2014 年第 3 期电动轮驱动电动汽车动力系统测试试验台研究*【摘要】介绍了所设计的电动轮驱动电动汽车动力系统测试试验台的结构原理及功能。该试验台利用 CAN 总线网络实现控制信息的交互,可编程逻辑控制器(PLC)实现整体控制,基于虚拟仪器 LabVIEW 实现了上位机的实时监控与显示界面。提出了 1 号电机转矩控制、2 号电机转速跟随的控制策略,并通过双轮独立驱动模式直线行驶试验验证了控制策略的有效性,结果表明该试验台能够满足设计要求。主题词:电动汽车双轮独立驱动动力系统控制策略中图分类号:+2 文献标识码:A 文章编号:1000-3703(2014)03-0031-04Research on the Test Bench for Powertrain System ofElectric-wheel Driving EVXu Dawei, Li Dongdong, Tian Shaopeng(Hubei Key Laboratory of Advanced Technology of Automotive Parts, Wuhan University of Technology)【Abstract】This paper introduces the development of the test bench for power train system of electric-wheel drivingEV. The structure principle and functions of the test bench are highlighted. The whole test bench uses CAN workto achieve the interaction of the control information, and uses programmable logic controller (PLC) for the integral PC real-time monitoring and display interface is developed based on virtual apparatus LabVIEW. In the end, thecontrol strategy for motor 1 torque control and motor 2 speed following has been proposed, which is validated by straightdriving test with two-wheel independent driving mode, the results show that the test bench can fully meet the words:EV, Two-wheel independent drive, Power train,Control strategy徐达伟李东东田韶鹏(武汉理工大学现代汽车零部件技术湖北省重点实验室)觹基金项目:国家科技部“863”项目(2011AA11A260),湖北省研究与开发计划项目(2011FAA007)。1 前言在能源与环境的双重压力下,
