The resulting prediction framework uses decision tree ensemble models combined with certain model knowledge to forecast different control strategies. This method was chosen due to its best performance in various test scenarios. Very high accuracy and fidelity were achieved for standard control methods like fixed-time, time-of-day-based and 'ordinary' traffic-based programs. Only for the more sophisticated model predictive control which was tested lower accuracies were achieved.\r\nFor the upcoming GLOSA application the penetration of equipped vehicles was varied for different traffic scenarios and control strategies. Results showcase high potentials for enhancing urban mobility and reducing environmental impact by lower emissions and waiting times. However, it is also clear from the studies presented in this contribution that the coordination of the control strategy with the GLOSA vehicles is of enormous importance." author: - first_name: Kevin full_name: Malena, Kevin id: '36303' last_name: Malena orcid: 0000-0003-1183-4679 - first_name: Christopher full_name: Link, Christopher id: '38249' last_name: Link - first_name: Sandra full_name: Gausemeier, Sandra id: '17793' last_name: Gausemeier - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler citation: ama: 'Malena K, Link C, Gausemeier S, Trächtler A.

A notable example of a mechatronic system is the headlamp at the front of a vehicle, which emits adaptive headlights, such as the well-known adaptive cornering lights or glare-free high beam. The rise of these and other Advanced Driver Assistance Systems (ADAS) has led to a proliferation of sensor data. However, the full potential of ADAS sensor data for increasing energy efficiency has not yet been exploited in the past. This study demonstrates that utilizing the data to dynamically adapt headlights to the upcoming driving scenario leads to a substantial reduction in power consumption. This objective is pursued by focusing on the predominant carbon footprint driver, namely the low beam. author: - first_name: Niklas full_name: Fittkau, Niklas id: '69890' last_name: Fittkau orcid: 0009-0007-1281-4465 - first_name: Leon full_name: Bußemas, Leon id: '51118' last_name: Bußemas - first_name: Kevin full_name: Malena, Kevin id: '36303' last_name: Malena orcid: 0000-0003-1183-4679 - first_name: Sandra full_name: Gausemeier, Sandra id: '17793' last_name: Gausemeier - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler citation: ama: 'Fittkau N, Bußemas L, Malena K, Gausemeier S, Trächtler A.

Conventional heating, ventilation, and air conditioning (HVAC) systems rely on numerous air outlet temperature sensors, which add significant costs at scale. This study introduces a hybrid virtual sensor concept that combines physics-based mathematical modeling with data-driven methods to address this challenge. A detailed physical model predicts air outlet temperatures, while neural networks capture unmodeled heat exchanges and environmental disturbances. Two hybrid strategies are explored: one augments the physical model with a neural network to learn residual heat flows, and the other employs an adiabatic physical model enhanced by a neural network that maps the total environmental heat exchange, supported by a disturbance observer for accurate heat flow estimation. Evaluation using measurement data from a real test vehicle in a simplified two-vent scenario demonstrates that hybrid virtual sensors can provide reliable temperature estimates, reduce reliance on hardware sensors, and maintain high control performance, highlighting the potential of integrating physics-based and machine learning methods in vehicle climate control systems.' author: - first_name: Julia Magdalena full_name: Timmermann, Julia Magdalena id: '15402' last_name: Timmermann - first_name: Patrick full_name: Biemelt, Patrick last_name: Biemelt - first_name: Changcheng full_name: Li, Changcheng last_name: Li - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Eduard full_name: Pankratz, Eduard last_name: Pankratz citation: ama: 'Timmermann JM, Biemelt P, Li C, Trächtler A, Pankratz E.

