摘　　要：基于虚拟仪器LabVIEW平台组建了车辆稳定性控制(VSC)硬件在环系统。采用滑模变结构控制算法设计了汽车稳定性控制策略;采用LabVIEW图形化程序设计VSC控制程序,并以ARM7嵌入式系统开发了电子控制单元(ECU);在LabVIEW中建立了七自由度非线性整车模型和制动系统模型;利用PXI的硬件接口将压力传感器、方向盘转角传感器等信号引入整车模型,计算车辆的行驶参数,并通过CAN总线发送给ECU,实现闭环控制;采用虚拟现实技术创建整车和环境的3D模型,并与LabVIEW相连接,使硬件在环测试结果更加直观。仿真结果证实了该硬件在环平台的有效性。A hardware-in-the-loop system of VSC was built based on LabVIEW.The sliding mode variable structure control strategy was employed for VSC,the VSC ECU was designed based on ARM7,and the program was designed based on LabVIEW.A nonlinear 7 DOF vehicle model and the brake system model were built based on LabVIEW.The signals from wheel cylinder power sensors and steering wheel angle sensor were collected through PXI I/O to compute the vehicle driving parameters by vehicle model.The parameter feedback from vehicle model was transported to ECU through CAN-bus.Based on the virtual reality technology,a 3D model of vehicle and environments were built,and connected to LabVIEW.The simulation results verify the effectiveness of the VSC hardware-in-the-loop system.
