本SAE推荐规程将定义500 kbps仲裁总线的开放系统互连模型（ISO 7498）的物理层和部分数据链路层，该总线具有2 Mbps高速CAN（HSC）协议实现的CAN FD数据。将规定网络的ECU和媒体设计要求。需求主要涉及CAN物理层的实现。

This SAE Recommended Practice will define the physical layer and portions of the data link layer of the open systems interconnection model (ISO 7498) for a 500 kbps arbitration bus with CAN FD data at 2 Mbps high-speed CAN (HSC) protocol implementation. Both ECU and media design requirements for networks will be specified. Requirements will primarily address the CAN physical layer implementation.
