【摘要】 参照SAEJ1939协议设计了燃料电池客车的CAN通信协议,并利用CANoe进行仿真以评估其性能。结合整车和各个节点(电机、DC/DC、燃料电池和蓄电池)的数学模型,通过仿真对比了定周期、周期有误差、事件触发、有错误帧以及最坏情况等情况下总线负载变化,验证了协议的正确性和有效性。为车载网络实时通信系统的实际设计提供了参考依据,能降低开发成本并缩短开发周期。更多还原

【Abstract】 A CAN communication protocol for the fuel cell bus was designed according to SAE J1939 protocol and it was simulated in CANoe to evaluate its performance. The model of each node was set up in order to make the simulation vivid. The loads of bus in many different kinds of conditions were compared and the protocol was proved by simulation based on the models. This work gives a reference design to cut the cost and shorten the period of the exploitation.更多还原
