SAE J2284-5-201609是关于CAN FD（柔性数据速率）通信技术的一个标准文档，其主要内容和知识点可以概括为以下几个方面： 1. 标准目的和应用场景：SAE J2284-5标准的主要目的是为了在车辆与离线工具之间进行数据通信时使用CAN FD消息格式，通过定义500kbps的仲裁总线以及CAN FD数据在5Mbps的速率下通信，实现一种标准化的实现方法。这种标准化能够使电子控制单元（ECU）和工具制造商满足多个最终用户的需求，同时只需对基本设计进行最少的修改。 2. 技术要求和性能参数：文档中详细说明了汽车应用中高速CAN（HSC）的数据通信速率，即在500kbps下进行仲裁，并在5Mbps下传输CAN FD数据。该标准指定了ECU的物理层、数据链路层以及介质设计的标准要求，以确保制造商生产出能够满足不同用户需求的ECU，而且能从基本设计的大规模生产中获益，降低ECU成本。 3. 网络系统级属性：此标准涉及了网络的多种属性，如消息格式、通信速率、基本通信网络参数、拓扑结构和终端配置以及在故障情况下的通信/生存能力。 4. 通信速率：SAE J2284-5文档中特别强调了通信速率的重要性。在500kbps的速率下进行消息的仲裁，并在5Mbps的速率下传输数据，这种高速数据传输能力对于需要高带宽的数据交互应用来说至关重要。 5. CAN协议：控制器局域网络（CAN）协议是被广泛应用于车辆电子设备之间通信的一种网络协议。SAE J2284-5标准在现有的CAN协议基础上，进一步定义了在高速率下的数据通信模式，这有助于提高车载系统的性能和效率。 6. 终端和拓扑结构：文档中还讨论了网络的拓扑结构和终端配置。例如，可能涉及到单个车载ECU配置，以及在不使用屏蔽介质的情况下的通信要求。 7. 附加要求：除了基本要求之外，该标准可能还会提出额外的技术要求，以适应特定的环境或应用。 8. 故障条件下的通信：在文档中还会讨论在故障条件下如何保证通信的持续性和系统的生存能力。 9. 知识产权声明：文档明确指出，SAE技术标准的使用完全是自愿的，使用该标准的适用性和适宜性，包括因此产生的任何专利侵权，完全由用户自行负责。SAE技术报告至少每五年审查一次，在此期间，它可能会被修订、重新确认、稳定化或取消。 SAE J2284-5-201609标准文档通过这些详细的要求和参数，旨在为车辆内部的数据通信提供一个高度标准化和高效可靠的通信平台，推动车辆通信技术的发展，并确保不同制造商的设备能够相互兼容与通信。由于文档是通过OCR扫描得出的，可能存在个别字词识别错误或遗漏，但上述内容概括了标准的核心概念和关键知识点。

RECOMMENDED PRACTICE

J2284™-5

SEP2016

Issued 2016-09

High-Speed CAN (HSC) for Vehicle Applications at 500 kbps with CAN FD Data

at 5 Mbps

RATIONALE

Facilitate usage of the CAN with Flexible Data Rate (CAN FD) message format for data communication between a vehicle

and off board tools.

FOREWORD

The objective of SAE J2284-5 is to define a level of standardization in the implementation of a 500 kbps arbitration bus with

CAN FD Data at 5 Mbps for a point to point connection between a vehicle and off board tools using the Controller Area

Network (CAN) protocol. The goal is to achieve a standard Electronic Control Unit (ECU) Physical Layer, Data Link Layer,

and Media Design Criteria which will allow ECU and tool manufacturers to satisfy the needs of multiple end users with

minimum modification to a basic design. Likewise, end users will benefit in lower ECU cost achieved from the high volumes

of the basic design.

1. SCOPE

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 5 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.

Requirements will focus on a minimum standard level of performance from the High-Speed CAN (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 arbitration bus with CAN FD Data at 5 Mbps. The minimum

performance level shall be specified by system level performance requirements or characteristics described in detail in

Section 6 of this document.

This document is designed such that if the Electronic Control Unit (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.
