About ISO 26262 (Automotive Functional Safety)

This online session delivers expert-led instruction on the regulatory landscape and implementation approach for ISO 26262.

ISO 26262 adapts functional safety to road vehicles: a lifecycle from item definition and hazard analysis (HARA) through system, hardware and software development, production, operation and decommissioning, with integrity expressed as ASIL A-D.

What it regulates

Safety lifecycle management, HARA and ASIL determination, functional and technical safety concepts, hardware metrics (SPFM/LFM/PMHF), software development rigor, supporting processes (configuration, tools, safety analyses) and confirmation measures.

Who must comply

OEMs, tier suppliers, and semiconductor vendors delivering E/E systems for series production road vehicles.

Key requirements of ISO 26262

  • Part 3: concept phase — item definition, HARA, functional safety concept
  • Part 4: system-level development and technical safety concept
  • Part 5: hardware — architectural metrics and evaluation of random failures
  • Part 6: software development
  • Part 8: supporting processes incl. tool qualification and qualification of components
  • Part 9: ASIL-oriented analyses (decomposition, dependent failures)
  • Part 11: application to semiconductors

Key concepts: ISO 26262

SPFM/LFM/PMHF
Hardware architectural metrics: single-point and latent fault coverage plus probabilistic metric targets per ASIL.
ASIL (A-D)
Automotive Safety Integrity Level from HARA parameters severity, exposure and controllability — D the most stringent.
ASIL decomposition
Splitting a requirement across sufficiently independent elements at lower ASILs with evidence of independence.
HARA
Hazard Analysis and Risk Assessment on vehicle-level hazardous events determining ASILs and safety goals.
Safety goal
Top-level safety requirement per hazardous event, parent of the functional safety concept.

Frequently asked questions: ISO 26262

Does ISO 26262 cover autonomous driving hazards?

It covers malfunction-caused hazards. Hazards from functional insufficiencies without failure (perception limits, scenario gaps) are the domain of ISO 21448 SOTIF, used together with 26262 for automated driving.

How do ASIL and SIL relate?

They are siblings from IEC 61508 but not convertible: ASIL derives from automotive-specific S/E/C parameters and drives different hardware metrics and process tables. Cross-domain reuse requires re-derivation, not a mapping table.

What is a safety element out of context (SEooC)?

A component (chip, software library, sensor) developed against assumed requirements before the vehicle context exists; the integrator must validate the assumptions of use against the actual item.
