[{"publication":"2026 IEEE Intelligent Vehicles Symposium (IV)","abstract":[{"text":"The key to achieving energy efficiency and reducing carbon emissions in transportation lies in the effectiveness of vehicles and their associated mechatronic systems. 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.","lang":"eng"}],"date_created":"2026-07-20T06:18:02Z","department":[{"_id":"153"}],"type":"conference","keyword":["intelligent headlights","energy efficiency","ecodriving","decarbonization","matrix LED headlights","adaptive realtime control","ADAS systems","feedforward control","simulation"],"author":[{"full_name":"Fittkau, Niklas","first_name":"Niklas","orcid":"0009-0007-1281-4465","last_name":"Fittkau","id":"69890"},{"id":"51118","first_name":"Leon","last_name":"Bußemas","full_name":"Bußemas, Leon"},{"full_name":"Malena, Kevin","orcid":"0000-0003-1183-4679","last_name":"Malena","first_name":"Kevin","id":"36303"},{"id":"17793","last_name":"Gausemeier","first_name":"Sandra","full_name":"Gausemeier, Sandra"},{"first_name":"Ansgar","last_name":"Trächtler","full_name":"Trächtler, Ansgar","id":"552"}],"title":"Intelligent headlights boost energy efficiency and drive decarbonization","year":"2026","intvolume":"        37","date_updated":"2026-07-20T08:31:58Z","language":[{"iso":"eng"}],"citation":{"bibtex":"@inproceedings{Fittkau_Bußemas_Malena_Gausemeier_Trächtler_2026, place={Detroit, Vereinigte Staaten}, title={Intelligent headlights boost energy efficiency and drive decarbonization}, volume={37}, booktitle={2026 IEEE Intelligent Vehicles Symposium (IV)}, publisher={IEEE}, author={Fittkau, Niklas and Bußemas, Leon and Malena, Kevin and Gausemeier, Sandra and Trächtler, Ansgar}, year={2026} }","ama":"Fittkau N, Bußemas L, Malena K, Gausemeier S, Trächtler A.

The aim of the project is to investigate the influencing factors for a circular economy in the field of automotive lighting using the example of a headlamp. A key aspect is the analysis of methods for recycling end of life headlamps to recover materials for the next generation of headlamps and to evaluate their reusability. The article presents investigations and methods for recovering materials from used headlamps. These methods are evaluated based on how effectively they can recover materials for the next generation of headlamps and to what extent these materials can be reused. The goal was to identify the best practices that are both ecologically and economically sustainable. To support the development of a headlamp, a digital twin was created, which enables a detailed life cycle analysis at any time. This digital twin ensures that the expected CO2 footprint of the product can be analysed over its product life cycle during development to ensure optimal use and recycling of materials. This ensures a precise assessment of the environmental impact of future products. The final demonstrator of the project, developed based on the findings of the two points mentioned above and OEM requirements, presents the third key point of the research project: the design of a new product to enable a circular economy in the field of automotive lighting. The headlamp is designed to use circular economy recyclates and to serve as a material source at the end of its life. This represents an important step for automotive lighting towards a circular economy, where products and materials are used and reused for as long as possible.","lang":"eng"}],"project":[{"name":"Nachhaltigkeitsoptimiertes Life Cycle Assessment technologisch hochkomplexer Produkte am Beispiel Automobilbeleuchtung","_id":"693"}],"publication":"Proceedings of the 16th International Symposium on Automotive Lighting 2025","citation":{"mla":"Schmidt, Christian, et al. “Circular Economy Approaches in Automotive Lighting – Insights from the Nalyses Project.” <i>Proceedings of the 16th International Symposium on Automotive Lighting 2025</i>, 2025, doi:<a href=\"https://doi.org/10.26083/tuprints-00030841\">10.26083/tuprints-00030841</a>.","bibtex":"@inproceedings{Schmidt_Niedling_Helmig_Forbes_Jardin_Stieren_Fittkau_Peitzmeier_2025, place={Darmstadt}, title={Circular economy approaches in automotive lighting – insights from the Nalyses project}, DOI={<a href=\"https://doi.org/10.26083/tuprints-00030841\">10.26083/tuprints-00030841</a>}, booktitle={Proceedings of the 16th International Symposium on Automotive Lighting 2025}, author={Schmidt, Christian and Niedling, Mathias and Helmig, Jan and Forbes, Steffen and Jardin, Janis and Stieren, Stephan and Fittkau, Niklas and Peitzmeier, Henning}, year={2025} }","ama":"Schmidt C, Niedling M, Helmig J, 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.","lang":"eng"}],"place":"Darmstadt","date_created":"2025-09-24T08:56:38Z","oa":"1","department":[{"_id":"153"}],"type":"conference"}]
