标准摘要
[中文适用范围]： ISO 10681 的这一部分规定了为满足 FlexRay 通信系统协议规范中指定的基于 FlexRay 的车辆网络系统的要求而定制的通信协议的要求。 由于通信协议结合了网络层和传输层功能（OSI 第 3 层和第 4 层），因此 ISO 10681 的这一部分没有明确区分这些层服务。 [外文原描述]： ISO 10681-2:2010 specifies the requirements for a communication protocol tailored to meet the requirements of FlexRay-based vehicle network systems as specified in the FlexRay Communications Systems Protocol Specification. As the communication protocol combines the network-layer and transport-layer functionality (OSI layers 3 and 4), this document does not explicitly distinguish between these layer services. The technical features of this communication protocol are as follows: transmit messages with known data length; transmit messages with unknown but finite data length; additional acknowledgement with retry mechanism; routing data on the fly; support of dynamic frame length.
