Abstract
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. In order to scan the vehicle's surrounding for potential crashes, up to date prototypic CA systems are based on on-board environmental sensors, such as camera or radar systems. The limited sensor covering area and the functionality of the used sensors under varying environmental conditions 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 process of the CA system the Galileo test centre "automotiveGATE" in Aldenhoven, Germany will be used. Pseudolites will be installed at the automotiveGATE which provide Galileo-like navigation signals and enable the development and tuning of Galileo based vehicle systems. Thus, these systems 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.
