An ADAS alignment is a calibration of the components in an Advanced Driver Assistance System.
Vehicles equipped with ADAS rely on special sensors, cameras, and radar units that are mounted on the body that are able to detect lane markings, road features, and obstacles. Data from these sensors, along with that from steering and suspension sensors, help to enhance the driving experience and improve vehicle safety. ADAS attempts to do so by performing driver tasks, such as automated parallel parking, adaptive cruise control. It also might activate safety features, such as lane departure warnings, emergency braking, or pedestrian avoidance.
In order for these features of ADAS to work correctly, all of the sensors and electronics associated with the ADAS system must be calibrated and aligned correctly. Because the ADAS system can take control of your brake or steering systems during activation, all of the sensors and cameras must be set properly. For example, if a camera is not aligned as it should be, some features might not activate when needed - or they might cause more harm than good.
Not all vehicles come equipped with ADAS, although it is becoming more popular on passenger vehicles. Modern ADAS incorporates a variety of sensors, cameras, and radar units. When they are functioning properly, ADAS can be a valuable tool to provide drivers with potentially life-saving maneuvers and other services. When working incorrectly, on the other hand, the system can either not function at all, or might actually be counterproductive. Examples of problems that indicate an inspection and alignment of your ADAS include:
The specific procedures a technician would follow for an ADAS alignment will differ somewhat from one vehicle make and model to the next. A general set of steps a technician would take include:
