André Ebel wertet Flottendaten eines batterieelektrischen Fahrzeuges hinsichtlich Fehlerbedingungen aus und generiert daraus unter Verwendung einer Gesamtfahrzeugsimulationsumgebung repräsentative Prüfzyklen zur zeitlichen Rekonstruktion der Fehlerbedingungen. Anhand der Flottendatenauswertung mit Methoden des Maschinellen Lernens identifiziert der Autor das schädigende Nutzungsverhalten fehlerhafter Fahrzeuge. Zur Generierung von kundennahen Prüfzyklen setzt er das tiefe Q-Lernen ein, ein Verfahren des bestärkenden Lernens. Die Kombination der Flottendatenauswertung mit der Prüfzyklengenerierung trägt zur zielgerichteten und realitätsnahen Erprobung von Antriebssträngen bei.

In zwei Probandenstudien hat Christoph Johannes Heimsath eine signifikante Verbesserung des Komforts für Kfz-Passagiere durch den gezielten Einsatz von asymmetrischen Trajektorien nachgewiesen. Er kann zeigen, dass sich Kurven negativ auf die Komforthomogenität innerhalb eines Spurwechsels auswirken. Dieser Effekt kann gezielt durch die Wahl einer asymmetrischen Trajektorie kompensiert und damit der Gesamtkomfort verbessert werden. Dies ermöglicht eine Akzeptanzverbesserung für die Assistenzsysteme künftiger Serienfahrzeuge. Die entwickelte Methode ist ein wesentlicher Baustein für die weitere Objektivierung von hochautomatisierten Fahrfunktionen.

Andreas Heinz führt im Fahrzeugumfeld erstmalig ein Verfahren ein, um ein Messvorhaben mittels ereignisorientierter Datenübertragung zu konzipieren und dessen Durchführbarkeit abzuschätzen. Darüber hinaus zeigt er, wie Messungen effizienter gestaltet bzw. qualitativ hinsichtlich Auflösung und Zeitverhalten optimiert werden können. Dabei werden gegebene Sicherheitsanforderungen und normative Vorgaben stets eingehalten und eine Buslastberechnung für den CAN eingeführt, die zusätzliche Buslasten für Messzwecke berücksichtigen kann. Dies ermöglicht dem Autor, im Vorfeld der Messung eine Aussage treffen zu können, ob diese Messaufgabe für einen sicheren Einsatz im realen Fahrbetrieb realisierbar ist oder nicht.

Lorenz Georg Görne presents a method (PrOComp) for optimal usage of the transmission path between the vehicle and the data backend. The compression ratio of vehicle measurement data could be improved from roughly a factor of ten in conventional methods, to up to 27. The method allows vehicle measurement data to be transmitted optimally in terms of data volume via the mobile internet and via traditional transmission routes. Through the PrOComp method, real-time data analysis over the mobile internet is feasible, as well as the collection of big data in the field. This enables key features like predictive maintenance, reactive event evaluation (for example crash events) or fast generation of AI training data. Through the usage of standardized interfaces and data formats, PrOComp can be adapted to the needs of many industry branches that feature field data collection.

Kordian Adam Komarek stellt einen neuen grundlegenden Ansatz vor, die Qualität von diagnostischen Messdaten in verteilten Systemen signifikant zu erhöhen. Kern dieses Verfahrens ist eine neue Methode, strukturelle und inhaltlichen Ähnlichkeiten von heterogenen Fahrzeugdiagnosedaten (ODX) inkrementell zu clustern (XCXS ¿ XML document clustering with XEdge and weighted structure and content similarity). Am Beispiel eines prototypischen Remote-Diagnosesystems, mit dem Fokus auf die Fahrzeugentwicklung, werden diagnostische Fehler erstmalig identifizierbar gemacht.

Die Nutzung der Driver-in-the-Loop-Simulation zur virtuellen Entwicklung und Erprobung erfordert ein Software-Framework. Dieses muss zum einen die Erzielung repräsentativer Ergebnisse erlauben und zum anderen die Integration sowohl von Konzeptideen als auch prototypischer oder bestehender Systeme zulassen. Martin Kehrer weist für das Framework eine Simulationsgüte nach, die eine ausreichende Immersion des Fahrers erzielt. Maßgeblich hierfür ist die sogenannte Simulator Sickness, welche ein Index für eine mangelnde Immersion ist. Daneben bedingt die Erprobung neuer Fahrzeugsysteme die Bereitstellung einer ausreichenden Menge an Umgebungsdaten.

Antriebsstrangprüfstände leisten einen signifikanten Beitrag im Fahrzeugentwicklungsprozess. Um diesen Vorteil weiter auszubauen, ist es notwendig, mit geeigneten Maßnahmen die Effektivität und Effizienz stetig zu steigern. Eine Maßnahme ist hierbei, die Abhängigkeit des Faktors Mensch bei Auftreten eines Fehlers am Prüfstand zu reduzieren. Um diesem Ziel einen großen Schritt näher zu kommen, wurde vorliegend eine KI-basierte Methodik entwickelt, mit deren Hilfe es möglich ist, die fehlerverursachende Komponente und den zugehörigen Fehlerzeitpunkt trotz der Wechselwirkung aufgrund der mechanischen Kopplung des Systems zu detektieren.

Im Aufbau startet diese Dissertation zunächst mit Begriffsdefinitionen zum detaillierteren Verständnis der Schwachstellenanalytik. Im weiteren Verlauf wird eine Struktur betrieblicher Schwachstellen erarbeitet, ergänzt durch einen entsprechenden Kennzahlenkatalog sowie Methodenkatalog. Dabei wird ein erhebliches Mengengerüst erkennbar: Die Erarbeitung einer grundlegenden Struktur betrieblicher Schwach­stellen zeigt einen Schwachstellenkatalog mit 297 potenziellen Schwachstellen, der Kennzahlenkatalog beinhaltet 264 bekannte Kennzahlen und der Methodenkatalog enthält 551 verschiedene Methoden. Die Erforschung und Evaluation der Schwachstellenanalytik erfolgte anhand eines exemplarischen Stanzkontaktes. Die grundlegende Prozessfähigkeit wurde bestätigt. Anschließend wurden gezielt Korrelationen untersucht und eine Ampelprognose entwickelt. Die Verifizierung erfolgte mittels eines erneuten Datensets desselben Produktes. Die Schwachstellenanalytik wurde in ihren Grundzügen mathematisch formuliert. Die Erprobung anhand eines Montage-Prozesses bestätigte die Reproduzierbarkeit und Funktionalität der Schwachstellenanalytik. Letztlich können erhebliche Produktivitätspotenziale belegt und so der Mehrwert der Schwachstellenanalytik zur Modell­verfeinerung von Machine Learning in Fertigungsbereichen bestätigt werden.
