5、8-09 Revised 2015-06 Superseding J1939-82 AUG2008 Compliance RATIONALE This document has been revised to include new tests for recent changes to associated SAE J1939 documents, update cross references to the document section in the associated SAE J1939 documents, and add clarification to the test de

6、scriptions. The new tests have been added to cover changes made recently to the SAE J1939-21, SAE J1939-31, and SAE J1939-81 documents. Test descriptions and test names have been update for many of the tests associated with the SAE J1939-21 and SAE J1939-31 documents primarily for clarification. The

7、 tests listed in Tables A5, A6, A7, and A8 were reordered to keep together existing and new tests for similar aspects. FOREWORD The SAE J1939 communications network is defined using a collection of individual SAE J1939 documents based upon the layers of the Open System Interconnect (OSI) model for c

8、omputer communications architecture. The SAE J1939-82 document describes the compliance tests and procedures to verify an SAE J1939 ECU will operate correctly on a SAE J1939 network. This compliance document may be used for SAE J1939 applications. The SAE J1939 communications network is a high speed

9、 ISO 11898-1 CAN based communications network that supports real-time closed loop control functions, simple information exchanges, and diagnostic data exchanges between Electronic Control Units (ECUs) physically distributed throughout the vehicle. The SAE J1939 communications network is developed fo

10、r use in heavy-duty environments and suitable for horizontally integrated vehicle industries. The SAE J1939 communications network is applicable for light-duty, medium-duty, and heavy-duty vehicles used on-road or off-road, and for appropriate stationary applications which use vehicle derived compon

11、ents (e.g., generator sets). Vehicles of interest include, but are not limited to, on-highway and off-highway trucks and their trailers, construction equipment, and agricultural equipment and implements. The physical layer aspects of SAE J1939 reflect its design goal for use in heavy-duty environmen

12、ts. Horizontally integrated vehicles involve the integration of different combinations of loose package components, such as engines and transmissions, that are sourced from many different component suppliers. The SAE J1939 common communication architecture strives to offer an open interconnect syste

13、m that allows the ECUs associated with different component manufacturers to communicate with each other. SAE INTERNATIONAL J1939-82 Revised JUN2015 Page 2 of 62 TABLE OF CONTENTS 1. SCOPE 3 2.

SCOPE SAE J1939-82 Compliance describes th

18、e compliance tests and procedures to verify an SAE J1939 ECU will operate correctly on a SAE J1939 network. The purpose of these compliance procedures is to generate one or more test documents that outline the tests needed to assure that an ECU that is designed to operate as a node on a SAE J1939 ne

19、twork would do so correctly. SAE does not certify devices and these tests and their results do not constitute endorsement by SAE of any particular device. These tests are presented to allow testing of a device to determine self-compliance by the manufacturer of a device. The manufacturer can use its

20、 record of what procedures were run successfully to show the level of compliance with SAE J1939. 2.

ABBREVIATIONS BAM Broadcast Announce Message CA Controller Application CAI Controller Application Identity CTC Compliance Test Computer DUT Device Under Test 5. EQUIPMENT The Standard Test Configuration will

30、 contain two nodes, the Compliance Test Computer (CTC) and the Device Under Test (DUT), with appropriate media and termination, as well as power supplies and DUT loads. 5.1 Compliance Test Computer (CTC) A Compliance Test Computer with the following capabilities: 5.1.1 Message transmission Must be a

31、ble to send any specified message. 5.1.2 Message reception Must be able to receive all bus messages. 5.1.3 Time stamp Must be able to time stamp at the beginning of received messages at the required resolution. SAE INTERNATIONAL J1939-82 Revised JUN2015 Page 5 of 62 5.1.4 Time resolution Must posses

32、s a minimum time resolution of 10 microsecond. The actual time resolution must be specified. 5.1.5 Time stamp accuracy The error between any two timestamps shall be less than 1% of the time difference between the two timestamps or 1 millisecond, whichever is greater. 5.1.6 Time stamp latency error M

33、ust be less than 1 count of the time resolution. 5.1.7 Transmission synchronization Must be able to control the time between messages it transmits. 5.1.8 Reception timeout In cases where DUT should have no response the CTC must be able to monitor that no response message is transmitted by the DUT fo

34、r a minimum time equal to the allowed transmission response time plus two times the allowed latency (for example when transmission should be within 200 milliseconds and 50 millisecond latency is allowed then CTC must check for a minimum time of 300 milliseconds). Longer times are at the discretion o

35、f the designers. 5.1.9 CAN interface At least one CAN interface is required. Two CAN interfaces are required for testing Bridge functions. 5.2 Device under test (DUT) The Device Under Test with the following features: 5.2.1 Operation Must be able to perform its normal intended use (not operating any

36、 special testing mode of operation). 5.2.2 Controls Must be able to initiate the action under test when directed. 6. SETUP The setup will consist of a minimum network with two nodes. Any additional requirements for a specific test procedure will be specified within that procedure. 6.1 Minimum Networ

37、k Two nodes, the DUT and the CTC, with terminations, a short length of the appropriate media, power supplies. 6.2 Message Traffic Minimal normal network traffic, only the messages necessary for the specific test procedure (see 5.2.1). 6.3 Test Message Set Messages that are applicable to a specific t

38、est procedure will be listed in the test outline. This message list will be broken into two pieces: those supported for reception and those supported for transmission. SAE INTERNATIONAL J1939-82 Revised JUN2015 Page 6 of 62 7. TEST SELECTION The procedure to select a test or set thereof, necessary t

39、o check for compliance to a particular function or set of functions from the standard, are outlined within Appendix A. Appendix A is broken into tables, which identify functions, based on which document section(s) they are described within. Some tests will be pointed to by more than one entry. 7.1 D

40、ocument Identifying Test The specific document identifying a particular function will be outlined with any necessary cross-references within a Table for the specific task force document. 7.2 Requirement versus Device Characteristics The SAE and User Requirements status of each function will be cross

41、 referenced with the Device Characteristics (such as: Arbitrary Address Capable, Command Configurable, Diagnostic Tool, etc.) that will affect whether a device should provide said function. 8. RUNNING A TEST The steps necessary to run a test are outlined as follows: 8.1 Identify Test Using Appendix

42、A the reviewer should identify the test number(s) necessary to check any particular function(s) that they desire. Note that all tests are not applicable to all systems. The “Requiring Document” column refers the reviewer to the appropriate document section the test is intended to cover. 8.2 Report G

43、eneration Using APPENDIX A the reviewer should document the test(s) performed and the results, as well as whether the device had requirement exceptions (additions or exclusions) for each of the particular functions. 9. REPORTING COMPLIANCE TEST RESULTS APPENDIX A contains columns in the forms for re

44、porting the results of compliance testing. These columns are used to report the test date, whether a particular test is required for the specific device being tested and whether the test has been run, as well as whether the device passed (complied with) the test. 9.1 Self-Compliance APPENDIX A is in

45、tended to be used by an OEM as self-compliance documentation. When certifying a device the OEM can indicate whether that the device is intended to provide each function, as well as the general level to which the device is designed. The passage of each function by the particular device can then be do

46、cumented along with the date of testing. The inclusion of the specific test number(s) should enable future comparison among devices, as well as, among testers. 9.2 Device Support The reporting forms record the test(s) conducted, the test results, and whether a device is intended to support a particu

47、lar function, which makes these reporting forms very helpful to a customer locating a desired device. SAE INTERNATIONAL J1939-82 Revised JUN2015 Page 7 of 62 10.
