The European Enhanced Vehicle-safety Committee wants to promote the use of more biofidelic child dummies and biomechanical based tolerance limits in regulatory and consumer testing. This study has investigated the feasibility and potential impact of Q-dummies and new injury criteria for child restraint system assessment in frontal impact. European accident statistics have been reviewed for all ECE-R44 CRS groups. For frontal impact, injury measures are recommended for the head, neck, chest and abdomen. Priority of body segment protection depends on the ECE-R44 group. The Q-dummy family is able to reflect these injuries, because of its biofidelity performance and measurement capabilities for these body segments. Currently, the Q0, Q1, Q1.5, Q3 and Q6 are available representing children of 0, 1, 1.5, 3 and 6 years old. These Q-dummies cover almost all dummy weight groups as defined in ECE-R44. Q10, representing a 10 year-old child, is under development. New child dummy injury criteria are under discussion in EEVC WG12. Therefore, the ECE-R44 criteria are assessed by comparing the existing P-dummies and new Q-dummies in ECE-R44 frontal impact sled tests. In total 300 tests covering 30 CRSs of almost all existing child seat categories are performed by 11 European organizations. From this benchmark study, it is concluded that the performance of the Q-dummy family is good with respect to repeatability of the measurement signals and the durability of the dummies. Applying ECE-R44 criteria, the first impression is that results for P- and Q-dummy are similar. For child seat evaluation the potential merits of the Q-dummy family lie in the extra measurement possibilities of these dummies and in the more biofidelic response.
Am 01.03.2004 wurde auf europäischer Ebene das Expertennetzwerk HUMANIST (HUMAN centred design for Information Society Technologies) eingerichtet, das sich mit Fragen der Implementierung, Gestaltung und Evaluation von Fahrerassistenz- und -informationssystemen aus einer sicherheits- und nutzerorientierten Perspektive befasst. Insgesamt sind 26 Partnerorganisationen aus 15 europäischen Ländern beteiligt. Nach bisher zwei Jahren Laufzeit kann das Netzwerk eine Vielzahl von erfolgreich durchgeführten Veranstaltungen vorweisen (verschiedene werden im Einzelnen aufgeführt). Darüber hinaus wurde ein Post-Graduierten- beziehungsweise ein Post-Doc-Programm ins Leben gerufen. Eine weitere wichtige Initiative bestand in der Beschaffung von Grundlagen für eine gemeinsame Nutzung der bei den beteiligten Partnern vorhandenen Forschungs-Infrastruktur und einer gemeinsam genutzten Datenbasis und virtuellen Arbeitsumgebung. Weiterhin konnten auch wissenschaftliche Ergebnisse erarbeitet werden, die in einigen wesentlichen Ausschnitten dargestellt werden. Dabei handelt es sich um folgende Themen: Nutzerbedürfnisse und Potenziale von Fahrerassistenz- und -informationssystemen; Auswirkung der Nutzung von Fahrerassistenz- und -informationssystemen auf das Fahrverhalten und ihre methodische Erfassung; Fahrerausbildung für die Nutzung von Fahrerassistenz- und -informationssystemen. Abschließend wird auf die im Jahr 2006 geplanten Aktivitäten hingewiesen.
Der Beitrag gibt den Inhalt eines Vortrags auf dem Forum des Deutschen Verkehrssicherheitsrats (DVR) 2006 in München wieder. Anhand der folgenden 4 Statements wird eine Einschätzung des möglichen Sicherheitsgewinns durch bisher entwickelte beziehungsweise in der Entwicklung befindliche Fahrerassistenzsysteme vorgenommen: 1) Ein hohes Unfallvermeidungspotenzial besteht für die Funktionen "Kreuzungsassistenz", "Unterstützung bei der Wahl einer situationsangepassten Geschwindigkeit" und "Kollisionswarnung/-vermeidung im Längsverkehr". 2) Ungefähr ein Drittel aller Unfälle kann nur durch aktiv eingreifende Fahrerassistenzsysteme verhindert werden. 3) Die erfolgversprechendsten Assistenzfunktionen sind äußerst komplex, bedürfen noch einigen Entwicklungsaufwands und ihrer Einführung stehen zum Teil erhebliche rechtliche Hürden gegenüber. 4) Ein hohes Sicherheitspotenzial bedeutet nicht unbedingt auch einen tatsächlich hohen Sicherheitsgewinn. Abschließend wird dargelegt, welche Maßnahmen dazu beitragen könnten, die Sicherheitspotenziale von Fahrerassistenzsystemen zu erschließen.
