| 20150019076 | METHOD FOR IDENTIFYING REDUNDANTLY RECEIVED INFORMATION ITEMS, VEHICLE-TO-X COMMUNICATION SYSTEM AND USE OF THE SYSTEM - A method for identifying redundantly received information in which the information is contained in vehicle-to-X messages, one vehicle-to-X message comprising at least one item of information, a plurality of vehicle-to-X messages being received by a receiver, and at least one portion of a total number of items of information being received redundantly. The received items of information are entered into an information table and matched with one another before the received information is processed. | 01-15-2015 |
| 20150019098 | SIGNAL TRANSMITTER, SYSTEM AND METHOD FOR HIGHLIGHTING OBJECTS IN ROAD TRAFFIC, USE OF THE SYSTEM, AND USE OF THE SIGNAL TRANSMITTER - A signal generator for highlighting objects in road traffic, including a marker and a carrier material. The marker is arranged on the carrier material in such a manner that the marker covers one surface side of the carrier material and/or is added to a substance of the carrier material. The signal transmitter reflects incident electromagnetic radiation of at least one predeterminable wavelength band by the marker. A spectral width and a spectral position of the at least one predeterminable wavelength band are distinguished by a size and/or a size distribution and/or a shape of nanoparticles contained in the marker and/or by a surface nanostructuring of the marker. The spectral position of the at least one predeterminable wavelength band is located in an infrared spectral range. The invention further relates to a corresponding system, a corresponding method, the use of the signal generator, and the use of the system. | 01-15-2015 |
| 20150025786 | Method And Device For Determining The Speed And/Or Position Of A Vehicle - A method for determining the speed of a vehicle equipped with at least one surround sensor that determines environment data of the vehicle relative to at least one motionless object includes: receiving, by the vehicle, through wireless vehicle-to-environment communication with the at least one motionless object, a transmitted piece of information about the motionlessness of the motionless object; determining the relative motion of the vehicle with respect to the motionless object from the environment data of the vehicle relative to the motionless object; and determining the speed of the vehicle and/or the relative position of the vehicle with respect to the motionless object from the determined relative motion. | 01-22-2015 |
| 20150065060 | Communication device for a vehicle - A communication device for a vehicle includes: a transmit unit for wireless transmission of vehicle-related data; and a receive unit for receiving vehicle related data. The communication device is configured to be integrated into a lighting unit. | 03-05-2015 |
