18、ion of the first legislated emission-related diagnostics and has evolved over the years, now covering various use cases ranging from emission-related diagnostics to vehicle manufacturer specific applications like calibration or electronic component software updates.With the introduction of new in-ve
19、hicle network communication technologies, the interface between the vehicles electronic control units and the external test equipment has been adapted several times to address the specific characteristics of each new network communication technology requiring optimized data link layer definitions an
20、d transport protocol developments in order to make the new in-vehicle networks usable for diagnostic communication.With increasing memory size of electronic control units and the demand to update this increasing amount of software and an increasing number of functions provided by these control units
21、, technology of the connecting network and buses has been driven to a level of complexity and speed similar to computer networks. New applications (x-by-wire, infotainment) require high band-width and real time networks (like FlexRay, MOST), which cannot be adapted anymore to be the direct interface
22、 to a vehicle. This requires gateways to route and convert messages between the in-vehicle networks and the vehicle interface to external test equipment.The intent of the ISO 13400 series is to describe a standardized vehicle interface which separates in-vehicle network technology from the external
23、test equipment vehicle interface requirements to allow for a long-term stable external vehicle communication interface, utilizes existing industry standards to define a long-term stable state-of-the-art communication standard usable for legislated diagnostic communication, as well as for manufacture
24、r specific use cases, and can easily be adapted to new physical and data link layers by using existing adaptation layers.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
25、into seven layers. When mapped on this model, the services specified by ISO 14229 series are divided into: unified diagnostic services (layer 7), specified in ISO 14229-1, ISO 14229-5, ISO 27145-3; presentation (layer 6): for enhanced diagnostics, specified by the vehicle manufacturer; for WWH-OBD,

31、Diagnostic communication over Internet Protocol (DoIP) Part 4: Ethernet-based high-speed data link connector1 ScopeThis part of ISO 13400 specifies a minimum set of diagnostic Ethernet connector requirements which are based on ISO 15031-3. The ISO 15031-3 diagnostic connector is referenced by legisl
32、ation in many countries.The diagnostic connection specified in this part of ISO 13400 consists of two mating connectors: the vehicle connector and the external test equipment connector as specified in ISO 15031-3.This part of ISO 13400 specifies: the functional requirements for the vehicle connector
33、. These functional requirements are separated into two principal areas: connector contact allocation and electrical requirements for connector and related electrical circuits; the functional requirements for the external test equipment connector. These functional requirements are separated into two
34、principal areas: connector contact allocation and electrical requirements for connector and related electrical circuits.Two (2) different connector layouts and pin-outs are specified in this part of ISO 13400:a) Ethernet pin assignment option 1 (see Annex A);b) Ethernet pin assignment option 2 (see
35、Annex B).Historically, option 1 is specified to meet Ethernet pin assignment of road vehicles already launched onto the market and may be used to resolve conflicts with vehicle manufacturer-specific usage of discretionary pins, e.g. pins 1 and 9.Option 2 is specified to meet the Ethernet pin assignm
36、ent of road vehicles to resolve conflicts with vehicle manufacturer-specific usage of discretionary pins, e.g. pins 3 and 11.A discovery/identification and activation method of the vehicles Ethernet via the “Ethernet Activation Line” is specified in ISO 13400-3.2 Normative referencesThe following do

This is needed to meet
46、 the in-vehicle electrical architecture design.Discovery/identification of the vehicles Ethernet option (configuration) is a requirement for external test equipment in order to properly connect to the Ethernet without causing any damage either to the vehicles or external test equipment bus circuitry
47、. In addition, any bus interference like bus errors shall be avoided.The solution for external test equipment to identify the vehicles Ethernet option is based on reading the vehicles identification signal provided on the “Ethernet activation line” available on the diagnostic connector prior to enab
