车载网络手册 对电子系统设计工程师而言,汽车工业正在进入一个令人鼓舞而充满挑战的时期,诸如信息娱乐、遥感测试、安全和控制等应用需要若干种联网标准。CAN是控制器局域网络(Controller Area Network, CAN)的简称,是由研发和生产汽车电子产品著称的德国BOSCH公司开发的,并最终成为国际标准(ISO11898)。
关于CAN物理层的讨论 Many network protocols are described using the seven layer Open System Interconnection (OSI) model, as
shown in Figure 1. The Controller Area Network (CAN) protocol defines the Data Link Layer and part of the
Physical Layer in the OSI model. The remaining physical layer (and all of the higher layers) are not defined by
the CAN specification. These other layers can either be defined by the system designer, or they can be implemented
using existing non-proprietary Higher Layer Protocols (HLPs) and physical layers.
