用于 500 Kbps 车辆应用的高速 CAN（Hsc

[中文适用范围]： 此 SAE 推荐实践将为 500 KBPS 高速 CAN (HSC) 协议实施定义 ISO 模型的物理层和部分数据链路层。网络的 ECU 和媒体设计要求都将被指定。需求将主要解决 CAN 物理层实现。要求将集中于高速 CAN (HSC) 实施的最低标准性能水平。所有 ECU 和介质的设计均应满足某些组件级要求，以确保 HSC 实现系统级性能达到 50 KBPS。最低性能水平应由本文件第 6 节中详细描述的系统级性能要求或特性来指定。本文件的设计使得如果满足第 6 节中定义的电子控制单元要求，则应可以获得系统级属性。 [外文原描述]： 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 high-speed CAN (HSC) protocol implementation. Both electronic control unit (ECU) and media design requirements for networks will be specified. Requirements will primarily address the controller area network (CAN) physical layer implementation.Requirements will focus on a minimum standard level of performance from the HSC implementation. All ECUs and media shall be designed to meet certain component level requirements in order to ensure the HSC implementation system level performance at 500 kbps. The minimum performance level shall be specified by system level performance requirements or characteristics described in detail in Section 5 of this document.This document is designed such that if the ECU requirements defined in Section 6 are met, then the system level attributes should be obtainable.This document will address only requirements which may be tested at the ECU and media level. No requirements which apply to the testing of the HSC implementation as integrated into a vehicle are contained in this document. However, compliance with all ECU and media requirements will increase the possibility of communication compatibility between separately procured components and will greatly simplify the task of successfully integrating a HSC communication system in a vehicle.Cross Reference: 970295,CISPR25,ISO11898,ISO14229,ISO7498,ISO7637/1,J1113-13,J1113-21,J1113-41,J1213-1,J1930_201703,J1962_201509,J2190,J551-11,J551-15,J551-4
