Advanced Driver Assistance Systems (ADAS) are an integral part of modern cars, providing a range of safety features that assist drivers in avoiding accidents. These features are essential for safe driving, and they rely on a range of sensors and cameras to operate effectively. One of the critical components of ADAS is the windshield, which acts as a support structure for the sensors and cameras. Therefore, when the windshield is replaced, it is essential to calibrate the ADAS systems to ensure their proper functioning. In this article, we will explore the process of ADAS calibration with windshield replacement.
What is ADAS Calibration?
ADAS calibration is the process of adjusting and testing the various sensors and cameras in the car’s ADAS systems to ensure their accuracy and proper functioning. ADAS systems rely on a combination of sensors, cameras, and radar systems that work together to provide critical safety features such as lane departure warnings, collision avoidance, and automatic emergency braking. These systems must be calibrated precisely to work correctly.
When is ADAS Calibration Required?
ADAS calibration is required when there is any change to the sensors or cameras, including when the windshield is replaced. Windshields play a crucial role in ADAS systems, as they are typically mounted with sensors and cameras that provide data to the systems. When the windshield is replaced, the sensors and cameras are typically removed and re-installed, which can affect their accuracy and alignment. Calibration ensures that the systems are working correctly after the windshield replacement.
The Importance of ADAS Calibration
ADAS systems are designed to keep drivers and passengers safe on the road. These systems rely on a range of sensors and cameras that work together to provide critical safety features. When these sensors and cameras are not calibrated correctly, they can provide inaccurate or incomplete data, leading to false alarms or, worse, a failure of the ADAS systems when they are needed most. Therefore, it is critical to calibrate the ADAS systems regularly, especially after any changes to the sensors or cameras.
ADAS Calibration with Windshield Replacement
When a windshield is replaced, it is essential to calibrate the ADAS systems to ensure their proper functioning. The following are the steps involved in ADAS calibration with windshield replacement:
Step 1: Pre-Scan
Before the windshield is replaced, a pre-scan is conducted to check the ADAS systems’ operation. This scan provides a baseline for the systems, allowing for any changes to be identified after the windshield is replaced. The pre-scan is typically done using diagnostic equipment that can read the ADAS systems’ data.
Step 2: Windshield Replacement
The old windshield is removed, and the new windshield is installed. During this process, care is taken to ensure that the sensors and cameras are not damaged or misaligned. The windshield is also cleaned thoroughly to ensure that there are no contaminants that could interfere with the sensors’ operation.
Step 3: Post-Scan
After the new windshield is installed, a post-scan is conducted to check the ADAS systems’ operation. This scan checks the sensors and cameras’ alignment and calibration and ensures that they are working correctly. Any discrepancies between the pre-scan and post-scan are identified and addressed.
Step 4: ADAS Calibration
If the post-scan reveals any issues with the ADAS systems’ operation, calibration is required. Calibration involves adjusting the sensors and cameras to ensure that they are aligned correctly and calibrated to provide accurate data. Calibration can be done using specialized diagnostic equipment that can adjust the sensors and cameras’ alignment and calibration settings.
Step 5: Verification
After the calibration is complete, a final verification test is conducted to ensure that the ADAS systems are operating correctly. This test confirms that the sensors and cameras are providing accurate data and that the ADAS systems are working as intended.
