摘要
阐述CAN规范和SAE J1939协议;SAE J1939是适用于货车和客车的应用层协议,对于混合动力汽车却没有统一的应用层协议。本文参照SAE J1939协议格式制定出适用于混合动力汽车(HEV)的应用层协议;结合混合动力汽车的控制特点,提出了CAN总线和LIN总线并用的双总线控制方法;通过实验测试了混合动力汽车CAN总线通信性能。实验结果表明,通信网络性能满足控制的实时性要求。
This paper describes the CAN specification and SAE J1939 protocol. SAE J1939 protocol is designed for trucks and buses, it is not suitable for HEV. The authors design a type of application layer protocol for HEV based on SAE J1939. Aimed at the control characteristic of HEV, double control modes are put forward, that is CAN bus and LIN bus. An experiment about the CAN bus communication performance is done on the HEV, and the result shows that the communication network performance satisfies the real-time request for control.
