摘要
文章以非线性轮胎模型和7自由度整车动力学模型为基础,在Labview平台建立转向阻力矩动力学模型,转角信号作为输入,使用LabVIEW RT(实时)模块,将这些模型程序下载到实时目标硬件PXI上运行,结合硬件接口电路控制电液比例控制器,继而驱动液压加载装置来模拟转向阻力矩。试验结果表明,设计的硬件在环试验台可用于EPS基本特性的测试、试验和EPS控制器的开发、参数调整。
Based on the nonlinear tire model and seven-degree freedom vehicle dynamic model, the steering resistance torque dynamics model is established based on the Labview platform. The steering angle signal is used as the input, the Labview RT module is used to download the modular program to the real-time target hardware PXI and control the electrohydraulic proportional controller with the hardware interface circuit, and then the hydraulic loading devices are driven to simulate the steering resistance torque. The results show that the designed hard-in-the-loop（HIL） platform can be applied in the test of the characteristics of EPS, and the development and parameters control of EPS controller.
