Phase 4: after an accident

To reduce consequential damage after an accident and support the work of the rescue services, a number of different actions are initiated, depending on the type and severity of the accident:

  • Better protection: the engine can be switched off automatically and the fuel supply can be cut off.
  • Conspicuous lighting: the hazard warning lamps and the emergency interior lighting can be activated automatically in order to prevent consequential accidents and make it easier to find the accident vehicle.
  • Good escape possibilities: the doors can be automatically unlocked.
  • Measure to aid rescue: integral crash joints between the wing and the door can make opening the doors after a frontal collision easier.
