Gegenwärtig entwickelt die RWTH Aachen University im Rahmen des Projekts "Galileo above" (Anwendungszentrum für bodengebundenen Verkehr ) ein Kollisionsvermeidungssystem (Collision Avoidance System, CAS) unter Einbeziehung von Galileo-Daten. Ziel des CAS ist - wie der Name suggeriert - Fahrzeuge zu erkennen, die sich auf Kollisionskurs mit dem eigenen Fahrzeug befinden und automatisch eine kollisionsvermeidende Maßnahme (Bremsen und/oder Lenken) einzuleiten, insofern der Fahrer nicht rechtzeitig reagiert. Der begrenzte Erfassungsbereich und die Einschränkungen, der die verwendete kosten-optimierte Sensorik unter unterschiedlichsten Umgebungsbedingungen unterliegt, sind häufig ein begrenzender Faktor für die Realisierbarkeit und Robustheit von Fahrerassistenzsystemen (FAS). Der Einsatz von GNSS (Global Navigation Satellite System) in Verbindung mit einer digitalen Karte und Fahrzeug-zu-Fahrzeug- bzw. Fahzeug-zu-Infrastruktur-Kommunikation bietet das Potenzial, den Erfassungsbereich der Sensorik deutlich zu erweitern und diese unter schwierigen Umgebungsbedingungen zu stützen. Für die Entwicklung des CAS wird das Galileo Testzentrum automotiveGATE in Al-denhoven genutzt. Das automotiveGATE erweitert das Aldenhoven Testing Center um sogenannte Pseudoliten (Pseudo-Satelliten), welche Galileo-ähnliche Navigati-onsdaten in einem begrenzten Gebiet ausstrahlen. Das automotiveGATE ermöglicht somit die Entwicklung und Erprobung von Galileo-basierten Applikationen vor der Inbetriebnahme des eigentlichen Galileo-Satellitennavigationssystems. Im Rahmen dieses Beitrags werden Erläuterungen zur Perzeption und Sensorfusion, zur Deeskalationsstrategie und Eingriffsentscheidung sowie zu Testergebnissen bei Auffahrsituationen des CAS gegeben.

Currently the RWTH Aachen University is developing a collision avoidance system (CAS) using Galileo data within the framework of the project ‘Galileo above’ (application centre for ground based traffic). The needed Galileo-signals are emitted by so-called pseudolites (pseudo-satellites) installed on the automotiveGATE. The research project is sponsored by the Space Agency of the German Aero-space Centre (DLR) with funding by the Federal Ministry of Economics and Technology, in compliance with a resolution of the German Parliament (pro-ject/grant no. 50 NA 0902). This paper will give some de-tails on the perception and sensor fusion, the de-escalation and intervention decision as well as on first testing results regarding rear-end collisions. [less ▲]

Nowadays, collision avoidance systems (CAS) are an intensive research topic since the majority of all traffic accidents are collisions that are caused due to inattention or unadjusted driving behavior of the driver. Up to date prototypic CAS are based on on-board environmental sensors, such as camera or radar systems, that scan the vehicle's surrounding environment in order to assess the situation's hazardousness. 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 CAS will be developed within the project ‘Galileo above’ (application centre for ground based traffic). This advanced driver assistance system (ADAS) detects surrounding vehicles that are on collision course and reacts autonomously, if the driver does not intervene to avoid the crash. For this purpose the system initiates an emergency stop and/or an emergency steering maneuver. For the development of the CAS the Galileo test centre automotiveGATE 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 as to have them available on the market when the Galileo satellite system reaches its full operational capability (FOC). The focus of this paper is on the traffic situation assessment and intervention strategy of the CAS. This includes the perception and analysis of the driving situation, the detection of potential collision situation, the definition of an adequate system reaction and the planning of an evasion trajectory. Furthermore, an outlook on the model predictive control for longitudinal and/or lateral control (braking and/or steering maneuver) will be presented. [less ▲]

The performance that can be achieved by safety critical systems which are based on information on their absolute position inherently depends on the accuracy and the update rate that is provided by the navigation system. A Collision Avoidance System (CAS) that is intended to prevent collisions between vehicles by an autonomous braking resp. evasion maneuver is such a safety critical system and will be subject of consideration in this paper. In this context, the employed sensor fusion algorithm that provides a navigation solution with high update rate based on an inertial navigation system (INS) as well as on a Global Navigation Satellite System (GNSS) will be presented. Furthermore, a method to assess the actual accuracy provided by GNSS resp. sensor fusion will be introduced. Subsequently, the paper shows how this information can be incorporated into sensor fusion. Obviously, the feasibility of CAS inherently depends on the accuracy that can be obtained from GNSS. Therefore, CAS will be developed and tested in a terrestrial Galileo test and development environment (GATE) near Aachen (Germany) where a positional accuracy of about 0.8 meters can be achieved. Finally, first simulation results based on measurement data will be presented to evaluate the sensor fusion algorithm as well as the method to assess the actual navigation accuracy. [less ▲]

