前、后双电机车辆动力系统匹配选型研究

Research on Matching and Selection of Vehicle Power System with Front and Rear Double Motors

纯电动四驱车辆,集良好的动力性能、通过性能、舒适性、环保性等优点于一身,因此在我国“碳达峰碳中和”规划的大背景下,四驱动力构型的纯电动汽车具有良好的市场前景。本文章以某款前、后双电机纯电动四驱开发车型为例,介绍了前、后双电机动力系统匹配流程,在满足车辆动力性设计目标的前提下结合工程实际对车辆前、后电机扭矩进行分配,并结合仿真软件验证设计计算的正确性与合理性。为前、后双电机系统的选型工作提供参考。

Pure electric four-wheel drive vehicles combine the advantages of good power performance,passing performance,comfort,and environmental protection.Therefore,under the background of my country’s"carbon peak and carbon neutral"plan,pure electric vehicles with four driving forces Automobiles have good market prospects.Taking a certain front and rear dual-motor pure electric four-wheel drive development model as an example,this article introduces the matching process of the front and rear dual-motor power system.Under the premise of meeting the vehicle dynamics design goal,the torque of the front and rear motors of the vehicle is combined with the actual engineering.Assign and verify the correctness and rationality of the design calculations combined with simulation software.Provide reference for the selection of front and rear dual-motor systems.
