Abstract: The contactless charging device is designed to provide a charging current for at least one specified energy store in the vehicle in such a manner that a current is transferred from a fixed location primary coil to a secondary coil in the vehicle depending on a magnetic field change generated by the charging device. During a charging phase of the at least one energy store, the invention detects, depending on specified ambient data for a specified environment around the vehicle, whether a vehicle user is approaching the vehicle and/or another vehicle which is located in a specified vicinity of the vehicle with a desire to access the vehicle or the other vehicle. If the invention detects that the vehicle user wishing to access the vehicle is approaching the vehicle and/or the other vehicle, the charging current is reduced in a specified manner.

Abstract: On the basis of a predetermined three-dimensional vehicle environment model and of a second image, acquired at that time, of an image sequence, a corrected display image is determined. The vehicle environment model is determined based on at least a first image of the image sequence and includes an object detected in the first image that has a predetermined resultant absolute position and/or a predetermined resultant position with reference to the vehicle. The second image is acquired a predetermined period of time after the first image and includes the detected object. The corrected display image includes at least one graphic element which represents the detected object and is determined such that it is suitable for being projected onto a display area of the head-up display so as to be perceived by a viewer of the display area from a predetermined viewing position with direct reference to the actual environment of the vehicle.

Further, at least one predefined predictive operating variable for the vehicle is provided. A three-dimensional model for a predefined environment of the vehicle is determined as a function of the route data. A graphic element is determined as a function of the three-dimensional model and of the at least one predictive operating variable. A head-up display of the vehicle has a predefined display field. The graphic element is displayed in the predefined display field. The graphic element is determined and displayed such that the graphic element is perceived by a viewer of the display field from a predefined viewing position with direct reference to the real environment of the vehicle.

Abstract: A method is provided for encrypted radio transmission of data telegrams spaced apart in time in a sequence between a transmitter and a receiver of a system, wherein a key is changeable and is cryptologically derived from a current piece of information. The time elapsed between a preceding telegram and the encrypted telegram implementing the desired data transmission is used as the key. The time span results from a value or entry of a parameter present in the system. The duration in the transmitter and the receiver is determinable from a previously transmitted value or entry of a parameter, or derived only in the transmitter and wirelessly transmitted to the receiver for a future telegram. In a motor vehicle tire pressure monitoring system, the transmitted data originate from a tire sensor and are wirelessly transmitted in an encrypted manner to a vehicle body.

Abstract: The device for operating one or more optical display devices of a vehicle is configured to determine a three-dimensional model for a predefined environment of the vehicle depending on data sets provided and depending on a predefined latency time, wherein the data sets represent predefined vehicle information and/or driving information which is suitable for being signaled graphically and/or pictorially to a vehicle user.

Abstract: A vehicle pneumatic tire has a sealing material on the inside of the tire, which material approximately closes off a leak resulting from damage to the tire. A warning system is provided in a section of the tire having the sealing material. The warning system may be a sensor unit, which monitors the tire air pressure and is secured via an adhesive film to the inside of the tire having the sealing material. The adhesive film is adhered over a large surface area which is larger by an order of magnitude than a base surface of the sensor unit or of a sensor unit securing device. The adhesive film may cover the sensor unit so that it is located between the adhesive film and the inside of the tire.

Abstract: A dataset is determined as a function of a specified navigation information, where the dataset includes a specified metadata structure which is suitable for textually characterizing the navigation information. The dataset is transmitted by way of a specified communication interface. As a function of the dataset received by way of the communication interface, pixel values are determined for at least a portion of pixels of a digital image and/or of a graphic element. Furthermore, a signalization signal is determined for signalizing the pixel values of the pixels by means of the optical display device.
