Abstract

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.

Claims

1. A method for merging ambient sensor data with communication data, wherein the ambient sensor data are captured by at least one ambient sensor and wherein the communication data are contained in vehicle-to-X messages that are received by vehicle-to-X communication means,

wherein communication data selected by a preprocessing process are supplied directly to a sensor data merging process, wherein the sensor data merging process merges the selected communication data with ambient sensor data to produce an environment model.

2. The method as claimed in claim 1, wherein the selected communication data are provided with a data marking by the preprocessing process.

3. The method as claimed in claim 1, wherein at least one component of the communication data is supplied both to the sensor data merging process and to a data management process by the preprocessing process.

4. The method as claimed in claim 2, wherein heterogeneous application processes that receive information forwarded both by the sensor data merging process and by the data management process identify redundantly forwarded information the data marking.

5. The method as claimed in claim 1, wherein different data formats of received vehicle-to-X messages are standardized in a data arrival process.

6. The method as claimed in claim 5, wherein the communication data are combined to produce a joint data stream by means of the data arrival process and/or the preprocessing process.

7. The method as claimed in claim 5, wherein at least one preprocessing stage, which is affiliated to the data arrival process and an ambient data capture process, is used to effect first filtering of the ambient sensor data and the communication data.

8. The method as claimed in claim 7, wherein the preprocessing process is used to effect second filtering of the communication data.

9. The method as claimed in claim 1, wherein the communication data selected by the preprocessing process are selected on the basis of their header data elements.

10. The method as claimed in claim 7, wherein the preprocessing process and the at least one preprocessing stage are used to categorize the ambient sensor data and the communication data into one of the categories critical, relevant and irrelevant.

11. The method as claimed in claim 10, wherein ambient sensor data and communication data categorized as critical are edited and/or forwarded preferentially.

12. The method as claimed in claim 10, wherein ambient sensor data and communication data categorized as irrelevant are rejected.
