M-CUBE/COLTOC

Traffic jams related to irregular traffic are a common problem that imposes immense societal costs on both citizens and public authorities. In this project, we develop a holistic cooperative optimization approach that explicitly targets delays caused by irregular traffic phenomena. The proposed approach aims to (i) assess the resilience of a transportation network, (ii) identify critical and vulnerable elements, (iii) reduce (ir)regular delays, (iv) identify dynamic bottlenecks, and (v) mitigate their negative impacts through new control approaches and dynamic speed recommendations. The collaboration between industry partners, government agencies, and academic partners will enable the project partners to develop implementation-ready tools, which will be tested at the 2024 State Garden Show.

Learn more about M-CUBE/COLTOC

Goal

To achieve this goal, COLTOC uses a new type of sensor developed in this project that is capable of measuring regular and irregular traffic phenomena. The new information will be used to develop multimodal traffic models capable of detecting and correcting traffic incidents due to irregular traffic patterns. This project is the first to explore the relationship between network topology, integrated mobility, connected and autonomous vehicles, and new sensor technologies. The expected outcome is a framework capable of delivering significant societal benefits (improved air quality, reduced travel times, sustainable modal shift) while boosting economic growth thanks to breakthroughs in sensor technology and automation.

SmartDelta

Digitization and automation increasingly lead to software-intensive systems and services and place high demands on industrial software development. Today, such software-intensive systems are rarely developed from scratch, but are incrementally assembled, integrated, and tailored to the needs of a specific customer, market, or region in short iteration cycles. Far too often, however, certain quality aspects of the system begin to deteriorate over time. It is therefore extremely important to be able to accurately analyze and determine the impact of each software change and enhancement on the quality of the entire software-intensive system.

SmartDelta develops automated solutions for the quality assessment of software increments for a continuous software development process. SmartDelta designs intelligent analysis methods based on development artifacts (e.g. source code, log files, requirements specifications), provides insights into the quality improvements or degradations of different software versions and provides recommendations for the next software versions.

Learn more about SmartDelta

Goal

  • The goal of SmartDelta is to develop automated solutions for the quality assessment of software products and versions in continuous software development processes. SmartDelta focuses in particular on the validation and verification of extra-functional requirements and the corresponding implementation, provision, and maintenance of test models as a basis for the realization of automated quality assurance activities. The concrete goals of SmartDelta are:
  • Automate model building by using natural language processing techniques and pattern-based approaches.
  • Establishment of an automated consistency check and validation of software increments
  • Reducing of the development, deployment, and feedback loops in software development
  • Reduction of quality assurance efforts for extra-functional properties

What is SmartDelta used for?

Software-intensive systems and services are not usually designed and implemented from scratch for each customer or order, but are delivered as a further development or as a modified version of an existing software product tailored to the needs of a specific customer, market or region. Over time, software companies manage increasing volumes of software products in various versions and levels of maturity that serve as the basis for subsequent reuse. Efficient creation and delivery of high-quality and secure software is only possible if the quality and maturity assessments as well as the quality assurance process are supported by a sufficient degree of automation.

SmartDelta develops automated solutions for software product and release quality assessment, enabling organizations to develop and deliver high-quality, trusted software systems in a fast-paced, agile environment.

    Our contributions to the project

    • Approach to transforming extra-functional requirements expressed in constrained natural language into formalized requirements models.
    • Automated generation of test cases from model checkers
    • Automated model-based testing of the system models against the formalized requirements based on automatically generated test cases
    • Approach to identifying cause-and-effect chains for problematic behavior in new software artifacts and making recommendations for improving the software based on these cause-and-effect chains.

    AINET-Antillas

    AINET-Antillas is a sub-project within the European AINET initiative. In various applications, such as Industry 4.0 and connected and autonomous driving, network availability and quality are of utmost importance to implement customer functions properly. AINET-Antillas develops and validates infrastructure elements for applications in highly networked scenarios. Tronis® is to be used for validating automated, connected and autonomous driving functions with regard to network quality; the latter also applies when comparing different network generations.

