AFS硬件在环测试平台开发

摘要

In this article, general architecture of Hardware-in-the-loop (HIL) test-bench is built based on the requirements of AFS ECU. Then the hardware is constructed with PXI technical route, and software is developed with Veristand environment. Finally, the HIL test-bench is integrated. Meanwhile, test stimuli for dimming function is also designed. The result indicates that the platform has good function of the HIL simulation for AFS, and realizes the testing for AFS controller while satisfying precision and timeliness requirements.%分析AFS ECU测试需求，建立了硬件在环测试平台的总体架构；采用PXI技术路线搭建了系统硬件，基于Veristand环境开发了系统软件，最终对硬件在环测试平台进行集成；针对AFS的上下调光功能和左右调光功能分别设计了测试激励。测试结果表明：该平台具有良好的AFS硬件在环仿真功能，能在满足测试精度和实时性要求的基础上，实现对AFS控制器的测试。
