Project Objectives

 
The objectives of the GENEVA project are
  • to develop an innovative application within the context of advanced driver assistance for high precision, reliable and certifiable use
  • to disburden the driver in complex traffic situations
  • to merge the state of the art sensor/actuator systems most efficiently
  • application will have clear market implementation focus using GNSS (GPS / EGNOS / Galileo) as primary positioning technology

Therefore an architecture of the GENEVA system has been envisioned where the vehicle platform acts as central element. The platform is able to communicate with an assistance and data server as well with local infrastructure if applicable. The vehicle platform is equipped with an in-vehicle-network which enables the subsystems to communicate between each other and to have real-time access to the sensors and actuators. The mentioned subsystems are the advanced driver assistance system (ADAS) and the positioning system.

The GNSS sensor is the most important sensor for the positioning system because it generates the absolute position-, velocity- and time-reference for the complete system. To fulfil this task in the context of GENEVA, the according automotive-specific requirements are introduced to the design and development of the GNSS (GPS, Galileo, EGNOS) receiver. According to automobile standards, the receiver will provide suitable interfaces to the existing on-board electronics and standard diagnostic interfaces. Using the integrity information broadcasted by Galileo and EGNOS (or EDAS alternatively) the driver assistance systems will get timely alerts about a deterioration of the navigation solution. The hardware will be tested and validated against the application requirements.


The main focus of the Urban Assist application is collision avoidance. In the context of the GENEVA project two specific intersection scenarios will be demonstrated: the "left turn assistance" and the "stop line assistance". In the first case the driver will get a warning if oncoming traffic may collide with the own vehicle. It is important to have a lane assignment for all perceived objects and the own vehicle. This is only possible with a reliable localization of the car and a precise map of the intersection. In the second scenario the driver will get a warning, if a stop line is overseen.

The challenges for both applications are integrity of the localization as well as the validity of the mapping data. For safety relevant systems only a very low false alarm rate is tolerated. If a sufficiently low false alarm rate cannot be guaranteed, no actuator intervention would be tolerated by the customers and the potential for safety enhancement is reduced.