    Learn more about AINET-Antillas

    Goal

    AI-NET is aimed at creating a platform for the dynamic configuration of communication networks while they are running; a platform not only easy to use from a network operator's point of view, but also from the user's perspective. Via open descriptive interfaces ("intent-based"), the full potential of the infrastructure can thus be utilised along with seamless multi-cloud integration. Three sub-projects within the AINET framework develop solutions based on concrete, complementary application scenarios and implement them in demonstrators. The Antillas sub-project focuses on developing infrastructure elements for automated telecommunications networks with the aim of making them suitable for applications in the fields of industry and autonomous driving.

    What is AINET-Antillas used for?

    Within AINET-Antillas, data measurements are carried out and sensor modules are evaluated during real measurement runs. In collaboration with network and infrastructure technologies, realistic scenarios can be virtually examined and validated. These scenarios focus on communication and entertainment systems, entertainment functions and autonomous and connected driving functions relying on the 5G mobile communications standard. AINET-Antillas will also contribute to the virtual validation of driver assistance systems, with a particular emphasis on the functions using cellular data to compute their behaviour.

    Our contributions to the project

    KoSi

    The acronym KoSi stands for Cooperative Autonomous Driving with Safety Guarantees. This project aims to investigate how the challenge of autonomous driving in complex traffic situations can be mastered through cooperative manoeuvre planning. Here, a particular focus is on mixed traffic scenarios, i.e. with autonomous and non-autonomous road users.

    Learn more about KoSi

    Goal

    In this project, methods and algorithms are being developed to cooperatively negotiate the areas that can be travelled by the autonomous road user in a group of road users. These areas serve then to plan the vehicle trajectories and to identify potential emergency manoeuvres. Communication models between autonomous and non-autonomous road users are being established for taking into account even mixed traffic scenarios. Prediction of driving behaviour and trajectory planning will be viewed holistically together with their formal verification, thus guaranteeing the safety of manoeuvres. Radar systems as an essential component of autonomous vehicles' sensor technology will be further developed in terms of safety, in particular for detecting attempts at manipulation.

    What is KoSi used for?

    Driver assistance systems have long been an integral part of modern cars and trucks. Despite the development of increasingly intelligent and innovative systems, it is still a rocky road to the safe operation of autonomous vehicles in large-scale use and in all environments (extra-urban and urban). For many years to come, mixed traffic of conventional and automated vehicles, as well as of road users not capable of being automated, will dominate. The development of inherently safe methods of manoeuvre planning, especially for complex traffic scenarios, is thus inevitable. On this issue, KoSi will make its contribution.

    Our contributions to the project

    • Generation of complex, realistic test scenarios (incl. road users not capable of being autonomised, such as cyclists and pedestrians)
    • Method development: coupling of the development and simulation tools involved
    • Verification: validation of the algorithms developed in the project
    • Radar sensor technology: generation of training data, data manipulation

    newAide

    In the newAide project, the partners are researching the use of Artificial Intelligence (AI) methods in highly complex, simulation-based design processes in vehicle development with the aim of accelerating, optimising and partially automating these processes. In addition to improving individual design disciplines through AI approaches, the newAIDE project will use the sub-projects to investigate a fundamental database structure, as well as data structuring that supports and simplifies the use of AI methods in vehicle design. This could provide the base for a widespread introduction of AI approaches in vehicle design and beyond.

    Learn more about newAide

    Goal

    An important technical goal is to optimise simulation processes using AI algorithms. With the help of AI, the simulations will also include boundary conditions and factors in the decision-making process that previously had to be disregarded due to the high complexity. The additional networking is intended to increase the simulations' predictive accuracy and robustness of the simulations and thus contribute to reducing the development time.

    What is newAide used for?

    The project focuses on design processes in which fundamental decisions are based on human knowledge and experience. The decisions are to be learned by AI algorithms and made largely autonomously on the basis of comprehensive test, engineering and simulation data. In this way, complex design tasks that are currently still dependent on the developer's skills and experience can be transferred by AI methods into automatable, data-based decision-making processes.

     

    Our contributions to the project

    • Specifying use cases in multi-body simulation and control systems for the pre-application of chassis parameters.
    • Automating workflows for the chassis and control design process
    • Exploring new methods in metamodelling for physical systems
    • Validating and optimising the methods developed for AI-controlled chassis and control design processes

    ALFRIED

    ALFRIED – Automated and Connected Driving in Logistics at the FRIEDrichshafen test field – is intended to serve inner-city-goods traffic in the future. The overall concept of the hyper-efficient mobility system consists of several mobility users. The project aims to improve the overall traffic situation, especially of vehicles (both connected and non-connected), intelligent infrastructures and control centres. To this end, various technologies are being developed and prepared for use and deployment in real traffic. In the future, the findings from Friedrichshafen should be highly relevant for other cities and regions.

