Germany's leading universities in the field of automated vehicles have joined forces with selected specialists from industry in the BMBF funded project UNICARagil to rethink automated vehicles and their architectures. UNICARagil researches disruptive, modular, and agile concepts in hardware and software architecture for fully automated and driverless vehicles. The modular vehicle concept consists of a driving platform and add-on modules, which build the basis for the UNICARagil-vehicles. The UNICARagil-vehicles can be flexibly adapted to a wide range of applications in passenger transport or logistics.

The RWTH Aachen University is involved in the project with the Institute of Automotive Engineering (ika), the Institute and Chair of Flight System Dynamics (FSD) and the Chair of Computer Science 11 - Embedded Software (i11). The i11 is mainly responsible for conceptualization and implementation of a service-oriented software architecture as well as an architecture of cloud-based services.

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) dependability of planned trajectories, (II) real-time compliance of the optimizer on board of 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., to solve the distributed optimization problem on one vehicle while parts of the optimization problems of other road users must be exchanged. In order 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.

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 on novel methods for distributed MPC for reducing the complexity of the planning problem. We verify the resulting trajectories using formal methods.

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. The networked planning is characterized by a receding horizon approach in a 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.

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 own 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.

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 aims 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 surface.

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 a 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 and 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 the road infrastructure.

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

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 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 in order to determine the absolute location of the vehicle. More specifically, Hidden Markov Models (HMM) are used for classification of inputs from acceleration sensors. The project has been implemented using a Pedelec.
