14、ervedISO 11898-1:2003(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in

15、a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commissi

16、on (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical com

17、mittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not

18、be held responsible for identifying any or all such patent rights.ISO 11898-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,Electrical and electronic equipment.-,-,-This first edition of ISO 11898-1, together with ISO 11898-2, replaces ISO 11898:1993, which has been

19、 technically revised. Whereas the replaced International Standard covered both the CAN DLL and the high- speed PL, ISO 11898-1 specifies the DLL, including LLC and MAC sublayers, as well as the PLS sublayer, while ISO 11898-2 specifies the high-speed MAU.ISO 11898 consists of the following parts, un

22、AL STANDARDISO 11898-1:2003(E)Road vehicles Controller area network (CAN) Part 1:Data link layer and physical signalling1 ScopeThis part of ISO 11898 specifies the data link layer (DLL) and physical signalling of the controller area network (CAN): a serial communication protocol that supports distri

23、buted real-time control and multiplexing for use within road vehicles. While describing the general architecture of CAN in terms of hierarchical layers according to the ISO reference model for open systems interconnection (OSI) established in ISO/IEC 7498-1, it provides the characteristics for setti

24、ng up an interchange of digital information between modules implementing the CAN DLL itself specified according to ISO/IEC 8802-2 and ISO/IEC 8802-3 with detailed specification of the logical link control (LLC) sublayer and medium access control (MAC) sublayer.2 ConformanceThe conformance of the DLL

During simultaneous transmission of dominant and recessive bits, the resulting

33、 bus state is dominant. When no transmission is in progress, the bus is idle. During that time it is in the recessive state.4.8contention-based arbitrationCSMA arbitration procedure where simultaneous access of multiple nodes results in a contention4.9framedata link PDU specifying the arrangement an
