摘　　要：通过对基于CAN总线控制系统的燃料电池车水泵测试实验数据的分析,着重研究了CAN总线信号的发送与接收周期对水泵转速的影响,找出了燃料电池车PCU水泵偶停的关键因素,对后续燃料电池车的CAN总线通讯设计及故障排除问题有一定的指导意义。Through the analysis of the experimental data of fuel cell vehicle pump testing on CAN bus control system, the influence between the transmission cycle of CAN bus signal and pump speed received is focused emphatically. The key factors that affect the performance of PCU pump in fu- el cell vehicles are found, which has a certain guiding significance for the future design and trouble- shooting of the fuel cell vehicle CAN bus communication.
