Adaptive Frontlighting System (AFS)

The low beam is only a compromise of all partial light distributions. That’s why the dynamic Adaptive Frontlighting System was developed to permit the best possible illumination of the road depending on speed and steering angle. Achieving this requires a VarioX projection module with a rotating cylinder between the light source and the lens. Typically, the cylinder has varying contours and can also rotate around its own longitudinal axis. A stepper motor turns the cylinder to the required position within milliseconds.

Town light, which is activated at speeds below 55 km/h, features a horizontal cut-off line to minimize glare for other people on the road. Wide light distribution also makes it easier to detect pedestrians at the side of the road.

Country road light is also activated between speeds of 55 and 100 km/h and is similar to conventional low beam light distribution. The VarioX module generates an asymmetrical light distribution pattern to minimize glare for oncoming drivers. The cut-off line is raised so that the left edge of the road is better illuminated, providing greater coverage.

Motorway light is activated at speeds above 100 km/h. The light distribution range is designed for wide curve radii at high speeds.
The high beam of the AFS works like a conventional high beam, but does not require the driver to take action to avoid exposing oncoming drivers to excessive glare.

The Adaptive Frontlighting System also has a dynamic bend lighting function. Depending on the steering angle, the headlamps also swivel by up to 15° and allow optimized illumination of the bend.

Adverse weather light creates a wider dispersion of the light to improve visibility in rain, fog or snow. This feature also reduces long-range illumination to minimize reflective glare affecting the driver’s own vehicle.
