Existing type approval

  • network of electronic controlled:
      • steering systems
      • propulsion systems
      • brake systems
      • anti-theft systems
      • restraint systems

intention

  • Increasing rate of CEVCS influencing vehicle’s control
      • autonomous cruise control
      • autonomous park assistance
      • lane keeping assistance
      • enhanced stability control
      • active pre-crash system
    • suitable type approval ?

Systems not covered by type approval

3 Type Approvals

One change within safety concept leads to

  • one amended Type Approval and
  • forces two additional Type Approvals

ECE-R xxx CEVCS

  • this approach
      • assesses the vehicle safety system for CEVCS
      • avoids multiple assessments
      • keeps CEL annexes (ECE-R 13, 13H, 79, …) to reduce type approval efforts for single systems
      • is based on voluntary usage
      • addresses system related approval (different vehicles, models or manufacturers)
