电机效率最优的双电机汽车驱动扭矩分配控制策略
Torque distribution control strategy for distributed drive electric vehicles based on the best motor efficiency
摘要
Abstract
To improve the efficiency of front and rear axle distributed dual electric vehicles ( DDEV)during driving, this paper proposes a driving torque distribution strategy with a certain dual motor vehicle as the research object. Research on coordinated control during the operation of two motors is conducted. A DDEV vehicle model in Cruise software is built and joint simulation is conducted with the strategy model built in Simulink software. Simulation testing is conducted under NEDC and WLTC cycle conditions. Our simulation results show the energy consumption of the dual motor vehicle using this strategy is reduced by 6. 7％ and 4. 5％ respectively under two cycle conditions, and the proportion of the two motors operating in the efficient range is increased by 12 . 4％ and 47 . 3％ respectively compared with the data of the front and rear motor drive torque sharing strategy. The average efficiency of the entire vehicle motor under two cycle conditions is accordingly increased by 14. 2％ and 17. 8％, demonstrating its effectiveness in improving electric vehicles' energy efficiency.关键词
