The Challenge

  • Development of a redundant braking system for an autonomously driving truck (SAE L4)
  • Poorly documented primary braking system, from which much should be taken over

The Approach

  • Analysis of safety documents
  • Rework of the Item Definition
  • Derivation of FTTI of safety goals
  • Fault Tree Analysis (FTA)
  • Functional Safety Requirements derived from the FTA

Result & Added Value

  • Support in the preparation of the safety documentation required for QG30
  • Description of the system and its functions with the Item Definition (ID)
  • Theoretical and practical derivation of the FTTI for the safety objectives
  • Qualitative FTA based on the safety goals
  • Important and basic functional safety requirements
  • Description of the system and its functions (ID and HAZOP)
