both, the ego-object and the trailer object are represented from behind in a perspective view and the driver information display also comprises a lane object which represents a road section lying in front of the ego-vehicle in the direction of travel; wherein

the trailer object is formed according to the recorded operating state of the trailer device.

2. The method of claim 1 , wherein

a road path lying in front of the ego-vehicle is recorded using sensors of the ego-vehicle; and

the lane object is formed such that it corresponds to a perspective depiction of the road path and comprises a radius of curvature such that the actual radius of curvature of a curve of the road path is output.

3. The method of claim 2 , wherein a position of the ego-vehicle is determined; and the road path is recorded using map data and using the specific position.

4. The method of claim 3 , further comprising

evaluating, whether a lane change to an adjacent lane may be carried out safely; wherein

the driver information display comprises an adjacent lane object; and wherein

the adjacent lane object has a graphic depiction feature which is formed according to whether the lane change may be carried out safely.

5. The method of claim 3 , further comprising

recording environmental data in an environment of the ego-vehicle; and

determining a level of automation of a driver assist system of the ego-vehicle; wherein

the driver information display comprises a graphic depiction of the environment which is formed according to the specific level of automation.

6. The method of claim 3 , further comprising

determining a boundary marking on the road section lying in front of the ego-vehicle in the direction of travel using recorded environmental data; and

determining a boundary marking class for the specific boundary marking; wherein

the driver information display comprises a graphic boundary object which is formed according to the specific boundary marking class.

7. The method of claim 2 , further comprising

evaluating, whether a lane change to an adjacent lane may be carried out safely; wherein

the driver information display comprises an adjacent lane object; and wherein

the adjacent lane object has a graphic depiction feature which is formed according to whether the lane change may be carried out safely.

8. The method of claim 2 , further comprising

recording environmental data in an environment of the ego-vehicle; and

determining a level of automation of a driver assist system of the ego-vehicle; wherein

the driver information display comprises a graphic depiction of the environment which is formed according to the specific level of automation.

9. The method of claim 2 , further comprising

determining a boundary marking on the road section lying in front of the ego-vehicle in the direction of travel using recorded environmental data; and

determining a boundary marking class for the specific boundary marking; wherein

the driver information display comprises a graphic boundary object which is formed according to the specific boundary marking class.

10. The method of claim 1 , further comprising

evaluating, whether a lane change to an adjacent lane may be carried out safely; wherein

the driver information display comprises an adjacent lane object; and wherein

the adjacent lane object has a graphic depiction feature which is formed according to whether the lane change may be carried out safely.

11. The method of claim 10 , further comprising

recording environmental data in an environment of the ego-vehicle; and

determining a level of automation of a driver assist system of the ego-vehicle; wherein

the driver information display comprises a graphic depiction of the environment which is formed according to the specific level of automation.

12. The method of claim 10 , further comprising

determining a boundary marking on the road section lying in front of the ego-vehicle in the direction of travel using the recorded environmental data; and

determining a boundary marking class for the specific boundary marking; wherein

the driver information display comprises a graphic boundary object which is formed according to the specific boundary marking class.

13. The method of claim 1 , further comprising

recording environmental data in an environment of the ego-vehicle; and

determining a level of automation of a driver assist system of the ego-vehicle; wherein

the driver information display comprises a graphic depiction of the environment which is formed according to the specific level of automation.

14. The method of claim 13 , further comprising

determining a boundary marking on the road section lying in front of the ego-vehicle in the direction of travel using the recorded environmental data; and

determining a boundary marking class for the specific boundary marking; wherein

the driver information display comprises a graphic boundary object which is formed according to the specific boundary marking class.

15. The method of claim 1 , further comprising

determining a boundary marking on the road section lying in front of the ego-vehicle in the direction of travel using recorded environmental data; and

determining a boundary marking class for the specific boundary marking; wherein

the driver information display comprises a graphic boundary object which is formed according to the specific boundary marking class.

16. The method of claim 1 , further comprising

determining a radius of curvature of a curve lying in front of the ego-vehicle; and

recording movement data of the ego-vehicle; wherein

a criticality is determined on the basis of the recorded movement data and the detected radius of curvature; and

the graphic lane object is formed with a highlighting feature which is formed according to the determined criticality.

17. The method of claim 1 , wherein the graphic lane object also has a depiction parameter which is formed according to the road surface properties or weather data.

18. The method of claim 1 , wherein the generated driver information display does not include an output of a video image that is recorded by a camera of the ego-vehicle.

19. A driver information system in an ego-vehicle comprising:

a detector which is configured to record an operating state of a trailer device of the ego-vehicle; and

a control circuit which is configured to, during forward driving of the ego-vehicle, generate a driver information display and output same; wherein

the driver information display comprises a graphic ego-object which represents the ego-vehicle and a trailer object which represents a device, attached to the vehicle; wherein

the control circuit is configured to represent both, the ego-object and the trailer object from behind in a perspective view and to generate the driver information display such that it also comprises a lane object which represents a road section lying in front of the ego-vehicle in the direction of travel; wherein

the control circuit is configured to form the driver information display such that the trailer object is formed according to the recorded operating state of the trailer device.

20. The driver information system of claim 19 , wherein the display unit comprises a field of view display for the output of the driver information display.
