标准摘要
[中文适用范围]： 指定 VAN 的数据链路层和物理层，VAN 是道路车辆应用的高达 125 kbit/s 的通信网络。 VAN是一种面向访问方法的多主多从设备，它允许通过处理远程传输请求的特殊方法（保留对介质的访问以允许插入响应）来优化请求/响应管理。 定义了网络的总体架构和数据链路层的内容，以及道路车辆上不同类型电子模块之间传输的物理层。 [外文原描述]： Specifies the data link layer and the physical layer of the VAN, a communications network up to 125 kbit/s, for road vehicle application. The VAN is an access-method oriented multimaster-multislave which allows optimized request/response management by special method of handling a remote transmission request (retaining access to the medium to allow insertion of a response). Defines the general architecture of the network and the content of the data link layer, and the physical layer for transmission between different types of electronic modules on board road vehicles.
英文名称Road vehicles — Low-speed serial data communication — Part 3: Vehicle area network (VAN)
