Abstract: The present invention relates to a motor vehicle that is equipped with an electrical door closing mechanism, a radio-based signal receiver and a control unit, wherein the door closing mechanism can be actuated after receiving and verifying an access authorization code by electrical signals that are generated by a control unit. The motor vehicle possesses an electrical charging apparatus accessible from the outside so that a signal generator that is provided to generate the access code can be charged from the electrical system of the motor vehicle in the event of an insufficient charge. Furthermore, the invention describes a method for charging a signal generator that can be executed using the device according to the invention.

Abstract: Devices, methods and computer programs for establishing a communications link between an information system of a transportation vehicle and a mobile device. The device for an information system of a transportation vehicle for producing a communications link to a mobile device includes a communications module and a control module. The control module controls the communications module, receives information about a hardware address of the mobile device, detects the hardware address of the mobile device via the communications module based on the information about the hardware address, initiates the pairing of the mobile device with the information system based on the hardware address of the mobile device and establishes the communication link to the mobile device based on the pairing.

Abstract: A method, a computer program, and an apparatus for a mobile device for adjusting communication via a mobile communication system. The method includes determining an imminent communication limitation of communication via a mobile communication system based on an anticipated position of the mobile device on a route which is traveled multiple times by the mobile device. The method calculates an anticipated temporal extent of the imminent communication limitation and adjusts the communication via the mobile communication system based on the anticipated temporal extent of the imminent communication limitation.

Abstract: The method simplifies the formation of groups of devices in secure spaces. Such spaces may be passenger compartments of vehicles, and the passenger compartments can additionally be partitioned into zones. Each zone can be allocated a group. For instance, driver and front-seat passenger can be allocated to one group. The travelers in the rear seat-rows can be allocated to another group. This allows data exchange with driver and front-seat passenger that relates to the vehicle route or even relates to vehicle assistance systems. The other group, for instance, children travelling in the vehicle, can share other data, for instance, for entertainment purposes. The acceptance of systems offered in the vehicle can be increased by simple group formation.

Abstract: System and method for detecting an input for an apparatus inside a vehicle, wherein at least one moving user device generates a changing electromagnetic field. A detection unit detects at least one field parameter of the electromagnetic field, wherein the detected field parameter is a function of the geometric arrangement of the user device relative to the detection unit. A radio signature of the user device is determined based on the detected field parameters, and a signature sequence is determined based on a sequence of time-sequentially determined radio signatures of the user device. The determined signature sequence is then assigned to an input gesture, and whereby, based on the input gesture, a signal is generated and output.

Abstract: A method for overriding interference in a reproduced audio signal which is derived from a digital signal, the reproduced audio signal being attenuated as a function of data error statistics of the digital signal, which is distinguished by the fact that a substitute signal is superimposed on the attenuated audio signal as a function of the data error statistics of the digital signal. The method advantageously ensures that, even in the case of very noisy digital input signals, a signal is acoustically reproduced at any time, so that the volume set on an appropriately equipped radio receiver is able to be anticipated realistically for the user at any time. This avoids deceiving the user about the volume of the reproduction that is actually set, which in the case of a very noisy received signal, as a result of the interruption of an audio reproduction, is no longer determinable according to the related art.
