What was once considered a feature for high-end luxuries is now becoming common, optional – sometimes even standard – features on today’s mid- and upper-range vehicles. Working in isolation or collaborating to proactively deliver notifications, warnings, and interventional actions to enhance driver safety.
These computer-driven systems rely on a combination of external sensors including cameras, radar, and LIDAR to identify objects, pedestrians, and potential hazards to provide advanced measures of safety and accident prevention. Cameras are mainly used for classification of the objects it sees as well as lane departure. Radar detects the existence of an object, its distance, and closing speed to the vehicle. LIDAR offers more precise detection of multiple objects, sensing capability at night, and provides redundancy in the system.
ADAS Active Safety Systems are Automatically Sensing the Environment Around the Vehicle
These high-performance devices either control the vehicle directly in a significant safety event or indicate to the driver that a change should be made to the vehicle’s operation. This “training” of the drivers to learn how to interact with this type of smart vehicle will prove to be one of the most significant challenges for successful ADAS implementation since it would require: 1. Changing a human’s habit (which is never fun and easy) 2. Will be different for each vehicle (OEMs are differentiating themselves through ADAS).
Now, think of the environment in which the highly sensitive electronics of ADAS operate. Not only are the cameras and sensors exposed to external harsh chemicals and oils, but also external elements of weather and road conditions, where they need to be protected from hard-hitting flying debris. Their, but their surfaces also need to keep clear when it rains or snows, as well as be resistant to oils in order to relay critical information accurately and in real-time. In addition, the cameras and sensors must have built-in thermal management to address the heat from the electronics. that does not dissipate on its own.
Henkel offers a variety of material solutions for ADAS cameras and radars to enable them to perform at optimal levels no matter the environment:
