5、 Truck and Bus Electrical and Electronics Committee.The objectives of the subcommittee are to develop information reports,recommended practices,and standards concerned with the requirements,design,and usage of devices that transmit electronic signals and control information among vehicle components.

6、The usage of these Recommended Practices is not limited to truck and bus applications;other applications may be accommodated with immediate support being provided for construction and agricultural equipment,and stationary power systems.These SAE Recommended Practices are intended as a guide toward s

7、tandard practice and are subject to change so as to keep pace with experience and technical advances.This application layer may be used for all SAE J1939 applications.It is the characteristic that is common across all SAE J1939 applications.TABLE OF CONTENTS 1 Scope.4 2 References.4 2.1 Applicable P

36、 set of messages.5.1 General The definitions provided herein are intended to satisfy the needs of all potential users of the SAE J1939 network.These definitions are intended to be suitable for applications in any of the industry groups defined within SAE J1939.The capabilities provided allow CAs to

37、configure and identify to other network CAs the location of certain parameters(each identified by its SPN)within certain special messages(each identified by PGN).These capabilities also provide the means by which a CA can request the identification of the message(PGN)containing a certain parameter(S

38、PN).This document will define the configuration process,a set of messages which can and may be configured,and the messages used to identify this configuration to the rest of a network.This document will also contain the definitions of the only set of parameters(identified by SPN)to be used exclusive

39、ly within one of the configured messages defined herein.It is intended that these parameters be completely defined within this document before use on a network.New features,Parameter Groups and Parameter definitions will be added over time;it is anticipated that this document will continuously evolv

40、e as long as the SAE J1939 network is an active Recommended Practice.Such growth will be implemented in such a way as to ensure backward compatibility with earlier versions.At the time of initial publication,many of these growth areas are identified but are yet to be defined.Such identification is p

41、rovided so that the reader will be aware of those additions that are already planned for the document.This procedure will define a number of messages that may be configured,presently there are 16 configurable PDU 1 messages.5.2 Overview of Configuration Services The configuration messages and proces

42、ses are intended to provide services needed to improve utilization of bus bandwidth,facilitate organization of data within messages in a fashion that can allow optimization of vehicle topology,and allow identification of this organization to other CAs.5.2.1 DEVELOPMENTAL HISTORY These messages were

43、originally proposed for Agricultural Applications,but have been harmonized and standardized for all Industry Groups.In the Agricultural Industry specific example,self-propelled vehicles with very different topologies need to use common parameters,so that third party vendors can know the identity of

44、parameters on the networks.But the message groupings must fit the vehicle topology in order to have sufficient time to transmit all of the parameters.For this Agricultural need it is desired that the source and destination addresses,as well as,the message configuration,be used to identify the data C

45、opyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-SAE J1939-74 Issued SEP2004 -6-within a particular message(just as source and destination address are needed to identify the data within the proprietary

46、 A message identified in SAE J1939-21).These messages need to be configurable in the sense that the groupings of parameters within a message were not predefined within one of the network standard documents,but by the data within another message(the Proprietary Message Configuration Identification Me

47、ssage).The parameters being used are to be predefined within this network document,just as other parameters are defined within one of the other network documents.The Agricultural need was limited to destination specific messages and thus the original proposal was tailored to that end.Several revisio

48、ns studied allowing other messages,but committee work has deemed it best to maintain this restriction,that the only configurable messages are destination specific messages.The new aspect of this document is the technique by which the grouping of certain parameters(defined within this standard)can be

49、 arranged appropriately for the vehicle topology and then identified to other network members by a configuration process,using the data content of a special initialization message.This configuration process identifies the message being configured(by PGN),the parameters being sent within said message

50、(by SPN),as well as their placement within said message(by bit position).After some discussion it was deemed that the feature could be handy for all Industry Groups and a working group was sent out to develop a harmonized version.5.2.2 HARMONIZATION These messages have been harmonized for use in all
