Abstract

A method captures data and transfers the data from a transmitter to a receiver, which is a transportation vehicle, and controls the capture and transfer of data. The method produces data and transfers the data from a transmitter to a receiver, which is a traffic participant. The data are based on a geographic environment model of the transmitter, wherein the geographic environment model includes a recognition of objects. Operations at the transmitter include capturing parameters of a transfer system for transferring the data and/or traffic-relevant parameters of the transmitter, producing the data in accordance with the recognized objects, and transferring the data in accordance with the parameters of the transfer system and/or the traffic-relevant parameters of the transmitter.

Claims

1. A method for generating and transferring data from a transmitter to a receiver, which is a road user, the method comprising:

capturing parameters of a transmission system to be used for transferring the data and capturing traffic-relevant parameters in a geographical environment of the transmitter, wherein capturing the traffic-relevant parameters includes analyzing, using a geographical environment model, the geographical environment for objects relevant to the road user;

generating data based on the captured traffic-relevant parameters; and

transferring the generated data from the transmitter to the road user, based on the parameters of the transmission system, wherein the road user is an emergency vehicle, wherein transferring of the data alters from a periodic transferring, that occurs in response to an expiration of a regular time interval, to an aperiodic transferring, that occurs in response to a change in the object relevant to the emergency vehicle, and wherein the periodic transferring includes delaying transferring the data until the expiration of the regular time interval without the object relevant to the emergency vehicle having been detected thereby indicating that relevant objects have not been detected.

2. The method of claim 1, wherein the traffic-relevant parameters comprise data relating to the description of at least the transmitter, which is a transportation vehicle, and/or a traffic conditions and/or a road layout.

3. The method of claim 2, wherein the parameters of the transmission system comprise a channel capacity of the channel for the data transfer and/or an availability of the at least one receiver and/or the presence of a message with a higher priority.

4. The method of claim 2, wherein the channel capacity and/or the traffic-relevant parameters influence the frequency at which the data are transferred.

5. The method of claim 1, wherein the channel for the data transfer is also used to transfer general attention messages and/or decentralized environment messages.

6. The method of claim 1, wherein the channel for the data transfer is designed according to a standardized reference architecture.

7. The method of claim 1, wherein the transmitter is an additional road user or infrastructure.

8. The method of claim 1, wherein transmitter and/or receiver are transportation vehicles.

9. The method of claim 1, wherein the geographical environment model of the transmitter comprises an object recognition based on local sensor data of the transmitter and/or based on sensor data of other road users or infrastructure.

10. The method of claim 9, wherein the object recognition comprises data for a probability of existence of the object and/or for change information of the object, wherein the change information for the object describe temporal and/or spatial changes.

11. The method of claim 1, wherein generating of the data is in response to at least one of:

an object being recognized with an overwhelming probability of existence;

or

an object having exceeded a change measure;

or

an object recognized with an overwhelming probability of existence having exceeded the change measure.

12. The method of claim 1, wherein the data in a data field are transmitted via a mobile network, the data field comprising:

a header field with general information and the message and transportation vehicle/infrastructure identification; and

/or

a description field, which comprises an identification of the transportation vehicle and/or a position of the transportation vehicle and/or a distance to the transportation vehicle and/or a speed of the transportation vehicle and/or an acceleration of the transportation vehicle and/or at least one property of the local sensors of the transportation vehicle; and

/or

a dynamic object container, which comprises the description of at least one dynamic object; and

/or

a static object container, which comprises the description of at least one static object.

13. A device for generating and transferring data, the device comprising:

a generation processor for analyzing, using a geographical environment model, a geographic environment of the device for objects relevant to a road user;

a capture processor for capturing parameters of a transmission system to be used for transferring the;

a data generation processor for generating the data based on the analysis of the geographic environment of the device for the objects relevant to the road user; and

a transmission device for transferring the generated data based on the parameters of the transmission system and/or depending on the traffic-relevant parameters to the road user, wherein the road user is an emergency vehicle,

wherein the transmission device alters from transferring the data using a periodic transferring, that occurs in response to an expiration of a regular time interval, to transferring the data using an aperiodic transferring, that occurs in response to a change in the object relevant to the emergency vehicle, and

wherein the periodic transferring includes delaying transferring the data until the expiration of the regular time interval without the object relevant to the emergency vehicle having been detected thereby indicating that relevant objects have not been detected.

14. The device of claim 13, wherein the device is a transportation vehicle or as a transport infrastructure building.

15. The device of claim 13, wherein the data generation processor generates data in response to at least one of:

the detected object being recognized with an overwhelming probability of existence, the detected object having exceeded a change measure, and the detected object recognized with an overwhelming probability of existence having exceeded the change measure.

16. A non-transitory computer-readable storage medium including instructions for carrying out a method for generating and transferring data from a transmitter to a receiver, which is a road user, the method comprising:

capturing parameters of a transmission system to be used to transfer data and capturing traffic-relevant parameters in a geographic environment of the transmitter, wherein capturing the traffic-relevant parameters includes analyzing, using a geographical environment model, the geographical environment for objects relevant to the road user;

generating data based on the captured traffic-relevant parameters; and

transferring to the road user the generated data based on the parameters of the transmission system,

wherein the road user is an emergency vehicle,

wherein transferring of the data alters from a periodic transferring, that occurs in response to an expiration of a regular time interval, to an aperiodic transferring, that occurs in response to a change in the object relevant to the emergency vehicle, and

wherein the periodic transferring includes delaying transferring the data until the expiration of the regular time interval without the object relevant to the emergency vehicle having been detected thereby indicating that relevant objects have not been detected.

17. The method of claim 16, wherein generating of the data is in response to at least one of:

the object being recognized with an overwhelming probability of existence, the object having exceeded a change measure, and the object recognized with an overwhelming probability of existence having exceed the change measure.
