摘要
针对汽车EPS系统安全性与可靠性的要求,开发了一套汽车EPS试验台测控系统。为了使实验台更好地实现实际应用,用电液系统加载的方式代替了传统的弹簧加载,实现了符合实际路况的阻力模拟。基于LabVIEW软件平台所设计的系统具有数据采集、信号发生、信号控制、数据分析功能,实现了系统的自动化。该系统成功地应用于北斗星系列的EPS助力转向特性的检测。实验结果表明,所设计的汽车EPS试验台测控系统动态性能良好。
The measurement and control system of automobile EPS test bench is developed to fit the requirement of security and dependability. The traditional spring loading system is replaced by electro-hydraulic loading system for simulating steering resistance, in order to practise in test bench. Basd on LabVIEW, the system carries out automation consist of mainly functions, such as data acquirement, signal production, signal control and data disposal. The proposed system is successfully applied to Beidouxing EPS testing of power steering characteristics. The experiment results show that the system can run with a good dynamic performance.
