METHOD FOR PROCESSING A VEHICLE-TO-X MESSAGE, METHOD FOR PROCESSING AN ACKNOWLEDGEMENT MESSAGE, AND VEHICLE-TO-X COMMUNICATION MODULE

1 . A method for processing a vehicle-to-X message, the method comprising:

receiving the vehicle-to-X message,

extracting one information item or a plurality of information items from the vehicle-to-X message, and

sending an acknowledgement message containing one or a plurality of the extracted information items.

2 . The method as claimed in claim 1 ,

wherein at least one extracted information item is an extracted location information item,

wherein a unit carrying out the method detects a detected location information item of a sender of the vehicle-to-X message, and

wherein the extracted location information item is compared with the detected location information item.

3 . The method as claimed in claim 2 ,

wherein in response to a deviation between extracted location information item and detected location information item which is at least equal to a threshold value, an error message is output.

4 . The method as claimed in claim 1 ,

wherein at least one extracted information item is an extracted location information item,

wherein depending on the extracted location information item a derived location information item is calculated which represents a location indicated by the extracted location information item in a different representation, and

wherein the acknowledgement message contains the derived location information item of the sender of the vehicle-to-X message.

5 . The method as claimed in claim 1 , wherein the acknowledgement message contains information items from a plurality of received vehicle-to-X messages.

6 . The method as claimed in claim 1 , wherein the acknowledgement message contains timestamps concerning one or a plurality of received vehicle-to-X messages.

7 . The method as claimed in-any claim 1 , wherein the acknowledgement message includes information items relating to a traffic light phase and/or an action recommendation.

8 . The method as claimed in claim 1 , wherein the acknowledgement message includes an information item about whether the sender of the vehicle-to-X message has been detected by a unit carrying out the method.

9 . The method as claimed in claim 1 , wherein the acknowledgement message includes an information item about how many vehicle-to-X messages and/or what vehicle-to-X messages have been received since the last acknowledgement message.

10 . The method as claimed in claim 1 , wherein the vehicle-to-X message is a message that provides vehicle information items of the sender, and/or is a cooperative awareness message or a basic safety message.

11 . The method as claimed in claim 1 , which is carried out by an infrastructure device.

12 . A method for processing an acknowledgement message, the method comprising:

receiving an acknowledgement message containing one information item or a plurality of information items, and

extracting one information item or a plurality of information items from the acknowledgement message.

13 . The method as claimed in claim 12 ,

wherein at least one extracted location information item is extracted from the acknowledgement message, and

wherein the extracted location information item is compared with a detected location information item.

14 . The method as claimed in claim 13 ,

wherein in response to a deviation between extracted location information item and detected location information item which is at least equal to a threshold value, an error message is output, and/or a weighting of information items is changed and/or a vehicle speed is reduced.

15 . A vehicle-to-X communication module configured to carry out a method, the method comprising:

receiving the vehicle-to-X message,

extracting one information item or a plurality of information items from the vehicle-to-X message, and

sending an acknowledgement message containing one or a plurality of the extracted information items.

16 . The method as claimed in claim 2 , wherein in response to a deviation between extracted location information item and detected location information item which is less than the threshold value, a positive message is output.

17 . The method as claimed in claim 2 , wherein the acknowledgement message contains the error message and/or the positive message.