Das Projekt IMPROVER (Impact Assessment of Road Safety Measures for Vehicles and Road Equipment / Wirkungsanalyse und Bewertung von verschiedenen Verkehrssicherheitsmaßnahmen) wurde im Auftrag der Europäischen Kommission (Generaldirektion Energie und Verkehr) bearbeitet, um die folgenden Straßenverkehrssicherheitsaspekte zu untersuchen: den Einfluss der wachsenden Zahl von Sport Utility Vehicles (SUV) und Multi Purpose Vehicles (MPV) auf Verkehrssicherheit, Kraftstoffverbrauch und Emissionen; die Bewertung von Maßnahmen zur Verbesserung der Verkehrssicherheit von leichten Nutzfahrzeugen; die Auswirkungen des Tempomaten auf Verkehrssicherheit, Kraftstoffverbrauch und Emissionen; die Harmonisierung von Verkehrszeichen und Markierungen auf dem Transeuropäischen Straßennetz (TERN) unter Verkehrssicherheitsgesichtspunkten. Das Projekt wurde von der Bundesanstalt für Straßenwesen (BASt) zusammen mit 14 Partnerinstituten von November 2004 bis Mai 2006 bearbeitet. Entsprechend den Aufgaben wurde das Projekt in vier voneinander unabhängige Subprojekte eingeteilt. Der vorliegende Artikel gibt eine Übersicht über die in den jeweiligen Unterprojekten geleisteten Arbeiten, deren Ergebnisse und die daraus abgeleiteten Empfehlungen.
As set out in the Terms of Reference, the objective of European Enhanced Vehicle-safety Committee (EEVC) Working Group (WG) 15 Car Crash Compatibility and Frontal Impact is to develop a test procedure(s) with associated performance criteria for car frontal impact compatibility. This work should lead to improved car to car frontal compatibility and self protection without decreasing the safety in other impact configuration such as impacts with car sides, trucks, and pedestrians. Since 2003, EEVC WG 15 served as a steering group for the car-to-car activities in the "Improvement of Vehicle Crash Compatibility through the development of Crash Test Procedures" (VC-COMPAT) project that was finalised at the end of 2006 and partly funded by the European Commission. This paper presents the research work carried out in the VC-COMPAT project and the results of its assessment by EEVC WG 15. Other additional work presented by the UK and French governments and industry " in particular the European industry - was taken into consideration. It also identifies current issues with candidate testing approaches. The candidate test approaches are: - an offset barrier test with the progressive deformable barrier (PDB) face in combination with a full width rigid barrier test - a full width wall test with a deformable aluminium honeycomb face and a high resolution load cell wall supplemented by the forces measured in the offset deformable barrier (ODB) test with the current EEVC barrier. These candidate test approaches must assess the structural interaction and give information of frontal force levels and compartment strength for passenger vehicles. Further, this paper presents the planned route map of EEVC WG 15 for the evaluation of the proposed test procedures and assessment criteria.
At the 2005 ESV conference, the International Harmonisation of Research Activities (IHRA) side impact working group proposed a 4 part draft test procedure, to form the basis of harmonisation of regulation world-wide and to help advances in car occupant protection. This paper presents the work performed by a European Commission 6th framework project, called APROSYS, an further development and evaluation of the proposed procedure from a European perspective. The 4 parts of the proposed procedure are: - A Mobile Deformable Barrier test; - An oblique Pole side impact test; - Interior headform tests; - Side Out of Position (OOP) tests. Full scale test and modelling work to develop the Advanced European Mobile Deformable Barrier (AE-MDB) further is described, resulting in a recommendation to revise the barrier face to include a bumper beam element. An evaluation of oblique and perpendicular pole tests was made from tests and numerical simulations using ES-2 and WorldSID 50th percentile dummies. It was concluded that an oblique pole test is feasible but that a perpendicular test would be preferable for Europe. The interior headform test protocol was evaluated to assess its repeatability and reproducibility and to solve issues such as the head impact angle and limitation zones. Recommendations for updates to the test protocol are made. Out-of-position (OOP) tests applicable for the European situation were performed, which included additional tests with Child Restraint Systems (CRS) which use is mandatory in Europe. It was concluded that the proposed IHRA OOP tests do cover the worst case situations, but the current test protocol is not ready for regulatory use.
