电动助力转向控制器性能测试系统设计

摘要

为了获得汽车电动助力转向系统控制器（ECU）的基本性能参数，设计开发了一套能够便捷测试不同型号的ECU性能的系统。基于LabVIEW开发平台，通过NI PCI板卡并配合西门子S7－1200系列PLC实现相关的数据采集和实时控制。通过试验验证，系统达到了设计的预期要求，目前产品出厂检测已经开始使用该系统，并将该系统的检测结果作为产品是否合格的依据。%A performance test system is designed and developed in order that fundamental performance parameters of ECU with different models can be gotten conveniently and accurately.Data acquisition and real-time control of the entire system is based on LabVIEW development platform and NI PCI board card combined with Siemens PLC (S7-1200).Through experimental verification, the system meets the requirements.
