道路车辆.扩展车辆（ExVe）时间关键应用.与道路和ExVe安全（RExVeS）有关的时间限制情况的一般要求 定义和分类方法

[中文适用范围]： 本文件定义了时间受限情况的分类方法及其要求，这些要求将由 ISO 20077-1 中描述的“ExVe 时间关键接口”解决。时间受限情况包括安全关键情况。为了满足时间受限情况的要求，车辆设计必须优先管理“ExVe 时间关键接口”资源。该方法提供了一种分类，可确定应用优先级，以实现车辆资源的最佳分配。 [外文原描述]： This document defines the classification methodology of time-constrained situations and their requirements, that are to be addressed by the "ExVe time critical interfaces" described in ISO 20077‑1. Time-constrained situations include safety-critical situations. It is important for the design of the vehicle to have priority management of "ExVe time critical interface" resources in order to comply with time constrained situations requirements. The methodology provides a classification, which determines application priorities for optimal vehicle resource allocation.