    Learn more about ALFRIED

    Goal

    The aim of the project is to develop a "future-proof, sustainable mobility system through automated driving and networking". As a German medium-sized city, the Friedrichshafen test site (real traffic) on Lake Constance offers an excellent field of application for a mobility concept that is transferable to many cities and regions. With the focus on the infrastructure and the Smart City Control Centre, the complex mobility system of the city of Friedrichshafen is to be further developed. Automated and connected driving, data integration, route optimisation, disruption prediction and intelligent real-time information are to optimise inner-city transport of goods between factory locations. The savings in transport runs and/or the associated emission consumption and the relief of the inner-city traffic volume shall be the outcome of this optimisation.

    What is ALFRIED used for?

    The ALFRIED project addresses problems of road safety and efficiency as well as high road congestion. The mixed operation between motorised and non-motorised road users, as well as among vehicles capable and incapable of V2X, currently poses a challenge. For the benefit of all road users and to reduce traffic hold-ups, there is a need to improve traffic flow and optimise routes.

    Much of the content in the digital platform is expanded by various data sources and evaluated, analysed and displayed via the Smart City Control Centre, including intelligent infrastructure with its sensor fusion concept for complex intersections, as well as automated and connected driving in difficult driving situations. It also includes data from Intelligent Vehicles (about the vehicle, the infrastructure and environment). The results are validated at the Friedrichshafen test field with a special focus on inner-city transport of goods.

    Autoaccept

    Autoaccept stands for the elimination of insecurity in understanding human-machine interaction ("Automation Without Insecurity to Increase Acceptance of Automated and Connected Driving"). To improve the user experience, the recommender system selects the most suitable adaptation for the driver with regard to the information provided on the traffic situation or driving style.

    Learn more about Autoaccept

    Goal

    Lack of trust and negative expectations may diminish acceptance of new technologies. While the emergence of automated and autonomous driving brings many benefits such as more leisure time, users also face challenges. Among the latter are lack of trust, insecurity about driving decisions made autonomously, and motion sickness.

    What is Autoaccept used for?

    To improve the acceptance of automated and autonomous driving, AUTOAKZEPT aims to develop user-centred strategies. This will bring about a safe change in driving style and trust in Human-Machine Interfaces (HMI) in autonomous and automated vehicles. A user-centric, iterative approach is adopted for achieving this. The problems described above are to be overcome by means of Autoaccept.

    LiBAT – Development of a High Voltage Lithium BATtery – aims to develop an ultra-light, highly integrated battery pack for aerospace applications. The LiBAT design meets demanding requirements in terms of weight, energy density and performance and can be used flexibly in various applications. Prior to the LiBAT design being used in electric and hybrid aircraft, prototypical implementations and tests on the ground (TRL4) are being carried out. LiBAT is shaping a new future for aviation.

    Learn more about LiBAT

    Goal

    The field of hybrid and electric propulsion systems for aviation represents an enormous potential for innovation, especially with regard to CO2 savings. In order to achieve reliable, efficient and safe operation of appropriate battery systems, the latter must be developed and optimised with a careful eye on energy capacity, power density, total weight and volume, thermal requirements and design aspects. The main goal of the project is the design of a particularly lightweight battery pack with state-of-the-art energy density and building a prototype. A clear interface definition will ensure the demonstrator's facile integration into current aircraft architectures. The prototype will be developed with the target of achieving TRL4 and will be validated under laboratory conditions.

     

    What is LiBAT used for?

    Lightweight and powerful battery packs can be used in a multitude of ways - from applications in electrified aviation (air taxis, e-gliders) or even in e-vehicles to mobile battery packs (e.g. power provision at construction sites).

