Why ADAS Calibration Is Important

If you’ve bought a newer-model car in the past few years, you’ve surely noticed all of the bells and whistles that now come standard. Backup cameras, adaptive cruise control, lane assistance: these ADAS features are a game-changer—when they’re calibrated correctly.

Today, we’re discussing why ADAS calibration is so important. Keep reading to learn what ADAS is, exactly, and why you need to keep it calibrated.

What Is ADAS?

ADAS, or “advanced driver assistance system,” is a type of system that improves your ability to operate your vehicle safely and effectively.

We mentioned a few types of ADAS above, but there are many more features available in vehicles today:

  • Backup cameras
  • Cruise control (adaptive or non-adaptive)
  • Forward collision warnings
  • Lane departure warnings
  • Lane change assistance
  • Traction control
  • ABS brakes
  • Automatic parking
  • Collision avoidance
  • Tire pressure monitoring
  • Automatic headlights (high beams and dimming)
  • Blind spot monitors
  • Pedestrian detection

The list goes on!

These features assist the driver, with various levels of control. While some ADAS features just give the driver more information—like blind spot monitors—other features, like automatic parking, control the car for the driver. Essentially, ADAS is designed to help remove some of the “human error” from driving.

ADAS works by using sensors placed at various points on the car. ADAS sensors are generally located on the front and rear bumpers, front windshield, front grill, side mirrors, and rear view mirror.

These sensors use multiple data sources, like automotive imaging, LiDAR, radar, image processing, computer vision, and in-vehicle networking. ADAS sensors alert the driver using vibration, sound, and flashing warnings. More complex ADAS, like lane assistance, uses cameras to monitor lane markings and takes control of the steering wheel.

When properly calibrated, ADAS is an amazing tool to help keep you safe on the road. But what if it’s not calibrated?

Why Is ADAS Calibration Important?

ADAS calibration involves the physical alignment, testing, and electronic aiming of the sensors. In order to work properly, ADAS sensors need to be aimed very precisely.

Consider this: AAA reports that a sensor out of alignment by less than an inch, or even just one degree, will be significantly misaligned 50 feet or more down the road. What does that mean for you, the driver?

It means that your ADAS features won’t work properly or at all—which is disastrous when you rely on them to help you avoid a crash.

For example, uncalibrated ADAS systems might result in the following:

  • Warning signals coming too late or not at all
  • Increased effort to use the steering wheel
  • Steering too soon or too late
  • Braking too late or not at all
  • Missed hazards in the road or in blind spots
  • Incorrect lane assistance, like drifting out of your lane

At worst, improperly calibrated ADAS can contribute to a crash! That’s why ADAS calibration is so important: it ensures that your car’s safety features are in tip-top shape.

Because ADAS sensors are sensitive, you need to calibrate them in the following situations:

  • When the ADAS lights are on or blinking, indicating a problem with the system
  • When your windshield is repaired or replaced
  • When you get into an accident (even if it’s a minor fender bender)
  • When your car gets side-swiped or someone knocks your mirror off
  • When your car gets body repairs like wheel alignment, tire rotation, or replacing your tires with a change in ride height

When you are getting your car repaired or your windshield fixed, make sure that the auto shop can handle ADAS calibration. The technicians working on your car should be experienced and using top calibration tools. (After all, your life might be in their hands!) Here at Jack’s Glass, for example, our pro technicians use the two best windshield camera calibration tools available on the market: Opti-Aim and Autel’s MaxiSys ADAS. We provide calibration accuracy to the millimeter!
