Bluetooth™ Wireless Protocol for Automotive Applications

2001-12-31
HISTORICAL
J2561_200112
This SAE Information Report defines the functionality of typical Bluetooth applications used for remotely accessing in-vehicle automotive installations of electronic devices. Remote access may be achieved directly with on-board Bluetooth modules, or indirectly via a custom designed gateway that communicates with Bluetooth and non-Bluetooth modules alike. Access to the vehicle, in the form of two-way communications, may be made via a single master port, or via multiple ports on the vehicle. The Bluetooth technology may also be used in conjunction with other types of off-board wireless technology. This report recommends using a message strategy that is already defined in one or more of the documents listed in 2.1.1, 2.1.4, 2.1.5, and 2.1.6. Those strategies may be used for some of the typical remote communications with a vehicle. It is recognized, however, that there may be specific applications requiring a unique message strategy or structure.

CURRENT
J2057/4_202212
The subject matter contained within this SAE Information Report is set forth by the Class A Task Force of the Vehicle Network for Multiplexing and Data Communications (Multiplex) Committee as information the network system designer should consider. The Task Force realizes that the information contained in this report may be somewhat controversial and a consensus throughout the industry does not exist at this time. The Task Force also intends that the analysis set forth in this document is for sharing information and encouraging debate on the benefits of utilizing a multiple network architecture.

CURRENT
J2057/3_202212
The Class A Task Force of the Vehicle Network for Multiplexing and Data Communications Subcommittee is providing information on sensors that could be applicable for a Class A Bus application. Sensors are generally defined as any device that inputs information onto the bus. Sensors can be an input controlled by the operator or an input that provides the feedback or status of a monitored vehicle function. Although there is a list of sensors provided, this list is not all-inclusive. This SAE Information Report is intended to help the network system engineer and is meant to stimulate the design thought process.

Class B Data Communications Network Interface

2022-12-20
CURRENT
J1850_202212
This SAE Standard establishes the requirements for a Class B Data Communication Network Interface applicable to all On-and OffRoad Land-Based Vehicles. It defines a minimum set of data communication requirements such that the resulting network is cost effective for simple applications and flexible enough to use in complex applications. Taken in total, the requirements contained in this document specify a data communications network that satisfies the needs of automotive manufacturers. This specification describes two specific implementations of the network, based on media/Physical Layer differences. One Physical Layer is optimized for a data rate of 10.4 Kbps while the other Physical Layer is optimized for a data rate of 41.6 Kbps (see Appendix A for a checklist of application-specific features). The Physical Layer parameters are specified as they would be detected on the network media, not within any particular module or integrated circuit implementation.

CURRENT
J2962-2_202402
This document covers the requirements for transceiver qualification. Requirements stated in this document will provide a minimum standard level of performance for the CAN transceiver in the IC to which all compatible transceivers shall be designed. No other features in the IC are tested or qualified as part of this recommended practice. This will assure robust serial data communication among all connected devices, regardless of supplier. The goal of SAE J2962-2 is to commonize approval processes of CAN transceivers across OEMs. The intended audience includes, but is not limited to, CAN transceiver suppliers, component release engineers, and vehicle system engineers.

CURRENT
J2962-3_202402
This SAE Recommended Practice covers the requirements for ethernet physical layer (PHY) qualification (and as applicable to other high-speed networks [i.e., Audio Bus, LVDS, Ser-Des, etc.]). Requirements stated in this document provide a minimum standard level of performance for the PHY in the IC to which all compatible ethernet communications PHY shall be designed. When the communications chipset is an ethernet switch with an integrated automotive PHY (xBASE-T1), then the testing shall include performance for all switch PHY ports as well as each controller interface. No other features in the IC are tested or qualified as part of this SAE Recommended Practice. This assures robust serial data communication among all connected devices regardless of supplier. The goal of SAE J2962-3 is to commonize approval processes of ethernet PHYs across OEMs. The intended audience includes, but is not limited to, ethernet PHY suppliers, component release engineers, and vehicle system engineers.

GLOSSARY OF VEHICLE NETWORKS FOR MULTIPLEXING AND DATA COMMUNICATIONS

HISTORICAL
J1213/1_199106
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.

J2284/2_202305
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 250 kbps 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 250 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 Electronic Control Unit (ECU) requirements defined in Section 6 are met, then the system level attributes should be obtainable.
