标准范围

ISO 22902-4:20 06提供了一种通信模型，该模型包含通过AMI-C网络的网络传输协议访问车辆接口的车辆接口协议(VIP)的要求。它不适用于具有用于传输车辆功能的预先存在的协议和消息的网络。VIP定义了应用程序如何通过简单的网络传输机制进行通信。这些要求可以应用于使用UDP/IP作为传输方法的网络技术。然而，预先存在的系统可以具有用于传输关于车辆功能的消息的唯一协议和消息；因此，ISO 22902-4:20 06不涵盖此类预先存在的技术。传输的消息是CMS的网络特定实例。ISO 22902-4:20 06解决了与AMI相关的以下方面-C的网络通信方式:消息帧格式、应用事务、系统事务、初始化过程、地址解析、功能模块发现和删除过程。

ISO 22902-4:2006 provides a communication model that contains the requirements for a Vehicle Interface Protocol (VIP) to access a vehicle interface over a network transport protocol for AMI-C networks. It does not apply to networks that have pre-existing protocols and messages for transporting vehicle functions.A VIP defines how an application communicates over a simple network transport mechanism. These requirements can be applied to network technologies that use UDP/IP as the transport method. However, pre-existing systems may have unique protocols and messages for transporting messages about vehicle functions; therefore, ISO 22902-4:2006 does not cover such pre-existing technology.Messages transported are network-specific instantiations of the CMS.ISO 22902-4:2006 addresses the following aspects related to the AMI-C's approach to network communication:

• Message frame format,
• Application transaction,
• System transaction,
• Initialization process,
• Address resolution, and
• Functional module discovery and removal process.
