Abstract:	Driver assistance systems are a feature that can be found in almost every car from current series productions. In their origins, only parts of the driver’s tasks were aided, such as the optimal amount of brake power during maximum deceleration in an antilock system. The further development was aiming at adding comfort for the driver, such as navigation systems or headlight regulation devices. Ongoing research is aiming at partly automating traffic and linking road users with each other or the relevant infrastructure (Car2X). Potential applications share the need of the knowledge of the precise position of the involved vehicles. One key research area of the Institute of Flight Guidance is the development of positioning techniques for future vehicle applications. Several projects have been launched in which positioning modules for automotive systems are being developed. In this paper, the use of different positioning techniques for safety-relevant automotive systems is evaluated. Particularly the choice of an adequate GNSS algorithm coupled with current series vehicle sensors is reviewed. The aim of this analysis is the minimization of hardware effort while keeping up a feasible positioning performance. The paper closes with the presentation of a positioning system architecture that will be implemented in a research project funded by the German Federal Ministry of Economics and Technology.
