The increasing complexity of modern automotive lighting systems requires advanced validation strategies that ensure both functional performance and regulatory compliance. This study presents a structured integration of Software-in-the-Loop (SiL) and Hardware-in-the-Loop (HiL) testing within a digital twin (DT) framework for validating headlamp systems. A gated validation process (G10–G120) is proposed, aligning each development phase with corresponding simulation stages from early requirements and concept validation to real-world scenario testing and continuous integration. A key principle of this approach is the adoption of a framework built upon the V-Cycle, adapted to integrate DT technology with SiL and HiL workflows. This architectural configuration ensures a continuous data flow between the physical system, the digital twin, and embedded software components, enabling real-time feedback, iterative model refinement, and traceable system verification throughout the development lifecycle. The paper also explores strategies for effective DT integration, such as digital twin-as-a-service, which combines virtual testing with physical validation to support earlier fault detection, streamlined simulation workflows, and reduced dependency on physical prototypes during lighting system development. Unlike the existing literature, which often treats SiL, HiL, and DTs in isolation, this work proposes a unified, domain-specific validation framework. The methodology addresses a critical gap by aligning simulation-based testing with development milestones and regulatory standards, offering a foundation for industrial adoption.

Das Lehr-/Lernkonzept Learning by Brewing verknüpft die theoretische Ausbildung in der Automatisierungstechnik mit praxisnaher Anwendung an einer experimentellen Brauanlage. Durch eine enge Verzahnung von Vorlesung und Labor erwerben Studierende nicht nur technische Kompetenzen in Prozessleittechnik, Sensorik und Aktorik, sondern entwickeln auch ihre sozialen Kompetenzen durch Kleingruppenarbeit weiter. Ein zentrales Element ist die Entwicklung, Umsetzung und Validierung eines vollständigen Automatisierungssystems. Die optionale Veranstaltung BRAUtomation erlaubt zudem eine kreative, wettbewerbsbasierte Vertiefung. Das Konzept fördert interdisziplinäres Denken, motiviert durch hohe Praxisnähe und soll zur Steigerung der Attraktivität des Studienschwerpunkts Automatisierungstechnik beitragen.
