ADAS (Advanced Driver Assistance Systems) are passive and active safety systems designed to remove the human error component when operating vehicles of many types. ADAS systems use advanced technologies to assist the driver during driving, and thereby improve drivers' performance.
ADAS uses a combination of sensor technologies to perceive the world around the vehicle, and then either provide information to the driver or takes action when necessary.
Almost all vehicle accidents are caused by human error, which can be avoided with Advanced Driver Assistance Systems (ADAS). The role of ADAS is to prevent deaths and injuries by reducing the number of car accidents and the serious impact of those that cannot be avoided.
When a windshield is replaced, the ADAS-related equipment (like cameras and sensors) is removed and then re-attached. A change of just one degree in a camera angle can have a large impact on the vehicle's viewing area.
This is one reason why we calibrate windshields. It will affect how the car's ADAS features work and the overall safety of the vehicle.
The calibration process will adjust and test all of the cameras and sensors on the windshield. This is to ensure everything is functioning properly after the windshield has been replaced. Without calibration, the ADAS features can malfunction, which can result in an accident.
