Abstract: A steering system includes a steering rod mounted for longitudinal axial sliding in a housing and a steering motor acting on the steering rod via a ball screw drive, for which the steering rod forms a ball recirculation screw thread, which interacts with a transmission nut that can be driven by the steering motor. A transmission wheel of a flexible transmission, by means of which driving power of the steering motor is transmitted to the transmission nut, is untiltably connected to an inner ring of a rotary bearing. The transmission nut is pivotably mounted on the transmission wheel about an arbitrary pivot axis, which is oriented perpendicularly to the longitudinal axis of the steering rod. The transmission nut, which is pivoted as a result of a flexural load on the steering rod, can be decoupled from the rotary bearing and from a tensile load on the transmission wheel.

Abstract: A device and method for determining a knowledge graph. A second embedding is determined for a first embedding for a word including a function. A first classification, which determines whether or not the word is an entity for the knowledge graph, or which defines to which entity or to which type of entity for the knowledge graph the word in the knowledge graph is to be assigned, is determined for the second embedding using a first classifier. A second classification, which defines to which type of embeddings from a plurality of types of embeddings the second embedding is to be assigned, is determined for the second embedding using a second classifier. At least one parameter for the function is trained in a training as a function of a gradient for the training of the first classifier and as a function of a gradient for the training of the second classifier.

Abstract: A method for controlling a vehicle. In the method, data of a digital road map are read in, zones are determined for the digital road map, and possible sequences of trips along a road of the digital road map are ascertained as a function of the determined zones. Furthermore, it is ascertained, as a function of sensor data and/or current driving data of the vehicle, whether a current or predicted traffic situation is outside the possible sequences or corresponds to a possible sequence that is determined as being outside an intended operating range. If the current or predicted traffic situation is outside the possible sequences or corresponds to the possible sequence outside the intended operating range, a measure is determined and the vehicle is controlled as a function of the measure that is taken.
