Modern vehicles are equipped with Advanced Driver Assistance Systems (ADAS) that enhance safety and driving efficiency. Many of these systems rely on forward-facing cameras mounted to the windshield, which require precise calibration after a windshield replacement. Ensuring proper calibration is crucial for maintaining the functionality of systems such as Lane Keep Assist (LKAS), Lane Departure Warning System (LDWS), Forward Collision Alert (FCA), and others.
Why Windshield Camera Calibration Is Necessary
When a windshield is replaced, even a slight misalignment of the ADAS camera can cause incorrect system responses. Improper calibration can lead to malfunctioning safety features, increasing the risk of accidents. Calibration ensures the vehicle’s safety systems function as intended by the manufacturer.
Types of Windshield Camera Calibration
There are two primary types of windshield camera calibration:
- Static Calibration
- Performed in a controlled environment, such as an auto glass shop.
- Requires specialized calibration targets placed at specific distances.
- The vehicle remains stationary while the system is adjusted.
- Dynamic Calibration
- Requires the vehicle to be driven on well-marked roads at a predetermined speed.
- The vehicle’s system uses real-world data to recalibrate the camera.
- This method is typically required by certain manufacturers.
Some vehicles may require both static and dynamic calibration to ensure accuracy.
ADAS Features That Require Calibration
Several safety features depend on correctly calibrated cameras, including:
- Lane Keep Assist (LKAS): Helps keep the vehicle centered in its lane by making small steering adjustments.
- Lane Departure Warning System (LDWS): Alerts the driver if the vehicle drifts out of its lane without signaling.
- Forward Collision Alert (FCA): Warns the driver of potential frontal collisions and may engage automatic braking.
- Adaptive Cruise Control (ACC): Adjusts the vehicle’s speed based on the distance to the car ahead.
- Traffic Sign Recognition (TSR): Identifies and displays road signs on the dashboard.
When Is Windshield Camera Calibration Required?
Calibration is necessary in the following situations:
- After a windshield replacement.
- Following an ADAS-related fault code or dashboard warning.
- If the camera has been disconnected or replaced.
- After wheel alignment or suspension modifications that could affect camera angles.
- If the vehicle has been involved in a collision, even if the windshield wasn’t directly impacted.
The Calibration Process
- Pre-Calibration Inspection: A technician checks for any damage to the camera or windshield mounting.
- Calibration Setup: Depending on the vehicle, static, dynamic, or both methods may be used.
- System Verification: The technician tests ADAS functionality post-calibration to ensure accuracy.
- Final Inspection: The vehicle is checked for proper camera alignment before being returned to the customer.
Choosing the Right Auto Glass Shop for ADAS Calibration
Not all auto glass shops have the equipment and expertise for ADAS calibration. When selecting a service provider, consider:
- Whether they use OEM-approved calibration tools.
- If they offer both static and dynamic calibration.
- Their experience with your vehicle’s make and model.
- Whether they provide a post-calibration report verifying system accuracy.
