Abstract

A method and a device for illuminating an edge region of a roadway by headlights of a vehicle are disclosed. The vehicle includes a camera. Activating takes place of at least one additional illuminating device or a masking of an headlight that is present on the vehicle. An additional illuminated region is generated which extends in the vertical and the lateral direction with respect to the vehicle. Activating the at least one additional illuminating device or headlight masking at least one headlight present in the vehicle takes place by a navigation system of the vehicle or in response to a decrease in the speed of the vehicle and/or by an object/traffic sign detection using the camera.

Claims

1. A method for illuminating an edge region of a roadway by at least one headlight of a vehicle, which passes along the roadway and which includes a camera, the method comprising:

activating a masking of a headlight that is already present; and

generating an additional illuminated region in a vertical and a lateral extension with reference to the vehicle,

wherein the activation of the masking of a headlight that is already present takes place via a navigation system of the vehicle, or in response to the decrease in the speed of the vehicle and/or by an object/traffic sign recognition by the camera.

2. The method as recited in claim 1, wherein the activation of the masking of a headlight that is already present takes place in response to a deceleration of the vehicle and/or in response to falling below a certain, individually specifiable speed threshold.

3. The method as recited in claim 2, wherein the activation of the masking of at least one headlight that is already present takes place by a day/night detection or in response to bad weather.

4. The method as recited in claim 1, wherein the activation of the masking of at least one headlight already present takes place using the camera, particularly embodied as the video camera, by an object detection and a traffic sign detection.

5. A method for illuminating an edge region of a roadway by at least one headlight of a vehicle, which passes along the roadway and which includes a camera, the method comprising:

activating at least one additional illuminating device or a masking of a headlight that is already present; and

generating an additional illuminated region in a vertical and a lateral extension with reference to the vehicle,

wherein the activation of the at least one additional illuminating device or of the masking of a headlight that is already present takes place via a navigation system of the vehicle, or in response to the decrease in the speed of the vehicle and/or by an object/traffic sign recognition by the camera, and

wherein the activation of the at least one additional illuminating device or the at least one headlight masking of a headlight that is already present, takes place by the navigation system of the vehicle as soon as a branching-off, a fork in the road, or a crossing is reached.

6. A method for illuminating an edge region of a roadway by at least one headlight of a vehicle, which passes along the roadway and which includes a camera, the method comprising:

activating at least one additional illuminating device or a masking of a headlight that is already present; and

generating an additional illuminated region in a vertical and a lateral extension with reference to the vehicle,

wherein the activation of the at least one additional illuminating device or of the masking of a headlight that is already present takes place via a navigation system of the vehicle, or in response to the decrease in the speed of the vehicle and/or by an object/traffic sign recognition by the camera, and

wherein the activation of the at least one additional illuminating device or the headlight masking of a headlight that is already present, takes place by activating a night vision system function, by an individual signal of the driver or by a corresponding signal of a day/night-detecting light sensor.

7. A device configured to implement a method for illuminating an edge region of a roadway by at least one headlight of a vehicle, which passes along the roadway and which includes a camera, the method comprising:

activating at least one additional illuminating device provided in addition to headlights of a vehicle, the at least one additional illuminating device being developed as a separate headlight which is located in the fender region of the vehicle or in the region of one or both front headlights of the vehicle; and

generating an additional illuminated region in a vertical and a lateral extension with reference to the vehicle,

wherein the activation of the at least one additional illuminating device takes place via a navigation system of the vehicle, or in response to the decrease in the speed of the vehicle and/or by an object/traffic sign recognition by the camera.

8. The device as recited in claim 7, wherein the at least one additional illuminating device is integrated into a fog light or a daytime running light function.

9. The device as recited in claim 7, wherein the at least one additional illuminating device is designed to be selectively controllable, particularly to be dimmable, and radiates light in the IR and/or the VIS range and/or is integrated into a headlight range regulation.

10. The device as recited in claim 7, wherein in the case of the development of the headlight as an LED headlight module, individual LED'"'"'s face the edge of the roadway, generate an additional illuminated region and are configured to be individually switched on and off.
