20110227759 | Method and System for Ascertaining a Local Information Item for a Vehicle - 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. | 09-22-2011 |
20120252415 | Method For Communicating Between A First Motor Vehicle And At Least One Second Motor Vehicle - A method for communicating between a first motor vehicle and at least one second motor vehicle, belonging to a mobile communication network including at least two motor vehicles. In a first step only one identifying piece of information is exchanged between the vehicles by each driver for forming a communication network by a radio communication unit via radio connection in order to initiate the internal communication of the vehicles present in a column formation, said piece of information being entered in a second step into a network communication unit of each vehicle, in order to join the communication network after acknowledgement by a network communication unit of at least one of the other vehicles belonging to the communication network. The identifying piece of information is an authentication, and the authentication takes place for each vehicle by a randomly generated password. | 10-04-2012 |
20130005292 | Method And Device For Triggering An Emergency Call In A Vehicle Equipped With An Airbag - A method and a device for triggering an emergency call in a vehicle equipped with an airbag. The device can be retrofitted in a vehicle equipped with an airbag to provide an emergency system which, in the event of an airbag being triggered, sends an emergency call (Ecall) to a suitable emergency call center in order to initiate auxiliary measures as may be necessary. | 01-03-2013 |
20130066555 | Method For Transmitting Travel Route Information - A method for transmitting travel route information to a person present outside of a motor vehicle, and to a system for transmitting such information. The method for transmitting travel route information to a person present outside of a motor vehicle provides that a navigation system present in the motor vehicle wirelessly transmits a data stream including the information to be transmitted directly or indirectly to a display device carried by the person. The information to be transmitted can be perceived by the person by the display device. | 03-14-2013 |
20140044212 | Method For Adaptive Channel Estimation For Wireless Communication Between A Vehicle And Other Communication Subscribers Using The Measurement Results Of The Environment Sensor System - Channel estimation for wireless communication between a motor vehicle and another communication subscriber is provided, such that, the result from an environment sensor system is used in the channel estimation. Using the environment sensor system, the propagation behavior of the wireless communication in the vicinity of the motor vehicle is recognized and classified, the channel estimation being adapted on the basis of the classification of the propagation behavior. | 02-13-2014 |
20140050258 | Method For Channel Estimation In Vehicle-To-Environment Communication And Communication Device Arranged Therefor - The invention relates to a method and a correspondingly arranged communication device for channel estimation in vehicle-to-environment communication, wherein a model of the environment influencing the vehicle-to-environment communication is produced from parameters of a vehicle-to-environment communication and the quality of the model for the environment is ascertained by the convergence of the parameters used in the model. The course of the convergence of the parameters in the model is monitored and conclusions are drawn with regard to the environment from the course of the convergence of the parameters. | 02-20-2014 |
20140055288 | Method For Checking Communication Messages In Vehicle-To-Environment Communication And Suitable Receiver - A method for checking communication messages in vehicle-to-environment communication, a communication message being received and evaluated, and to a receiver suitable for carrying out the method. In order to check a communication message, a feature obtained from the content of the communication message is compared to a feature that corresponds to said feature, the corresponding feature being obtained by a sensory system that is independent of the vehicle-to-environment communication. | 02-27-2014 |
20140140353 | Method and communication system for data reception in wireless vehicle-to-surroundings communication - A communication system of a vehicle receives data in wireless vehicle-to-surroundings. The communication system includes multiple control devices. A receiving control device receives data from objects located in the surroundings of the vehicle, and a communication stack is processed during reception. In order for the data to be expediently and effectively acquired, the received data is sorted into at least two classes of relevance and is further processed in the communication stack according to the class of relevance. | 05-22-2014 |
20140140374 | Method And System For Transmitting Data In A Motor Vehicle - A method and a system are provided for transmitting data in a motor vehicle by wireless communication. The data from a first transmitting data node is divided, transmitted to a second receiving data node via at least two different communication routes, and reassembled upon being received. Redundant data is generated from the data to be transmitted, the redundant data allowing a reconstruction of the data to be transmitted in the event that a communication route fails. The redundant data and the data to be transmitted are transmitted via the different communication routes | 05-22-2014 |
20140274182 | Method For Operating A Communication System In Wireless Vehicle-To-Environment Communication, And Communication System - A method for operating a communication system in wireless vehicle-to-environment communication includes: transmitting, using the communication system, different information as signals on various radio channels in accordance with its content, the communication system having at least two reception paths each having at least one separate antenna and an associated separate receiver for receiving the transmitted signals; and changing over the communication system between two modes of operation when a changeover criterion is satisfied, such that the at least two reception paths receive signals on a different radio channel in a first mode of operation and receive signals on the same radio channel in a second mode of operation. | 09-18-2014 |
