Abstract

Claims (62)

1. Method for sending a vehicle-to-x-message by a sender, wherein the vehicle-to-x-message comprises:

an information part, and

a safety part,

wherein the information part comprises information characterizing the sender and/or data measured and/or calculated by the sender, and

wherein the safety part comprises safety information relating to resistance against technical failures that have not been initiated deliberately of one or more entities of the sender measuring, calculating, transmitting and/or processing the information.

2. The method according to claim 1 ,

wherein the safety part comprises at least one safety level characterizing an entity and/or a provided information grade.

3. The method according to claim 1 ,

wherein the safety part comprises at least one failure rate of a bus system transmitting the information before sending.

4. The method according to claim 1 ,

wherein the safety part comprises at least one indication of a software development process, hardware development process, data generation process, safety engineering standard or processing grade used for developing software of an entity.

5. The method according to claim 1 ,

wherein the safety part comprises a respective predicted validity time for one, some or all information.

6. The method according to claim 5 ,

wherein the validity time is, at least inter alia, calculated based on previous measurements or calculations and/or previous validity values.

7. The method according to claim 1 ,

wherein the safety part comprises at least one indication of an error model of an entity.

8. The method according to claim 1 ,

wherein the safety part comprises at least one confidence, variance, details of an underlying error model of an entity, and/or an absolute or relative validity time of data generated by an entity.

9. The method according to claim 1 ,

wherein the safety part comprises meta-data and/or a multidimensional failure vector.

10. The method according to claim 1 ,

wherein the safety information is continuously updated.

11. The method according to claim 1 ,

wherein the information part comprises one or more of sensor data, speed sensor data, heading data, yaw rate data, acceleration data, curvature data, path history data, radar data, lidar data, steering angle data, position data, camera data, map data, object data, maneuver-related data, intended or planned driving trajectory and/or course data.

12. The method according to claim 1 ,

wherein also vehicle-to-x-messages without a safety part are sent, and

wherein vehicle-to-x-messages including a safety part are only or at least sent in response to one or more pre-defined events and/or automated driving policy or function and/or detected entities near the sender and/or in response to a received request.

13. The method according to claim 1 ,

wherein the information part comprises tolerance bands for one, some or all information.

14. Method for processing a vehicle-to-x-message, the method comprising:

receiving a vehicle-to-x-message comprising an information part and a safety part, wherein the safety part comprises safety information relating to resistance against technical failures that have not been initiated deliberately,

identifying a task and/or function in which the vehicle-to-x-message is relevant,

assessing, based on the safety part and/or the information part, whether information quality or data quality of the vehicle-to-x-message is sufficient for the task, and

performing the task based at least on the vehicle-to-x-message only if the information quality and/or data quality is sufficient.

15. The method according to claim 14 ,

further comprising:

sending a request for further safety data if the data quality and/or safety cannot be determined sufficiently based on the safety data and/or the information.

16. The method according to claim 14 ,

wherein the task is at least one of a lane change, reducing speed and in-lane stopping.

17. Vehicle-to-x-communications module configured to perform the method according to claim 1 .

18. Vehicle-to-x-communications module configured to perform the method according to claim 14 .

19. The method according to claim 15 ,

wherein the task is at least one of a lane change, reducing speed and in-lane stopping.

20. Method for sending a vehicle-to-x message by a sender, wherein the vehicle-to-x message comprises:

an information part, and

a safety part,

wherein the information part comprises information characterizing the sender and/or data measured and/or calculated by the sender, and

wherein the safety part comprises safety information relating to one or more entities of the sender measuring, calculating, transmitting and/or processing the information,

wherein the safety part comprises at least one safety level characterizing an entity and/or a provided information grade;

wherein the safety part comprises at least one failure rate of a bus system transmitting the information before sending;

wherein the safety part comprises at least one indication of a software development process, hardware development process, data generation process, safety engineering standard or processing grade used for developing software of an entity;

wherein the safety part comprises a respective predicted validity time for one, some or all information;

wherein the validity time is, at least inter alia, calculated based on previous measurements or calculations and/or previous validity values;

wherein the safety part comprises at least one indication of an error model of an entity;

wherein the safety part comprises at least one confidence, variance, details of an underlying error model of an entity, and/or an absolute or relative validity time of data generated by an entity;

wherein the safety part comprises meta-data and/or a multidimensional failure vector;

wherein the safety information is continuously updated;

wherein the information part comprises one or more of sensor data, speed sensor data, heading data, yaw rate data, acceleration data, curvature data, path history data, radar data, lidar data, steering angle data, position data, camera data, map data, object data, maneuver-related data, intended or planned driving trajectory and/or course data;

wherein also vehicle-to-x-messages without a safety part are sent, and

wherein vehicle-to-x-messages including a safety part are only or at least sent in response to one or more pre-defined events and/or automated driving policy or function and/or detected entities near the sender and/or in response to a received request; and

wherein the information part comprises tolerance bands for one, some or all information.
