Communication apparatus for vehicle-to-X communication, method and use

A method for vehicle-to-X communication (V2X communication), comprising:

• receiving, via a first interface of a communication apparatus, information in a first vehicle-to-X message, the information configured according to a format of a first wireless communication technology;
• transmitting, via a second interface of the communication apparatus, the received information, the transmitted information configured according to a format of a second wireless communication technology;
• and
• carry out a check by a checking device to establish whether the received information can be confirmed by at least one further information source and, in the event that said information can be confirmed, to add confidence information to a message comprising the information for transmission, which confidence information indicates whether the information has been confirmed by at least one further information source and/or reproduces a confidence measure of the information.

A communication apparatus for vehicle-to-X communication (V2X communication), comprising:

• a first V2X interface for transmitting and/or receiving vehicle-to-X messages by a first wireless communication technology;
• and
• a second V2X interface for transmitting and/or receiving vehicle-to-X messages by a second wireless communication technology,
• wherein the apparatus is configured to:
• receive information in a first vehicle-to-X message via the first interface, the information configured according to a cooperative awareness message (CAM) or a basic safety message (BSM) format of the first wireless communication technology,
• convert, as a function of the message type of the received message, the CAM or the BSM to a collective perception message (CPM) format of the second wireless communication technology, the conversion including:
• identifying objects within the CAM or the BSM have been received by the communication apparatus from other transmitters, and identifying objects within the CAM or the BSM have not been received by the communication apparatus from other transmitters,
• inserting into the CPM, the objects within the CAM or the BSM that have not been received by the communication apparatus from other transmitters,
• excluding from the CPM, the objects within the CAM or the BSM that have been received by the communication apparatus from other transmitters, and
• transmit the CPM in a second vehicle-to-X message via the second interface.
