Understanding ISO 26262
ISO 26262 is an international standard developed to ensure that safety-critical systems in automotive applications achieve and maintain a high level of safety throughout their lifecycle. It covers various aspects of safety, including:
- Management of functional safety: Establishing safety goals, safety lifecycle, and safety management processes.
- Safety concept development: Defining safety requirements and creating safety concepts.
- System design and implementation: Developing architectures and designs that meet safety requirements.
- Verification and validation: Conducting activities to ensure that systems perform as intended and meet safety standards.
- Safety assessment: Reviewing and assessing the safety of the system before it is deployed.
ISO 26262 is divided into several parts, each addressing different components of functional safety, including guidelines for hardware, software, and system-level safety.
