With MDSD it can be carried out a significant contribution towards the key factors of success which are exibility and adherence to delivery dates as well as efficient maintenance and adaptability. With AtomsPro that is introduced here we consequently integrate aspects of domain modelling and software architecture as well as clear and understandable means to enable domain experts to take an active role in the software development process. The challenging aim is to increase the overall ratio of code generated in the development process of enterprise applications by at the same time preserving abilities for efficient maintenance. Hence, we have chosen a fruitful cooperation with several involved project partners.

Rund 50% der Kosten für Automatisierungssysteme, welche hier als Plattformtechnologie für RFID gesehen wird, entfallen auf die Software, Tendenz steigend. Außerdem entfallen wie-derum 60% bis sogar 80% im Bereich der hochverfügbaren Softwaresysteme auf das Testen der Software. - Es existieren Methodiken zum Testen von Automatisierungs-, Mechatroniksystemen und zum Testen von reinen Softwareapplikationen. Eine spezielle Testmethodik allerdings, die die Hard- und Software-Spezifika von RFID-Systemen berücksichtigt, existiert nicht. Um den Unsicherheiten beim Testen von RFID-Anwendungen zu begegnen zielte das Forschungsvorhaben ITERA darauf ab, eine neue Methodik für das gezielte Testen derartiger Anwendungen zu entwickeln. Dabei wurde im Projektverbund zunächst untersucht ob eine Integration von existierenden Techniken und Werkzeugen möglich ist und schließlich mit der Entwicklung einer Methodik zur Anwendung von generischen und reproduzierbaren Testszenarios für RFID-Anwendungen begonnen. Die Aufgabe der Technischen Hochschule Ingolstadt bestand im Besonderen darin, die wissenschaftliche Grundlage zu schaffen und anhand dieser eine Me-thodik und ein Konzept zum Testen von RFID Anwendungen zu entwickeln. Die aus dem Gesamtprojekt resultierende Methodik kann grob, wie folgt skizziert werden: - Modultests für Softwarekomponenten, durchgeführt mit Hilfe von vorhandenen Frameworks wie JUnit oder NUnit. - Integrationstest (Bottom-Up) für die verwendeten RFID-Hardwarekomponenten. Dient der Sicherstellung, dass die Funktion der Komponenten und Übertragungswege (Luftschnittstelle) gegeben ist. - Hauptfokus sind Integrationstests (Top-Down), rein für Softwarekomponenten mithilfe der zuvor definierten, virtuellen RFID-Komponenten. Ziel der virtuellen Komponenten ist es, dem Entwickler der Anwendungssoftware ein Mittel an die Hand zu geben, mit dem er Testläufe ohne jegliche RFID-bezogene Hardware ausführen kann. - Systemtest der vollständig aufgesetzten RFID-Systemumgebung. Aus der entwickelnden Methodik entstehen eine Reihe von Vorteilen, wie der frühen Fehler-erkennung, ein effizienterer Testvorgang, die Möglichkeit zur Anwendung agiler Entwick-lungsmethoden, parallelisieren von Testphasen und der Anwendung von bewährten Methoden der Leistungsanalyse und Leistungsverbesserung. Diese Aspekte schlagen sich positiv auf die Softwarequalität, Entwicklungszeit und somit auch auf die Entwicklungskosten nieder.

A1 - Khan, Sarmadullah A1 - Facchi, Christian T1 - Measuring the Realtime Capability of Parallel-Discrete-Event-Simulations JF - Electronics N2 - Speeding up Discrete Event Simulations (DESs) is a broad research field. Promising Parallel Discrete Event Simulation (PDES) approaches with optimistic and conservative synchronisation schemes have emerged throughout the years. However, in the area of real-time simulation, PDESs are rarely considered. This is caused by the complex problem of fitting parallel executed DES models to a real-time clock. Hence, this paper gives an extensive review of existing conservative and optimistic synchronisation schemes for PDESs. It introduces a metric to compare their real-time capabilities to determine whether they can be used for soft or firm real-time simulation. Examples are given on how to apply this metric to evaluate PDESs using synthetic and real-world examples. The results of the investigation reveal that no final answer can be given if PDESs can be used for soft or firm real-time simulation as they are. However, boundary conditions were defined, which allow a use-case specific evaluation of the real-time capabilities of a certain parallel executed DES. Using this in-depth knowledge and can lead to predictability of the real-time behaviour of a simulation run.

How to Form a Good Shape? T2 - Vehits 2024: 10th International Conference on Vehicle Technology and Intelligent Transport Systems Proceedings N2 - Among the possible traffic members on a Vehicle-to-Everything network, the term Vulnerable Road User (VRU) is assigned e.g. to pedestrians and cyclists. The VRU Awareness Message (VAM) is used by VRUs to inform other users of their presence and ensure they are perceived in a traffic system. Since the number of VRUs in crowded areas might be very high, the over-the-air traffic might be overloaded. To reduce channel overload, VAMs offer a clustering feature in which VRUs with similar kinematics and positions can group themselves so that only one device transmits messages. The VRU Basic Service specification describes the cluster as a bounding box that must cover all its members using a geometric shape so that other vehicles in the vicinity can avoid colliding with the contained VRUs. This paper contributes to the standardization effort by introducing a data structure, the Cluster Map, for the clustering in the VRU Basic Service. Furthermore, this work is the first to suggest strategies for forming bounding box shapes. Simulation results show that each of the geometry types is useful in different situations, thus further research on the topic is advised.

This highly accurate vehicle state is usually obtained by means of Inertial Navigation Systems (INSs) that obtain position, velocity, and Course Over Ground (COG) correction data from Satellite Navigation (SatNav). However, SatNav is not always available, as is the case of roofed places, such as parking structures, tunnels, or urban canyons. This leads to a degradation over time of the estimated vehicle state. In the present paper, a methodology is proposed that consists on the use of a Machine Learning (ML)-method (Transformer Neural Network—TNN) with the objective of generating highly accurate velocity correction data from On-Board Diagnostics (OBD) data. The TNN obtains OBD data as input and measurements from state-of-the-art reference sensors as a learning target. The results show that the TNN is able to infer the velocity over ground with a Mean Absolute Error (MAE) of 0.167 kmh (0.046 ms) when a database of 3,428,099 OBD measurements is considered. The accuracy decreases to 0.863 kmh (0.24 ms) when only 5000 OBD measurements are used. Given that the obtained accuracy closely resembles that of state-of-the-art reference sensors, it allows INSs to be provided with accurate velocity correction data. An inference time of less than 40 ms for the generation of new correction data is achieved, which suggests the possibility of online implementation. This supports a highly accurate estimation of the vehicle state for the evaluation and validation of AD and ADAS, even in SatNav-deprived environments.

Based on the current state of the art in research and pre-standardization of V2X communications, we enhance the protocol design for both services and assess their performance by discrete-event simulations in highway and city scenarios. The first part of this chapter addresses the performance improvement of sensor data sharing by two complementary strategies. The shared sensor data are adapted to the available resources on the used channel. Furthermore, the redundancy of the transmitted information is reduced to lower the load on the wireless channel, whereas several approaches are proposed and assessed. The second part of the chapter analyzes cooperative maneuver coordination protocols. We propose a distributed approach based on the explicit exchange of V2X messages, which introduces priorities in maneuver coordination and studies several communication patterns for the negotiation and coordination of maneuvers among two and more vehicles. The results demonstrate the potential of V2X communications for automated driving, showcase several approaches for enhancements of sensor data sharing and maneuver coordination, and indicate the performance of these enhancements.
