Steering angle sensors are pretty self-explanatory. They indicate in which direction the steering wheel is turned. Adjusting your steering angle sensor is key to accurate zero point calibration. Some systems calibrate themselves, others require recalibration with a diagnostic tester, and still others require additional procedures.
Typical calibration requirements include setting the wheels straight and using a diagnostic tester to set the steering angle to zero. ADAS calibration requires aligning these sensor devices in your car so that they work properly. A dynamic calibration process requires the technician to take your car for a ride, while a static calibration process uses specialized tools to calibrate the ADAS while your car is stationary. ADAS is a rapidly growing new technology that includes features designed to help drivers drive.
If your driver assistance system is equipped with a safe human-machine interface, it should increase vehicle safety and road safety in general. Dynamic calibration requires the vehicle to be driven at specific speeds and conditions while connected to an ADAS reader, but that is anything but a test drive. ADAS calibration (and recalibration) is the precise physical alignment, testing, and electronic alignment of sensors that collect data to inform your vehicle’s advanced driver assistance systems (ADAS), such as Collision Warning (FCW), Lane Departure Warning (LDW), Automatic Emergency Braking (AEB), and many others. To help you understand, here are some of the most common ADAS sensors that need to be calibrated most frequently.
ADAS features became increasingly popular in the early 2000s, with most recent models incorporating ADAS into their original designs. For example, vehicles with a windshield-mounted front ADAS camera must be calibrated after the windshield has been replaced. However, the final adjustments are made during calibration and are carried out electronically by the ADAS module itself. STATIC ADAS calibration uses specialized tools in a specially rendered environment to precisely adjust sensor angles.
Automotive professionals must know and comply with OEM ADAS calibration standards in order for a vehicle’s ADAS systems to function properly. Unfortunately, not all ADAS sensors have self-diagnosis features to tell the driver when the calibration is over.