Ein möglicher Ansatz, um Bauteilfälschungen z.B. in der Luft- und Raumfahrtindustrie sowie im Automotive-Bereich künftig zu verhindern, besteht darin, einen unverwechselbaren, unumkehrbaren „Identifier“ in das Originalbauteil zu integrieren. Dies könnte beispielsweise ein unsichtbarer magnetischer Bar- oder QR-Code sein, der während der Fertigung direkt in das Bauteil integriert wird. Die gezielte Beeinflussung der magnetischen Eigenschaften während des Fertigungsprozesses von Bauteilen durch die Umformtechnik stellt nach aktuellem Stand der Technik eine anspruchsvolle Herausforderung dar. Ein vielversprechender Forschungsansatz zur Lösung dieses Problems ist das Konzept der sogenannten Eigenschaftsregelung. Bei diesem Konzept werden die Bauteileigenschaften mittels intelligenter Sensoren direkt während der Fertigung gemessen und durch die Maschinenaktorik in den Prozess zurückgekoppelt. Dies ermöglicht eine dynamische Anpassung der Fertigungsparameter, um die gewünschten Eigenschaften des Bauteils zu erreichen. Dieser Beitrag beleuchtet am Beispiel des Drückwalzprozesses für metastabil-austenitischer Edelstähle, wie mit einer solchen Eigenschaftsregelung definierte und gradierte Eigenschaftsstrukturen z.B. zur Verhinderung von Produktfälschungen hergestellt werden können. Eine Hauptherausforderung bei der Entwicklung der Eigenschaftsregelung für das Drückwalzen metastabil-austenitischer Edelstähle ist insbesondere die Online-Messbarkeit des Gefüges in-situ im Prozess. Hierzu ist innerhalb der Eigenschaftsregelung eine indirekte, zerstörungsfreie Messung mittels einer neuartigen, intelligenten Softsensorik unabdingbar. Diese Sensorik besitzt eine charakteristische Dynamik und Ortsauflösung, welche mittelbar die Auflösung der geregelt erzeugten Gradierungen beeinflusst, d.h. die Schärfe der Abgrenzung zwischen martensitischen und nicht-martensitischen Bereichen. Dieser Aspekt wird Rahmen des vorliegenden Beitrags im Rahmen einer Simulationsstudie näher beleuchtet und ein Quervergleich zwischen Sensordynamik, Regelungsbandbreite und resultierenden und der erreichbaren Gradierungsauflösung gezogen. Insbesondere der letzte Aspekt ist von hoher Relevanz für einen etwaigen zukünftigen Technologietransfer der smarten, funktionsintegrierten Strukturen von der Forschung in die industrielle Anwendung. author: - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Bahman full_name: Arian, Bahman id: '36287' last_name: Arian - first_name: Julian full_name: Rozo Vasquez, Julian last_name: Rozo Vasquez - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Frank full_name: Walther, Frank last_name: Walther citation: ama: 'Kersting L, Arian B, Rozo Vasquez J, Trächtler A, Homberg W, Walther F.

However, the TRIP effect during flow forming is significantly affected by disturbances and especially batch fluctuations leading to process uncertainty. This aspect is further analyzed and quantified in this paper to give insights on how to minimize the impact of uncertainty. For this purpose, semifinished parts and resulting flow forming workpieces are systemically characterized concerning their properties and the property uncertainty supported by mathematical methods like correlation analysis and error propagation. A result is that the most influencing impact factor on the strain induced α’-martensite volume fraction as a material property are batch fluctuations, specifically the variations of the chemical composition. Those especially appear from batch to batch, but also within a batch accompanied by e.g. temperature effects. To counter this challenge, different methods from control theory like closed-loop property control and adaptive control can be applied to flow forming. Thus, uncertainty will be reduced to increase process robustness and to enable industrial exploitation of the TRIP effect in flow forming of metastable austenitic steels. article_type: original author: - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Mustafa full_name: Koyuncu, Mustafa last_name: Koyuncu - first_name: Bahman full_name: Arian, Bahman id: '36287' last_name: Arian - first_name: Julian full_name: Rozo Vasquez, Julian last_name: Rozo Vasquez - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Frank full_name: Walther, Frank last_name: Walther citation: ama: Kersting L, Koyuncu M, Arian B, et al.

Hierdurch entsteht ein heterogener Datensatz, bestehend aus einer hohen Anzahl an Daten mit unterschiedlichen Modalitäten. Dieser Beitrag untersucht anhand des Stanzbiegeprozesses eine Automatisierungsarchitektur mittels AAS-Einbindung, die die heterogenen Datensätze automatisiert akquiriert, verarbeitet und maschinenlesbar zur Verfügung stellt. Hierdurch wird einem Machine Learning Modul ermöglicht, die Wirkzusammenhänge zwischen Prozessparametern und Messdaten zu erlernen und anhand dessen eine optimierte Werkzeugauslegung für spezifische Produktgeometrien auszugeben. Ein Fokus liegt auf der Schnittstelle der heterogenen Prozessdatenrepräsentation, mit der sowohl Anwender als auch ML-Modul interagieren. Diesbezüglich werden zwei Ansätze analysiert und hinsichtlich ihrer Performanz sowie Skalierbarkeit bewertet, um so die Basis für ein anwenderorientiertes Assistenzsystems zur Werkzeugauslegung für Umformprozesse zu bilden. author: - first_name: Henning full_name: Peters, Henning last_name: Peters - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler citation: ama: 'Peters H, Kersting L, Trächtler A.

