摘要
将混合动力汽车的发动机控制器、电机控制器、整车控制器、电池管理单元和仪表显示控制器通过双绞线相连,构成CAN通讯网络,上位机通过PXI-8464接口卡接到CAN总线上,实时读取各控制器的参数及修改控制器中的数据。采用图形化编程语言LabVIEW 9.0开发了混合动力汽车CAN网络监控平台,此平台具有参数实时显示、指令发送、数据保存等功能和良好的人机交互式界面,满足了混合动力汽车CAN网络监控的各种需求。试验表明:系统操作简单明了,数据处理及时可靠,极大地改善了台架性能试验的工作效率。
Connected via twisted pair,the engine controller,motor controller,vehicle controller,battery management unit and instrument display controller constituted CAN communication network.The PC connected with CAN bus via the PXI-8464 interface card,which could get the real-time parameters of each controller and modify the inner data of them.The CAN network monitoring platform for hybrid electric vehicle was developed by graphical programming language LabVIEW9.0.The monitoring platform has the function of real-time parameters displaying,command giving,data saving and interactive human-computer interface,and fully satisfy the requirements of CAN network monitoring for HEV.The experimental results show that the system has high reliability,simple operation,timely data processing,and greatly improved the test rig efficiency.
