Abstract: A method for determining a maximum value for a parameter range of a driving operation parameter of a motor vehicle. The motor vehicle includes a control device, at least one electric traction motor, an electric energy storage device which can be operated in an operating temperature range for operating the traction motor, and at least one temperature sensor for determining a temperature of the energy storage device. The control device determines the maximum value as a function of a current temperature of the energy storage device determined by the temperature sensor in such a manner that, after the approach of a destination known to the control device and/or after a journey over a predetermined distance with the driving operation parameter restricted by the maximum value of the parameter range, a predicted temperature of the energy storage device lies within a charging temperature range.

Abstract: The invention present disclosure relates to a method for preventing the voice of at least one person in a vehicle from being intercepted. At least one loudspeaker in the vehicle is activated, wherein the at least one loudspeaker is used to generate audio signals which have at least one frequency that is higher than the threshold frequency for sound that is audible to the at least one person, and the audio signals are used to interfere with the reception of a signal by means of at least one microphone when the at least one person uses their voice to articulate.

Abstract: An example method of providing an at least partially automatic driving function and/or a personalized function in a motor vehicle as well as to the motor vehicle may include establishing a communication link between a communication interface of the motor vehicle and a communication interface of a mobile terminal, which is associated with a user of the motor vehicle; receiving terminal data transferred via the communication link in the motor vehicle, which is recorded on the mobile terminal and which describes at least navigation information and/or user information relating to the user; and providing an at least partially automatic driving function of a driver assistance system of the motor vehicle and/or a personalized function in the motor vehicle by evaluating the received terminal data.

Abstract: The present disclosure relates to a method for simultaneously operating a loudspeaker assembly in a loudspeaker function and in a microphone function. The loudspeaker assembly comprises a coil, which is movably mounted in the magnetic field of a magnet, and a diaphragm, which is mechanically coupled to the coil, wherein the magnet produces a magnetic flux density (B), the coil, has an effective length in the magnetic field, and the diaphragm has an area (A). In order to determine a first transfer function ZM, a first calibration state is set, in which an external sound pressure (p) on the diaphragm is equal to zero. In order to determine a second transfer function ZC, a second calibration state is set, in which movement of the diaphragm is suppressed.

Abstract: The disclosure relates to an active vibration absorption system for absorbing the vibrations of a vibrating element. The vibration absorption system comprises a structure-borne sound exciter having a coupling element for coupling to the vibrating element and having an electrical coil for moving the coupling element by means of a coil current. The structure-borne sound exciter is designed to provide a measurement signal correlated with a detected induced voltage. Furthermore, the vibration absorption system comprises a control device, which is designed to identify a target current intensity of the coil current in accordance with the measurement signal and to control an actual current intensity of the coil current to the target current intensity. The target current intensity is designed to adjust the motion of the coupling element in such a way that the vibrations of the element are at least partly absorbed.
