ISO 23132-2020 pdf free.Road vehicles — Extended Vehicle(ExVe) time critical applications —General requirements, definitions andclassification methodology of time-constrained situations related to Roadand ExVe Safety (RExVes).
1.This document defines the classification methodology of time-constrained situations and theirrequirements, that are to be addressed by the”ExVe time critical interfaces” described in ISO 20077-1.Time-constrained situations include safety-critical 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 vehicleresource allocation.
2.Normative references:The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document. For dated references, only the edition cited applies.Forundated references, the latest edition of the referenced document (including any amendments) applies.
The RExVeS methodology brings forward means to identify and classify time-constrained situations(safety-critical or not) that are addressed by the”ExVe time critical interfaces” described in ISO 20077-1.The methodology provides an automotive-specific risk-based approach to determine the priority classof a RExVeS-related time-constrained situation. It is adapted from IS0 26262-3El hazard analysis andrisk assessment (HARA) and enriched with systems-theoretic process analysis (STPA) insights. Themajor difference is that in IS0 26262-3El, the results of the analysis are ASILs while in this documentthe results are time-constrained situation priority classes.
NOTE1 The appropriate use of the RExVeS methodology is intended to fulfil RExVeS-related requirementsand a set of connected vehicle design prerequisites (see Clause 7).
NOTE2 Unless otherwise stated, in this document, connected vehicle means connected vehicle taking intoaccount ISO 20077-1 and ISO 20077-2.
The RExVeS methodology starts with the analysis of road safety-related connected vehicle scenariosin which time-constrained situations (safety-critical or not) may occur. Then, a systematic evaluation of each identified time-constrained situation is performed to determine the RExVeS-related situationpriority class to which it pertains. The RExVeS-related situation priority class is determined byconsidering severity, probability of exposure and controllability criteria.ISO 23132 pdf download.
