Abstract

A driver assistance system for controlling a high beam, including an environment detecting device. At least one radar or lidar sensor system as well as a camera sensor system are provided for detecting the environment in front of the vehicle. A control signal for a high beam controller or warning device is generated when the high beam is active and at least one sensor system for detecting the environment simultaneously detects a potentially dazzled object.

First claim

The invention claimed is:

1. A method for a driver assistance system for controlling a high beam, the driver assistance system comprising i) a radar sensor system or a lidar sensor system, and ii) a camera sensor system for detecting the environment in front of a vehicle, the method comprising:
generating a control signal for a high beam controller or a warning device when the high beam is active and a potentially dazzled object is:
1) simultaneously detected by i) the radar sensor system or the lidar sensor system, and ii) the camera sensor system, or
2) detected by the radar or lidar sensor system, and not detected by the camera sensor system.

2. The method according to claim 1 , further comprising:
generating a control signal when the high beam is active and a potentially dazzled object is simultaneously detected by the radar or lidar sensor system and the camera sensor system.

3. The method according to claim 2 , wherein
if additional, specified environment information is available, a control signal is also generated when a potentially dazzled object is only detected by the radar or lidar sensor system.

4. The method according to claim 1 , further comprising:
generating a control signal when the high beam is active and a potentially dazzled object is detected by the radar or lidar sensor system, but not by the camera sensor system.

5. The method according to claim 4 , further comprising:
generating a control signal when the high beam is active and a potentially dazzled object is detected by the radar or lidar sensor system, but not by the camera sensor system and
detecting an increased development at the edge of the road.

6. The method according to claim 4 , wherein
a control signal is generated when the high beam is active and a potentially dazzled object is detected by the radar or lidar sensor system, but not by the camera sensor system and
a traffic circle lying ahead of the vehicle is detected.

7. The method according to claim 1 ,
wherein if additional, specified environment information is available, a control signal is also generated when a potentially dazzled object is only detected by the radar or lidar sensor system.

8. The method according to claim 1 , wherein
at least one sensor system, for detecting the environment detects a development at the edge of the road.

9. The method according to claim 8 , further comprising:
generating a control signal when the high beam is active and a potentially dazzled object is detected by the radar or lidar sensor system, but not by the camera sensor system and an increased development at the edge of the road is detected.

10. The method according to claim 1 , wherein
means for detecting a traffic circle lying ahead are provided.

11. The method according to claim 10 , wherein
a control signal is generated when the high beam is active and a potentially dazzled object is detected by the radar or lidar sensor system, but not by the camera sensory system and a traffic circle lying ahead of the vehicle is detected.

12. The method according to claim 1 , which comprises a radar or lidar sensor system having a controllable range, wherein the radar or lidar sensor system is also used for other driver assistance functions, wherein
a high sensor range is selected, if no relevant objects are located in a range which is relevant for another driver assistance function.

13. The method according to claim 1 , wherein in response to the signal, a warning is given to the driver using audible, visual or haptic means or the high beam is switched off or the range of the high beam is reduced or the light cone of the high beam is formed in such a manner that the potentially dazzled moving object is omitted in the light cone.

14. A driver assistance system for controlling a high beam of a vehicle comprising:
i) a radar sensor or a lidar sensor system, and ii) a camera sensor system for detecting the environment in front of a vehicle, and
a control unit configured to generate a control signal for a high beam controller or a warning device when the high beam is active and a potentially dazzled object is:
1) simultaneously detected by i) the radar sensor system or the lidar sensor system, and ii) the camera sensor system, or
2) detected by the radar or lidar sensor system, and not detected by the camera sensor system.
