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

1. 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, wherein the adaptation is carried out on the basis of a correction value, using 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, and

wherein time information for reproducing a duration since an immediately preceding adaptation of the filter parameter and/or counter information for reproducing a number of vehicle-to-X messages since an immediately preceding adaptation of the filter parameter is/are used for ascertaining the correction value.

2. The method according to claim 1 , wherein the correction value is determined, taking account of a rising or falling rate of received vehicle-to-X messages.

3. The method according to claim 2 , wherein a rising rate of received vehicle-to-X messages is taken as a basis if the number of vehicle-to-X messages to be processed has reached or exceeded the number of vehicle-to-X messages provided for processing prior to the expiration of the specified duration.

4. The method according to claim 3 , wherein a falling rate of received vehicle-to-X messages is taken as a basis if the number of vehicle-to-X messages to be processed has not reached or exceeded the number of vehicle-to-X messages provided for processing on reaching or exceeding the specified duration.

5. The method according to claim 2 , wherein a falling rate of received vehicle-to-X messages is taken as a basis if the number of vehicle-to-X messages to be processed has not reached or exceeded the number of vehicle-to-X messages provided for processing on reaching or exceeding the specified duration.

6. The method according to claim 1 , wherein the correction value is taken as a basis for a control method for controlling the number of vehicle-to-X messages to be processed.

7. The method according to claim 1 , wherein the adaptation of the filter parameter is carried out on or following the expiration of the specified duration.

8. The method according to claim 1 , wherein the correction value is arithmetically applied to the filter parameter in order to adapt the filter parameter.

9. The method according to claim 1 , wherein a classification based on the contents of the received vehicle-to-X messages is carried out prior to the filtering of the vehicle-to-X messages.

10. A vehicle-to-X communication device which is configured to execute a method according to claim 1 .

11. A vehicle-to-X communication device comprising a non-transitory computer-readable storage medium which contains program code, when said program code is run by a computing apparatus or by a vehicle-to-X communication device configured to execute a method according to claim 1 .

12. 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, wherein the adaptation is carried out on the basis of a correction value, using 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, and

wherein the correction value is determined, in the event of a rising rate of received vehicle-to-X messages, using a ratio value of the specified duration to a duration up to a time at which the number of vehicle-to-X messages to be processed has reached or exceeded the number provided for processing.

13. 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, wherein the adaptation is carried out on the basis of a correction value, using 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, and

wherein the correction value is determined, in the event of a falling rate of received vehicle-to-X messages, using a ratio value of the number of vehicle-to-X messages to be processed, for which the specified duration has been reached or exceeded, to the number of vehicle-to-X messages provided for processing.
