摘要:
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.

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.
摘要:
External position data, which are transmitted to the vehicle by infrastructural devices or adjacent vehicles, are used for validating or improving the measured vehicle position. As well, these data can be used for calculating the position of the vehicle itself without a satellite navigation receiver having to be provided for this purpose in the vehicle. The position determination can be improved further via a corresponding statistical evaluation.
摘要:
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.
摘要:
Disclosed herein is a communication system for a vehicle for communicating with nearby vehicles which includes a control unit and a communication unit. After a triggering event occurs, an inquiry is sent to nearby vehicles whether a communication voice connection is to be established. Nearby vehicles can thereupon offer the establishment of the voice connection. This establishment can be accepted or rejected by the communication system.
摘要:
A method for the communication of a vehicle with at least one further vehicle and/or for the communication of a vehicle with an infrastructure device (C2X communication), wherein the communication serves to transmit at least one information item for application in a driver assistance system and/or a safety system of the vehicle. In order to ensure good safety and reliability of the driver assistance system or safety system in the case of low market penetration of C2X communication, the at least one information item is transmitted via a first communication channel and/or via a second communication channel in dependence on its nature, wherein the first communication channel has a longer latency period than the second communication channel. The invention also describes a corresponding communication device, a corresponding driver assistance system or a corresponding safety system, a corresponding vehicle, a program element and a computer-readable medium.
摘要:
Methods and an appropriately setup communication unit for positioning in vehicle-to-surroundings communication are described, wherein the method involves a first sensor (S1) of a first communication subscriber using a transmission and reception unit to emit a challenge pulse, to which a transmission and reception unit of a second sensor (S2) of a second communication subscriber responds with a response pulse. The response pulse is received and evaluated by the first sensor (S1) and positioning is performed. In order to achieve reliable cooperative sensor communication, the transmission and reception units of the first and second sensors (S1, S2) use a frequency band (SCH2) which is reserved for vehicle-oriented safety applications.

摘要:
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.
摘要:
According to one exemplary embodiment of the invention, a vehicle antenna apparatus is provided on a vehicle in such a way that this results in the antenna having a horizontal main beam direction. A first reflection apparatus above the conductive roof of the vehicle, with an exciter between these two elements, causes the reflections to be doubled, thus causing the main beam direction to be lowered from a vertical to a horizontal direction.
