How Eggplants teach Autonomous Vehicles to see

Learning from nature with unlikely technologies

The world´s largest and 130 year-old producer of vehicle coating PPG Industries Inc. engineers a paint that allows autonomous cars recognizing his kind. Dark paint absorbes light which makes it hard for self-driving vehicles to detect black vehicles. PPGs special paint reflects near-infrared light of sensors that passes through the dark car´s exterior layer. Role model for this technology is the eggplant that uses the trick to keep cool on hot days. Because the surfaces of cars have to be detected by sensors in driverless vehicles, paintmakers have become key players in the race toward autonomous driving.
