What is adas?

Advanced Driver Assistance Systems (ADAS) are systems developed to automate/adapt/enhance vehicle systems for safety and better driving. Safety features are designed to avoid collisions and accidents by offering technologies that alert the driver to potential problems, or to avoid collisions by implementing safeguards and taking over control of the vehicle. Adaptive features may automate lighting, provide adaptive cruise control, automate braking, incorporate GPS/ traffic warnings, connect to smartphones, alert driver to other cars or dangers, keep the driver in the correct lane, or show what is in blind spots.

New ADAS Technologies

New ADAS technologies that are being intergrated into all vehicle types.

  • Traffic assistant
  • Adaptive Cruise Control (ACC)
  • Lane keep assist, Lane departure warning
  • Electro-mechanical steering
  • Parking assist or park help
  • Reverse assist, all round vision camera system
  • Night vision assist
  • Adaptive lighting systems
  • Traffic sign recognition
  • LiDAR – Volvo City Safe
  • Position Acquisition Local Mapping

Front Camera Calibration

Like other sensors for ADAS [Advanced Driver Assistance Systems], video cameras collect information far ahead of the car. Those high tech sensors need to be accurately aligned parallel to the geometrical axis of the vehicle. If the windshield position differs just slightly after it was replaced, the viewing angle of the camera is likely to be incorrect. Since the camera clips cannot be adjusted, any deviation must be compensated by the ECU if the ADAS is to function correctly.

What do they do?
  • Road-Sign Recognition
  • Speed Limits
  • Overtaking prohibition
  • Lane Departure
  • Glare-Free High Beam
  • Camera sees cars driving ahead
  • Recognises oncoming traffic
Effects by incorrect calibration
  • Warning lights on in the dashboard or message
  • Incorrect function
  • Deactivation of the system
  • Deactivation of corresponding ADAS-Systems
  • Incorrect operation due to wrong values
When Do I need recalibration?
  • Faulty Camera
  • Faulty ECU
  • After a windshield replacement
  • After a wheel alignment geometry adjustment
  • After a mechanical repair affecting geometry
  • Following a bodyshop/crash repair
