Abstract: A method for charging an electric bicycle from the power supply of a motor vehicle. The motor vehicle is coupled via an electrical trailer connection and an electrical adapter to the battery of the electric bicycle. In order to provide anti-theft protection, the motor vehicle sends the battery a query signal relating to identification data of the battery via a communication channel. Subsequently, the motor vehicle listens in on the communication channel upon transmission of the identification data of the battery. For the case in which the motor vehicle receives incorrect identification data or no identification data from the battery, an alarm signal is output.

Abstract: A method and system for ascertaining at least one traffic-related local information item for a vehicle includes a reception device in a radio system to receive sent data from a radio system in at least one other vehicle in the vicinity of the one vehicle as defined by the reception range of the reception device. The reception device is configured for the vehicle-internal capture and evaluation of data for at least one operating variable from the one vehicle. The traffic-related local information item is ascertained from the received data from the other vehicle.

Abstract: A circuit arrangement for adaptively suppressing interference signals includes a first local oscillator for generating a first local oscillator signal and a second local oscillator for generating a second local oscillator signal, each signal having an adjustable frequency. The circuit arrangement also includes a first mixer for converting a high-frequency signal into a corresponding intermediate frequency signal using the first local oscillator signal and a second mixer for converting the intermediate frequency signal into a corresponding baseband signal using the second local oscillator signal. The circuit arrangement also includes a notch filter with a rigidly defined blocking range.

Abstract: A method for allocating a transmission signal to a transmission channel which has a transmission bandwidth and a rated center frequency and which is established between a radio transmitter and a radio receiver has the steps: emitting the transmission signal on the radio transmitter end with an actual transmitter frequency; receiving the transmission signal in the radio receiver; determining the frequency of the transmission signal in the radio receiver; and deciding on the allocation of the transmission signal to a transmission channel if the frequency determined by the radio receiver lies in a predetermined frequency range.

Abstract: Controller for a motor vehicle for wireless communication with a least one peripheral unit with a least one receiver unit (1) for receiving radio signals for standard applications and at least one receiver unit (2) for receiving radio signals for long-range applications which are emitted by the peripheral unit at different frequencies for the standard applications and the long-range applications. With a least one antenna (ANT1) for one of the two receiver units (1, 2) respectively and with a control unit (4) for controlling the two receiver units (1, 2) as well as for evaluating signals from the two receiver units (1, 2).

Abstract: The invention relates to wireless vehicle-to-X communication by means of radio key (RKE) with a transceiver. The radio key transceiver is designed to send and receive not only data associated with the keyless driving authorization but also vehicle-to-X communication data. The radio key X communication can be used between two vehicles equipped with this radio key communication technique in order to communicate data such as positions, weather conditions or warnings quickly and reliably. This wireless communication technique using radio keys can also be used for coordinating emergency services when searching for an accident scene.

Abstract: A method for exchanging information between a vehicle (1) and a mobile ID provider (11) has the following process steps: transmitting status request signals of the ID provider (11) to a communications device (21) in the vehicle having a prescribed period, wherein the periodically occurring action has the status request signal and a predefined pause, —activating the communications device (21) in the vehicle in case of alarm in a receiving mode, receiving the status request signal of the ID provider (11) by the activated communications device (21) in the vehicle, —transmitting an alarm message by the communications device (21) in the vehicle to the mobile ID provider (11); and display of the alarm signal on the ID provider (11). The method is particularly suited for the display of alarm messages of a vehicle on a mobile ID provider.

Abstract: A device, method, computer program and computer readable medium allowing for vehicle to vehicle and vehicle to infrastructure communication. An ignition key radio technology may used in addition to WLAN-based communication in a vehicle in order to communicate with other vehicles or infrastructure. The ignition key radio technology is used to send only selected data which have been altered significantly. The remaining data are not sent or kept for the WLAN communication.
