Vehicle-to-x communication and procedures device

Abstract

A device for vehicle-to-X (V2X) communication, including a computing apparatus for data processing and a generating apparatus for generating vehicle-to-X messages by a protocol stack. The computing apparatus is configured to forecast an anticipated event triggering the broadcasting of a V2X message and to produce data forecast on the basis of the anticipated event and to provide the same to the generating apparatus for generating a forecast vehicle-to-X message. A corresponding method as well as the use of the device in a vehicle is also disclosed.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a device for vehicle-to-X communication, a corresponding method as well as the use of the device in a vehicle.BACKGROUND OF THE INVENTION[0002]Vehicle-to-X (V2X) systems have to meet requirements in respect of a latency time of the broadcast of a V2X message, for example after the occurrence or detection of an event or a change in state of a vehicle. All V2X messages to be broadcast must be signed using a certificate, a so-called pseudonym certificate, such that a receiver of the message can check the authenticity of the sender without the privacy of the sender being affected. The most frequent implementations of corresponding algorithms for signing already require a large part of the overall maximum permitted latency time. Furthermore, the V2X messages are usually signed in order of their planned broadcast, which however in the case of event-based V2X messages can result in extended latency times if one or more V2X messag...

Benefits of technology

The invention aims to provide a way to reduce resource usage while still meeting the necessary latency requirements for transmitting V2X messages. This can lead to cost savings, as many current security units designed for this purpose are not cost-effective for higher volumes of traffic. Additionally, the invention allows for more efficient processing of V2X messages, as it breaks down the sequential processing of these messages to be signed and broadcast. Overall, the invention provides a solution to safely manage V2X traffic while reducing resource usage.

Problems solved by technology

In principle, it is not possible to add message contents of a message to be broadcast, which are intended to be taken into consideration by signing, after signing has taken place.

For a V2X message which does not begin to be generated until an event occurs, it may not be possible to ensure a broadcast within the framework of latency requirements for the smallest possible intended outlay on resources for message processing, in particular signing.
