GALLANT - Galileo for Safety of Life Applications of Driver Assistance in Road Transport
Overview
Background & policy context:
GALLANT is a pilot project under the Growth thematic programme of the 5th Research Framework Programme of the European Union. Together with the Galilei study, it forms part of on-going research work for the Galileo programme. It is managed by the EU Directorate General for Energy and Transport. GALLANT is the follow-on to the ‘GALILEO Application for Road Safety and Mobility’ GALA Pilot Project, which focused on specifying the technical needs of an Advanced Driver Assistant System (ADAS) for the road environment. It is a significant improvement over the prototype system developed in recent years within different national and international initiatives, using GPS integrated with ADAS.
Objectives:
GALLANT is a Pilot Project devoted to the application of the future Galileo for road transport safety and mobility. The project has addressed studies for the integration of Galileo with Advanced Driver Assistant Systems (ADAS) aiming the demonstration of the benefits coming from the integration of the satellite localisation system performances (e.g. increased availability, higher continuity level, possibility to have integrity information etc.).
Car manufactures, automotive and technology suppliers are cooperating since years for the development of ADAS systems at European level. Nevertheless, until the lunch of the GALLANT project, the experience has been led to the awareness of a more precise localisation service. With the next generation localisation system, the additional possibility to have a certified and reliable vehicle position (i.e. the system warns the user when the localisation service fails) will allow the ADAS application to reach the requested reliability as well as to resolve those cases which are not detectable by the on-board sensors.
Most of the ADAS applications considered in the GALLANT project involve the safety of the vehicle occupants and are considered belonging to the cluster of the safety of life applications which require high degree of accuracy, integrity and reliability/availability. Certification and guarantee of the service are mandatory to set a suitable level of liability from the service provider and for all the legal and institutional implications of this type of services. Safety of life applications will also take benefits from a precise localisation of the vehicle on the road network and into the road boundaries. Furthermore the association with high quality digital maps, in terms of accurate road geometry, allows a precise and reliable scenario reconstruction that is the prerequisite for all automatic actions. Mainly, the performances have been considered for the project are related to the accuracy, the integrity, the certification, the update rate, the continuity and the availability.
Anyway only for part of them it has been possible to test their potentiality in terms of benefits they could provide to the in-vehicle application. Those performances are related to the ones available and obtainable by the EGNOS system. For instance since November 2003 the EGNOS test bed has switched to the west European IOR satellite notifying, as it is reported within the test res
Methodology:
GALLANT focuses on ADAS. Car manufacturers, automotive suppliers and technology suppliers havebeen cooperating for some years in developing ADAS at the European level. Their growing experience has led to the awareness that sensors alone cannot fully satisfy all the specifications. GALLANT will investigate the contribution of Galileo to the following functions:
- Adaptive Cruise Control. The vehicle will automatically adapt its speed by using its Galileo location information and stored road characteristics;
- Overtaking Warning. Galileo positioning in the correct lane will help to detect other vehicles and avoid the false alarms that affect current systems;
- Vision Enhancement. A Galileo receiver supported by detailed map information will help to adapt vehicle headlights to road geometry, and will guarantee to warn users when the function is unavailable;
- Lane Warning and Keeping. Galileo could provide high accuracy and continuity in combination with a digital map;
- Collision Warning and Avoidance. Galileo positioning information and accurate mapping will allow ADAS to recognise the road geometry and avoid false alarms;
- Automatic Guidance. The vehicle is partially/fully controlled via a set of long- and short-range sensors around its, including certified Galileo positioning and precise digital road maps.
GALLANT will develop a demonstration version of Adaptive Cruise Control assisted by Galileo
