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 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:
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.
摘要:
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.
摘要:
An interface device having a first connection to a vehicle communication unit which is designed to carry out a vehicle-to-environment communication is described, the interface device having a second connection to an infrastructure unit and a computing unit which is designed to convert the signals between the first and second connections. In addition, a vehicle communication unit equipped with the interface device and a use of a vehicle communication unit are described.
摘要:
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.
摘要:
A communication device for a subscriber in a communication network of coequal subscribers, which communication device has a communication unit and a control unit. The received messages are checked for rule compliance. If a message does not comply with a particular rule, a disconnection signal is sent to the transmitter of the message.
