Our research in the field of Cyber-Physical Mobility focuses on the interdisciplinary intersection of control engineering, mathematical optimization, communications, embedded software, and perception. Our research interests include distributed decision-making and verification, service-oriented software architecture, machine learning, and their applications to networked and autonomous vehicles.


We conduct various projects in this research area funded by public organizations and industrial partners. The Cyber-Physical Mobility Lab is our group-wide project that makes our research results tangible, both for the scientific staff and students.

With our research, we contribute to the Future Mobility Center and to the The DFG Research Training Group mobilEM "Integrated Energy Supply Modules for Roadbound E-Mobility" . We thank mobilEM for providing a starting fund. We are also an active member of the Mobility & Transport Engineering profile area.

The DFG priority program CoInCar (Cooperative Interacting Automobiles) gathers an interdisciplinary group of researchers to develop a system-theoretical framework for cooperative traffic involving autonomous automobiles. The program promotes research on several topics including

• Cooperative maneuver and trajectory planning
• Situation prediction
• Cooperative perception
• Data and information base
• System ergonomics
• Cross-cutting issues

We are working on two subprojects of the priority program, namely AutoKnigge and GROKO-Plan. Our subprojects belong to the first research area of cooperative maneuver and trajectory planning. In both subprojects, we focus on distributed decision-making and safety-verification of interacting vehicles while meeting real-time constraints of traffic.


The figure sketches distributed trajectory planning, where two vehicles communicate necessary data so that each vehicle can plan a collision-free trajectory. Major challenges of distributed trajectory planning are (I) the dependability of planned trajectories, (II) real-time compliance of the optimizer on board the vehicles, and (III) a realizable communication effort between vehicles. The first challenge arises since conflict-free trajectories are mandatory. The second challenge is due to high-dimensional non-convex optimization problems, as they occur when many road users must be considered. The third challenge is caused by the interaction, i.e., solving the distributed optimization problem on one vehicle while parts of the optimization problems of other road users must be exchanged. To meet these challenges, we develop novel methods for networked trajectory planning that reduce the computation time and communications requirements while enhancing the feasibility and quality of control.

GROKO-Plan
In the subproject GROKO-Plan (Graph-based, Optimal and Cooperative Trajectory Planning for Interacting Automobiles), we research trajectory planning methods for networked vehicles using graph-based methods with our project partner of the Saarland University. Networked planning is characterized by a receding horizon approach in discrete planning space. Maneuver automata model the dynamics and couplings of agents. We use graph search algorithms and hybrid optimization to find trajectories in the coupled automata. We focus on developing novel methods for distributed computations in order to reduce the complexity of the planning problem.

AutoKnigge
In the subproject AutoKnigge (Modeling, Evaluation, and Verification of Cooperative Interacting Automobiles), we research trajectory planning methods for networked vehicles and methods for safety-verification of the vehicles' motion with our project partners of the Institute for Automotive Engineering (ika) and the Chair of Computer Science 3 - Software Engineering (i3). We plan trajectories using Networked Model Predictive Control (Net-MPC). The planning algorithms use a receding horizon approach in a continuous planning space. The cost function and constraints of the planning problem model the coupling of agents. We research novel methods for distributed MPC for reducing the complexity of the planning problem. We verify the resulting trajectories using formal methods.

The Chair of Computer Science 11 is part of the new Collaborative Research Center / Transregio (SFB/TRR) 339 of the German Research Foundation (DFG). The Collaborative Research Project investigates the “Road of the Future” and is named: »Digital Twin of the Road System - Physical-Informational Representation of Future Road System«.

Research groups from TU Dresden and RWTH Aachen University are researching in collaboration of civil engineering, computer science, and mechanical engineering. The goal of the research area is the creation and exploration of a digital twin of the road system, thus laying the foundation for the analysis and optimization of the future road system. The main focus of this research is the intelligent, gentle, and sustainable use of road infrastructure.

Our task as the Chair of Embedded Software is primarily a sensor data fusion that combines data from different sources. We mainly focus on the inclusion of data from a sensitive road surface layer.

Two German universities and two industrial companies interdisciplinary collaborate in the HarMobi (Harmonizing Mobility) project. HarMobi aims at researching a new basis for evaluating conflicts between different road users. We will use sensor and traffic flow data from bicycles, e-scooters, and cars to determine the behavior of road users and the influence of the road infrastructure. This novel data will be fed into a learning system to better assess safety impacts for future traffic developments and planning.

