How Does Windshield Calibration Work and Why is it Essential

At Keffer Auto Glass in Charlotte, NC, we prioritize your safety by offering windshield calibration services that meet manufacturer specifications. But how does windshield calibration work and why is it essential? Here’s everything you need to know.

Imagine replacing your car’s windshield, only to find that your vehicle feels slightly off when you drive. Modern vehicles are equipped with Advanced Driver Assistance Systems (ADAS) like lane departure warnings, adaptive cruise control, and automatic emergency braking. These critical safety systems often rely on cameras and sensors fitted to your car’s windshield. Improper calibration after a windshield replacement can cause these systems to malfunction and compromise your safety.

What Is Windshield Calibration?

Windshield calibration is the process of adjusting the ADAS components attached to or embedded within your car’s windshield. After a windshield repair or replacement, these systems, such as cameras and sensors, can become misaligned. Windshield calibration ensures that safety systems like automatic braking, forward-collision warning, and lane-keeping assistance function accurately.

For instance, if the forward-facing camera on your car’s windshield isn’t properly calibrated, it may not correctly detect lane markings, causing lane departure warnings to fail. This highlights the critical role proper windshield calibration plays in maintaining vehicle safety.

The Two Types of Windshield Calibration

Windshield calibration generally falls into two categories:

1. Static Calibration

Static calibration involves specific conditions where the vehicle is stationary. A trained Keffer Auto Glass technician uses calibration equipment like target boards or special screens that ADAS cameras and sensors recognize. This process ensures the car’s safety systems are aligned according to the vehicle manufacturer’s specifications.

2. Dynamic Calibration

This involves driving the vehicle on the road to recalibrate ADAS systems. During this process, expert technicians use specialized diagnostic tools to monitor and adjust safety systems while the vehicle operates under real-world conditions. Dynamic recalibration often factors in lane markings, speed, and other environmental elements.

Each type of calibration depends on the car’s model, the ADAS components involved, and manufacturer recommendations.

Why Is Windshield Calibration Important?

Skipping windshield calibration after a replacement or repair can have serious consequences. Here’s why you shouldn’t take this process lightly:

1. Safety First

ADAS systems significantly enhance your car’s safety features. Misalignment of cameras or sensors can lead to incorrect function or complete failure of these systems. For example, inaccurate calibration can prevent automatic emergency braking from activating in time, increasing the risk of accidents.

2. Precision Matters

ADAS features like lane departure warnings and lane-keeping assistance require precision. A slight misalignment of just a few millimeters can cause the system to misread lane markings or give false alerts.

3. Compliance with Manufacturer Specifications

Modern vehicles come with complex systems that require strict adherence to the vehicle manufacturer’s calibration standards. At Keffer Auto Glass, our trained technicians strictly follow these specifications for proper windshield calibration.

Improper calibration can lead to accidents, costly repairs, increased insurance premiums, or even legal liabilities. Working with professional technicians ensures peace of mind and compliance with safety standards.

When Do You Need Windshield Calibration?

You will likely need windshield calibration services in the following scenarios:

  • After a windshield replacement
  • When your car’s windshield ADAS cameras or sensors have been moved or disturbed
  • If your car has experienced a collision affecting windscreen alignment
  • If warning lights or errors related to ADAS appear on your dashboard

How Does Windshield Calibration Work?

The process involves several stages to ensure your vehicle’s safety systems work seamlessly:

  1. Pre-Scan: Before the calibration process begins, a pre-scan is conducted to determine which ADAS systems need to be calibrated and in what way.
  2. Inspection
  3. Adjusting Camera Alignment: Cameras are adjusted according to manufacturer specifications using specialized tools.
  4. Target Placement: Targets are placed on specific areas of the vehicle, such as the wheels and steering wheel, to provide a reference point for the calibration process.
  5. Calibration Procedure Execution: The actual calibration procedure varies depending on the make and model of your vehicle, but generally involves driving at certain speeds and making turns while cameras capture data for adjustment.
  6. Post-Scan: After calibration is completed, a post-scan is performed to ensure all systems are functioning properly and the ADAS features are operating correctly.

Additional Considerations for ADAS Calibration

As technology continues to advance, so will the complexity of ADAS systems. To ensure proper calibration, it’s important to keep in mind the following considerations:

  • Regular Maintenance: It’s crucial to regularly maintain your vehicle according to manufacturer recommendations. This includes keeping tires inflated at the correct pressure, replacing damaged or malfunctioning sensors, and performing routine inspections.
  • Environmental Factors: Weather conditions can affect cameras and sensors, which in turn can affect the accuracy of ADAS systems. Calibrating in a controlled environment, such as an indoor facility, can help ensure accuracy and reliability.
  • Proper Use: It’s important to use ADAS features as intended. This means relying on your own driving skills and not solely depending on the technology. Always keep your hands on the wheel and be aware of your surroundings.
  • Updates and Recalibration: As technology continues to advance, it’s crucial to stay up-to-date with software updates for ADAS systems. Additionally, recalibration may be necessary after any repairs or replacements are made to the vehicle.
