Die Level kontinuierlicher Fahrzeugautomatisierung sind unter Fahrerassistenzexperten weithin bekannt und erleichtern das Verständnis. Sie können aber nicht Fahrzeugautomatisierung insgesamt zufriedenstellend beschreiben: Insbesondere temporär intervenierende Funktionen, die in unfallnahen Situationen eingreifen, können offensichtlich nicht nach dem Level kontinuierlicher Fahrzeugautomatisierung beschrieben werden. Diese beschreiben nämlich die zunehmende Aufgabenverlagerung vom Fahrer zur maschinellen Steuerung bei zunehmendem Automatisierungsgrad. Notbremsfunktionen, beispielsweise, sind offensichtlich diskontinuierlich und nehmen zugleich auf intensive Weise Einfluss auf die Fahrzeugsteuerung. Sie lassen sich gerade nicht sinnvoll nach dem Level kontinuierlicher Fahrzeugautomatisierung beschreiben. Das Ergebnis kann indes nicht zufriedenstellen: Die fehlende Sichtbarkeit dieser Funktionen wird ihrer Bedeutung für die Verkehrssicherheit nicht gerecht. Daher wird hier, um ein vollständiges Bild der Fahrzeugautomatisierung zu erlangen, ein umfassender Ansatz zur Beschreibung verfolgt, der auf oberster Ebene nach Wirkweise unterscheidet. Auf dieser Basis lassen sich sowohl informierende und warnende Funktionen als auch solche, die nur temporär in unfallgeneigten Situationen intervenieren, im Detail beschreiben. Das ermöglicht es, eine eigenständige Klassifikation für unfallgeneigte Situationen zu erstellen. Dies kann für diese wichtigen Funktionen die eigenständige Sichtbarkeit herstellen, die ihrer Bedeutung gerecht wird.
Im Rahmen des weltweiten ESV-Programmes (Enhanced Safety of Vehicles) werden seit mehreren Jahren internationale Forschungsbemühungen unternommen (International Harmonized Research Activities, IHRA), um im Vorfeld der Gesetzgebung die wissenschaftlichen Grundlagen gemeinsam zu erarbeiten. Ziel der IHRA-Arbeiten ist es, auf der Grundlage dieser Forschungsergebnisse die Harmonisierung der Vorschriften zu erleichtern. Eine besondere Aktivität bezieht sich auf Intelligent Transportation Systems (ITS). Im vorliegenden Beitrag wird die Aufgabe dieser IHRA-ITS-Arbeiten geschildert, sowie der derzeitige Stand der Forschungsbemühungen beschrieben. Es zeigt sich, dass die beschriebene Sicherheitsbewertung eine Fülle von Fragestellungen aufwirft und weitere Forschungsanstrengungen erfordert. Die zukünftigen Bemühungen sind darauf gerichtet, in internationaler Zusammenarbeit und Arbeitsteilung die als besonders wichtig erkannten Themen zur Bewertung der fahrzeugseitigen Fahrerassistenzsysteme zu bearbeiten.
For a number of EU regulatory acts Virtual Testing (VT) is already allowed for type approval (see Commission Regulation No. 371/2010 of 16 April 2010 amending the Framework Directive 2007/46/EC). However, only a very general procedure on how to apply VT for type approval is provided. Technical details for specific regulatory acts are not given yet. The main objective of the European project IMVITER (IMplementation of VIrtual TEsting in Safety Regulations) was to promote the implementation of VT in safety regulations. When proposing VT procedures the new regulation was taken into account, in particular, addressing open issues. Special attention was paid to pedestrian protection as pilot cases. A key aspect for VT implementation is to demonstrate that the employed simulation models are reliable. This paper describes how the Verification and Validation (V&V) method defined by the American Society of Mechanical Engineers was adapted for pedestrian protection VT based assessment. or the certification of headform impactors an extensive study was performed at two laboratories to assess the variability in calibration tests and equivalent results from a set of simulation models. Based on these results a methodology is defined for certification of headform impactor simulation models. A similar study was also performed with one vehicle in the type approval test setup. Its bonnet was highly instrumented and subjected to 45 impacts in five different positions at two laboratories in order to obtain an estimation of the variability in the physical tests. An equivalent study was performed using stochastic simulation with a metamodel fed with observed variability in impact conditions of physical headforms. An estimation of the test method uncertainty was obtained and used in the definition of a validation corridor for simulation models. Validation metric and criteria were defined in cooperation with the ISO TC22 SC10 and SC12 WG4 "Virtual Testing". A complete validation procedure including different test setups, physical magnitudes and evaluation criteria is provided. A detailed procedural flowchart is developed for VT implementation in EC Regulation No 78/2009 based on a so called "Hybrid VT" approach, which combines real hardware based head impact tests and simulations. This detailed flowchart is shown and explained within this paper. Another important point within the virtual testing based procedures is the documentation of relevant information resulting from the verification and validation process of the numerical models used. For this purpose report templates were developed within the project. The proposed procedure fixes minimum V&V requirements for numerical models to be confidently used within the type-approval process. It is not intended to be a thorough guide on how to build such reliable models. Different modeling methodologies are therefore possible, according to particular OEM know-how. These requirements respond to a balance amongst the type-approval stakeholders interests. A cost-benefit analysis, which was also performed within the IMVITER project, supports this approach, showing the conditions in which VT implementation is beneficial. Based on the experience gained in the project and the background of the experts involved an outlook is given as a roadmap of VT implementation, identifying the most important milestones to be reached along the way to a future vehicle type approval procedure supported by VT. The results presented in this paper show an important step addressing open questions and fostering the future acceptance of virtual testing in pedestrian protection type approval procedures.
