Road vehicles. Functional safety – Product development at the software level

This document is intended to be applied to safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production road vehicles, excluding mopeds. This document does not address unique E/E systems in special vehicles such as E/E systems designed for drivers with disabilities.
NOTE Other dedicated application-specific safety standards exist and can complement the ISO 26262 series of standards or vice versa.
Systems and their components released for production, or systems and their components already under development prior to the publication date of this document, are exempted from the scope of this edition. This document addresses alterations to existing systems and their components released for production prior to the publication of this document by tailoring the safety lifecycle depending on the alteration. This document addresses integration of existing systems not developed according to this document and systems developed according to this document by tailoring the safety lifecycle.
This document addresses possible hazards caused by malfunctioning behaviour of safety-related E/E systems, including interaction of these systems. It does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release of energy and similar hazards, unless directly caused by malfunctioning behaviour of safety-related E/E systems.
This document describes a framework for functional safety to assist the development of safety-related E/E systems. This framework is intended to be used to integrate functional safety activities into a company-specific development framework. Some requirements have a clear technical focus to implement functional safety into a product; others address the development process and can therefore be seen as process requirements in order to demonstrate the capability of an organization with respect to functional safety.
This document does not address the nominal performance of E/E systems.
This document specifies the requirements for product development at the software level for automotive applications, including the following:
-
general topics for product development at the software level;
-
specification of the software safety requirements;
-
software architectural design;
-
software unit design and implementation;
-
software unit verification;
-
software integration and verification; and
-
testing of the embedded software.
It also specifies requirements associated with the use of configurable software.
Annex A provides an overview on objectives, prerequisites and work products of this document.