The full operational capability (FOC) of the European satellite navigation system Galileo is expected for 2016/2017. In contrast to today’s GPS Galileo will offer an enhanced availability, reliability and accuracy. Within the framework of “Galileo above” two terrestrial test environments are being set up under the supervision of RWTH Aachen University. The two test environments are the automotiveGATE for automotive applications which is being built on the area of the Aldenhoven Testing Center (ATC) in Aldenhoven and the railGATE for applications in the area of rail transportation which is going to be constructed on the premises of the Siemens testing and validation center in Wegberg-Wildenrath. These environments will allow the development and test of innovative Galileo based applications before the official launch of the global satellite system. In parallel a Galileo based collision avoidance system is developed and will be tested in the automotiveGATE. Also the federal state of North Rhine-Westphalia promotes research projects in the field of Galileo based driver assistance systems. [less ▲]

Advanced driver assistance systems do not only promise higher driving comfort, but potential benefit for an increase of safety especially for commercial vehicles. Accidents with involve- ment of commercial vehicles normally have severe consequences. The Institut für Kraftfahr- zeuge (ika) of the RWTH Aachen University with support from the Institute of Road and Traffic Engineering (isac) of the RWTH Aachen University have investigated in cooperation with the Federal Highway Research Institute (BASt) current and future ADAS for commercial vehicle in order to determine the potential for their benefit to increase road safety. Based on the accidents of official statistics and in-depth analysis of accidents from the GIDAS data base, relevant accident reasons are assessed systematically for a possible interference with selected ADAS. The qualitatively estimated safety potential results from the superposition of the main accident characterisation, the accident type and the accident category. A detailed estimation of the safety potential is conducted by means of simulations with the traffic flow simulation tool PELOPS. A cost-benefit analysis of the investigated systems is conducted.

Der Beitrag beschreibt die Funktionsentwicklung von Fahrerassistenzsystemen an der Forschungsgesellschaft Kraftfahrwesen mbH Aachen (fka) und am Institut für Kraftfahrwesen (ika) der RWTH Aachen mittels Fahrsimulatoren. Dabei wird konkret auf die Entwicklung eines Kreuzungsassistenten sowie eines sogenannten KONVOI-Systems eingegangen. Beide Systeme wurden u.a. unter Verwendung des statischen Fahrsimulators InDriveS entwickelt. Der in diesem Beitrag vorgestellte Ansatz eines Kreuzungsassistenten basiert auf Kommunikation: Fahrzeug-Fahrzeug-Kommunikation (C2C) und Infrastruktur-Fahrzeug- Kommunikation (I2C). Hierfür wurden in der Verkehrsfluss- und Fahrsimulation verschiedene Systemvarianten betrachtet, um unterschiedliche Stufen der Systemkomplexität und unter- schiedliche Zeitrahmen für die Realisierung eines solchen Assistenten zu berücksichtigen. Jede dieser Systemvarianten wurde hinsichtlich deren Wirkung auf die Verkehrssicherheit bewertet. Daneben wurde auch die Benutzerakzeptanz unter Berücksichtigung verschiedener Mensch-Maschine-Schnittstellen betrachtet. Die Ergebnisse zeigen, dass die Kommunikationsreichweite der wichtigste Parameter für die Systemauslegung und -spezifikation darstellt. Für die Wirkung des Kreuzungsassistenten auf die Verkehrssicherheit ist in erster Linie der Ausrüstungsgrad entscheidend. Für die Benutzerakzeptanz ist die Detektionsrate von möglichen Konfliktsituationen und die Vermeidung von kritischen Situationen entscheidend. Das dargestellte KONVOI-System ermöglicht die Automatisierung von Nutzfahrzeugkolonnen auf Autobahnen. Neben der Funktionsentwicklung zur automatischen Abstandsregelung und Querführung werden in dem Projekt die Auswirkungen von KONVOIs auf den übrigen Verkehr analysiert und die bei den Fahrern auftretenden Belastungen und die Akzeptanz des Systems untersucht. Begleitend werden rechtliche Aspekte der kommerziellen Nutzung von Lkw-KONVOIs in Deutschland weiterentwickelt. Um die Komplexität der zu entwickelnden Lösungen zur Funktionserweiterung der Fahrzeuge zu bewältigen und eine hohe Zuverlässigkeit der Systeme zu gewährleisten, erfolgt die Systementwicklung mit Hilfe von Simulationswerkzeugen (MATLAB/Simulink, Stateflow, Verkehrsflusssimulation PELOPS und Lkw- Fahrsimulator InDriveS). Abschließend geht der Beitrag auf den neuen dynamischen Fahrsimulator der RWTH Aachen ein. [less ▲]

In this experiment older and younger drivers were examined in a driving simulator when using in vehicle information systems (IVIS). An in-vehicle intersection assistant was developed, which informed drivers timely about the current traffic in the next intersection. In order to learn about the visual load, the intersection assistant was tested in two display sizes (a larger and a smaller interface). Independent variables were users’ age (young vs. old) and the size of the visual interface. As dependent variables, speed and accuracy of lane tracking was surveyed. Results showed an overall significant age-effect with older adults showing lower driving speed but an equally high line tracking accuracy compared to the younger group. Respecting the two sizes, it was found that the larger display led to a more careful and more accurate driving, especially in the critical traffic situations as intersection areas. [less ▲]
