What to Know About Getting Your Car's Windshield Calibrated

A windshield is an essential component of any vehicle. It protects the driver and passengers from wind, debris, and other elements and plays a crucial role in the car's structural integrity. With advancements in technology, windshields have become more than just a piece of glass; they are now equipped with various sensors and cameras that assist in driving assistance systems. However, the windshield needs proper calibration for these systems to function properly. In this guide, we will discuss everything you need to know about getting your car's windshield calibrated.

What Is Windshield Calibration?

Windshield calibration is the process of adjusting and aligning the sensors and cameras on a vehicle's windshield so that they can accurately detect and interpret data. This data is then used by various systems, such as lane departure warning, adaptive cruise control, and automatic emergency braking, to assist the driver in operating the vehicle safely. Without proper calibration, these systems may not work correctly, putting the driver and passengers at risk.

The Basics of Windshield Calibration

In most modern vehicles, windshield calibration is done using cameras and sensors located on the windshield. These cameras and sensors are usually mounted near the rearview mirror or within the vehicle's cabin. They use various technologies such as infrared, laser, or ultrasound to detect objects and provide information to the car's computer system.

Types of Windshield Calibration

Static Calibration

This is done when the vehicle is stationary and no movement is required. It involves positioning a target or pattern in front of the cameras and sensors to ensure they are aligned correctly. This type of calibration is typically used for lane departure warning systems.

Dynamic Calibration

Also known as on-road calibration, this is done while the vehicle is in motion. It involves driving the vehicle at a certain speed and following specific instructions to ensure that the cameras and sensors are accurately calibrated. This type of calibration is usually required for systems such as adaptive cruise control and automatic emergency braking.

The Importance of Calibration for Advanced Driver Assistance Systems (ADAS)

Lane Departure Warning

This system detects when a vehicle is drifting out of its lane and alerts the driver. It does this by using cameras and sensors to monitor lane markings on the road. If the windshield is not properly calibrated, it may affect the system's accuracy, leading to incorrect or delayed warnings.

Adaptive Cruise Control

Adaptive cruise control uses sensors to maintain a safe distance between the vehicle and the one in front of it. This system can also detect when a vehicle suddenly cuts in front, apply brakes if necessary, and resume speed once the road is clear. If the windshield is not calibrated correctly, it may affect the sensors' ability to detect other vehicles accurately, leading to potential collisions.

Automatic Emergency Braking

Automatic emergency braking is a safety feature that can automatically apply the brakes if it detects an imminent collision. It uses sensors to monitor the distance between the vehicle and objects in front of it. If these sensors are not calibrated correctly, they may not provide accurate information, resulting in delayed or failed automatic emergency braking.

Signs that Your Windshield Needs Calibration

Warning Lights

If there is an issue with the sensors or cameras on your windshield, it may trigger warning lights on your dashboard. This could indicate a need for recalibration.

Changes in Driving Assistance Systems' Functionality

If you notice that your lane departure warning, adaptive cruise control, or automatic emergency braking is not functioning properly, it could be due to a misaligned windshield.

Windshield Replacement

If you have recently replaced your windshield, it is crucial to have it calibrated. Even minor changes in the position of the sensors and cameras can affect their accuracy.

Properly calibrated windshields are essential for both safety and legal compliance. If you have ADAS in your vehicle, it is crucial to have your windshield calibrated correctly to ensure the proper functioning of these systems. Always consult a professional technician for windshield calibration and follow recommended maintenance schedules to keep yourself and others safe on the road.