The resulting deviations are currently countered iteratively using expert knowledge in the design phase as well as during the production process. However, this is not always successful due to the complex interactions between semi-finished product properties and forming tools. To automate the optimization of tool geometries and process adjustments, an accurate prediction model of correlations between process/tool parameters and product properties is necessary. In that regard, an application programming interface (API) aligned with the Asset Administration Shell (AAS) specification is developed utilizing a hybrid data-driven approach. It enables the transformation of various data formats e.g., from sensor and simulation data into a machine-readable structure. The API is linked to a digital twin and a database, to automatically gather requested information and provide the new structured data to a machine learning (ML) model. To validate the developed method, hybrid punch-bending data is automatically transferred to an ML model which then returns tool geometry suggestions for a defined product geometry. article_type: original author: - first_name: Henning full_name: Peters, Henning last_name: Peters - first_name: Andreas full_name: Mazur, Andreas last_name: Mazur - first_name: Brijesh full_name: Chaudhary, Brijesh last_name: Chaudhary - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Barbara full_name: Hammer, Barbara last_name: Hammer citation: ama: Peters H, Mazur A, Chaudhary B, Kersting L, Trächtler A, Hammer B.

Within the punch-bending process semi-finished products of strip or wire material are formed and punched in several subsequent steps into a finished product like brackets, mounts, contacts or spring elements. In the context of those multi-stage straightening and bending processes, cross-stage and quantity-dependent effects significantly leads to undesired component deviations. To optimize the punch-bending process with regard to these component deviations and thus the waste rate, the concept of a hybrid data-driven model is presented. To automatically acquire and process this hybrid data while also enable the usage by multiple clients, a digital twin has to be developed. In this paper the communication infrastructure between the punch-bending system and the digital twin is presented, using the Asset Administration Shell as specification. This automated communication is validated using exemplary data from the punch-bending system. author: - first_name: Henning full_name: Peters, Henning last_name: Peters - first_name: Andreas full_name: Mazur, Andreas last_name: Mazur - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Barbara full_name: Hammer, Barbara last_name: Hammer citation: ama: 'Peters H, Mazur A, Trächtler A, Hammer B.

Flow forming is recognized for its precision in producing rotationally symmetric components, but the use of metastable austenitic stainless steel (AISI 304L) introduces challenges due to uncontrolled strain-induced α’ martensite formation. Variations in factors such as eccentricity and batch inconsistencies lead to unpredictable microstructural profiles, limiting reproducibility [1,2]. This study addresses these issues by incorporating thermal actuators for cryogenic cooling and induction heating to regulate forming temperatures, enabling control of the α’-martensite content. Experimental investigations demonstrate that local tempering during thermomechanical reverse flow forming produces discernible variations in microstructure, affecting mechanical and magnetic properties [3]. Controlled local adjustments of α’-martensite content allow for customization of properties in seamless tubes, advancing manufacturing capabilities for complex, defect-free components. The results presented demonstrate promising strategies for implementation within the context of closed-loop property control in flow forming. author: - first_name: Bahman full_name: Arian, Bahman id: '36287' last_name: Arian - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Julian full_name: Rozo Vasquez, Julian last_name: Rozo Vasquez - first_name: Frank full_name: Walther, Frank last_name: Walther citation: ama: 'Arian B, Homberg W, Kersting L, Trächtler A, Rozo Vasquez J, Walther F.

