The fast-paced development towards autonomous driving is demanding a change of the overall in-vehicle system architecture and a stronger cooperation between vehicles and infrastructure elements. Within the scope of running research activities PCC is developing an on-board-unit with focus on cooperative vehicle communication based on the 802.11p standard. New emerging challenges for autonomous driving is handled via a deep integration of the communication unit with the navigation unit. PCC is proposing a current state of the developed system with respect to a selected set of use cases.
