Core Standards
ISO 26262 — Functional Safety (Road Vehicles)
- Edition: 2nd edition (2018), 12 parts
- Scope: Safety of E/E systems — addresses systematic failures and random hardware failures
- Key concepts: ASIL (A-D), safety lifecycle, safety case, V-model development
- Limitation for AD: Designed for driver-in-the-loop; does not fully address AI/ML, SOTIF, or L4+ systems
- Parts most relevant to AD:
- Part 3: Concept phase (HARA)
- Part 4: Product development at system level
- Part 6: Product development at software level
- Part 11: Guidelines on application to semiconductors
- Part 12: Adaptation for motorcycles (less relevant)
Key Processes:
- HARA → Safety Goals → Functional Safety Requirements → Technical Safety Requirements
- Safety Validation (Part 4, Clause 8)
- Confirmation measures (safety audits, safety assessments)
ISO 21448 — SOTIF (Safety of the Intended Functionality)
- Published: 2022
- Scope: Addresses hazards from functional insufficiencies and triggering conditions (NOT component failures)
- Key concepts: Areas 1-4 (known/unknown × safe/unsafe), triggering conditions, functional insufficiencies
- Critical for AD: Directly addresses perception limitations, AI/ML uncertainty, sensor limitations
SOTIF vs ISO 26262:
| Aspect | ISO 26262 | ISO 21448 |
|---|
| Hazard source | Component malfunction | Intended function limitation |
| Example | Sensor hardware failure | Sensor misclassifies object |
| Coverage | Systematic + random failures | Performance limitations + misuse |
| ASIL concept | ASIL A-D | Not ASIL-based (separate risk assessment) |
| AI/ML | Not addressed | Partially addressed |
Key Clauses:
- Clause 5: Specification and design of intended functionality
- Clause 6: Identification and evaluation of triggering conditions
- Clause 7: Evaluation and validation of residual risk
- Clause 8-10: Functional modifications, verification, validation
UL 4600 — Safety Case Framework for Autonomous Products
- Published: 2020 (Edition 1), updated 2022 (Edition 2)
- Scope: Provides a framework for constructing safety cases; does NOT prescribe specific metrics
- Key innovation: Addresses the full AD stack including AI/ML, data, simulation, and operational safety
- Structure: Goal-based safety argumentation (GSN/CAE)
Key Topics Covered:
- Safety case construction (claims, arguments, evidence)
- AI/ML safety (training data, edge cases, ODD monitoring)
- Simulation and testing adequacy
- Tool qualification and data integrity
- Risk assessment and residual risk acceptance
- Operational safety and fleet management
- Human factors (for L2/L3 systems)
ISO/PAS 8800 — Safety and AI for Road Vehicles
- Status: Published 2024
- Scope: Guidance for applying AI safely in road vehicles
- Key topics: Data quality, model verification, robustness, explainability, monitoring
- Relationship: Intended to support ISO 26262 and ISO 21448 for AI-specific concerns
Key Areas:
- AI development lifecycle for automotive
- Data management (collection, labeling, quality)
- AI model properties (robustness, accuracy, uncertainty)
- Verification and validation of AI components
- AI-specific failure modes and mitigations
- Runtime monitoring and OOD detection
ISO 34502 — Scenario-Based Safety Evaluation Framework
- Published: 2022
- Scope: Framework for scenario-based safety evaluation of AD systems
- Key concepts: Scenario layers, test case derivation, coverage criteria
- Complements: ISO 34503 (taxonomy for ODD)
ISO 34503 — Taxonomy for ODD
- Published: 2023
- Scope: Standard taxonomy for describing ODD attributes
- Categories: Scenery, environmental conditions, dynamic elements, digital information
SAE J3016 — Levels of Driving Automation
- Latest: 2021 revision (SAE J3016_202104)
- Defines: Levels 0-5 of driving automation
- Key distinctions:
- L0-L2: Driver performs DDT; ADAS features
- L3: ADS performs DDT; driver must be fallback-ready (OEDR by driver on request)
- L4: ADS performs DDT within ODD; achieves MRC if ODD exit
- L5: ADS performs DDT unconditionally (no ODD limitation)

Research Gaps in Current Standards
- AI/ML validation: ISO 26262 insufficient for ML; ISO/PAS 8800 is guidance only
- Foundation models: No standard addresses LLM/VLM use in AD
- End-to-end AD: Standards assume modular architecture; no guidance for E2E systems
- Simulation validity: No accepted standard for sim-to-real transfer fidelity
- Long-tail safety: Statistical insufficiency for proving safety of rare events
- Multi-ADS interaction: Standards focus on single ADS; fleet/mixed traffic not addressed
- Cybersecurity-safety integration: ISO 26262 and ISO 21434 lack unified framework
- Data-driven safety case: Evidence standards for data-driven safety arguments underdefined
- Ethical decision-making: No binding technical standard for ethical dilemmas
- Cross-jurisdiction harmonization: Fragmented regulatory landscape
