Global automakers Toyota, BMW and insurer Allianz will license technology from Silicon Valley start-up Nauto, which uses cameras and artificial intelligence systems in cars to understand driver behavior, Nauto said on Friday. Nauto Chief Executive Stefan Heck told Reuters the carmakers and insurer will integrate the technology into their test vehicles and use the aggregate and anonymized data - whether on driving habits, difficult intersections, or traffic congestion - to help develop their autonomous vehicle strategies. The investment by BMWi Ventures, Allianz Ventures and the Toyota Research Institute underscores the auto industry's demand for smart systems to improve vehicle and driver safety, reduce liability and make fleet operations more efficient, while preparing for self-driving cars of the future. Terms of the deal were not disclosed, but the parties will each have an equity stake in Nauto. A third unnamed automaker also invested, Nauto said.
