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。受时间限制的情况包括安全关键情况。 对于车辆设计而言，优先管理“ExVe时间关键接口”资源非常重要，以符合时间限制的情况要求。 该方法提供了一种分类，用于确定最佳车辆资源分配的应用程序优先级。

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.
