标准范围
ISO 26262旨在应用于安全相关系统，这些系统包括一个或多个电气和/或电子（E/E）系统，并且安装在最大车辆总质量高达3 500 kg的量产乘用车中。ISO 26262没有解决特殊用途车辆（如为残疾驾驶员设计的车辆）中独特的E/E系统。发布用于生产的系统及其组件，或在ISO 26262发布日期之前已经在开发中的系统及其组件不在范围内。对于基于ISO 26262发布前发布用于生产的系统及其组件的进一步开发或变更，将仅根据ISO 26262开发修改。ISO 26262解决了E/E安全故障行为可能导致的危害-相关系统，包括这些系统的相互作用。它不涉及与电击、火灾、烟雾、热、辐射、毒性、易燃性、反应性、腐蚀、能量释放和类似危害相关的危害，除非是由E/E安全相关系统的故障行为直接引起的。ISO 26262没有说明E/E系统的标称性能，即使这些系统存在专用的功能性能标准（例如主动和被动安全系统、制动系统、自适应巡航控制）。ISO 26262-6:20 11规定了汽车应用软件层面的产品开发要求，包括以下内容:在软件层面启动产品开发的要求，软件安全要求的规范，软件架构设计、软件单元设计与实现，软件单元测试、软件集成和测试，以及软件安全需求的验证。
ISO 26262 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 passenger cars with a maximum gross vehicle mass up to 3 500 kg. ISO 26262 does not address unique E/E systems in special purpose vehicles such as vehicles designed for drivers with disabilities.Systems and their components released for production, or systems and their components already under development prior to the publication date of ISO 26262, are exempted from the scope. For further development or alterations based on systems and their components released for production prior to the publication of ISO 26262, only the modifications will be developed in accordance with ISO 26262.ISO 26262 addresses possible hazards caused by malfunctioning behaviour of E/E safety-related 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 E/E safety-related systems.ISO 26262 does not address the nominal performance of E/E systems, even if dedicated functional performance standards exist for these systems (e.g. active and passive safety systems, brake systems, Adaptive Cruise Control).ISO 26262-6:2011 specifies the requirements for product development at the software level for automotive applications, including the following:
- requirements for initiation of product development at the software level,
- specification of the software safety requirements,
- software architectural design,
- software unit design and implementation,
- software unit testing,
- software integration and testing, and
- verification of software safety requirements.
