New modern cars are built with systems that improve car owners’ safety while driving. These systems, known as “Advanced Driver Assistance Systems,” collect data from the vehicle’s surroundings. However, this system can only function based on the information that is fed into it; thus, ADAS calibration is required. In this article, we will go over everything you need to know about ADAS calibration.
What is ADAS Calibration
ADAS Calibration is the process of physically aligning the sensors in a vehicle’s ADAS system, which is in charge of gathering information from the vehicle’s environment in order to provide vital signals and warnings to the driver, such as Forward Collision Warning (FCW) and Automatic Emergency Braking (AEB), among others.
What are some ADAS sensors to calibrate?
Sensors in new cars are usually precalibrated and properly positioned. They may, however, become out of place over time or as a result of an accident or minor fender bender. Not all ADAS sensors in the car, such as the sonar or ultrasonic parking sensor located in the bumper, would require calibration. However, if the bumper is damaged in an accident, the ultrasonic sensors must be replaced. Among the sensors that should be calibrated are the following:
- Steering Angle Sensor: The steering angle sensors detect which way the steering wheel is being turned. This procedure entails straightening the steering and wheels and zeroing out the steering angle with a scan tool. Blind spot detection, lane keeping assist, lane departure assist, and adaptive headlights all benefit from steering angle sensors.
- Forward Radar Sensors: These sensors are typically located in the car’s front bumper or grille and are in charge of detecting the distance of objects in front of the car as well as guiding the following distance. The Forward Radar Sensors provide data for Adaptive Cruise Control, Automatic Emergency Braking, and Forward Collision Warning.
- Rear Radar Sensors: These sensors are located at the car’s rear corners, just after the bumper cover. These short-range sensors are in charge of detecting the distance of approaching objects from the rear and sides of the vehicle. The rear radar sensors collect data for rear cross-traffic alerts, automatic emergency braking, and blind spot warning.
- Front-facing camera sensors: These sensors are typically located in the windshield of a car, next to the rearview mirror, and function to detect objects or obstructions such as cars and people in your vehicle’s forward view. These sensors measure the distance between the car and objects in front of it, as well as road markings, traffic signs, and light levels. The information provided by the front-facing camera sensors is used for automatic emergency braking, lane departure warning, adaptive cruise control, lane keeping assist, and automatic high beams.
Types of ADAS Calibration
Dynamic ADAS Calibration and Static ADAS Calibration are the two types of ADAS Calibration. The type of ADAS calibration required depends on the ADAS system in the vehicle; some require dynamic calibration, others static calibration, and still others both.
Dynamic ADAS Calibration
Dynamic ADAS calibration is similar to an advanced test drive in that it involves driving the car at a specific speed while connected to a scan tool. This type of calibration requires two people: one to drive and the other to operate the scan tool. Several tests are performed on the vehicle, including driving on marked roads, driving alongside other vehicles, and driving at a specified speed. The procedure for dynamic calibration, on the other hand, varies by manufacturer.
Static ADAS Calibration
The vehicle is kept static in a controlled environment with level ground, uniformly painted walls, and uniform and adjustable lighting for static ADAS calibration. It is also ensured that there are no obstacles or clutter around the vehicle, as well as that there are no reflective surfaces or direct sunlight in the space. The size of the environment should be at least 30′ by 50′.
To ensure that sensor angles are precisely aimed, technicians use specialized tools such as a scan tool, an ADAS calibration tool, a measuring tape, an ADAS alignment rack, and aiming targets. It should be noted that some vehicle models would necessitate manual adjustment for some censors. For vehicles that require both ADAS calibration procedures, static calibration is usually the first stage.
Why is ADAS Calibration important?
The number of cars equipped with ADAS is rapidly increasing, as is the number of repair shops offering ADAS calibration services. To ensure that the inbuilt sensors remain in their original position and function properly, ADAS calibration is required.
These sensors aid in the safety of drivers and other road users. For example, properly calibrated sensors can accurately measure the distance of objects from the vehicle and assist the driver in determining a safe braking distance. It also aids in the detection of blind spots and obstructions that the driver may overlook.
Overall, the ADAS system improves road safety for both drivers and pedestrians. Vehicle owners should take their vehicles in for ADAS recalibration if the windshield or bumpers are damaged, as these are the primary locations for ADAS sensors.
How much does it cost to calibrate a car?
The cost of calibrating a car varies depending on the car’s OEM specifications and the location of the calibration. Different car models necessitate distinct calibration procedures. ADAS calibrations can cost up to $1200 or more, depending on the vehicle and the method used.
Does insurance cover ADAS Calibration?
Most ADAS calibrations are covered by insurance companies if the vehicle owner has a full coverage policy. If your insurance policy covers broken windshields or other vehicle damage, that could interfere with the Advanced Driver Assistance Systems.
Any car body shop can perform your ADAS Calibration. However, you should ensure that the technician has all of the necessary calibration equipment and tools.
