考虑加速扭矩补偿的双电机转矩优化分配控制策略研究
Study on optimal torque distribution control strategy for dual motor considering acceleration torque compensation
摘要
Abstract
To improve the overall efficiency and driving performance of the dual-motor powertrain,this paper proposes a torque optimization strategy for the dual-motor drive system of electric vehicles.First,a vehicle powertrain model and simulation platform are built after an analysis of the system architecture.Considering the torque optimization objectives,driving intent,and vehicle state information,a torque optimization strategy is developed to enhance the vehicle's fuel economy and dynamic performance.Finally,simulation tests are conducted to assess its performances.Simulation results show the optimization strategy cuts the acceleration time from 0 km/h to 100 km/h by approximately 5.6%.Under the Federal Test Procedure(FTP75),the efficiency of the front and rear motors reaches 75.58%and 76.86%respectively,up by about 1.59%compared to the equal distribution strategy.Moreover,the optimization strategy exhibits less fluctuations in the battery State of Charge(SOC),reduces energy consumption by about 7.48%,and lowers the energy consumption for a distance of 100 km by approximately 7.69%.This research may provide some insights into efficient energy management and torque distribution control of dual-motor electric vehicles.关键词
