PANE IN THE ADAS Windshield replacement in the ADAS era BY HOWARD BERG Howard Berg, regional sales manager— Canada at Fuyao North America Inc.
Ultimately, access to the ADAS requirements and glass specifications is key to making consistent ADAS glass. Different car manufacturers have different approaches to specific ADAS designs for their specific models.

DAS stands for advanced driver assistance system. It refers to any electronic system that assists the driver while driving and is intended to improve vehicle safety. It is estimated that nearly 40 percent of the new vehicles sold in Canada today have some sort of ADAS technology built into them. It is projected that figure could jump to more than 50 percent by 2023. This technology is designed to work together with other systems to automate the vehicle while enhancing its safety.This is done by warning the driver of potential issues and ultimately avoid collisions. Adaptive systems are ones that adapt vehicle settings based on input from the surrounding environment. Automated systems take over certain functions that the driver cannot do safely.Monitoring systems use sensors, cameras, or other means to observe the surrounding area or driving of the vehicle and assess whether a correction needs to be made. Warning systems alert the driver to potential issues in their own driving or the driving of others that could increase the risk of injury to those in the vehicle.
ADAS technology allows the systems in the vehicle to function properly and is built into a vehicle’s windshield. This technology will require more rigorous standards and qualifications for auto glass technicians. Replacing a broken windshield is not as simple as replacing the glass—some ADAS windshields have modules or cameras built into them that need to be calibrated in order to function properly Many features of ADAS are designed to capture external information through the windshields, allowing the vehicle’s computer to quickly analyze and efficiently provide the necessary action. The technology requires the automotive glass to meet or exceed the requirements in order to not reduce, distort or impede the signal, which ultimately may cause the vehicle to react incorrectly. As a result, automotive glass manufacturers must meet the requirements for the ADAS systems. These requirements include choosing the right raw materials, investing in product engineering, and setting up the proper quality inspection standards for production. Every car manufacturer has its own specifications for ADAS calibration. These differences range from manufacturer to manufacturer, and

in many instances, the same manufacturer will have differences from model to model. Only trust manufacturers who have the proven experience to produce the original specifications of auto glazing, which enable the ADAS system to be recalibrated. Precise calibration ensures correct pitch, yaw and roll of the camera. Ultimately, access to the ADAS requirements and glass specifications is key to making consistent ADAS glass. Different car manufacturers have different approaches to specific ADAS designs for their specific models. ADAS sensors or cameras are most commonly mounted on the glass. Once a windshield has been replaced, the position of the sensor or camera has ultimately changed—even the slightest change will cause the need for calibration. Recalibrating the camera or sensor after the replacement of the windshield is therefore necessary—whether or not OEM glass has been installed. In order to re-calibrate the ADAS windshields, special training, equipment and expertise are required. There are three types of calibrations: static, dynamic and a combination of the two.
