Abstract: A method for determining an operating state of a vehicle component of a vehicle. The method includes providing a first knowledge graph that contains information concerning a plurality of vehicle components of a vehicle, each vehicle component providing one or more signals. The method includes determining the operating state of a vehicle component from the plurality of vehicle components, the determining including selecting, using the first knowledge graph, a plurality of signals and one or more state parameters that are necessary for determining the operating state of the vehicle component. The determining further includes calculating one or more state parameters of the vehicle component, based on the selected plurality of signals. The determining of the operating state of the vehicle component includes ascertaining the operating state of the vehicle component based on the information contained in the first knowledge graph and based on the calculated one or more state parameters.

Abstract: A computer-implemented system that includes at least one first interface configured to receive and send data from a physical object, and a graph-based structure. The graph-based structure includes a conceptual model including a plurality of concepts, each concept mapping a physical object, the concepts being provided with attributes and their respective relations among one another being defined, and a plurality of data instances that have data points of physical objects and are assigned to the respective concepts in the conceptual model. The graph-based structure receives data from the interface and integrates received data into the conceptual model and/or into the data instances. A user interface provides a query and/or definition to the graph-based structure based on an input of a user and outputs a corresponding response. The computer-implemented system includes at least one digital twin that draws data from the graph-based structure and/or provides data to the graph-based structure.
