摘　　要：基于CCP协议，开发了一套为EPS提供在线匹配标定与数据采集系统，并着重对CAN总线网络信号传输进行建模，分析了整车网络多节点情况下EPS系统的信号传输，保证上位机的标定与数据采集不受整车网络影响。通过匹配EPS相关的参数使之可以适应于不同的转向系，以达到所需的助力效果，并能通过数据采集模块得知关键数据实时变化情况，为下一次的标定提供数据支持。Based on CCP agreement, develop a set of online matching calibration and data collection system tor EPS,focus on modeling of CAN network signal transmission,analyse EPS system signal transmission for vehicle network multi nodes,guarantee the calibration and data collection of upper machine position will not be effected by vehicle network.Through related parameters of EPS matching to make it to be suitible for different steering system, so as to achieve the desired effect,and learn key data real-time tranform through data collection mode,provide data support for the following calibration.
