Abstract

The disclosure relates to a method for operating a lane change assistance system, in which a detection apparatus, which is provided on a front corner of the motor vehicle, monitors an adjacent lane in front and to the side, and in which the detection apparatus detects an object on the adjacent lane and, when the detected object is evaluated by way of an electronic computing apparatus, at least one characterizing parameter of the object is determined, wherein at least one function unit detects an intention of a user of the motor vehicle to change lane and a differential speed between the motor vehicle and the object is determined as a characterizing parameter and the electronic computing apparatus generates at least one control signal for at least one further function unit on the basis of the intention to change lane and the differential speed.

First claim

What is claimed is:

1. A method for operating a lane change assistance system of a motor vehicle, comprising:
monitoring, by a detector of the lane change assistance system, which is provided in a front corner of the motor vehicle, an adjacent lane located in front and to the side of a lane on which the motor vehicle is located and detecting an object on the adjacent lane;
determining, using a processor of the lane change assistance system, at least one characterizing parameter of the object when evaluating the detected object;
detecting, using a function unit of the lane change assistance system, an intention of a user of the motor vehicle to change lane and determining a differential speed between the motor vehicle and the object as a characterizing parameter; and
generating, by the processor of the lane change assistance system, at least one control signal for at least one further function unit of the lane change assistance system on the basis of the intention to change lane and the differential speed; wherein
the object is additionally classified, and the classification is taken into account when the control signal is generated, and wherein
different driving dynamic properties of the classified object are taken into account and thus the type of object is taken into account when generating the control signal.

2. The method of claim 1 , wherein a warning signal is generated as the control signal for a warning apparatus as the further function unit.

3. The method of claim 2 , wherein a driving dynamics control signal is generated as the control signal for a driving dynamics apparatus as the further function unit.

4. The method of claim 3 , wherein a braking apparatus and/or a steering apparatus is controlled as the driving dynamics apparatus.

5. The method of claim 2 , wherein the object is additionally classified and the classification is taken into account when the control signal is generated.

6. The method of claim 2 , wherein the object can additionally be evaluated with regard to a size of the object and/or a position of the object and/or direction vector of the object and this evaluation can be taken into account when the control signal is generated.

7. The method of claim 2 , wherein the object is detected by means of at least one first detector and by means of a second detector that is designed differently to the first detector and the respectively detected object is fused by means of the electronic computing apparatus and the characterizing parameter is determined based thereon.

8. The method of claim 1 , wherein a driving dynamics control signal is generated as the control signal for a driving dynamics apparatus as the further function unit.

9. The method of claim 8 , wherein a braking apparatus and/or a steering apparatus is controlled as the driving dynamics apparatus.

10. The method of claim 9 , wherein the object is additionally classified and the classification is taken into account when the control signal is generated.

11. The method of claim 9 , wherein the object can additionally be evaluated with regard to a size of the object and/or a position of the object and/or direction vector of the object and this evaluation can be taken into account when the control signal is generated.

12. The method of claim 8 , wherein the object is additionally classified and the classification is taken into account when the control signal is generated.

13. The method of claim 8 , wherein the object can additionally be evaluated with regard to a size of the object and/or a position of the object and/or direction vector of the object and this evaluation can be taken into account when the control signal is generated.

14. The method of claim 1 , wherein the object can additionally be evaluated with regard to a size of the object and/or a position of the object and/or direction vector of the object and this evaluation can be taken into account when the control signal is generated.

15. The method of claim 1 , wherein the object is detected by means of at least one first detector and by means of a second detector that is designed differently to the first detector and the respectively detected object is fused by means of the processor and the characterizing parameter is determined based thereon.

16. The method of claim 1 , wherein the intention to change lane is detected based on a detected steering angle of the motor vehicle at a steering wheel apparatus as the function unit and/or an actuation of a turn signal lever as the function unit and/or a planned route within a navigation apparatus as the function unit.

17. The method of claim 1 , wherein a lidar sensor apparatus and/or a radar sensor apparatus and/or an ultrasound sensor apparatus and/or a camera is provided as the at least one detection apparatus.

18. A lane change assistance system for a motor vehicle, comprising: at least one detector, a processor, a function unit, and a further function unit, wherein the lane change assistance system is configured to:
monitor, by the detector, which is provided in a front corner of the motor vehicle, an adjacent lane located in front and to the side of a lane on which the motor vehicle is located and detect an object on the adjacent lane;
determine, using the processor, at least one characterizing parameter of the object when evaluating the detected object;
detect, using the function unit, an intention of a user of the motor vehicle to change lane and determine a differential speed between the motor vehicle and the object as a characterizing parameter; and to
generate, by the processor, at least one control signal for the further function unit on the basis of the intention to change lane and the differential speed; wherein
the object is additionally classified, and the classification is taken into account when the control signal is generated; and wherein
different driving dynamic properties of the classified object are taken into account and thus the type of object is taken into account when generating the control signal.
