Survey of Known Protocols

1993-04-01
HISTORICAL
J2056/2_199304
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.

Class A Multiplexing Sensors

2006-09-12
CURRENT
J2057/3_200609
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 A Multiplexing Actuators

2006-09-12
CURRENT
J2057/2_200609
The Class A Task Force of the Vehicle Network for Multiplex and Data Communications Committee is publishing this SAE Information Report to provide insight into Class A Multiplexing. Multiplexed actuators are generally defined as devices which accept information from the multiplexed bus. A multiplexed actuator can be an output device controlled by the operator or an intelligent controller. A Multiplex actuator can also be a display device that reports the status of a monitored vehicle function. This document is intended to help the network system engineers and is meant to stimulate the design thought process. A list of multiplexed actuator examples is provided in Appendix A, Figure A1. Many other examples can be it identified.

J2178/1_201104
This SAE Recommended Practice defines the information contained in the header and data fields of non-diagnostic messages for automotive serial communications based on SAE J1850 Class B networks. This document describes and specifies the header fields, data fields, field sizes, scaling, representations, and data positions used within messages. The general structure of a SAE J1850 message frame without in-frame response is shown in Figure 1. The structure of a SAE J1850 message with in-frame response is shown in Figure 2. Figures 1 and 2 also show the scope of frame fields defined by this document for non-diagnostic messages. Refer to SAE J1979 for specifications of emissions related diagnostic message header and data fields. Refer to SAE J2190 for the definition of other diagnostic data fields. The description of the network interface hardware, basic protocol definition, the electrical specifications, and the CRC byte are given in SAE J1850.

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.
