Test Setup: Instrument Cluster Elements


Instrument cluster elements have to be security-critical and display legally required notifications reliably in all languages. The task was the design of an automation process to test actually displayed graphic elements.


  • Automated test stand for different ECUs
  • Installation of mechanical test setup
  • Automatically generate more than 100 different information and warning notifications
  • Image capture with frame grabber and cameras
    • Instrument cluster
    • Central display (for further information)
  • Image recognition with OCR algorithms for
    • Over 40 languages, including Asian and Arabic characters
    • Icons of warning notifications
  • Capture of signal tones by audio analysis


Extraordinary reduced test effort in parallel to fully systematic coverage, documentation, and replicability of all warning messages.
