Method for operating a driver information system in an ego-vehicle and driver information system
A method for operating a driver information system in an ego vehicle is provided, in which a current speed of the ego vehicle and a set parameter of an at least partially automated longitudinal guidance function of a driver assist system are acquired. A driver information display is generated and output, wherein the driver information display comprises a graphic lane object which represents a roadway in front of the ego vehicle. In doing so, a distance scale object and a distance indicator object are arranged in the lane object and are generated depending on the current speed of the ego vehicle. The distance scale object is generated so that positions of the lane object are assigned to distances from the ego vehicle, and the distance indicator object is arranged on the distance scale object such that the set parameter is output.

identifying an additional road user based on the captured environment data; wherein
the driver information display comprises a graphic road user object which represents the additional road user; wherein
a depiction-relevant feature of the additional road user is determined; and
the road user object assigned to the additional road user is generated depending on the depiction-relevant feature.
7. The method of claim 1 , further comprising:
capturing environment data in an environment of the ego-vehicle;
determining a demarcation marker on the roadway using the captured environment data; and
determining a demarcation marker class for the determined demarcation marker, wherein
the driver information display includes a graphic demarcation object that is generated depending on the determined demarcation marker class.
8. The method of claim 1 , further comprising:
recording an operating state of the driver assist system of the ego vehicle;
determining an automation level with reference to the recorded operating state of the driver assist system; wherein
the driver information display includes a depiction of the environment of the ego vehicle that is generated depending on the determined automation level.
9. A driver information system in an ego vehicle, with
a detector that is configured to record a current speed of the ego vehicle and a set parameter of an at least partially automated longitudinal guidance function of a driver assist system;
a control circuit that is configured to produce and output a driver information display; wherein
the driver information display comprises a graphic lane object which represents a roadway in front of the ego vehicle; wherein
a distance scale object and a distance indicator object are arranged with the lane object and are generated depending on the current speed of the ego vehicle; wherein
the distance scale object is formed so that positions of the lane object are assigned to distances from the ego vehicle; and wherein
the distance indicator object is arranged with the distance scale object such that the set parameter is output.
10. The driver information system of claim 9 , further comprising a display that includes a field-of-vision display for outputting the driver information display.
11. The method of claim 2 , wherein the parameter of the longitudinal guidance function is adjustable by a certain number of levels.
12. The method of claim 2 , further comprising acquiring a user input and changing the set parameter using the user input.
13. The method of claim 3 , further comprising acquiring a user input and changing the set parameter using the user input.
14. The method of claim 2 , wherein the graphic lane object is generated so that it corresponds to a perspective depiction of a course of a roadway and includes a radius of curvature such that an actual radius of curvature is output.
15. The method of claim 3 , wherein the graphic lane object is generated so that it corresponds to a perspective depiction of a course of a roadway and includes a radius of curvature such that an actual radius of curvature is output.
16. The method of claim 4 , wherein the graphic lane object is generated so that it corresponds to a perspective depiction of a course of a roadway and includes a radius of curvature such that an actual radius of curvature is output.
17. The method of claim 2 , further comprising:
capturing environment data in an environment of the ego-vehicle; and
identifying an additional road user based on the captured environment data; wherein
the driver information display comprises a graphic road user object which represents the additional road user; wherein
a depiction-relevant feature of the additional road user is determined; and
the road user object assigned to the additional road user is generated depending on the depiction-relevant feature.
18. The method of claim 3 , further comprising:
capturing environment data in an environment of the ego-vehicle; and
identifying an additional road user based on the captured environment data; wherein
the driver information display comprises a graphic road user object which represents the additional road user; wherein
a depiction-relevant feature of the additional road user is determined; and
the road user object assigned to the additional road user is generated depending on the depiction-relevant feature.
19. The method of claim 4 , further comprising:
capturing environment data in an environment of the ego-vehicle; and
identifying an additional road user based on the captured environment data; wherein
the driver information display comprises a graphic road user object which represents the additional road user; wherein
a depiction-relevant feature of the additional road user is determined; and
the road user object assigned to the additional road user is generated depending on the depiction-relevant feature.
20. The method of claim 5 , further comprising:
capturing environment data in an environment of the ego-vehicle; and
identifying an additional road user based on the captured environment data; wherein
