摘要
为完成电动助力转向系统(EPS)的实车道路试验,设计了EPS辅助测试系统,包括测试系统的硬件设计方案和软件实现方法.利用该测试系统可以采集EPS控制过程中各种信息,为EPS控制策略和控制参数的修改提供依据.数据由基于MC68HC908GP32单片机的数据采集板采集后,以SCI方式发送到上位机.在上位机编写了用户操作界面,可实现实时波形显示、数据存储、历史波形回放等功能.使用结果表明,该系统满足EPS实车道路试验的数据采集需要.
To finish vehicle road experiment of EPS, An EPS assistant testing system is proposed in this paper, and with giving hardware project and corresponding software chart. The system can receive signals of the progress of EPS control, which can help amending control strategy. These signals were send to PC by SCI method. Complied a software in PC, it displays real time shape, saves receive data and displays saved shape and so on. The system is able to satisfy the need of EPS vehicle road experiment.