The use of proper child restraint systems (CRS) is mandatory for children travelling in cars in most countries of the world. The analysis of the quantity of restrained children shows that more than 90% of the children in Germany are restrained. Looking at the quality of the protection, a large discrepancy between restrained and well protected children can be seen. Two out of three children in Germany are not properly restrained. In addition, considerable difference exists with respect to the technical performance of CRS. For that reason investigations and optimisations on two different topics are necessary: The technical improvement of CRS and the ease of use of CRS. Consideration of the knowledge gained by the comparison of different CRS in crash tests would lead to some improvements of the CRS. But improvement of child safety is not only a technical issue. People should use CRS in the correct way. Misuse and incorrect handling could lead to less safety than correct usage of a poor CRS. For that reason new technical issues are necessary to improve the child safety AND the ease of use. Only the combination of both parts can significantly increase child safety. For the assessment of the safety level of common CRS, frontal and lateral sled tests simulating different severity levels were conducted comparing pairs of CRS which were felt to be good and CRS which were felt to be poor. The safety of some CRS is currently at a high level. All well known products were not damaged in the performed tests. The performance of non-branded CRS was mostly worse than that of the well known products. Although the branded child restraint systems already show a high safety level it is still possible to further improve their technical performance as demonstrated with a baby shell and a harness type CRS.
A legform impactor with biofidelic characteristics (FlexPLI) which is being developed by the Japanese Automobile Research Institute (JARI) is being considered as a test tool for legislation within a proposed Global Technical Regulation on pedestrian protection (UNECE, 2006) and therefore being evaluated by the Technical Evaluation Group (TEG) of GRSP. In previous built levels it already showed good test results on real cars as well as under idealised test conditions but also revealed further need for improvement. A research study at the Federal Highway Research Institute (BASt) deals with the question on how leg injury risks of modern car fronts can be revealed, reflected and assessed by the FlexPLI and how the impactor can be used and implemented as a legislative instrument for the type approval of cars according to current and future legislations on pedestrian protection. The latest impactor built level (GTα ) is being evaluated by a general review and assessment of the certification procedure, the knee joint biofidelity and the currently proposed injury criteria. Furthermore, the usability, robustness and durability as a test tool for legislation is examined and an assessment of leg injuries is made by a series of tests with the FlexPLI on real cars with modern car front shapes as well as under idealised test conditions. Finally, a comparison is made between the FlexPLI and the current european legislation tool, the legform impactor according to EEVC WG 17.
The PDB, BASt and Opel conducted two test series to evaluate possible effects on the results obtained using the EEVC WG17 Lower Legform Impactor as a test tool for the assessment of pedestrian safety. The reproducibility and repeatability of the test results were assessed using six legform impactors while keeping the test parameters constant. In the second series one impactor was used and the test parameters were varied to assess the effects on the readings of the legform. The test parameters were velocity, temperature, relative humidity, the point of first contact regarding the deviation in z-direction and the deviations of the pitch, roll and yaw angle. The tests were performed using an inverse setup, i.e. the legform was hit by a guided linear impactor equipped with a honeycomb deformation element. This setup was chosen to be able to vary each single parameter while avoiding variations of the other test parameters at the same time. The test parameters were varied stronger than allowed in regulatory use in order to determine possible dependencies between the parameters and the readings which were acceleration, bending angle and shear displacement.
Powered Two Wheelers (PTWs) accidents constitute one of the road safety problems in Europe. PTWs fatalities represent 22% at EU level in 2006, having increased during last years, representing an opposite trend compared to other road users" figures. In order to reduce these figures it is necessary to investigate the accident causation mechanisms from different points of view (e.g.: human factor, vehicle characteristics, influence of the environment, type of accident). SAFERIDER project ("Advanced telematics for enhancing the SAFEty and comfort of motorcycle RIDERs", under the European Commission "7th Framework Program") has investigated PTW accident mechanisms through literature review and statistical analyses of National and In-depth accident databases; detecting and describing all the possible PTW's accident configurations where the implementation of ADAS (Advanced Driver Assistance Systems) and IVIS (In-Vehicle Information Systems) could contribute to avoid an accident or mitigate its severity. DIANA, the Spanish in-depth database developed by CIDAUT, has been analyzed for that purpose. DIANA comprises of accident investigation teams, in close cooperation with police forces, medical services, forensic surgeons, garages and scrap yards. An important innovation is the fact that before injured people arrive to hospitals, photographs and explanations about the possible accident injury mechanisms are sent to the respective hospitals (via 3G GPRS technology). By this, additional information to medical staff can be provided in order to predict in advance possible internal injuries and select the best medical treatment. This methodology is presented in this paper. On the other hand, the main results (corresponding to road, rider and PTW characteristics; pre and post-accident manoeuvres; road layout; rider behaviour; impact points; accident causations;...) from the analyses of the PTW accidents used for SAFERIDER are shown. Only accident types relevant to ADAS and IVIS devices have been considered.
