Automatic headlight beam throw adjustment

As standard, vehicles with LED headlights have automatic headlight beam throw adjustment to compensate different load statuses of the vehicle.

The automatic headlight beam throw adjustment for the LED headlight includes the following functions:

• Dynamic headlight beam throw adjustment

  The dynamic headlight beam throw adjustment was developed for compensating pitching movements that occur as a result of braking and acceleration.

• Adaptive headlight beam throw adjustment

  Adaptive headlight beam throw adjustment uses driving condition signals to identify driving over rises or dips. The headlights are accordingly vertically swivelled via a stepper motor. The automatic headlight beam throw adjustment thus ensures that oncoming traffic is not dazzled.

  The headlight is increased while driving through a dip. The driving area visibility is enhanced without blinding oncoming traffic. Roadway obstacles are recognized earlier than with previous headlight systems. This makes it possible to react to obstacles early and initiate evasive maneuvers as required.

  The headlight beam throw is lowered when driving over a rise. The driver of an approaching vehicle is subjected to less glare than with the headlight systems used up to now.

The automatic headlight beam throw adjustment is supported by 2 ride height sensors. one ride height sensor each located on the front axle and the rear axle of the vehicle. The ride height sensors are directly evaluated by the Body Domain Controller (BDC). The Body Domain Controller (BDC) activates the stepper motor for the headlight beam throw adjustment.
