Abstract: A screwable vehicle antenna has a threaded part and a head part, which adjoins an end region of the threaded part. The threaded part and the head part both are made of electrically non-conductive material. At least one antenna radiator is arranged at least within part of the head part. A metal disk made of electrically conductive material is arranged on the head part and is used as a reflector or a ground plane. An HF electrical connector is provided, which is arranged on and fastened to a region of the head part remote from the threaded part, and the antenna radiator can be electrically connected to a plug of the HF electrical connector.

Abstract: A controller for a vehicle includes a main control unit, at least one first secondary control unit, and a switching device. The main control unit is configured to execute processes of critical or safety-related applications. The at least one first secondary control unit is configured execute agile applications. The switching device is configured to deactivate the at least one secondary control unit. The main control unit is also configured, in the event of the occurrence of a predefined safety-related event, to deactivate the at least one secondary control unit by means of the switching device.

Abstract: A method transmits a data element between control units of a vehicle that are coupled via at least two communication channels. The first control unit determines a communication channel indicator of a first channel that is representative of available transmission resources. The first control unit receives a data element from a data source. The priority of the data element is ascertained depending on an associated vehicle application. If the communication channel indicator indicates that the available transmission resources of the first channel are insufficient for transmission of the data element and the priority of the data element is less than a predefined priority threshold value, then storing the data element in a temporary memory of the first control unit for a predefined time interval. In a different case, the data element is transmitted from the first control unit to the second control unit via assigned communication channel(s)..

Abstract: A telematics device includes a housing, and first and second circuit boards. An electronic control unit of the telematics device is arranged on the first circuit board. At least one antenna of the telematics device is arranged on the second circuit board. The first circuit board and the second circuit board are arranged together in the housing. The first circuit board and the second circuit board are coupled by means of at least one electrical connecting element.

Abstract: A transceiver for a vehicle for communication in a mobile radio system includes one or more interfaces for a plurality of antennas, and a transceiving device configured to communicate via the one or more interfaces and via at least a part of the plurality of antennas in the mobile radio system. The transceiver also includes a control device configured to control the transceiving device and the one or more interfaces, where the control device determines, via a first cluster of the plurality of antennas, information about a radio channel between the first cluster of antennas and a base station of the mobile radio system, and communicates via a second cluster of the plurality of antennas with the base station of the mobile radio system.

Abstract: A communication method (S) for communication between mobile units (10, 20), and in particular between vehicles, in which information transmitted between the mobile units (10, 20) is encoded on the transmitter side by means of an encoder (12-1, 22-1) and is decoded on the receiver side by means of a decoder (12-2, 22-2), and the mobile units (10, 20) are synchronized in communication (S3) with an external interface unit (30) outside the mobile units (10, 20) prior to communication (S5) with one another in that a codebook (Cj) defining or specifying an encoder (12-1, 22-1) and/or a decoder (12-2, 22-2) is determined (S2) by the external interface unit (30) and is communicated (S3) to the mobile units (10, 20).
