Disclosed is a method for sending a vehicle-to-x-message including an information part and a safety part, wherein the safety part comprises information that can be used to evaluate quality and reliability of the information contained in the information part regarding its usability and qualification for safety-related driving functions and tasks. Also disclosed is a corresponding method for receiving and a corresponding vehicle-to-x-communications module.

Method for sending a vehicle-to-x message by a sender, method for processing a vehicle-to-x-message, and a vehicle-to-x-communications module

A method for filtering vehicle-to-X messages, having the following steps: receiving a number of vehicle-to-X messages and adapting a filter parameter for filtering the received vehicle-to-X messages in such a manner that a number of vehicle-to-X messages to be discarded leaves a number of vehicle-to-X messages to be processed from the number of received vehicle-to-X messages. The adaptation is carried out on the basis of a correction value for describing a deviation of the number of vehicle-to-X messages to be processed in a specified duration from a number of vehicle-to-X messages provided for processing in the specified duration. Also disclosed are a corresponding vehicle-to-X communication device and to a computer-readable storage medium.

Method for filtering vehicle-to-X messages, vehicle-to-X communication device, and computer-readable storage medium

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.

A method for updating an electronic card in a vehicle based on a deviation between predicted states and actual states comprises calculating a predicted state of the vehicle, establishing an actual state of the vehicle, determining a deviation between the predicted state and the actual state, and storing information in the map if the predicted state and the actual state deviate from one another.

Method for updating an electronic card of a vehicle

A method for determining a channel load in a vehicle-to-X communication, a method for adjusting a preprocessing in a vehicle-to-X communication, a vehicle-to-X communication system and a storage medium. In particular, a preprocessing can be adjusted in a vehicle-to-X communication, for example a filtering out of vehicle-to-X messages, to the channel load and/or to a system power by the method according to the invention.

The disclosure relates to a method for generating a time stamp in a vehicle which participates in a vehicle ad-hoc network. The method includes associating, by giving out the time stamp, an event, which is transmitted in a message, with a clock time. The clock time is generated by updating a global time base that may be derived from a global satellite navigation signal (GNSS). The method includes checking whether a GNSS signal may be received. The method also includes generating the clock time based on a local time base if an insufficient number of global satellite navigation signals for deriving the global time base is available.

Time stamp generation without GNSS signal

A method for processing vehicle-to-X messages in a processing module and a method for processing vehicle-to-X messages in a control module. In the course of this messages are checked in a specified checking sequence.

Method for processing vehicle-to-X messages

A method for processing vehicle-to-x messages in a processing module and a method for processing vehicle-to-x messages in a control module. In this way, the data traffic between processing module and control module can be considerably reduced.

Method for processing vehicle-to-x messages

The invention relates to a method for handling a received vehicle-to-X message in a vehicle, said message having at least a header and a body, and only the header without the body being forwarded to a self-learning map, in particular if it is established that the message is suitable for simplified processing. The invention also relates to a vehicle-to-X communications module and a storage medium for carrying out the method.

Method for handling a received vehicle-to-X message in a vehicle, vehicle-to-X communications module and storage medium

A method for filtering a message transmitted between a transmitter and a receiver in a vehicular ad hoc network, the message containing at least one position of the transmitter, including: determining a position of the receiver by a global satellite navigation system in a predetermined coordinate system; determining a decision threshold for a maximum distance between the receiver and the transmitter in the predetermined coordinate system in which the position of the receiver was determined; and discarding the message if a distance between the position of the transmitter and the position of the receiver exceeds the decision threshold.

CAR2X receiver filtering based on a receiving corridor in a geographic coordinate system

A method for receiving a data packet containing at least position data in a transmission signal via a vehicular ad hoc network, including: filtering the received data packet on the basis of a first filter condition and outputting the filtered data packet to a processing device for processing the filtered data packet; and filtering the received data packet on the basis of a second filter condition and outputting the filtered data packet to a forwarding device for forwarding the filtered data packet to another subscriber of the vehicular ad hoc network.

Processing-path-dependent filtering of data packets received in the car2X network

A communication system for a vehicle, with a processor designed to determine a driving situation of the vehicle, and a communication interface designed to receive V2X communication data of a first additional vehicle, wherein the V2X communication data defines a driving situation of the first additional vehicle, wherein the processor is designed to detect a second additional vehicle which is located between the vehicle and the first additional vehicle on the basis of the determined driving situation of the vehicle and the driving situation of the first additional vehicle.

Communication system for a vehicle

A method for merging environment sensor data with communication data, wherein the environment sensor data is detected by at least one environment sensor and wherein the communication data is contained in vehicle-to-X messages which are received by vehicle-to-X communication. The communication data selected by pre-processing is fed directly to the sensor data merging process, wherein the sensor data merging process merges the selected communication data with environment sensor data to form an environment model. A corresponding system and a usage of the system are also disclosed.

A method and system for the distributed transmission of the communication flow, in which the communication flow takes place at least unidirectionally from a first to a second communication unit and wherein the first and second communication units are capable of transmitting the communication flow by means of at least two different communication paths, the communication flow comprises at least one vehicle-to-X message. The communication flow is divided into at least two communication flow elements by the first communication unit prior to sending, wherein the at least two communication flow elements are transmitted from the first to the second communication unit in a manner distributed over the at least two different communication paths, and wherein the at least two communication flow elements are assembled again by the second communication unit following reception.

A filter method for adapting a computing load to a computing capacity of a car-to-x communication system, in which method car-to-x messages are received and/or sent using the car-to-x communication system and the received car-to-x messages require processing by the car-to-x communication system. The filter method decides which of the received car-to-x messages to process and which of the received car-to-x messages to discard.
