Method for selecting an evaluation object for a function in a motor vehicle

1. A method for selecting, by a driver of a motor vehicle, a road user using at least one display device which is configured to display the road user, the method comprising: after a first operating action is carried out, activating a search function such that at least a subset of road users is individually marked on the at least one display device in a sequence that contains the road users; and when a second operating action is carried out, or after a predetermined first time period, selecting, from the subset of road users, an individually marked road user as an evaluation object of a function of a driver assistance system of the motor vehicle.

2. The method according to claim 1 , further comprising:

automatically marking a next road user in response to the second operating action not being performed within a second time period.

3. The method according to claim 2 , further comprising:

adjusting the predetermined first time period or the second time period based at least on a driving situation parameter describing a current driving situation.

4. The method according to claim 3 , further comprising:

selecting a value for the predetermined first time period or the second time period based on a current speed of the motor vehicle or a current driving situation class.

5. The method according to claim 1 , further comprising:

determining the road users based on at least one requirement criterion that is used for evaluating road user information related to a respective road user; or

varying a type of marking based on the at least one requirement criterion or an other requirement criterion.

6. The method according to claim 5 , wherein the at least one requirement criterion is adjustable by the user.

7. The method according to claim 5 , wherein:

the at least one requirement criterion describes suitability as the evaluation object, the suitability relates to metrological detectability of the respective road user or a driving style of the respective road user, or

the at least one requirement criterion is based on results of a driving situation analysis.

8. The method according to claim 5 , further comprising:

determining the road user information, at least partially, from communication data of automobile-to-automobile communication.

9. The method according to claim 8 , further comprising:

verifying whether a next route segment, having a minimum length, is shared by the respective road user and the motor vehicle or whether a common destination exists for the respective road user and the motor vehicle.

10. The method according to claim 5 , further comprising: varying a color or a geometric shape of a symbol which marks the individually marked road user.

11. The method according to claim 10 , further comprising:

selecting a sequence of markings of the road users based on the at least one requirement criterion.

12. The method according to claim 11 , further comprising:

determining a suitability value which describes a degree of suitability as the evaluation object, wherein the suitability relates to metrological detectability of the road user or a driving style of the respective road user; and

continuously depicting the suitability value by a color or a geometric shape of the symbol; or

determining the sequence of the markings based on the suitability value.

13. The method according to claim 5 , further comprising:

adjusting the at least one requirement criterion based on a driving situation parameter describing a driving situation such that a number of the road users is reduced when the driving situation involves increased driver attention.

14. The method according to claim 1 , further comprising:

selecting one of a plurality of possible functions based on a third operating action preceding the first operating action.

15. The method according to claim 1 , further comprising:

after selecting the evaluation object, marking the selected evaluation object in a different manner on the at least one display device.

16. The method according to claim 1 , further comprising:

using a head-up display device, which uses a windshield of the motor vehicle through which the road users are seen, as the at least one display device.

17. The method according to claim 1 , further comprising:

using at least one follow function as the function, wherein the evaluation object is a follow object.

18. The method according to claim 1 , wherein a marking used to mark the at least the subset of road users comprises a crosshair.

19. A motor vehicle, comprising: at least one display device; and a control device configured to select a road user, based on a selection of a driver, using the at least one display device which is configured to display the road user, by: after a first operating action is carried out, activating a search function such that at least a subset of road users is individually marked on the at least one display device in a sequence containing the road users; and when a second operating action is carried out, or after a predetermined first time period, selecting, from the subset of road users, an individually marked road user as an evaluation object of a function of a driver assistance system of the motor vehicle.
