Advanced driver assistance systems, or ADAS, are being installed in several of the new car models. This advancement in one area of automobiles is requiring that other advancements have to be made to accommodate this technology. Since most ADAS cameras are placed behind the windshield the quality of auto-glass, and the installation of it, needs advancement as well.
Glass standards for OE windshields are fairly strict with little variance. Aftermarket auto-glass does not have the same rigorous standards. This variation can effect clarity. Diminished clarity effects the light detection and ranging system (LIDAR) for ADAS. The LIDAR system must be calibrated to the clarity specifications of the windshield. Standard clarity regulations would allow ADAS to be utilized in vehicles without concern that the LIDAR is properly calibrated. The margin of error in calibration is a risk that could be avoided with higher quality auto glass that has standardized clarity and light specifications.
Installations methods are also in need of improvement to ensure this highly sensitive systems are installed correctly. Windshields equipped with LIDAR, that need replacing, cannot be replaced quickly. It takes considerable time to verify the angle of the windshield installation. The LIDAR system will not function correctly if the angle of the windshield is not at the exact angle specified as being required for that make, year, and model of vehicle.
Safety systems are a terrific advancement in the auto industry. Unfortunately, it requires advancements in other areas of the auto industry as well. Failure to do so will result in unnecessary accidents.
