Abstract

A method for operating a driver information system in an ego vehicle is provided wherein an additional road user is detected in a road area lying in front of the ego vehicle. A target trajectory for the ego vehicle is generated by a driver assistance system for at least partially automatic transverse control of the ego vehicle depending on the additional road user, and a driver information display is generated and output. The driver information display comprises a graphic road user object that represents the additional road user. The driver information display furthermore comprises a trajectory object which represents the target trajectory of the ego vehicle.

First claim

What is claimed is:

1. A method for operating a driver information system in an ego vehicle, comprising:
detecting an additional road user in a road area lying in front of the ego vehicle;
determining at least one depiction-relevant feature of the additional road user, comprising a state of a lighting system of the additional road user;
generating a target trajectory for the ego vehicle by a driver assistance system for at least partially automatic transverse control of the ego vehicle depending on the additional road user; and
generating and outputting a driver information display; wherein
the driver information display is generated to comprise a graphic road user object that represents the additional road user, which graphic road user object reflects the at least one depiction-relevant feature;
the driver information display is generated to comprise a trajectory object which represents the target trajectory of the ego vehicle; and
the driver information display is generated to not include an output of a video image that is detected by a camera of the ego vehicle.

2. The method of claim 1 , wherein
the driver information display comprises a graphic lane object which represents a course of a road lying in front of the ego vehicle; wherein
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 1 , wherein
the driver information display comprises an ego object which represents the ego vehicle; and
the trajectory object extends from the ego object to the road user object.

4. The method of claim 1 , comprising:
detecting a planned lane change of the ego vehicle; and
determining the target trajectory of the ego vehicle for the lane change.

5. The method of claim 1 , comprising:
establishing a datalink between the ego vehicle and the additional road user; and
acquiring the depiction-relevant feature by means of the datalink.

6. The method of claim 1 , comprising:
detecting an operating state of the driver assistance system of the ego vehicle; and
determining an automation level with reference to the detected operating state of the driver assistance 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.

7. The method of claim 1 , comprising:
detecting a course of a road lying in front of the ego vehicle in the driving direction, including a radius of curvature of the curve;
detecting movement data of the ego vehicle;
determining a criticality by using the detected movement data and the detected radius of curvature; and
generating a highlight feature of the graphic lane object depending on the determined criticality.

8. A driver information system in an ego vehicle, with
a detector that is configured to detect an additional road user in a road area lying in front of the ego vehicle;
circuitry for detecting at least one depiction-relevant feature of the additional road user, comprising a state of a lighting system of the additional road user;
a driver assistance system for an at least partially automatic transverse control of the ego vehicle that is configured to generate a target trajectory of the ego vehicle depending on the additional road user; and
a control circuit that is configured to generate and output a driver information display; wherein
the driver information display is generated to comprises a graphic road user object that represents the additional road user, which graphic road user object reflects the at least one depiction-relevant feature;
the driver information display is generated to comprise a trajectory object which represents the target trajectory of the ego vehicle; and
the driver information display is generated to not include an output of a video image that is detected by a camera of the ego vehicle.

9. The driver information system of claim 8 , comprising a display with a field-of-vision display for outputting the driver information display.

10. The method of claim 2 , wherein
the driver information display comprises an ego object which represents the ego vehicle; and
the trajectory object extends from the ego object to the road user object.

11. The method of claim 2 , further comprising:
detecting a planned lane change of the ego vehicle; and
determining the target trajectory of the ego vehicle for the lane change.

12. The method of claim 3 , further comprising:
detecting a planned lane change of the ego vehicle; and
determining the target trajectory of the ego vehicle for the lane change.

13. The method of claim 2 , comprising:
detecting an operating state of the driver assistance system of the ego vehicle; and
determining an automation level with reference to the detected operating state of the driver assistance 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.
