution of du-al motors.The results show that the dual motor power system performs well in climbing ability at medium and high speeds,and its av-erage efficiency value at both operating points is above 80%.The range capacity has increased,demonstrating good power and econo-my.The design based on fuzzy control and test bench can effectively consider the operating conditions of new energy vehicles,meet the requirements of the entire vehicle testing system,and facilitate the development of vehicle power systems.
