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. ## Claims ### Claim 1 A communication apparatus for radio key vehicle-to-X communication for a vehicle, said communication apparatus comprising: a radio key device (RKE) having a vehicle module and a portable module; wherein at least one of the vehicle module and the portable module have a transceiver which is designed for wirelessly receiving and sending vehicle-to-X communication data to a further vehicle or an infrastructure. ### Claim 2 (depends on 1) The communication apparatus as claimed in claim 1, also comprising: an interface to a position-finding unit for creating position data for a vehicle. ### Claim 3 (depends on 1) The communication apparatus as claimed in claim 1, wherein the vehicle-to-X communication data are selected from the group consisting of: position data; time stamps; surroundings data; warning signals; identifier data; speed data; direction data; and further information data. ### Claim 4 (depends on 2) The communication apparatus as claimed in claim 2, wherein the vehicle is an emergency vehicle which, after finding an accident scene, sends its position data as a locating signal via the communication apparatus to further emergency vehicles for the purpose of coordinating the operation. ### Claim 5 (depends on 1) The communication apparatus as claimed in claim 1, wherein at least one vehicle also has: a display apparatus which is designed to receive and display vehicle-to-X communication data. ### Claim 6 (depends on 4) The communication apparatus as claimed in claim 4, also comprising a vehicle-based navigation system which is designed to receive the locating signal and to display destination guidance on a digital map on the display apparatus. ### Claim 7 (depends on 1) The communication apparatus as claimed in claim 1, wherein the vehicle-to-X communication data can additionally also be received and transmitted on the basis of a further communication technique with a higher bandwidth from the transceiver on the basis of a standard format, and wherein the further communication technique is selected from the group consisting of: WLAN engineering based on IEEE 802.11 standards; cellular radio based on GSM, UMTS, LTE, Wimax; and communication technique based on DSRC. ### Claim 8 (depends on 7) The communication apparatus as claimed in claim 7, wherein the vehicle-to-X communication data comprise an identifier which indicates what further communication technique is integrated in a transmitter. ### Claim 9 (depends on 1) The communication apparatus as claimed in claim 1, also comprising a memory unit for providing vehicle-to-X communication data. ### Claim 10 (depends on 1) The communication apparatus as claimed in claim 1, also comprising: a microprocessor for processing the vehicle-to-X communication data and for executing communication stacks, wherein the vehicle-to-X communication data have a standard format for an intelligent transportation system (ITS). ### Claim 11 (depends on 1) The communication apparatus as claimed in claim 1, wherein customization of the keyless software can be executed by means of the portable module and/or direct radio communication to the vehicle module. ### Claim 12 (depends on 11) The communication apparatus as claimed in claim 11, wherein a keyless driving authorization has a mid-range or long-range front end. ### Claim 13 (depends on 1) A vehicle having a communication apparatus as claimed in claim 1. ### Claim 14 A method for radio key vehicle-to-X communication with a radio key device, said method comprising: reception of driving authorization data from a portable module associated with keyless driving authorization; and reception and transmission of vehicle-to-X communication data by a transceiver in the radio key device. ### Claim 15 (depends on 14) A program element which, when executed on a microprocessor in a communication apparatus, instructs the microprocessor to perform the method steps as claimed in claim 14. ### Claim 16 (depends on 14) A computer-readable medium which stores a program element which, when executed on a microprocessor in a communication apparatus, instructs the communication apparatus to perform the method steps as claimed in claim 14.