    RABE

    Rabe - Intelligent Rollator for Inpatient Care to Preserve the Autonomy of Residents and to Relieve the Workload of Caregivers – comprises the development of an intelligent rollator designed to increase the user's autonomy and mobility while relieving the workload of caregivers. This is achieved through a range of functions, such as the "Autonomous Driving" mode, an indoor navigation and an automatic pedal support. The products developed during the project are being tested in a nursing home run by Stiftung Liebenau.  ollator für die stationäre Pflege zum  Liebenau.       

    Learn more about RABE

    Goal

    The RABE project aims to develop a smart rollator specifically for the needs of long-term inpatient care. The RABE rollator is intended to improve the autonomy of nursing home residents and to relieve nursing staff. This is achieved, among other things, by means of an electric drive that supports the user in coping with longer distances and inclines, as well as in driving over thresholds and curbs. In addition, the rollator is capable of driving autonomously using ultrasonic transmitters and receivers. This allows it, for example, to pick up the user at the bedside, thus relieving him/her of a route on which accidents often occur.

    What is RABE for?

    For years, the number of people in need of care has been rising in Germany due to increasing life expectancy. As a result, there is a growing need for new care concepts for the elderly, which have a demonstrably positive influence on maintaining, restoring or even increasing the quality of life in old age. The resulting needs cannot be met by the nursing staff alone; instead, technological innovations will have to be increasingly integrated into everyday nursing care of the future. The functionalities developed during the RABE project are intended to relieve caregivers of individual tasks or to support them in coping with those.

    Our contributions to the project

    • Supporting the technical implementation of rollator localisation and motor control
    • Implementing indoor navigation
    • Implementing a voice control system
    • Implementing a service-based backend

    OPsTIMAL

    OPsTIMAL – Optimised Processes for Trajectory, Maintenance, Management of Resources and Airline Operations – aims to optimise aviation operations. Data analysis and predictive maintenance of engines help to track the research on these topics.

    Learn more about OPsTIMAL

    Goal

    The OPsTIMAL research project aims at software-based optimisation of flight operations by combining various relevant data sources in a single database. In this way, flexible disruption management, based on current conditions and user preferences such as costs, punctuality and safety, is to be made possible. A key element of the approach is the holistic optimisation of all subsystems considered, i.e. trajectory planning, MRO (Maintenance, Repair and Operations), turnaround and fleet and crew rotation. In the final version, the database display will give users a detailed overview of the respective situation and provide the corresponding evaluated options for action.

This includes the development and adaptation of tools for defining and managing requirements, as well as for creating process plans, equipment models and layouts. For this purpose, a model-based approach is used to define product and production requirements. Tool chain integration focuses on solutions for tool interoperability and plug & play functionality to be flexible in designing the simulation environment. This will have a significant impact on efficiency (cost), quality of models and cycle time for simulations in the industrial context.

    Learn more about AIToC

    Goal

    The aim is to develop an integrated and AI-supported tool chain for production planning and the production systems engineering. The planned tool chain will support the formalisation and automated requirements analysis, the computer-aided simulation model generation and the software-supported generation of layouts. In all these dimensions, AI approaches will be used to process the large amounts of data needed to learn from existing solutions. Concrete methods include knowledge management and expert systems, natural language processing and machine learning.

    What is AIToC used for?

    Expansion and improvement of virtual validation and, in particular, virtual commissioning in production planning and production systems engineering by incorporating manual processing steps and automated model creation for co-simulation.

    Automating and improving the requirements specification process by a) providing a graphical requirements representation for visual analysis, by b) automating the formalisation of natural language text requirements, and by c) providing a formalised and unambiguous basis for analysis, testing, work plan generation and communication during planning and engineering.

    iVeSPA

    iVeSPA – Integrated Verification, Sensors and Positioning for Aircraft Production – is investigating ways to significantly increase the level of digitisation in today's aircraft production. The current level of process step digitisation is rather low. Insofar as the machines used in the process make their sensor data from the undergone process steps available for further use, isolated solutions will emerge at best. A networking of the machines or central storage for simplified access to all data of the manufacturing processes is not widely implemented.

    Learn more about iVeSPA

    Goal

    During the iVeSPA project, the efficiency of aircraft production is to be improved by increasing the individual processes' level of digitisation. For this purpose, radio-based and optical localisation methods are used to track an aircraft component throughout the entire installation process from delivery to installation in the aircraft fuselage. The dataset created is read into a digital 1:1 factory model in real time for simulative process description and display. For value-enhancing integration of sensor data generated with the production, the latter is linked to the underlying processes, thus ensuring quality and temporal sequences of the processes.

