Road vehicles - Functional safety

📅 Issue date：2018 🔄 Effective date：2018 🌍 Type：国际标准（功能安全）

📑 Table of Contents

01 Scope

ISO 26262 specifies functional safety requirements for E/E systems (safety-related) in road vehicles across concept, system, hardware and software life cycle, using ASIL (A~D) and a V-model development process.

02 Normative references

  1. ISO 26262-1 Vocabulary
  2. ISO 26262-3 Concept
  3. ISO 26262-4 System
  4. ISO 26262-5 HW
  5. ISO 26262-6 SW
  6. ISO 26262-8 Supporting
  7. IEC 61508

03 Terms and definitions

ASIL
Automotive Safety Integrity Level (A lowest ~ D highest) from severity, exposure, controllability.
HARA
Hazard Analysis and Risk Assessment deriving ASIL.

04 Technical requirements

Safety life cycle
Concept→system→HW/SW→production→operation with phase-specific safety activities.
ASIL decomposition
Higher ASIL requirement split into redundant lower-ASIL elements (independence required).
HW metrics
SPFM, LFM meet ASIL targets; PMHF random HW failure target.
SW requirements
Modularity, defensive programming, fault-injection, tool confidence (TCL).
