带增程器电动汽车动力总成系统CAN总线通讯协议制定与测试

Designing and Testing Controller Area Network Protocol for Powertrain System of Electric Vehicles with Range-Extender

结合带增程器电动汽车动力系统的结构特点,制定出相对应的CAN总线通讯协议,并用CANoe进行仿真测试验证该协议的稳定性及可靠性,结果表明各节点均能够及时可靠地发送和接收信息,总线负载率较低,总线运行情况良好,本协议的制定是符合设计要求的.

Considering the characteristics of powertrain system of electric vehicles with range-extender,the Protocol controller area network was given and validated by CANoe.The result presents that messages are transferred and received promptly and reliably in each node,the load rate is low and the CAN bus is well running.It＇s proved that the protocol is feasible.