    SMART

    “Simulation of mobile networks and automotive behavior in realtime“ - Autonomous driving applications place high demands on mobile communications networks, which naturally have varying qualities of service. SMART is investigating virtual Vehicle-to-X (V2X) applications and their resilience in LTE and 5G scenarios. The project developed a mechanism for negotiating the Quality of Service (QoS). Real-time simulations of V2X-based autonomous driving scenarios in the Tronis® 3D virtual environment were also used to evaluate the mechanism's capabilities to predict stochastic QoS guarantees.

    Learn more about SMART

    Goal

    The aim of SMART is the innovative coupling of existing simulators for sub-aspects of autonomous driving relevant to mobile communications. In this way, a real-time capable simulation platform for the integrated investigation of V2X communications in scenarios close to reality is to be created. Using the platform, the mechanisms developed in SMART for negotiating and predicting the communications' quality of service will be evaluated in terms of their usefulness and feasibility.

    RITUAL

    While assistive robots are already well developed in terms of function, they are currently often not yet capable of interpreting human emotions and behaviour correctly and of interacting with the user in a way appropriate to the situation. If assistive robots are to enter our private everyday life, they must be enabled to correctly interpret the user's state and the context of use and to adapt their verbal and non-verbal interaction strategy accordingly.

    Learn more about RITUAL

    Goal

    In RITUAL, established interaction strategies from robotics and the vehicle cabin are to be integrated into existing assistive robot platforms, adapted to different user types and states and evaluated in a long-term study. The focus is on investigating interaction-relevant parameters, such as the level of proactivity shown by assistive robots when initiating a dialogue with the user, the language of the assistive robots and their approach dynamics. The optimal interaction strategy is determined on the basis of personal characteristics, theoretically substantiated and recorded in the user profile, emotions detected in real time as well as through the interpretation of the current context. By adapting the assistive robot behaviour to both the user and the context, a positive effect on the User Experience (UX), the acceptance and the trust of the user is expected.

    RITUAL is grounded in social science through participatory research methods that iteratively involve potential users in the specification of human-robot interaction (MRI) scenarios and the exploration of ELSI aspects and contextual factors. The special safety requirements arising from the uncontrolled place of use and the proximity between the human and the robot are also taken into account in a safety concept appropriate to both the standards and the context.

    Scientific engineering and physical questions are often formulated by partial differential equations and solved using the Finite Element Method (FEM). In this method, the given calculation domain is first meshed, i.e. broken down into simple geometric elements, such as triangles or quadrilaterals in case of surface models, or tetrahedra or hexahedra in case of volume models. These elements are used as the basis for defining the solution function, the coefficients of which are to be determined by the FE procedure. Depending on the quality of the resulting mesh, this is followed by a mesh optimisation step, which may be integrated, if applicable, into the mesh generation procedure. Then, taking into account boundary conditions such as loads, fixations, etc., a linear system of equations is set up during the FE simulation process to determine the solution coefficients. Subsequently, the resulting FE system is solved using special numerical methods and the solution of the simulation problem is evaluated.

    Starting point: Obtaining high-quality meshes at geometric complexity

    In this process, the quality of the meshing has a decisive influence on the efficiency and accuracy of FE simulation. As a rule, meshes with elements that are as regular as possible are desirable in order to avoid element angles that are too small or too large, since these lead to an increase in the condition number of the stiffness matrix and thus to poorer solvability of the resulting FE system or to inaccuracies in the resulting solution. The generation of high-quality meshes becomes more and more problematic with increasing geometric complexity.

    TWT solution approach: „GETMe“

    TWT's Mathematical Research & Services department developed the Geometric Element Transformation Method (GETMe) for smoothing finite element meshes. In this method, the quality improvement is achieved exclusively by repositioning mesh nodes without changing the mesh topology, i.e. the connectivity structure of the mesh elements is maintained. This is exemplified in the figure below for an outer mesh consisting of hexahedrons of the Aletis open passenger car developed by TWT. In the figure, the elements are coloured according to their regularity. Regularity was measured using a regularity measure, taking the value 0 (red) for degenerated elements and 1 (blue) for regular elements. In particular, elements with small quality numbers should be avoided, as these can lead to instabilities and inaccuracies in the finite element calculation.
     
