What are ADAS calibrations?
ADAS calibration involves precisely aligning, testing, and electronically aiming sensors that collect data for your vehicle’s advanced driver assistance systems (ADAS). It ensures these safety systems function accurately after repairs or maintenance.
What Does ADAS Stand For?
ADAS stands for Advanced Driver Assistance Systems. These systems use sensors to enhance driver safety by providing warnings and even taking temporary control over braking or steering.
Why Is ADAS Calibration Necessary?
After vehicle damage or repair, ADAS systems must be recalibrated to their pre-accident condition. Proper calibration ensures accurate sensor performance.
Which Sensors Require Calibration?
Common examples of sensors needing calibration include:
- Forward Collision Warning (FCW)
- Lane Departure Warning (LDW)
- Automatic Emergency Braking (AEB)
What Happens if Sensors Are Misaligned?
Even a slight misalignment can significantly affect sensor accuracy. For instance, a sensor off by a fraction of an inch could be aimed far off-axis down the road.
When Is Calibration Needed?
Calibration is necessary after:
- Collisions
- Windshield Replacement (for forward ADAS cameras)
- Minor repairs or parts replacement
Do Sensors Self-Diagnose Calibration Issues?
Unfortunately, most ADAS sensors lack self-diagnostic capabilities. Automotive professionals must follow OEM standards for calibration.
What Types of Calibration Exist?
- Static Calibration: Performed in a controlled environment.
- Dynamic Calibration: Done during real-world driving.
