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.All current amendments available at time of purchase are included with the purchase of this document.
