19、16ISO 13400-3:2016(E)IntroductionVehicle diagnostic communication has been developed starting with the introduction of the first legislated emissions-related diagnostics and has evolved over the years, now covering various use cases ranging from emission-related diagnostics to vehicle-manufacturer-s

20、pecific applications like calibration or electronic component software updates.With the introduction of new in-vehicle network communication technologies, the interface between the vehicles electronic control units and the test equipment has been adapted several times to address the specific charact

21、eristics of each new network communication technology requiring optimized data link layer definitions and transport protocol developments in order to make the new in-vehicle networks usable for diagnostic communication.With increasing memory size of electronic control units, the demand to update thi

22、s increasing amount of software and an increasing number of functions provided by these control units, 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 an

23、d real-time networks (like FlexRay, MOST), which cannot be adapted to provide the direct interface to a vehicle. This requires gateways to route and convert messages between the in-vehicle networks and the vehicle interface to test equipment.The intent of ISO 13400 (all parts) is to describe a stand

24、ardized vehicle interface which separates in-vehicle network technology from the external 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 communi

25、cation standard usable for legislated diagnostic communication, as well as for manufacturer-specific use cases, and can easily be adapted to new physical and data link layers, including wired and wireless connections, by using existing adaptation layers.To achieve this, all parts of ISO 13400 are ba

45、onEthernet is a collection of several standards for different transmission technologies and speeds contained in IEEE 802.3 and is a frame-based networking technology for wired local area networks. Frames are defined as the format of data packets on the wire. The Internet Protocol (IPv4) theoreticall

46、y allows for a maximum IP packet length of 64 Kbytes. This size is limited by the Ethernet specification, which defines a 16-bit-length field and requires a minimum packet length of 64 bytes, as well as allowing for a maximum payload length of 1 500 bytes. Consequently, IP packets can have a maximum

47、 length of only 1 500 bytes on Ethernet. However, IP allows for fragmentation of IP packets over multiple Ethernet frames to work around this limitation. The rules for fragmentation of IP packets differ between IPv6 and IPv4 and are not specified in this document.The Ethernet connection of a vehicle

48、 works with four transmission lines in accordance with IEEE 802.3 100BASE-TX, as well as using an additional activation line. The Ethernet controller in the DoIP Edge Node can be switched on and off via the activation line when the test equipment is connected to, or disconnected from, the vehicle. I

In this case, the pins of each RJ45 connector of the patch cable or the cable to the vehicle connector are directly connected to each other (e.g. Rx+ on the source port is connected to Rx+ on the destination port). cross-linked connection, which is usually used to connect t
