Vehicular Communications

There is a cooperation with the automotive industry over several years mainly in terms of joint Ph-D. projects with the Audi AG in the context of the INI.FAU program (http://www.ini.fau.de/) in which we examine a broad range of automotive topics. Example project have been: transmission of safety-relevant data, model-based development of a safety computer, simulation of traffic flow information, security in traffic flow information systems, testing with Markov chain usage models, forecasting of traffic light phases, testing for future safety electronics, concurrency in timed usage models for testing, data quality and control of automotive manufacturing, and evaluation of the benefit from inter-vehicular communication on electric vehicles.

Smart Energy Systems (Smart Grid)

Renewable energy generation is fluctuating, the mismatch between offer and demand can be resolved either by control of conventional power plants, by energy storage or by shifting load peaks on the demand side. The growth of renewables also needs more decentralized coordinated units (e.g. in houses or communities) instead of large centralized ones. For the complete system of merging electrical and communication networks, of various storage technologies and the remaining efficient usage of fossil fuels, simulation models are being developed: on a smaller scale for microgrids (combined producers and consumers which try to remain self-sufficient) and on a larger scale for the main aspects of the energy system of a complete region like a state.

Control of energy systems based on self-learning algorithms

Dynamic simulation of energy flows and storage of waste heat from data centers and of the integration of large storage systems in local heating networks

Excess energy can be stored via heat pumps in low-temperature storage systems and removed via ORC processes. The dimensioning and suitable modes of operation for economic operation are researched by means of dynamic simulation.

Industrial Communications and Sensor Networks

Specialized busses as well as Ethernet are common communication technologies in automation and both need to satisfy specific requirements, e.g., for the latencies of sent messages. Besides simulation models for wireless communications according to IEEE 802.15.4 and ZigBee we use network calculus as an analytic approach for establishing real-time guarantees in wired communications. This is done in a cooperation with the Siemens AG.

Mobile ad-hoc networks (MANETs) solve given tasks cooperatively without a central entity. The task of the infrastructure-less network is to robustly transfer information from the data-source to the data-sink and, if required, mutate it alone the way. Certain scenario-driven requirements, like energy-awareness, must be observed.  In order to maximize availability in unknown networks it is required to continuously update neighboring information. For mobile and battery driven nodes those two features do not go hand in hand and, thus, represent a challenging tradeoff. MANETs are classically located in the 2D domain, utilizing only a limited mobility. Amongst others, we extend the state of the art by pushing MANETs into 3D space were continuous movement is mandatory.

Communication in energy information networks

Test-Driven Agile Simulation

Test-driven agile simulation combines simulation and model-based testing in order to provide mutual benefits for both and in order to define a new approach for systems engineering with improved quality assurance. For this purpose system models and test models with a user perspective (usage models for short) are being developed in parallel and iteratively. The complete approach is based on UML2.

Connected Mobility @ ZOLLHOF

Im Rahmen der Lehrveranstaltung Vernetzte Mobilität und autonomes Fahren haben die Studenten am 24.01.2019 an einem Workshop am Zollhof in Nürnberg teilgenommen. Nach einer regulären Vorlesung in den Räumlichkeiten mit Gründeratmosphäre konnten die Studenten in vier Gruppen eigene Ideen im Bereich der vernetzten Mobilität ausarbeiten. Dabei waren nicht nur technische Möglichkeiten relevant, sondern auch unternehmerische und interdisziplinäre Aspekte. In drei Themenbereichen (sicherheitskritische Anwendungen, Infotainment und routenbasierte Dienste) haben die Teilnehmer mit sehr viel Motivation interessante Ideen entwickeln können und lernten das Vorgehen nach dem Lean Canvas kennen. Ein aktuelles Startup aus dem Mobilitätsbereich (Thema: kostengünstige Parksensoren) hat die eigene Geschichte erzählt und aufgezeigt wie man aus dem studentischen Umfeld erfolgreich eine Idee zum Produkt entwickeln kann. Alle Teilnehmer hatten sehr viel Spass und haben angeregt für zukünftige Teilnehmer der Lehrveranstaltung das Format zu wiederholen.

Simulation-based evaluation of Quality of Service for 5G network mobility

The networking of vehicles with other road users or the infrastructure (Vehicle-to-Everything (V2X)) is one of the key technologies for autonomous driving and smart cities. The next generation of mobile communications (5G), which is going to be launched in 2020, takes into account use cases and criteria for V2X communication from the very beginning and is a key technology for autonomous driving. Foreseen autonomous driving functions need to be able to execute safety-critical applications and infotainment applications simultaneously. In the context of competition for network resources, a 5G network needs to consider these specific Quality of Service requirements and prefer safety applications at any time. The virtualization of mobile radio components (especially the core network) via network slicing is supposed to play a decisive role for the fulfillment of these QoS parameters in 5G. For the evaluation of various driving functions in the 5G context, BMW is cooperating with the Chair of Computer Networks and Communication Systems of the Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) to set up a 5G V2X simulation environment during the upcoming year. The aim is to evaluate the performance as well as the limits of a 5G network with respect to V2X use cases in different realistic traffic scenarios and to investigate them in detail.

Successful coorperation with thyssenkrupp

The Tech-Center Control Technology of the thyssenkrupp AG assigned Computer Science 7 to analyze the optimal dispatch of a cement plant by a combined optimization and simulation model. Mainly cost reduction potentials should be determined by optimizing the cement production considering the integration of storage within the whole production process. Furthermore, a redox-flow batterie and a wind powerplant were added to the cement plant in order to determine possible cost savings by reducing the grid power supply on the one hand and beeing able to offer frequency restoration reserve power on the other hand. The results showed that a significant decrease of electricity supply cost per produced ton cement is possible under certain conditions. For more detailed information please take a look at the paper presented at the Energieinformatik 2016 conference and the article in the technology magazine techforum published by thyssenkrupp AG.