Fahrerassistenzsysteme unterstützen den Fahrer durch Information, Warnung oder Eingriff in die Fahrzeugsteuerung. Zukünftige Systeme zur Kollisionsvermeidung oder bis hin zum automatischen Fahren werden den Fahrer immer mehr entlasten. Wegen ihres erheblichen Potenzials zur Verbesserung vor allem der aktiven Sicherheit können die Fahrerassistenzsysteme wesentlich zur Vermeidung von Unfällen oder der Reduktion von Unfallfolgen beitragen. Andererseits können Fahrerassistenzsysteme aufgrund des komplexen Systemzusammenhangs zwischen Fahrer, Fahrzeug und Umwelt negative Auswirkungen auf das Verkehrsgeschehen haben. Dieser Aspekt muss schon bei der Entwicklung der Systeme berücksichtigt werden. Die Empfehlung der Europäischen Kommission zur Gestaltung von Informations- und Kommunikationssystemen gibt dazu Leitlinien vor. Die BASt ist mit der wissenschaftlichen Begleitung der Thematik beauftragt. Die Industrie ist dazu aufgefordert darzulegen, welche Maßnahmen zur Einhaltung der Grundsätze ergriffen worden sind beziehungsweise werden. Um das Potenzial der Fahrerassistenzsysteme zur Steigerung der Verkehrssicherheit voll ausschöpfen zu können, sind weiterhin Forschungsarbeiten zur Entwicklung neuer und zur Weiterentwicklung bestehender Systeme unter Berücksichtigung der Gestaltungsanforderungen für sichere Assistenzsysteme durchzuführen.
The project UR:BAN "Cognitive assistance (KA)" aims at developing future assistance systems providing improved performance in complex city traffic. New state-of-the-art panoramic sensor technologies now allow comprehensive monitoring and evaluation of the vehicle environment. In order to improve protection of vulnerable road users such as pedestrians and cyclists, a particular objective of UR:BAN is the evaluation and prediction of their behaviour and actions. The objective of subproject "WER" is development support by providing quantitative estimates of traffic collisions at the very start and predict potential in terms of optimized accident avoidance and reduction of injury severity. For this purpose an integrated computer simulation toolkit is being devised based on real world accidents (GIDAS as well as video documented accidents), allowing the prediction of potential effectiveness and future benefit of assistance systems in this accident scenario. Subsequently, this toolkit may be used for optimizing the design of implemented assistance systems for improved effectiveness.
