本文给出了一种基于CAN总线的网络管理(NM)在车载系统中的实现。需要说明的是,虽然车身控制模块(BCM)在网络管理中处于主节点地位并负责多路CAN的交互(即网关),但如无特殊说明,文中所描述的网络管理机制应在所有电子控制单元(ECU)中统一实施,而不仅仅限于车身控制部分。本文只讨论车身CAN(Body-CAN,B-CAN)网络管理,传动CAN网络(Powertrain-CAN,P-CAN)的管理本文不作论述。
This paper presents a CAN bus-based network management (NM) in the vehicle system. It should be noted that although the Body Control Module (BCM) is the master node in network management and is responsible for the interaction of multiple CANs (ie, gateways), the network management mechanisms described in this paper should be implemented in all electronic controls Unit (ECU) in a unified implementation, not just limited to the body control section. This article only discusses the body-CAN (CAN-CAN) network management, transmission CAN network (Powertrain-CAN, P-CAN) management is not discussed in this article.
