Abstract: A vehicle key for radio communication with a vehicle. The vehicle key has a radio transmitter for transmitting radio signals to the vehicle. The vehicle key has a radio receiver and/or audio receiver to be able to locate the vehicle within close range. A bidirectional communication with a transceiver of the vehicle is set up by the radio receiver and/or the audio receiver and the radio transmitter. Furthermore, a corresponding method for locating the vehicle by using the vehicle key is described.

Abstract: A system and method for a navigation system for a complex menu-controlled multifunctional vehicle control system. The system has a navigation unit and a man-machine interface which are arranged separately at different locations in the vehicle. Between the two units there is a communication link which is of bidirectional design.

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.

Abstract: C2X communication is made possible efficiently via WLAN by apparatuses and a method for filtering data frames received by a vehicle from a receiver via a WLAN connection, wherein a frame type indicated in a received data frame is used to decide that device to which data in the data frame are transmitted. The C2X communication can be used for recognizing pedestrians. It is also possible to use a plurality of transmission paths and/or UDP.

Abstract: A communication device, system and method relating to vehicle information being transmitted to other vehicles by virtue of a vehicle using a cellular network to send to a server which then transmits said information via the network to particular, selected vehicles which have a continual communication link to the server. The intervals of time for such transmissions match the dynamics of the relevant events, so that the data traffic can be minimized.

Abstract: A device, system and method for an update system for updating a digital map for a vehicle. The update data is sent from a control center via a satellite navigation system to the individual receivers. The update data is received by the receivers in parallel with the position data from the satellites. For this purpose, a subchannel is provided. This allows large portions of the worldwide population to be supplied with the update data.

Abstract: A method for transmitting vehicle-related information in and out of a vehicle and an apparatus for carrying out the method are disclosed. The method includes the steps of (i) receiving location information via reception means for position finding, (ii) evaluating vehicle-related information and location information via means for coordinating an interaction between the communication means, the reception means and means for wireless radio networking, (iii) transmitting vehicle-related information and the location information to mobile terminals carried in the vehicle by wireless radio networking comprising one bi-directional communication link, and (iv) indicating the vehicle-related information and location information audibly, visually, haptically, or any combination thereof, within a reproduction unit in the mobile terminals.

Abstract: Disclosed is a method for braking or stopping an electromotor which can be operated with direct current, such as a brushless direct current motor. If there is an error in the electromotor or in the electronic or mechanical units connected to the electromotor, the presence of definite error states is verified, and the electromotor is braked, by carrying out, taking into consideration a maximum loading capacity of an electronic control unit which is connected to the electromotor, at least temporarily, a control of the electromotor which is adapted to the detected, definite error state.
