44、16ISO 17987-6:2016(E)IntroductionISO 17987 (all parts) specifies the use cases, the communication protocol and physical layer requirements of an in-vehicle communication network called Local Interconnect Network (LIN).The LIN protocol as proposed is an automotive focused low speed universal asynchro
45、nous receiver transmitter (UART) based network. Some of the key characteristics of the LIN protocol are signal based communication, schedule table based frame transfer, master/slave communication with error detection, node configuration and diagnostic service transportation.The LIN protocol is for l
46、ow cost automotive control applications, for example, door module and air condition systems. It serves as a communication infrastructure for low-speed control applications in vehicles by providing: signal based communication to exchange information between applications in different nodes; bit rate s
47、upport from 1 kbit/s to 20 kbit/s; deterministic schedule table based frame communication; network management that wakes up and puts the LIN cluster into sleep state in a controlled manner; status management that provides error handling and error signalling; transport layer that allows large amount
48、of data to be transported (such as diagnostic services); specification of how to handle diagnostic services; electrical physical layer specifications; node description language describing properties of slave nodes; network description file describing behaviour of communication; application programme
49、rs interface.ISO 17987 (all parts) is based on the open systems interconnection (OSI) basic reference model as specified in ISO/IEC 7498-1 which structures communication systems into seven layers.The OSI model structures data communication into seven layers called (top down) application layer (layer 7), presentation layer, session layer, tran
