SCOPE This SAE Recommended Practice defines a document for the format of messages and data that is of genera
21、l value to modules on the data communications link. Included are field descriptions, size, scale, internal data representation, and position within a message. This document also describes guidelines for the frequency of and circumstances in which messages are transmitted. In order to promote compati
22、bility among all aspects of electronic data used in heavy-duty applications, it is the intention of the SAE Truck and Bus Low Speed Communications Network Subcommittee (formerly Data Format Subcommittee) (in conjunction with other industry groups) to develop recommended message formats for: a. Vehic
23、le and Component InformationThis includes all information that pertains to the operation of the vehicle and its components (such as performance, maintenance, and diagnostic data). b. Routing and Scheduling InformationInformation related to the planned or actual route of the vehicle. It includes curr
24、ent vehicle location (for example, geographical coordinates) and estimated time of arrival. c. Driver InformationInformation related to driver activity. Includes driver identification, logs, (for example, DOT), driver expenses, performance, status, and payroll data. d. Freight InformationProvides da
25、ta associated with cargo being shipped, picked up, or delivered. Includes freight status, overage, shortage and damage reporting, billing and invoice information as well as customer and consignee data.This document represents the recommended formats for basic vehicle and component identification and
26、 performance data. This document is intended as guide toward standard practice and is subject to change to keep pace with experience and technical advances. 1.1 Purpose The purpose of this document is to define the format of the messages and data being communicated between microprocessors used in he
27、avy-duty vehicle applications. It is meant to serve as a guide toward a standard practice to promote software compatibility among microcomputer based modules. This document is to be used with SAE J1708. SAE J1708 defines the requirements for the hardware and basic protocol that is needed to implemen
28、t this document. The primary use of the communications link and message format is expected to be the sharing of data among stand-alone modules. It is anticipated that this document (when used in conjunction with SAE J1708) will reduce the cost and complexity associated with developing and maintainin
29、g software for heavy-duty vehicle microprocessor applications. 2.

35、1990 https:/ ELECTRONIC DATA INTERCHANGE All data transmitted on the communication link, defined by SAE J1708, using message identification (MID) in the range 128 to 255, shall follow this document. Designers need to be aware that messages starting with MIDs 0 to 127 are allowed to coexist with curr
36、ent SAE J1587 messages. The content of the messages broadcast by MIDs 0 to 127 may or may not conform to SAE J1587 format. 3.1 Message Format The message shall consist of the following: Message ID One or More Parameters ChecksumThe number of parameters in a message is limited by the total message le
37、ngth defined in SAE J1708. MIDs are assigned to transmitter categories as identified in Table 1. 3.2 MID Assignment List Additions No two transmitters in the system shall have the same MID. System manufacturers may request additions be made to the MID list. The SAE Truck and Bus Low Speed Communicat
38、ions Network Subcommittee will review the value of any additional MIDs for general interest and/or purpose and may or may not add it to the list. 3.2.1 Available MID Space The MID space allocated for assignment and use by SAE J1587 is almost full. In order to allow for the limited additional assignm
39、ent of new MIDs, the SAE Truck and Bus Low Speed Communication Network Subcommittee has taken the following action to partition the SAE J1587 MID data space by industry segment and reclaim unused MIDs.

40、se with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-3.2.1.1 Transportation Industry Partitioning of MIDs (Multiple Assignment of MIDs) Table 1 has been partitioned to identify the intended transportation segments for each MID. Although SAE J1587 is primarily
41、 utilized within Heavy-Duty vehicle applications, it has also been adopted in other transportation segments such as transit bus and marine. In some cases MIDs have been defined differently per transportation segment. Sections a and b describe how to determine the transportation segment of an ECU: a.
42、 PID 342, Transportation Segment Identifier has been established for tools that are used in more than one transportation segment. This PID is used by diagnostic tools to determine the transportation segment of the MID of the responding ECU. b. Legacy devices (prior to June, 2004) may not respond to
43、this message. 3.2.1.2 Dual Naming MIDs are sometimes assigned two names using the following rationale. a. The need for a new MID assignment is very similar to an existing MID. b. The two named devices could not be used simultaneously on the same vehicle network. 3.2.1.3 Reclaiming of Unused MIDs Cer
44、tain MIDs (134, 135, 148, etc.) were assigned in anticipation of their eventual use. These MIDs were never used since no method for dynamically addressing SAE J1587 MIDs on multiple trailers was specified. Reclaimed MIDs are marked in table 1 as “Reclaimed“. In the next publication of this document,
45、 these MIDs will be shown as “Reserved for future assignment by SAE,“ if they have not been assigned new names or the reclaiming has been negated by use in the field of these MIDs. Any concerns of the reclaiming of MID assignments should be brought to the attention of SAE Truck and Bus Low Speed Com
46、munication Network Subcommittee. 3.2.1.4 The Feb2002 version of Table 1 has been preserved for reference in Appendix G.
