Abstract

The goals of the project NAV-CAR are both to enable lane sensitive navigation for cars on highways and to increase robustness for high precision positioning in specific environments such as urban canyons and alpine regions where satellite based navigation systems may fail. The challenge of the project is the technical realization with a reasonable ratio of accuracy vs. costs, which is met by using sensor fusion technologies and stepwise integration of car specific data with GPS, which was implemented via an on-board unit (OBU) with CAN-bus interface. The approach was validated by test drives on urban (Vienna, A 23) as well as alpine highways (Brenner, A11/A12). Precise lane-specific trajectory reference data were derived from test drives with a special surveillance truck RoadStar. To estimate the potential impact of Galileo services as compared to existing GPS a simulation with data input from test drives in an alpine region was performed. The generation and inclusion of enhanced maps as a further option was evaluated.
