Understanding ADAS Calibration Methods

In the ever-evolving landscape of automotive technology, few technologies are as pivotal to vehicle safety and functionality as Advanced Driver-Assistance Systems (ADAS). In a 2019 survey, 57 percent reported that at least one ADAS feature helped avoid a crash.

ADAS rely on sensors and cameras to monitor your vehicle’s surroundings, provide data to assist the driver by taking action to prevent collisions. As a result, system calibration is crucial to the functionality of safety systems such as adaptive cruise control, lane-keeping assist, and many others.

Read on to understand the necessity behind ADAS calibration and its methods.

What is ADAS Calibration?

ADAS Calibration is the method by which technicians calibrate various system components — one of these critical components, such as safety sensors and cameras are mounted on or located inside the windshield — to ensure that all systems of the vehicle operate with the utmost accuracy and perfect alignment. Proper calibration enables the functionality and reliability of all safety and driver-assistive features, which are vital to helping prevent accidents.

The Importance of ADAS Calibration

ADAS calibration after windshield replacement is a matter of safety for drivers and their passengers. These components have an unobstructed line of sight and are positioned to provide accurate and comprehensive data. This is why our windshield ADAS calibration technicians come highly recommended.

Understanding ADAS Calibration Methods

ADAS Calibration Methods

There are three general types of ADAS calibration methods. Static Calibration Dynamic Calibration Combination (Both static and dynamic)

Static Calibration

Static calibrations require special scan tools and targets that are used in a controlled environment while the vehicle is stationary. The calibration environment must meet several requirements, such as:

  • It must be a controlled environment in compliance with OE guidelines.
  • The floor must be level.
  • Surroundings around the vehicle must be un- obstructed.
  • Lighting must be uniform.
  • Area around the vehicle needs to offer no interference with camera view or projection.

Static ADAS calibration tools include:

  • Proper vehicle scan tool
  • OE approved targets
  • Proper measuring equipment

Static ADAS calibration is often the first, if not the only, calibration performed after a windshield or ADAS component replacement since it sets the baseline for the system’s accuracy. When applicable, technicians may also need to perform a dynamic calibration after a static calibration session.

Dynamic Calibration

Dynamic calibration involves calibrating ADAS components while the vehicle is in motion. The calibration environment mimics the conditions under which the systems are designed to operate. Some of these conditions include:

    • Driving at designated speeds.
    • Following a vehicle.
      • Specific number of vehicles
    • Driving on clearly marked roads.
      • [h3] ADAS Components

Advanced Driver-Assistance Systems are complex and comprised of several sophisticated components located throughout the vehicle. Driver assistance features require real-time data to account for varying road conditions and to determine how best to assist the driver. Some ADAS components include:

      • Steering Angle Sensors
      • Front-Facing Camera Sensors
      • Forward Radar Sensors
      • Rear Radar Sensors

How Long Does ADAS Calibration Take?

ADAS calibration is dependent on numerous factors, including a vehicle’s year, make and model and weather conditions. See additional factors below:

  • The number of components to calibrate
  • Vehicle manufacturer complexity associated with the ADAS calibration needed
  • Availability of well-marked roadway
  • Vehicle condition
  • Rain or snow

When an ADAS-equipped windshield is replaced in an ADAS equipped vehicle, a calibration needs to occur at the time of windshield replacement.

The Cost of ADAS Calibration

If you’re going to pay out of pocket for your vehicle’s windshield replacement ensure that the cost of the calibration is included in the price. Fortunately, many full-coverage insurance plans cover the replacement and calibration of your windshield. Additionally, Caliber Auto Glass works with major insurance companies across the nation.

Final Words

ADAS components are crucial to vehicle safety because they gather the real-time data required by your vehicle’s safety systems to function correctly. Proper calibration helps ensure that your safety and driver-assistive systems work when you need them most.

As with all things related to safety, it’s always best to work with reputable professionals with the training, expertise, and equipment to properly perform calibrations.
