摘要:: 为了研究轮毂电机驱动电动汽车的操纵稳定性，设计开发一款具有4轮转向和4轮驱动的电动车辆试验平台，基于LabVIEW开发了试验平台的测控系统。针对直线加速和方向盘角阶跃输入等试验工况，利用该样车平台进行了控制算法的快速控制原型和道路试验测试研究，并对电子差速算法实验结果进行分析。试验结果表明，该平台能够进行电子差速和车辆操纵稳定性测试，满足设计功能要求，能验证控制策略的有效性以及评估控制算法的优劣性，为分布式驱动电动车辆的控制算法开发及其操纵稳定性分析评估奠定了良好的基础。

Abstract:: In order to study the handling stability of electric vehicle driven by hub motor,an electric vehicle test platform with four-wheel steering and four-wheel driving was designed and developed.This paper introduces the overall layout of the test platform,the working principle of the measurement and control system,and the hardware assembly.By using LabVIEW,a test and control system for the test platform was developed.Finally,for the experimental conditions,such as linear acceleration and angle step input of steering wheel angle,this experiment platform was used to carry out rapid control prototype and road test of control algorithm.The test results show that the platform can perform electronic differential and vehicle handling stability tests,meet the design function requirements,verify the effectiveness of the control strategy and evaluate the advantages and disadvantages of the control algorithm,which lays a good foundation for the development of control algorithms for distributed-drive electric vehicles and the analysis and evaluation of their handling stabilities.
