本文件旨在适用于安全相关系统，该系统包括一个或多个电气和/或电子（E/E）系统，并安装在系列生产道路车辆中，不包括轻便摩托车。本文件不涉及特殊车辆中的独特E/E系统，例如为残疾驾驶员设计的E/E系统。 注:存在其他专用安全标准，可补充ISO 26262系列标准，反之亦然。 发布用于生产的系统及其组件，或在本文件发布日期之前已在开发中的系统及其部件，不属于本版本的范围。 本文件通过根据变更调整安全生命周期，解决了在本文件发布之前发布用于生产的现有系统及其组件的变更。本文件通过调整安全生命周期，解决了未根据本文件开发的现有系统与根据本文件研发的系统的集成问题。 本文件阐述了安全相关E/E系统的故障行为（包括这些系统的相互作用）可能造成的危险。它不涉及与电击、火灾、烟雾、热、辐射、毒性、易燃性、反应性、腐蚀、能量释放和类似危险相关的危险，除非是由安全行为故障直接引起的- 相关E/E系统。 本文件描述了功能安全框架，以帮助开发安全相关E/E系统。该框架旨在用于将功能安全活动集成到公司特定的开发框架中。一些要求有明确的技术重点，以实现产品的功能安全；其他的描述开发过程，因此可以被视为过程需求，以证明组织在功能安全方面的能力。 本文件未涉及E/E系统的标称性能。 本文件规定了汽车应用系统级产品开发的要求，包括以下内容: -系统级产品开发启动的一般主题； -技术安全要求规范； -技术安全概念； -系统架构设计； -项目集成和测试；和 -安全验证。 附件A概述了本文件的目标、前提条件和工作成果。

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 system level for automotive applications, including the following: — general topics for the initiation of product development at the system level; — specification of the technical safety requirements; — the technical safety concept; — system architectural design; — item integration and testing; and — safety validation. Annex A provides an overview on objectives, prerequisites and work products of this document.
