摘要： The application relates to an antenna device for transmitting high-frequency signals from or to a motor vehicle. The antenna device comprises a first radio module and a second radio module, which provide high-frequency signals for transmission via an antenna, and an antenna module comprising the antenna and a compensator. The antenna module is connected to the first radio module via a first antenna cable, and to the second radio module via a second antenna cable. The compensator is designed to modify a signal strength of the high-frequency signals in accordance with a control signal. The first radio module and the second radio module are designed to generate the control signal for controlling the compensator, wherein in order to control the compensator, the second radio module modulates the control signal for the first radio module onto the second antenna cable.

摘要： The present disclosure relates to a method for installing a program code packet onto a device. A processor device of the device receives the program code packet via a first data connection from a device-external data source and forms a checksum value in response to the received program code packet. A controller which differs from the processor device is operated in the device. The controller receives a reference checksum value from a specified device-external update server device via a second data connection, which differs from the first data connection, and the checksum value formed by the processor device from same, and a specified installation procedure for installing the program code packet on the processor device is initiated by the controller in the processor device only in the event that the checksum value and the reference checksum value are identical.

摘要： The present disclosure relates to a method for operating an assistance system of a motor vehicle, wherein the assistance system has a projector. A message relating to a wrong-way driver is received, and a position of the wrong-way driver transmitted with the message is compared with a current position. Depending on the comparison, a recommendation for adapting a driving parameter is projected into an area in front of the motor vehicle for the driver by means of the projector. The present disclosure also relates to an assistance system of a motor vehicle and to a motor vehicle.

摘要： An adjustment unit including a bearing having an inner core formed with a passage extending in the longitudinal direction of the inner core. A spacing element is arranged in the passage, which spacing element has an opening for receiving a bearing pin, the opening extends along a longitudinal axis which defines the attachment axis of the bearing, and the attachment axis and the bearing axis are adjustable relative to one another by adjusting the spacing element. The spacing element is movably arranged in the direction of extension of the passage. When the bearing is installed, the spacing element is axially adjusted along the attachment axis and causes a translational deflection of the inner core transversely to the attachment axis.

摘要： The invention relates to a vehicle axle for a motor vehicle. Two wheel carriers, each guided on an axle guide and pivotable by a tie rod, each having a wheel brake. At least one air deflection element per wheel brake, which deflects a travel air flow in the direction of the wheel brake for brake cooling. The air deflection element is fastened on the wheel carrier, on an axle guide, or on the tie rod. A stabilizer for reducing rolling movements of the motor vehicle. The stabilizer includes protective elements arranged in the area of the air deflection elements, which prevent direct striking of the air deflection elements on the stabilizer during steering and/or spring movements.

摘要： A method for operating a fuel tank arrangement for a motor vehicle. The fuel tank arrangement has a fuel tank, a hydrocarbon filter and a pump. The fuel tank is fluidically connected via a tank shut-off valve to the hydrocarbon filter and the hydrocarbon filter is fluidically connected, on the one hand, via the pump to an external environment of the fuel tank arrangement and, on the other hand, via a purge valve to an intake tract of an internal combustion engine. A first leakage test mode is carried out when the pressure in the fuel tank is greater than a pressure threshold value, in which a shut-off valve arranged in terms of flow between the pump and the external environment is closed and the tank shut-off valve is opened.
