ISO 26262-12:2018

Overview

ISO 26262-12:2018 - "Road vehicles - Functional safety - Part 12: Adaptation of ISO 26262 for motorcycles" adapts the ISO 26262 functional safety framework specifically for motorcycle applications. The standard targets safety-related systems that include one or more electrical and/or electronic (E/E) systems in series-production motorcycles (excluding mopeds). It provides guidance for tailoring the ISO 26262 safety lifecycle to motorcycle-specific constraints and use cases, including integration of existing systems and alterations to production systems.

Key topics and requirements

• Scope and applicability: Covers safety-related E/E systems installed in series-production motorcycles; excludes certain special vehicles and hazards not caused by E/E system malfunction (e.g., generic fire, toxicity, unless directly caused by malfunction).
• Adaptation objectives: Tailors lifecycle activities and requirements from the broader ISO 26262 series to motorcycle architecture, development and operational characteristics.
• Safety culture: Requires organizational measures to establish and maintain a safety-aware development environment appropriate for motorcycle manufacturers and suppliers.
• Confirmation measures: Specifies verification and validation activities, independent confirmation requirements and evidence needed to demonstrate functional safety compliance.
• Hazard analysis & risk assessment (HARA): Provides motorcycle-specific guidance for initiating HARA, identifying hazardous events, classifying hazards and determining safety goals and ASILs (Automotive Safety Integrity Levels).
• Vehicle integration & testing: Addresses integration of multiple E/E systems, interaction effects, and vehicle-level testing strategies and test methods during vehicle testing.
• Safety validation: Defines validation environment, test specification, execution and evaluation practices to prove that safety goals are met in the operational context.
• Work products & annexes: Annex A gives an overview of objectives, prerequisites and work products; other annexes provide HARA support and example controllability classification techniques.

Practical applications

• Use ISO 26262-12:2018 to:
  • Tailor functional safety processes for motorcycle design and production.
  • Perform hazard analysis, determine ASILs and specify safety goals for motorcycle E/E systems.
  • Guide vehicle-level integration, testing and validation of safety features (ABS, traction control, rider-assist systems, etc.).
  • Integrate legacy systems or altered production systems into a compliant safety lifecycle.

Who should use this standard

• Motorcycle OEMs and tier‑1/2 suppliers
• Functional safety engineers and system integrators
• Test laboratories and validation teams
• Safety managers and process owners responsible for ISO 26262 compliance
