Road vehicles - Local Interconnect Network (LIN) - Part 1: General information and use case definition 1 Scope This document gives an overview of the structure and the partitioning of GB/T 42691. In addition, it outlines the use case where the GB/T 42691 will be used. The terminology defined in this document is common for all LIN communication systems and is used throughout GB/T 42691. This document has been established in order to define the use cases for LIN. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
