Galileo-based Collision Avoidance System

Nowadays, collision avoidance (CA) systems are an intensive research topic since the majority of all traffic accidents are collisions that are caused due to inattention or unadjusted driving behaviour of the driver. Up to date prototypic CA systems are based on on-board environmental sensors, such as camera or radar systems, in order to scan the vehicle’s surrounding for potential crashes. The functionality of the used sensors under varying environmental conditions and the limited sensor covering area require an enormous effort to ensure a reliable detection of obstacles, and thus limit the application of the systems.
In order to expand the operating field of such systems, a GALILEO-based CA system will be developed within the project GALILEO-above. This advanced driver assistance system detects surrounding vehicles that are on collision course, and react autonomous, if the driver does not intervene to avoid the crash. For this purpose the system initiates an emergency stop or an emergency steering.
For the development of the CA system the GALILEO test centre “Automotive Gate” in Aldenhoven, Germany will be used. On this test area pseudolites will be installed which provide GALILEO-like navigation signals. Thus, the development respectively tuning of GALILEO based vehicle systems will be enabled, so that they are available on the market when the GALILEO satellite system becomes operative.
At the end of the project GALILEO-above, first prototypes should demonstrate the potential of GALILEO-based collision avoidance systems.
In this paper the GALILEO-above project will be introduced followed by a detailed description of the development process of the CA system. Furthermore, first results will be presented.
