What is an Advanced Driver Assistance System (ADAS)?
ADAS stands for “Advanced Driver(s) Assistance Systems”. These systems rely upon cameras, lasers, and radar – often with the camera mounting to the windshield. ADAS sensor calibration is required whenever a sensor’s aiming is disturbed in any way. This can occur in a collision, even a minor fender bender, or be a byproduct of common service work such as windshield replacement, suspension repairs or wheel alignment.
Any time a new windshield is installed, the camera must be calibrated to ensure proper functionality and to restore the camera to OEM specifications.
Examples of ADAS applications are:
- Lane Departure Warning
- Forward Collision Alert
- Collision Mitigation Braking System
- Traffic Sign Recognition
- Blind Spot Monitoring
- Park Assist
- Adaptive Cruise Control
- Pedestrian Detection
- Headlights Control
- Lane Keep assist
- Driver Status Monitoring (DSM)
What Is ADAS Calibration?
Calibration is the process of returning a vehicle’s ADAS to OEM specifications Calibration is necessary after installation of a new windshield with a camera mounted to it, to ensure that the ADAS features continue to function properly after having been moved during installation.
What will happen if your ADAS is not properly calibrated??
If a car’s ADAS is not properly calibrated, the system may not function safely. If the cameras/radars/lasers on the vehicle are off by even a few millimeters they may not give accurate readings and the system may not function properly.
A misaligned camera could jeopardize the functionality of the system and lead to dangerous driving or accidents, so it is crucial that the cameras are aligned perfectly, which is what windshield calibration ensures.
Types of Windshield Camera Calibration:
Requires driving the vehicle at a set speed on well-marked roads for a specific amount of time to recalibrate the camera system. Typically takes up to one hour or more, depending on the make and model of the vehicle.
Requires manufacture specific target images mounted on a fixture in front of the vehicle during the recalibration process. Typically takes one hour or more, depending on the make and model of the vehicle.