The plastic deformation triggers a phase transformation of the metastable austenite into α’-martensite.\r\n Depending on the combination of production parameters, different fractions of strain-induced α’-martensite were measured by means non-destructive micromagnetic techniques and correlated with the evolution of hardness and the microstructure using electron backscatter diffraction analyses. The magneto-optical Kerr effect analysis was used as a tool to perform a qualitative analysis of the evolution of the magnetic domain structure correlated with the formation of α’-martensite. An analysis of these data allowed to derive surface magnetization hysteresis loops that were compared with integral hysteresis loops of the specimens. It was proven by both methods that the formation of martensite increases the magnetic energy and the spontaneous magnetization of the specimens. The results of this investigation contribute to a better understanding of micromagnetic sensors to monitor and control the formation of α’-martensite in a flow forming. Furthermore, various techniques have demonstrated the evolution of the magnetic properties of the material, which can be applied in applications for invisible coding of workpieces." author: - first_name: Julian full_name: Rozo Vasquez, Julian last_name: Rozo Vasquez - first_name: Jan full_name: Tappe, Jan last_name: Tappe - first_name: Bahman full_name: Arian, Bahman id: '36287' last_name: Arian - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Frank full_name: Walther, Frank last_name: Walther citation: ama: Rozo Vasquez J, Tappe J, Arian B, et al.

The incremental flow forming process features a large number of process parameter combinations that can be varied from pass to pass or during a pass. In the future however, a more efficient utilization of this large number of process parameter combinations and a compensation of process disturbances could be required. This is due to a rising demand for increasing the part complexity, e.g. by graded property structures or a more complex geometry. In this context, innovative approaches like closed-loop property control and optimal control are advantageous, but require fast process models of flow forming that are not state of the art. This paper thus proposes a new modelling approach of multi-pass flow forming especially taking the transfer behavior between process parameters and wall thickness evolution from pass to pass into focus. A hybrid modelling approach is developed that combines knowledge about the incremental process character with empirical data regression to a basic analytic relation. The basic relation is further extended by a multi-layer neural network to enhance the overall model accuracy. This hybrid modelling approach is finally validated using experimental data. Thus, it is shown that a suitable model structure was found in context of a future closed-loop control or optimal control for multi-pass flow forming. author: - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Sharin Kumar full_name: Gunasagran, Sharin Kumar last_name: Gunasagran - first_name: Bahman full_name: Arian, Bahman id: '36287' last_name: Arian - first_name: Julian full_name: Rozo Vaszquez, Julian last_name: Rozo Vaszquez - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Frank full_name: Walther, Frank last_name: Walther citation: ama: 'Kersting L, Gunasagran SK, Arian B, et al.

Research by the publicly funded Nalyses project and the HELLA\r\ncompany shows that the headlamps use phase makes a significant contribution to the life\r\ncycle footprint taking into account the current electricity mix [1]. Today, functionalities\r\nsuch as adaptive curve light or glare-free high beam ensure comfort and safety by\r\nassessing the state of the vehicle and evaluating the driving scenario ahead. In future,\r\nthis evaluation will be expanded and used to adapt the headlamp to the driving scenario\r\nin such a way that as little light as possible is emitted, but as much light as necessary. In\r\norder to achieve this goal, an overall evaluation of the regulatory compliant energy\r\nsaving potential is crucial in a first step and leads to constraints for a dynamic adaption\r\nwhile driving. In this paper, the potential is illustrated by evaluating UNECE Regulation\r\nNo. 149 and optimizing luminous intensity distributions. Depending on the different\r\nresolutions of matrix LED headlamps, this approach can result in a significantly lower\r\nluminous flux. On the other hand, the results are point-like distributions that raise the\r\nquestion of whether the regulation still provides for sensible minimum requirements for\r\nmodern matrix LED headlamps. The results are further presented in a simulated virtual\r\nenvironment with regard to the resulting luminance in different driving scenarios. We\r\nthen present an approach to integrate regulatory requirements into a control algorithm by\r\nsetting optimization constraints and saturating the control. Finally, we classify the found\r\nluminous intensity distributions qualitatively according to common lighting criteria. In summary, although the investigated minimum distributions are by no means desirable\r\nfor drivers themselves, they form the basis on which energy-saving distributions for\r\nilluminated areas and twilight scenarios could be adaptively controlled in the future." author: - first_name: Niklas full_name: Fittkau, Niklas id: '69890' last_name: Fittkau orcid: 0009-0007-1281-4465 - first_name: Leon full_name: Bußemas, Leon id: '51118' last_name: Bußemas - first_name: Kevin full_name: Malena, Kevin id: '36303' last_name: Malena orcid: 0000-0003-1183-4679 - first_name: Sandra full_name: Gausemeier, Sandra id: '17793' last_name: Gausemeier - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler citation: ama: 'Fittkau N, Bußemas L, Malena K, Gausemeier S, Trächtler A.
