一种车载CAN网络通讯可靠性保障机制

A mechanism of reliability guarantee of automotive CAN network communication

总线技术的发展带动了车载网络的应用,CAN总线在汽车行业中已被广泛使用.但由于CAN总线的争用特性,当在CAN总线上发生大规模的ECU总线争用时,有可能对通信的可靠性造成影响.本文深入分析了车载网络通讯的特点,根据工程经验提出了一种用于车载CAN网络的通讯可靠性保障机制,该机制对网络消息进行均散化并设定参考时基,有效的保障了车载CAN网络通讯的可靠性.

Bus technology brings about the application of the automotive network,and CAN bus in the automotive industry is widely used.However,the reliability of communication will decrease when CAN bus contention takes place.Based on the analysis of the automotive network traffic,this paper proposes a novel method to solve the problem,which uses the time base and schedules meassages to protect the reliability of automotive network effectively.