    Mesh smoothing by GETMe is based on the use of geometric transformations for polygons and polyhedra, which, when applied iteratively, successively transform problematic elements into regular and thus higher-order elements. In principle, the procedure is suitable for the improvement of the most common FE mesh types.

     

    Outcome

    In the publications authored by TWT, it was possible to demonstrate through numerous numerical tests and mathematical proofs that GETMe achieves mesh qualities previously only attainable with global optimisation methods. However, GETMe yields a significant speed advantage, since global optimisation methods require considerably more computing power due to their mathematical optimisation approach.

    Storage MultiApp

    Storage MultiApp will significantly improve the economic performance of stationary industrial storage systems. For this purpose, the operating strategy for "multi-use cases" (self-consumption, peak shaving, etc.) will be optimized, taking lifetime aspects into account, and adapting the hardware to these increased requirements. The operating strategy to be developed is based on a sound understanding of the storage system behavior and its degradation or aging over time. It is precisely these aspects that need to be modeled efficiently and accurately in order to evaluate the impact of "multi-use" applications and to design the lifetime-optimized operating strategy. AI methods will support the characterization and forecasting of services and markets to transfer the defined operation strategy to the low level hardware control.

    Goal

    The MultiApp project aims to significantly improve the profitability of stationary industrial storage systems by enabling new business cases. In this context, the operation strategy for "multi-use cases" (self-consumption, peak shaving, etc.) is to be optimized, taking lifetime aspects into account, and adapting the hardware to these increased requirements. The technical and scientific goals of the project include, among other things, the shortening of development times for lifetime optimized hardware, the establishment of modern battery ageing modelling approaches in industrial applications, as well as the development of suitable solution methods for optimization models of battery storage systems with forecast uncertainty.

    What is Storage MultiApp used for?

    The market for commercial industrial storage systems ("Comercial Storage System" CSS) is a dynamically growing industry. The annual installed capacity in Germany has increased continuously since 2016. Primarily, these systems are used to reduce electricity costs via grid-based services such as peak-shaving or atypical grid use. The reason for this is that peak load capping leads to much faster remuneration than, for example, pure self-consumption optimization in industrial facilities. Thus, profitability can only be achieved in few cases, as investment costs for CSS including installation are currently very high. In addition to grid-based services, the storage system must therefore provide high flexibility to increase reveneu. However, this "multi-use" application means that the storage system will complete several hundred equivalent full cycles on annual average. In addition, the systems are designed to fulfill power peaks with minimal storage capacity or system costs. As a result, CSS are operated at high charging and discharging rates, leading to accelerated cell aging. The aim of the Storage MultiAPP research project is therefore to develop a digital twin that couples modern cell aging models, battery hardware and operational management strategies to enable a long-term aging prognosis for CSS. In this way, aging costs can be planned and optimized via hardware design and operation strategy.

    LONGER

    The acronym Longer stands for "Lifetime-Optimized Intelligent Battery Storage Systems". This project will significantly improve the ecological and economic performance of stationary home energy storage systems. To this end, methods will be developed that individually adjust the charging and discharging strategy of the storage system to the customer's usage behavior and thus optimize self-consumption and extends the service life of the storage system. The approaches to be developed are based on a sound understanding of the storage system behavior and its degradation or aging over time. AI methods will support the characterization and forecasting of services and markets to transfer the defined operation strategy to the low level hardware control. The consideration of economic boundary conditions, such as variable electricity fees, round off the project.

    Goal

    The Longer project aims to significantly improve the ecological and economic performance of stationary home energy storage systems. To this end, this project optimizes the interplay between operating strategy, battery module design and service life in terms of profitability. Methods are being developed to optimize self-consumption and to extend the service life of the storage system by adjusting the charging and discharging rates individually to the customer's usage behavior.

