Innovations and new functions in modern automobiles are to a great extend based on data exchanged with sensors and actuators, integrated into the car itself. This limitation to onboard sensors results in a very constrained perception of the environment and thus only restricted possibilities to identify oncoming dangers and obstructions. A step to a better and more efficient real time data acquisition can be done by implementing C2CC (car to car communication). The usage of sensor data and information from many vehicles in the surrounding area results in a much more effective lookahead. Various C2CC applications are proposed ranging from driver information and traffic flow control to safety relevant functions for crash avoidance, driver assistance and possibly infotainment. Surveyed is the issue from the view of implementation and integration into the existing automotive network and gateway structure. In order to provide the required performance and flexibility we describe a reconfigurable hardware architecture offering solutions to meet the real time and security constraints.