The predecessor project GefahrstelleRAD investigated the identification of cycling-specific danger spots in public roads for maps and navigation applications, see Gefahrenstellen.

In HarMobi, our group will design the algorithms for data acquisition, critical situation assessment, and map matching. Additionally, we will research conflict causes and create a prognosis model.

Global Navigation Satellite Systems (GNSS), such as GPS or Galileo, can suffer from performance degradation in urban areas, caused by non-line-of-sight or multipath propagation. Therefore, autonomous vehicles additionally use localization algorithms based on heuristic features extracted from sensor data to alleviate the aforementioned problems. While these algorithms tend to perform better in urban areas than GNSS, these approaches have their drawbacks. Even state-of-the-art approaches suffer from issues with long-term stability, scarcity, or ambiguity of the features. This project pursues the development of a low-cost localization system that is aided by infrastructure-based features to overcome the problems of both approaches.

The Chair of Computer Science 11 - Embedded Software (i11) collaborates with the Institute of Automatic Control (IRT, Faculty of Mechanical Engineering) on the new project Service-Oriented Model-based Control (SOMC) funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG). By tightly coupling software engineering and control theory, a service-oriented architecture (SOA) should improve the flexibility and maintainability of control systems. This architecture enables the control system to adapt to situations not foreseen at design time by exchanging control components dynamically at runtime.

The i11 explores an SOA fit for the requirements of real-time, embedded control systems while enabling the necessary flexibility. The IRT develops the required models and investigates stability conditions for switching between control components.

The proposal was submitted by Dr.-Ing. Bassam Alrifaee (head of the Cyber-Physical Mobility Group at i11) and Dr.-Ing. Lorenz Dörschel (IRT). The research associates Ole Greß, M. Sc. (i11) and Markus Zimmer, M. Sc. (IRT) are working on the project.

Leading German universities in the automotive sector and selected researchers from industry jointly research in the AUTOtech.agil project. The goal of AUTOtech.agil is to create an open architecture for the mobility system of the future. A particular focus is on the standardization of interfaces, updatability, and expandability of functional building blocks. Future mobility is electric, networked, and automated. This will lead to a comprehensive transformation of road traffic as we know it today. This is accompanied not only by great opportunities for novel mobility and transportation concepts but also by improvements in road safety and quality of life. This transformation requires agile approaches based on innovative software and hardware architectures that also enable machine learning methods.

In the predecessor project UNICARagil, our Chair was primarily responsible for the design and implementation of the digital architecture. Our chair was in charge of developing the Automotive Service-Oriented Software Architecture (ASOA) and coordinated the realization of the UNICARagil cloud infrastructure.

In AUTOtech.agil, our tasks are

• Researching scalable ASOA
• Enabling service-oriented diagnosis
• Integrating ASOA into industrial platforms and methods
• Creating tools for service-oriented software development
• Collaborating with interdisciplinary project partners

The project eNav aimed at the development of a navigation system for disabled electric wheelchair users. For a selected navigation goal, eNav computes a route that

• avoids inaccessible routes for an electric wheelchair
• avoids uncomfortable routes for the electric wheelchair user
• considers the state of charge of the battery
• offers a multi-modal route by combining rides using the electric wheelchair with rides using public transportation systems.

The system can be transferred to the research of other electric vehicles, e.g., e-bikes. Read more on the project website.

This project pursues the development of a state-of-the-art GNSS/INS, which receives input from a Statistical Absolute Position Estimator (SAPE) for an additional update step. SAPE uses features of the road surface to determine the absolute location of the vehicle. More specifically, Hidden Markov Models (HMM) are used for the classification of inputs from acceleration sensors. The project has been implemented using a Pedelec.

Especially in recent years, the number of bicycles on the road is increasing. In contrast to all other traffic participants, the number of accidents for bicycles is increasing as well. While multiple active safety systems exist for cars, such systems are rare for bicycles and pedelecs. The Bicycle Safety project aimed to develop a low-cost and portable active safety system for bicycles. This system shall warn riders before a potentially dangerous situation occurs. Possible dangerous situations are sharp corners and changing road surfaces.
