One crucial aspect of maintaining the effectiveness of ADAS is proper calibration. At Bristol Wheel Alignment, our experienced technicians offer ADAS calibration services to ensure the correct functioning of these systems.


What is ADAS Calibration?


Understanding the concept of ADAS Calibration

ADAS Calibration refers to adjusting and aligning the sensors and cameras of the ADAS system to ensure accurate measurements and reliable functionality. The ADAS system, composed of sensors and cameras, detects potential hazards on the road and assists the driver in avoiding accidents.

These sensors and cameras must be properly calibrated to provide accurate information for timely warnings and correct vehicle responses.

Why is ADAS Calibration necessary?

ADAS Calibration is necessary to ensure the safety system functions optimally and accurately. Misaligned sensors and cameras can lead to incorrect readings, resulting in delayed or inaccurate warnings to the driver.

Consequently, the ADAS system may not perform as intended in critical situations, increasing the risk of collisions and compromising the safety of the driver and other road users.

The importance of proper ADAS Calibration for safety

Proper ADAS Calibration is crucial for enhancing safety on the road. When accurately calibrated sensors and cameras, the ADAS system can provide timely and reliable warnings for potential collisions, lane departures, and other hazards.

This allows the driver to react promptly and take appropriate actions to avoid accidents. Additionally, calibrated ADAS systems can support advanced features like adaptive cruise control and autonomous emergency braking, further improving safety on the road.

Common Problems with ADAS Systems

What are the common issues with ADAS Systems?

ADAS systems can experience various problems, including misalignment, sensor malfunctions, and calibration errors. Misalignment can occur due to factors such as accidental impacts, improper repairs, or general wear and tear.

This can result in inaccurate readings and compromised functionality of the ADAS system.

How does a misaligned ADAS system affect vehicle performance?

A misaligned ADAS system can negatively impact vehicle performance and compromise safety on the road. For example, the lane departure warning system may not provide timely alerts if the sensor is misaligned.

Similarly, the adaptive cruise control feature may not accurately maintain a safe distance from vehicles ahead, increasing the risk of collision. Proper ADAS calibration is essential to ensure these features work accurately and effectively.

Signs that indicate your ADAS system needs repair

If you notice any of the following signs, it may indicate that your ADAS system requires repair or calibration:

  • Malfunctioning or inconsistent warnings
  • Inability to maintain a set speed or distance in adaptive cruise control
  • Unintended activation of emergency braking
  • Faulty blind-spot detection or rearview camera display
  • Frequent system error messages or warnings

Choosing the Right Technician for ADAS Calibration

Qualifications and expertise of an ADAS Calibration technician

An ADAS Calibration technician should have the necessary qualifications and expertise to perform accurate calibrations. They should be knowledgeable about different ADAS systems and their specific calibration requirements.

Additionally, technicians should stay updated with the latest advancements in ADAS technology to ensure they can effectively calibrate newer vehicle models.

The role of an automotive technician in ADAS Calibration

An automotive technician plays a crucial role in ADAS Calibration as they possess the technical skills and experience required for the job. They understand the intricacies of the calibration process and can accurately align the sensors and cameras of the ADAS system.

Their expertise ensures that the ADAS system functions optimally, enhancing both the safety and performance of the vehicle.

Why it is important to choose a certified ADAS Calibration technician

Choosing a certified ADAS Calibration technician is important to ensure that the calibration process meets the required standards. Certified technicians have undergone specialized training and have proven their proficiency in ADAS Calibration.

They possess the necessary knowledge and skills to calibrate various ADAS systems accurately, providing reassurance that your vehicle’s safety features are working effectively.

The equipment required for accurate ADAS Calibration

ADAS Calibration requires specialized equipment to precisely align the sensors and cameras. This equipment includes target boards, calibration targets, and diagnostic tools.

Additionally, advanced calibration systems use computer software to ensure accurate calibration and perform thorough diagnostic checks.

Tips for successful ADAS Calibration

For successful ADAS Calibration, it is important to follow these tips:

  • Choose a certified technician with experience in ADAS Calibration
  • Ensure that the calibration equipment is up-to-date and properly maintained
  • Adhere to the manufacturer’s guidelines for calibration accuracy
  • Regularly inspect and maintain the ADAS system to detect any issues early on
  • Keep the windscreen and sensors clean to prevent interference with calibration

Benefits of Proper ADAS Calibration

Enhanced safety features with accurate ADAS Calibration

Proper ADAS Calibration enhances the effectiveness of safety features, such as forward collision warning and pedestrian detection.

Accurate calibration ensures that these systems can detect potential hazards and provide timely warnings to the driver, helping to prevent accidents and collisions.

Improving vehicle performance through ADAS Calibration

ADAS Calibration also improves overall vehicle performance by ensuring that features like adaptive cruise control and steer assist function accurately.

Proper calibration enables these systems to operate smoothly, resulting in a more comfortable driving experience and better control over the vehicle.

Reducing the risk of collisions with correctly calibrated ADAS systems

Correctly calibrated ADAS systems significantly reduce the risk of collisions on the road.

By providing accurate information and warnings, these systems assist drivers in making informed decisions and taking prompt actions to avoid accidents.

The adequately aligned sensors and cameras prevent false alarms and better facilitate collision avoidance.


What does ADAS mean for Car Maintenance?


ADAS increases vehicle complexity and requires additional maintenance. The systems use radar, sensors, cameras, or a combination, which need calibration after specific work or repairs. Examples of work needing ADAS calibration include:

  • Wheel alignment
  • Suspension work
  • Headlamp alignment
  • Windscreen replacement

It is also vital that whenever ADAS is calibrated, then four-wheel alignment must also be checked and corrected if necessary. If the wheels aren’t aligned correctly, the vehicle will not be travelling where the electronics think it should be, which could cause a fault light or even the system to fail to operate when needed.
