This SAE Information Report is a summary comparison of existing protocols found in manufacturing, automotive, aviation, military, and computer applications which provide background or may be applicable for Class C application. The intent of this report is to present a summary of each protocol, not an evaluation. This is not intended to be a comprehensive review of all applicable protocols. The form for evaluation of a protocol exists in this paper and new protocols can be submitted on this form to the committee for consideration in future revisions of this report. This report contains a table which provides a side-by-side comparison of each protocol considered. The subsequent section provides a more detailed examination of the protocol attributes. Many of the protocols do not specify a method for one or more of the criteria. In these circumstances 'under defined' or 'not specified' will appear under the heading.

This SAE Recommended Practice defines the Physical Layer and portions of the Data Link Layer of the OSI model for data communications. In particular, this document specifies the physical layer requirements for any Carrier Sense Multiple Access/Collision Resolution (CSMA/CR) data link which operates on a single wire medium to communicate among Electronic Control Units (ECU) on road vehicles. Requirements stated in this document will provide a minimum standard level of performance to which all compatible ECUs and media shall be designed. This will assure full serial data communication among all connected devices regardless of supplier. This document is to be referenced by the particular vehicle OEM Component Technical Specification which describes any given ECU in which the single wire data link controller and physical layer interface is located. Primarily, the performance of the physical layer is specified in this document.

This SAE Information Report studies the present transmission media axioms and takes a fresh look at the Class C transmission medium requirements and also the possibilities and limitations of using a twisted pair as the transmission medium. The choice of transmission medium is a large determining factor in choosing a Class C scheme.

This document covers the tests to be performed on all SAE J2602-1 (2021 revision) devices. Tests described in this document will ensure a minimum standard level of performance to which all compatible electronic control units (ECUs) and media shall be designed. This will assure full serial data communication among all connected devices regardless of supplier. The goal of SAE J2602-2 is to improve the interoperability and interchangeability of LIN devices within a network by verifying the devices pass a minimum set of tests. To allow for easy cross-reference, this document is arranged such that the conformance test for a given section in SAE J2602-1 (2021 revision) is in the same section in SAE J2602-2. This document is to be referenced by the particular vehicle original equipment manufacturer (OEM) component technical specification that describes any given ECU in which the LIN data link controller and physical layer interface is located.

This document covers the tests to be performed on all J2602-1 defined Master and Slave nodes.

This document covers the requirements for SAE implementations based on ISO 17987:2016. Requirements stated in this document will provide a minimum standard level of performance to which all compatible ECUs and media shall be designed. This will assure full serial data communication among all connected devices regardless of supplier. The goal of SAE J2602-1 is to improve the interoperability and interchangeability of LIN devices within a network by adding additional requirements that are not present in ISO 17987:2016 (e.g., fault tolerant operation, network topology, etc.). The intended audience includes, but is not limited to, ECU suppliers, LIN controller suppliers, LIN transceiver suppliers, component release engineers, and vehicle system engineers. The term “master” has been replaced by “commander” and term “slave” with “responder” in the following sections.

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.

SAE has many vehicle network "J" documents to analyze and select from. Many vehicle network architectures have an overlap of characteristics that can apply to several networks.

This document covers the general terms and corresponding definitions that support the design, development, implementation, testing, and application of vehicle networks. The terminology also covers some terms and concepts of distributed embedded systems, network hardware, network software, physical layers, protocols, and other related areas.

This SAE Information Report provides definition for terms (words and phrases) which are generally used within the SAE in describing network and data communication issues. In many cases, these definitions are different from those of the same or similar terms found in nonautomotive organizations, such as the Institute of Electrical and Electronic Engineers (IEEE). The Vehicle Networks for Multiplexing and Data Communications committee has found it useful to collect these specific terms and definitions into this document so documents related to the multiplexing and data communications issues will not need an extensive definitions section. This document is intended to be the central reference for terms and definitions related to multiplexing and data communications and as such is intended to apply equally to Passenger Car, Truck and Bus, and Construction and Agriculture organizations within SAE.
