基于 LabVIEW 的汽车 EPS 控制器测试系统设计

摘要

针对汽车 EPS 控制器的出厂测试设备存在软件维护性差、测试效率低等缺点，开发了一套新型测试系统。根据EPS 控制器的结构和测试要求，设计了模拟负载( Loadbox)模块、测试夹具模块，并搭建了硬件电路测试平台。将TestStand 管理软件引入到 LabVIEW 测试程序执行过程中，通过配置 TestStand 适配器模块，对软件平台进行优化。经实例验证，所设计的测试系统运行稳定可靠，能够高效地对控制器功能进行测试。%Aiming at the factory test of automobile EPS controller existing defects with poor software maintenance and low effi-ciency,we developed a new type test system.The hardware platform was built,and Loadbox module and fixture block were designed according to EPS controller’s structure and test requirements.The soft platform realized optimization by configure the adapter mod-ule TestStand.Experiment results indicate that the system can test controller efficiently with a stable and reliable operation.
