Abstract

A method and a transportation vehicle communication system for determining a driving intention for a transportation vehicle. The driving intention includes information about a predicted driving maneuver. The method includes determining a position of the transportation vehicle; identifying a road section based on the position of the transportation vehicle and a digital map; obtaining information about internal trigger variables for determining a current driving intention based on on-board sensors or actuators of the transportation vehicle; and determining the driving intention based on the road section, the information about the internal trigger variables, and the one or more trigger conditions. One or more possible driving intentions are associated with the road section. One or more trigger conditions are associated with the one or more possible driving intentions based on one or more trigger variables.

Claims

1. A method for determining a driving intention for a transportation vehicle, wherein the driving intention comprises information about a predicted driving maneuver, the method comprising:

determining a position of the transportation vehicle;

identifying a section of road based on the position of the transportation vehicle and a digital map;

assigning two or more possible driving intentions to the identified section of road;

obtaining information about internal trigger variables based on on-board sensors or actuators of the transportation vehicle;

assigning one or more triggering conditions to the two or more possible driving intentions and assigning probability of intention to each of the one or more trigger conditions if met; and

determining the driving intention based on the identified section of road, the information about the internal trigger variables and the one or more triggering conditions.

2. The method of claim 1, further comprising making available a driving intention message via a vehicle-to-vehicle interface for one or more other transportation vehicles based on the driving intention.

3. The method of claim 1, wherein the determination corresponds to satellite-based determination of the position.

4. The method of claim 1, further comprising obtaining information about external trigger variables for the determination of the driving intention via a vehicle-to-vehicle interface, wherein the determination is also based on the information about the external trigger variables.

5. The method of claim 4, wherein the information about the external trigger variables comprises at least one element from the group of vehicle-to-vehicle status messages, vehicle-to-vehicle driving intention messages and vehicle-to-vehicle messages with information on the surroundings of one or more other transportation vehicles.

6. The method of claim 1, wherein the triggering conditions are based on one or more probability functions based on the trigger variables.

7. The method of claim 1, wherein the determination is also based on a navigation function of the transportation vehicle.

8. The method of claim 1, wherein the determination is also based on information about traffic regulations, wherein the determination of the driving intention determines the driving intention so that no traffic regulations are infringed.

9. The method of claim 1, wherein the determination is based on a learning function, wherein the determination also bases the driving intention on preceding driving maneuvers of a driver of the transportation vehicle.

10. A transportation vehicle communication system for determining a driving intention for a transportation vehicle, wherein the driving intention comprises information about a predicted driving maneuver, comprising:

determining a position of the transportation vehicle;

identifying a section of road based on the position of the transportation vehicle and a digital map, wherein one or more possible driving intentions are assigned to the section of road, and wherein the one or more possible driving intentions are assigned one or more triggering conditions based on one or more trigger variables;

assigning two or more possible driving intentions to the identified section of road;

obtaining information about internal trigger variables based on on-board sensors or actuators of the transportation vehicle;

assigning one or more triggering conditions to the two or more possible driving intentions and assigning probability of intention to each of the one or more trigger conditions if met; and

determining the driving intention based on the identified section of road, the information about the internal trigger variables and the one or more triggering conditions.

11. The system of claim 10, further comprising making available a driving intention message via a vehicle-to-vehicle interface for one or more other transportation vehicles based on the driving intention.

12. The system of claim 10, wherein the determination corresponds to satellite-based determination of the position.

13. The system of claim 10, wherein the system obtains information about external trigger variables for the determination of the driving intention via a vehicle-to-vehicle interface, wherein the determination is also based on the information about the external trigger variables.

14. The system of claim 13, wherein the information about the external trigger variables comprises at least one element from the group of vehicle-to-vehicle status messages, vehicle-to-vehicle driving intention messages and vehicle-to-vehicle messages with information on the surroundings of one or more other transportation vehicles.

15. The system of claim 10, wherein the triggering conditions are based on one or more probability functions based on the trigger variables.

16. The system of claim 10, wherein the determination is also based on a navigation function of the transportation vehicle.

17. The system of claim 10, wherein the determination is also based on information about traffic regulations, wherein the determination of the driving intention determines the driving intention so that no traffic regulations are infringed.

18. The system of claim 10, wherein the determination is based on a learning function, wherein the determination also bases the driving intention on preceding driving maneuvers of a driver of the transportation vehicle.

19. A non-transitory software medium that includes instructions, which when implemented by a processor, perform a method for determining a driving intention for a transportation vehicle, wherein the driving intention comprises information about a predicted driving maneuver, the method comprising:

determining a position of the transportation vehicle;

identifying a section of road based on the position of the transportation vehicle and a digital map;

assigning two or more possible driving intentions to the identified section of road;

obtaining information about internal trigger variables based on on-board sensors or actuators of the transportation vehicle;

assigning one or more triggering conditions to the two or more possible driving intentions and assigning probability of intention to each of the one or more trigger conditions if met; and

determining the driving intention based on the identified section of road, the information about the internal trigger variables and the one or more triggering conditions.