    What is LONGER used for

    A sound understanding of the battery storage system behavior including degradation or aging over time is key for the success of this research project. For this purpose, the interactions of several aspects, such as electro-thermal performance, aging and degradation, operating strategy, as well as economic boundary conditions, must be taken into account. Nevertheless, holistic modeling is numerically expensive and not yet state-of-the-art, especially when covering the entire lifetime of the target systems (>10 years). As part of the research project, a flexible yet high-performant simulation framework will be developed, that efficiently couples different subsystems or "digital twins". With this framework, it will be possible to support the prototypical validation and thus test and evaluate the operation strategy developed in Longer over the entire lifetime of the system. At the end of the project, the results obtained in the context of home storage systems will be analyzed and evaluated in different scenarios as part of a simplified (accelerated) field test.

    PlanQK

    In order to use Quantum Computing efficiently and specifically in real application scenarios, it is essential to have detailed knowledge and experience in dealing with corresponding technologies and concepts. Especially for SMEs it is difficult to get started with Quantum Computing in order to bring new business models and products to the market. While there are many algorithms for quantum computing that can be found on websites, in textbooks and scientific publications, selecting the right algorithm for a specific situation and implementing it on a specific quantum computer requires a comprehensive understanding of the theory and technology. Even when suitable algorithms are found, it is important to turn them into executable programs that add value. This requires deep knowledge of the development environment of the specific quantum computer. Due to the complexity and novelty of these technological trends, there is no easy access to know-how, data, algorithms and experts in these fields. In particular, knowledge sharing via open ecosystems and platforms is lacking. Therefore, the formation of a broad community on a common platform for the exchange of knowledge and technology in the field of quantum computing offers an opportunity to empower industry and especially SMEs to exploit these technology fields and gain access to future key technologies.

    Goal

    The concept of PlanQK aims to develop an open platform and ecosystem for quantum applications. This will create and foster a community of quantum computing specialists, developers of concrete applications, as well as users, customers, service providers and consultants. The PlanQK platform serves as the technical basis for building this quantum computing community. Central components are algorithms, applications and data pools from various sources such as the web, published articles or books. The platform enables these algorithms and data to be distributed and sold through the community. The algorithms and data pools are stored in a special database called PlanQK Algorithm & Data Content Store. The community and the platform operator's specialists can access this database, analyze, clean and unify the algorithms and data. Quality-checked algorithms and data pools are stored in the PlanQK Community Platform. The data pools provide quality assurance and validation by allowing customers and the community to compare different algorithms. Based on the quality-assured algorithms, developers can implement them for execution on a quantum computer. These programs, called Quantum Services, are also quality-assured and stored in the PlanQK Quantum Service Store. Customers can search for algorithms and data in this store and purchase them or use them for free. Similarly, programs implementing such algorithms can be searched for, purchased or used free of charge. If a particular algorithm or data pool is not found or implemented by a program, customers can make requests to the community, service providers, or the platform operator. In case of a purchase, the algorithm, the program and, if applicable, the corresponding data are automatically packaged and transmitted to the quantum computer. Invoicing for the resources used also takes place via the platform.

    MoHAFe

    MoHAFe is researching and demonstrating hybrid working in passenger cars with automation levels 3 to 4, which will become even more attractive and more frequently applicable as a result of the planned new EU regulation permitting automated driving at speeds of up to 130 km/h. The technical-organizational goal is to use the passenger car as a workplace while adapting to the developments towards sustainable mobile work promoted by the covid pandemic. To this end, current results from work science, interface and mobility research will be used to create a demonstrator for working in a (sharing) vehicle, which should potentially also be usable in public transport. Use cases for one or more people in the vehicle including training and education tasks as well as collaboration with spatially remote people, each involved in one or more tasks, will be addressed. VR/AR technologies will be used as needed, with a special focus on user needs in terms of a positive overall experience.

    Learn more about MoHAFe

    Goal

    The project MoHAFe focusses on creating a mobile workplace in the automated vehicle by including and altering the interior of the cockpit and taking interaction possibilities into account. At the same time, the need for an interactive, intelligent, intuitive virtual work environment that meets user requirements comparable to those of a stationary workstation, both in terms of usability and in the processing of confidential information, is accessed.

    What if MoHAFe used for?

    MoHAFe contributes to the very current trends of driving automation and new work. In the process, possibilities for the future-oriented interior design of (partially) autonomous vehicles in the sense of an optional, fully-fledged workplace are being conceived, tested and made tangible. The concepts developed should be relevant to a broad group of people as well as different usage scenarios. The resulting option of performing work activities during business and commuting trips results in more flexible design options for individual work as well as working time.
