Overview

ISO/TR 4804:2020 - "Road vehicles - Safety and cybersecurity for automated driving systems - Design, verification and validation" - provides a technical framework and guidance for developing, verifying and validating automated driving systems (ADS) with SAE J3016:2018 Level 3 and Level 4 capabilities. The report emphasizes safety-by-design and cybersecurity-by-design, describes dependability attributes, and closes the loop with verification and validation (V&V) methods to demonstrate a positive risk balance and avoidance of unreasonable risk.

Key topics and technical scope

Safety and cybersecurity principles: guidance on achieving a positive risk balance, avoiding unreasonable risk, and integrating safety and cybersecurity objectives.

Dependability-driven development: deriving ADS capabilities from dependability domains (reliability, availability, maintainability, safety, security - RAMSS).

Standards alignment: references and alignment with related standards such as ISO/PAS 21448 (SOTIF), ISO 26262 (functional safety) and ISO/SAE 21434 (automotive cybersecurity).

ADS capabilities and elements: discussion of capabilities, minimal risk conditions and maneuvers, elements to implement capabilities, and a generic logical architecture.

Verification & validation (V&V): end-to-end V&V scope and steps, including defining test goals, test design techniques, platforms, and strategies to address key challenges.

Key V&V challenges:

Statistical demonstration of risk reduction without driver intervention
System safety for driver interaction and takeover maneuvers
Handling unknown or novel scenarios (corner cases)
Validation across multiple configurations and variants
Validation of machine learning–based subsystems

Testing methods: simulation types and validation of simulation, scenario-based testing, equivalence classes, and quantity/quality of testing.

Sub-system verification: perception, localization (GNSS), sensor fusion, interpretation/prediction, motion control, HMI and user-state monitoring.

Field operation: traceability, configuration/change management, regression prevention, and continuous cybersecurity monitoring and updates.

Informative annexes: development examples, use of deep neural networks, principles of safety/cybersecurity, and a proposed standards list.

Practical applications - who uses this standard

OEMs and Tier‑1/Tier‑2 suppliers designing Level 3/4 ADS

System architects, safety and cybersecurity engineers implementing safety-by-design and security-by-design

V&V teams, test labs and simulation providers developing test strategies and scenario libraries

Regulators and compliance teams evaluating demonstrations of risk mitigation
