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.

This SAE Information Report will explain the differences between Class A, B, and C networks and clarify through examples, the differences in applications. Special attention will be given to a listing of functions that could be attached to a Class A communications network.

The objective of this document is to define a minimum set of physical and data link layer requirements applicable to a vehicle data communication network that is cost effective for simple applications and flexible enough to use in complex applications. Network requirements "above" the physical and data link layers are generally application specific and are, therefore, left to the system designer. The requirements contained in this document define a data communications network philosophy that satisfies the needs of the automotive manufacturers. In its present form, this document defines a cohesive set of data link layer requirements. On the other hand, several alternative physical layer approaches are specified to accommodate a variety of application requirements.
This SAE Recommended Practice establishes the requirements for a Class B Data Communication Network Interface applicable to all on and off-road land based vehicles. This document 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. Although this document addresses all seven layers of the OSI model, it primarily focuses on the Network, Data Link and Physical Layers. Taken in total, the requirements contained in this document specify a data communications network philosophy that satisfies the needs of automotive manufacturers. Although the higher layer OSI requirements are essentially identical for all networks defined by this document (see Section 3.3, Figure 1), differing data rate requirements necessitate the use of different physical layers.
This SAE Recommended Practice establishes the requirements for a Class B Data Communication Network Interface applicable to all On and Off-Road 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. Additionally, this document outlines one Physical Layer alternative to the two fully defined implementations that may allow the network to operate at a 125 Kbps data rate.
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.
