14、(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 a subject for which a
15、 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 Commission (IEC) on all matte

23、, as specified in ISO 14229-1, on UART-based local interconnect networks (UDSonLIN).To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model specified in ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers. When mapped on thi
24、s model, the services specified by ISO 14229 are divided into the following. Application layer (layer 7), unified diagnostic services specified in ISO 14229-1, ISO 14229-3 UDSonCAN, ISO 14229-4 UDSonFR, ISO 14229-5 UDSonIP, ISO 14229-6 UDSonK-Line, ISO 14229-7 UDSonLIN, further standards, and ISO 27

32、cal interconnect networks in road vehicles. The UDSonLIN diagnostics defines methods to implement diagnostic data transfer between a client and the LIN slave nodes through the LIN master node.LIN slave nodes support three different diagnostic classes as defined in ISO 17987.UDSonLIN references ISO 1
33、4229-1 and ISO 14229-2 and specifies implementation requirements of the following: diagnostic services to be used for diagnostic communication over LIN, server memory programming for in-vehicle LIN servers with an external test equipment, and configuration of a LIN slave node as specified in ISO 179
34、87.NOTE UDSonLIN does not specify any requirement for the in-vehicle LIN bus architecture.This part of ISO 14229 makes reference to information contained in the following: ISO 14229-1, ISO 14229-2, and ISO 17987 (all parts).This part of ISO 14229 does not include any redundant information of the abo
35、ve mentioned documents. It focuses on the following: additional requirements specific to the implementation of UDSonLIN network, and specific restrictions in the implementation of UDSonLIN network.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this

42、lause defines how the diagnostic services, as defined in ISO 14229-1, apply to LIN.To allow a common implementation of application layer and session layer for ISO 17987 and other communications, this part of ISO 14229 uses the session layer protocol as defined in ISO 14229-2 and focuses on necessary
43、 modifications and interfaces to adopt it to ISO 17987- series.The subfunction parameter definitions take into account that the most significant bit is used for the suppressPosRspMsgIndicationBit parameter as defined in ISO 14229-1.It is the vehicle manufacturers responsibility to setup the LIN mast
44、er and slave nodes to exchange UDSonLIN information according to ISO 17987- series.6.2 Definition of diagnostic classes6.2.1 OverviewArchitectural, diagnostic communication performance, and transport protocol needs of slave nodes are accommodated by dividing diagnostic services functionality into th
45、ree diagnostic classes.Therefore, a diagnostic class is assigned to each slave node according to its level of diagnostic functionality and complexity.6.2.2 Diagnostic class ISmart and simple devices like intelligent sensors and actuators requiring none or very low amount of diagnostic functionality.
46、 Actuator control, sensor reading, and fault memory handling is done by the master node, using signal carrying frames. Therefore, specific diagnostic support for these tasks is not required. Fault indication is always signal-based.6.2.3 Diagnostic class IIA diagnostic class II slave node is similar
47、to a diagnostic class I slave node, but it provides node identification support. The extended node identification is normally required by vehicle manufacturers. Testers or master nodes use ISO 14229-1 diagnostic services to request the extended node identification information. Actuator control, sens
48、or reading, and fault memory handling is done by the master node, using signal carrying frames. Therefore, specific diagnostic support for these tasks is not required. Fault indication is always signal-based.6.2.4 Diagnostic class IIIDiagnostic class III slave nodes are devices with enhanced applica
49、tion functions typically performing their own local information processing (e.g. function controllers, local sensor/actuator loops). The slave nodes execute tasks beyond the basic sensor/actuator functionality and, therefore, require extended diagnostic support. Direct actuator control and raw sensor data are often not exchanged with the master node and, therefore, not included in signal carrying frames.
