What is ADAS
ADVANCED DRIVERS ASSISTANCE SYSTEMS
Many manufactures started to offer advance drivers assistance systems options as early as 2005. The systems include automatic braking, lane keep assist, collision avoidance, adaptive cruise control, blindspot sensors, and other systems that can intervene or help the driver when potential dangers are detected.
These systems use cameras, lasers and radar to detect other vehicles, pedestrians and markings in the road. But the vehicle needs to be accurately aligned for these systems to work. If a radar sensor is moved from its mounting during a repair or in a rear end collision it must be recalibrated using the manufactures procedures.
There are two ways for a a ADAS system to be calibrated. One method involves using targets mounted to a fixture at precise distances from the sensor. The recalibration process is initialized with a scan tool. The other method is a self learn test drive that is also initiated with the help of a scan tool. In some cases it might take several hours and multiple test drives for the system to be calibrated this is often the case if the system has blindspot sensors.
