Car-to-Car communication for accurate vehicle localization — The CoVeL approach

This paper presents the CoVeL system which aims to reach lane-level localization accuracy for Advanced Driver Assistance Systems. It highlights the potential of using raw GPS measurements in a cooperative system together with a high-accurate digital map. The focus of this paper is on the definition and the implementation of the Car-to-Car message extensions needed to transmit GPS measurements between vehicles. Furthermore, the integration of EGNOS/EDAS satellite corrections into C2C communication is motivated and shown. Finally, this work demonstrates how new communication technologies can successfully contribute to enhanced localization accuracy.
