Abstract

The present disclosure relate to a motor vehicle comprising a sensor device for detecting the position and the distance from an object located in front of the motor vehicle and a device for projecting a light marker onto the ground in the region of the object, wherein the device is configured, on the basis of the detected position and distance data, to project either a round or polygonal light marker on a region around the object, wherein this is dimensioned is such a way that its border is indicates a minimum distance to be maintained around the object when driving past, and/or the device is configured to generate a linear light marker and project it on the ground into the region in front of the motor vehicle running by the object in such a way that the distance of the light marker corresponds to the minimum distance to be maintained from the object when driving past and indicates when the motor vehicle can reenter the lane after passing the object while maintaining a safe distance.

First claim

The invention claimed is:

1. A motor vehicle comprising:
a sensor device configured to detect a position of and a distance from an object located in front of the motor vehicle; and
a projection device configured to project, based on the position and the distance, a light marker onto a ground near the object, the light marker being round, polygonal, and/or linear,
wherein, if the light marker is round or polygonal, the light marker is projected to indicate a minimum distance to be maintained around the object when driving past, and
wherein, if the light marker is linear, the light marker is projected to correspond to a minimum distance to be maintained from the object when driving past, the light marker indicating where the motor vehicle can safely reenter a driving lane after passing the object.

2. The motor vehicle according to claim 1 , wherein the light marker is round or polygonal, the light marker being a ring, a frame, or a completely illuminated area.

3. The motor vehicle according to claim 2 , wherein the light marker is round or polygonal, the light marker being a ring or a frame, and the light marker indicates an off-limits area.

4. The motor vehicle according to claim 1 , wherein the light marker is linear, the light marker being a line that represents a lateral road boundary.

5. The motor vehicle according to claim 1 , wherein the light marker is linear, the light marker being a line that represents a path of travel.

6. The motor vehicle according to claim 1 , wherein the projection device is further configured to project at least one additional piece of information, the at least one additional piece of information being an illuminated display on the ground.

7. The motor vehicle according to claim 6 , wherein the illuminated display is configured to project warning information, the warning information indicating that a prescribed minimum distance cannot be observed when passing the object.

8. The motor vehicle according to claim 7 , wherein the projection device is further configured to project at least partially the at least one additional piece of information in a signal color.

9. A method for guiding a motor vehicle, the method comprising:
detecting, with a sensor device, a position relative to an object;
detecting, with the sensor device, a distance relative to the object; and
projecting a light marker onto a ground near the object, the light marker being round, polygonal, and/or linear,
wherein, if the light marker is round or polygonal, the light marker is projected to indicate a minimum distance to be maintained around the object when driving past, and
wherein, if the light marker is linear, the light marker is projected to correspond to a minimum distance to be maintained from the object when driving past, the light marker indicating where the motor vehicle can safely reenter a driving lane after passing the object.

10. The method according to claim 9 , wherein the light marker is round or polygonal, the light marker being a ring, a frame, or a completely illuminated area.

11. The method according to claim 9 , wherein the light marker is round or polygonal, the light marker being a ring or a frame, and the light marker being an off-limits area.

12. The method according to claim 9 , wherein the light marker is linear, the light marker representing a lateral path of travel.

13. The method according to claim 9 , wherein a projection device of the motor vehicle is configured to project at least one additional piece of information, the at least one additional piece of information being an illuminated display on the ground.

14. The method according to claim 13 , wherein the illuminated display is configured to project warning information, the warning information indicating that a prescribed minimum distance cannot be observed when passing the object.

15. The method according to claim 14 , wherein the projection device is further configured to project at least partially the at least one additional piece of information in a signal color.