A biofidelic flexible pedestrian legform impactor (FlexPLI) has been developed from the year 2000 onwards and evaluated by a technical evaluation group (Flex-TEG) of UN-ECE GRSP. A recently established UN-ECE GRSP Informal Group on GTR9 Phase 2 is aiming at introducing the FlexPLI within world-wide regulations on pedestrian safety (Phase 2 of GTR No. 9 as well as the new UN regulation 127 on pedestrian safety) as a test tool for the assessment of lower extremity injuries in lateral vehicle-to-pedestrian accidents. Besides, the FlexPLI has already been introduced within JNCAP and is on the Euro NCAP roadmap for 2014. Despite of the biofidelic properties in the knee and tibia sections, several open issues related to the FlexPLI, like the estimation of the cost benefit, the feasibility of vehicle compliance with the threshold values, the robustness of the impactor and of the test results, the comparability between prototype and production level and the finalization of certification corridors still needed to be solved. Furthermore, discussions with stakeholders about a harmonized lower legform to bumper test area are still going on. This paper describes several studies carried out by the Federal Highway Research Institute (BASt) regarding the benefit due to the introduction of the FlexPLI within legislation for type approval, the robustness of test results, the establishment of new assembly certification corridors and a proposal for a harmonized legform to bumper test area. Furthermore, a report on vehicle tests that previously had been carried out with three prototype legforms and were now being repeated using legforms with serial production status, is given. Finally, the paper gives a status report on the ongoing simulation and testing activities with respect to the development and evaluation of an improved test procedure with upper body mass for assessing pedestrian femur injuries.
The evaluation of the expected benefit of active safety systems or even ideas of future systems is challenging because this has to be done prospectively. Beside acceptance, the predicted real-world benefit of active safety systems is one of the most important and interesting measures. Therefore, appropriate methods should be used that meet the requirements concerning representativeness, robustness and accuracy. The paper presents the development of a methodology for the assessment of current and future vehicle safety systems. The variety of systems requires several tools and methods and thus, a common tool box was created. This toolbox consists of different levels, regarding different aspects like data sources, scenarios, representativeness, measures like pre-crash-simulations, automated crash computation, single-case-analyses or driving simulator studies. Finally, the benefit of the system(s) is calculated, e.g. by using injury risk functions; giving the number of avoided/mitigated accidents, the reduction of injured or killed persons or the decrease of economic costs.
In road traffic accidents, a car-seat and its occupant can be subjected to various crash pulses in the case of a rear impact. This study investigates the influence of crash pulse shape on seat-occupant response and evaluates the corresponding risk of whiplash injury. For this purpose, a rigorously validated seat-occupant system model is used to study different carseat designs and crash pulses. Two different car-seat concepts are also presented which can effectively mitigate whiplash injury for a wide range of crash severity. It is shown that for crash pulses of similar severity, the level of whiplash-risk depends strongly on the combined effects of seat design and crash pulse shape.
Since its creation in 2011 the Pre-Crash-Matrix (PCM) offers the possibility to observe the pre-crash phase until five seconds before crash for a wide range of accidents. Currently the PCM contains more than 8.000 reconstructed accidents out of the GIDAS (German In-Depth Accident Study) database and is enlarged continuously by more than 1.000 cases per year. Hence, a detailed investigation of active safety systems in real accident situations has been made feasible. The PCM contains all relevant data in database format to simulate the pre-crash phase until the first collision of the accident for a maximum of two participants. This includes the definition of the participants and their characteristics, the dynamic behavior of the participants as time-dependent course for five seconds before crash as well as the geometry of the traffic infrastructure. The digital sketch of the accident and information from GIDAS as well as from supplementary databases represent the main input for the simulation of the pre-crash phase of an accident with the VUFO simulation model VAST (Vufo Accident Simulation Tool). This simulation in turn embodies the foundation of the PCM. The PCM underlies continual improvements and enhancements in consultation with its users. In addition to collisions of cars with other cars, pedestrians, bicycles and motorcycles the PCM now also covers car to object and car to truck collisions. The paper illustrates car to truck collisions as a showcase and explains perspectives for further developments. In 2016 a more detailed definition of the contour of the vehicle was added. Furthermore, the geometrical surroundings of the accident site will be provided in a new structure with a higher level of detail. Thus, a precise classification of road marks and objects is possible to further improve the support of developing and evaluating ADAS. This paper gives an overview about the latest developments of the PCM with its innovations and provides an outlook to upcoming enhancements. Besides potential areas of application for the development of ADAS are shown.
Automated driving will provide many kinds of benefits - some direct and some indirect. The benefits originate at the individual level, from changes in the behaviour of drivers and travellers with regard to driving and mobility, ending up with benefits at the social level via changes in the whole transport system and society, where many of the current planning and operations paradigms are likely to be transformed by automated driving. There may also be disbenefits, particularly at a social level, for example in intensity of travel which could result in additional congestion and increased use of natural resources. There may also be unintended consequences. For example, we do not know the impacts on public transport: driverless vehicles could provide a means to a lower cost service provision, but the availability of automated cars could lead to more car travel at the expense of collective transport.
