    Abstract: A rack steering system and a motor vehicle having such a rack steering system. The inventive rack steering system comprises a steering gear housing, a toothed rack, which extends through the steering gear housing, an electric motor, which is coupled to the toothed rack on a thread side of the steering gear housing via a ball screw to provide an axial force to the toothed rack, and two track rod links arranged at axial ends of the toothed rack. The steering gear housing is designed in one piece such that a drive insert opening is formed on the thread side of the steering gear housing for arrangement of the electric motor and a direct stop face for a track rod link or a support face for the arrangement and axial support of a separate stop element for a track rod link is also formed on this thread side.

    Abstract: An air duct device for a vehicle, in particular a motor vehicle, with a tubular air duct having an outer wall that is closed in cross-section, and with at least one elastically deformable latch associated with the air duct. Provision is made that the air duct is designed in at least two parts in cross-section and for this purpose has a first duct element and a second duct element, which are held against one another in a sealing manner by the at least one latch such that together they form the closed outer wall of the air duct.

    Abstract: A method for detecting an adversarial perturbation in input data of a neural network, wherein a conditional generative adversarial network is trained during a training phase, wherein a generator network of the conditional generative adversarial network is trained to generate adversarial perturbations conditioned on input data of the neural network, and wherein a discriminator network of the conditional generative adversarial network is trained at least to detect an adversarial perturbation in the input data generated by the generator network, and wherein, during an application phase, the trained discriminator network detects an adversarial perturbation in input data of the neural network and provides a detection result. Also disclosed is a backend server, a detection device and a system.

    Abstract: A method for controlling an electric machine using measurement coils arranged in an air gap situated between a stator and a rotor of the electric machine, a plurality of phase windings assigned to different electrical phases being present. Magnetic linkage fluxes are measured in the air gap via the measurement coils, Magnetic linkage fluxes are determined of the plurality of phase windings of the different phases. The determined magnetic linkage fluxes are transformed into a stator-fixed orthogonal coordinate system in order to obtain orthogonal magnetic linkage fluxes. Phase currents flowing through the plurality of phase windings are measured. The measured phase currents are transformed into the stator-fixed orthogonal coordinate system in order to obtain orthogonal phase currents. An instantaneous torque and/or a flux-forming component of a phase current vector are ascertained. The electric machine is controlled based on the instantaneous torque and/or the flux-forming component.
