Furthermore, it is known to provide the horizontal deflection of the light cone of the headlights as a function of the steering angle, so that the light cone of the headlights is directed in a curve in the direction of the road.

  • the headlight range of the normal vehicle headlights is reduced upon detection of a fog condition.
  • the detection means is designed as a switch which serves for switching on the fog lights or the rear fog lamp of the motor vehicle, so that the headlamp range of the headlamp is reduced by switching on the fog lamp or the rear fog lamp. This can be improved in a very simple way the view for the driver.
  • the detection means can also be designed as an optical sensor, so that the light range is automatically reduced when the optical sensor detects a fog condition.
  • the headlamp range of the headlamp is reduced by the inclination of the headlamp. It is equally advantageous if the headlight has a reflector and the headlight range is reduced by a movement or adjustment of the reflector.
  • the method is further improved by the fact that the fog state is characterized by a variable, for example the fog density, the recognition means recognizes this size and the reduction of the illumination range takes place as a function of this size.

  • This may be a servo motor or a piezo or polymer actuator which is capable of tilting the reflector 18. This is the case, for example, when the motor vehicle is heavily loaded in the rear area, so that the direction of illumination of the headlamps is directed too far upwards in normal low beam and therefore an excessive headlamp range is reached, the opposite - A -

  • the controller 14 which controls the adjusting means 20, thereupon, according to the invention, lowers the light beam for the low beam of the headlamp 10, by correspondingly adjusting the reflector 18 of the headlamp 10, so that the headlight range of the headlamp 10 is reduced and glare of the driver is prevented.
  • the entire headlight 10 can be inclined downwards in the direction of the roadway and thus lowered, so that this also takes place a headlight range reduction.
  • appropriate panels or additional reflectors can be used for this purpose.
  • Another possibility is to provide the recognition means 12 as a sensor, in particular an optical sensor. Such sensors are already known and serve to control windshield wiper devices. If such a sensor now recognizes a fog condition as recognition means 12, then the rear fog lamp and / or the fog lamps 24 can be switched on and a signal can be transmitted to the controller 14. The controller 14 is then able to reduce the beam range of the headlamp 10.

In this case, then in a reset step 34, the headlamp range of the headlamp 10 is raised back to its normal position.
  • the headlights 10 correspond to the normal headlights of the motor vehicle, which are also provided for the low beam and the high beam, so that no additional headlights are needed.
