Welcome to Schmidt Auto Care | Springboro, OH

Dings, bumps, and fender benders are an everyday aspect of modern vehicle ownership, even for careful drivers. Unfortunately, the electronic sensors inherent in today’s cars make even simple repairs surprisingly difficult. Advanced driver assistance systems, also known as ADAS, rely on many different cameras and sensors placed throughout the vehicle. While many of these systems are critical for driver safety, the sensors that make their work possible can get out of alignment during collisions or after vehicle service.

The process of realigning these cameras and sensors so they function properly is known as ADAS calibration. ADAS calibration is a critical component of modern vehicle repair, as it ensures that the key safety systems in a car function correctly after a collision. But how do ADAS calibration methods work, and what should you know before getting your car’s ADAS cameras and sensors calibrated?

What is ADAS?

Cars today are increasingly described as computers on wheels, full of innovative systems designed to make driving safer and easier than ever. Advanced driver assistance systems run from simple notifications such as lane departure warnings to features such as active cruise control or park assist. While many systems primarily warn drivers of danger, some of these advanced features can exert control over the vehicle in particular situations.

These systems save lives. The Insurance Institute for Highway Safety has collected large volumes of evidence that the risk of crashing, injury, or death on the roads is reduced when these systems are operational. In fact, since 2020, vehicles seeking a five-star safety rating must have at least one ADAS technology included.

Most ADAS sensors come in three types. Cameras are important for features such as automatic high beam and lane-keeping assist. Radar sensors are used for adaptive cruise control and forward collision warning systems. Ultrasonic sensors are used for pedestrian detection and park assist systems, as they utilize a high-frequency sound wave which is better at detecting smaller objects than the large radio waves used in radar sensors. While these sensors are properly calibrated when the car leaves the factory, they must be readjusted any time they are shifted out of position, as a small amount of misalignment could seriously degrade sensor performance.

Which Vehicle Systems Are ADAS?

ADAS is a broad category covering many different systems. Generally, they all use sensors and cameras to collect data which is processed by the vehicle to provide a precise picture of its surroundings. This information is used to identify potential hazards in the local environment and indicate them to the driver. While all of these systems monitor some aspects of the vehicle’s surroundings, some can actually respond when hazards are identified.

Common ADAS technologies available on many modern cars and SUVs include the following:

  1. Lane Departure Warning Systems: A vehicle’s lane departure system uses both front-facing camera sensors and steering angle sensors to help identify when a car is drifting out of its lane without indicating a lane shift. The forward-facing cameras can identify lane markings in the road ahead, while the steering angle sensors measure the degree of steering wheel rotation to anticipate the vehicle’s future path. More advanced versions offer lane-keeping assist, which can help nudge the car back into its lane if it drifts too far over.
  2. Automatic Emergency Braking: The modern road is a hectic place, with lots of happenings going on right around the driver. Driving requires intense focus and concentration, with the costs of a momentary lapse extremely high. Automatic emergency braking uses forward radar sensors and a front-facing camera to provide the vehicle with a precise estimation of the distance between it and potential hazards in front. If the car appears to be approaching too fast, the automatic emergency braking system can take control and apply the brakes to slow the vehicle and mitigate the damage of an ensuing collision. The accuracy of this system is imperative to avoid both false brake applications and failure to mitigate collisions.

One crucial aspect of ADAS technologies to keep in mind is that they do NOT provide autonomous driving capabilities. It is true that ADAS can steer the car, apply the brakes, and even measure the distance between two objects. However, these are short-term interventions only applicable in particular situations. While features such as adaptive cruise control and active park assist can appear to handle many tasks at once, these are not a substitute for proper driver focus and concentration.

What is the ADAS Calibration Process?

As with many modern, advanced safety devices, ADAS components must be carefully calibrated in order to ensure their proper functioning. There are two types of ADAS calibration processes, static calibration and dynamic calibration. Each ADAS sensor has its own calibration requirements which determine whether static calibration or dynamic calibration is the better option.

Proper ADAS calibration must be done by trained technicians with experience in ADAS recalibration services and knowledge of the specific calibration requirements provided by the vehicle manufacturer. Different carmakers have varying calibration procedures, which must be performed exactly to manufacturer specifications.

Calibration Equipment

ADAS calibration requires specific calibration equipment. The most important of these special tools are an ADAS scan tool and an alignment rack equipped with target patterns. Scan tools can be bought from the automaker or aftermarket. ADAS target patterns are often purchased or downloaded from the manufacturer.

ADAS static calibration procedures must be conducted in a controlled environment with a level surface. Static calibrations are usually performed in a large interior space, such as a room with a flat floor and neutral-colored walls. During static calibration, targets are positioned at different locations around the vehicle. Camera sensors use black-and-white patterned targets, while radar sensors use special metal radar targets to understand how to make adjustments to their positioning. The sensors identify and adjust to their designated aiming points on the targets with guidance from the scan tool. Once the scan tool works through the process and the sensors automatically recalibrate, calibration techs will often run a verification to ensure the ADAS calibration is successful.

Some ADAS sensors, such as those used with lane departure warning systems, must be calibrated when the vehicle is in motion. Though the dynamic calibration process is longer than static ADAS calibrations, it is also more accurate. In fact, many vehicle manufacturers require ADAS sensors to undergo both a static and a dynamic calibration process.

Dynamic ADAS calibration requires driving the vehicle on a particular route under certain specified conditions. Requirements can vary but often involve driving the car on a level road or around a curve at designated speeds. As snow and rain can make dynamic ADAS calibrations difficult or impossible, it is normally not recommended to attempt these procedures in rough weather conditions.

How Else do I Keep My ADAS Sensors Working Properly?

Post-collision repair appointments are not the only time to calibrate ADAS sensors. Work such as alignment, suspension repair, and wheel replacement can shift the angle of the sensor relative to the ground and require calibration. Sensors are carefully built to work in a particular orientation, and misalignment of even one degree will dramatically reduce their effectiveness. In fact, any time ADAS sensors or the sensor bracket housing them change position, calibration is required.

Drivers should also be mindful when replacing parts such as the windshield or the front bumper. ADAS cameras are optimized for a particular windshield glass composition, while radar sensors are designed to work through a certain bumper material and thickness. Thus, when replacing parts covering ADAS cameras or sensors, it is important the replacements are built to the same specifications as the originals.
