One of the first light-based assistance systems was the dynamic bend lighting function, which was introduced in 2003. In this system, the light modules rotate according to the steering angle, nearly doubling the range of visibility in a curve.
One advanced development based on dynamic bend lighting is the Adaptive Frontlight System (AFS). This system uses both the steering angle and the vehicle speed as parameters for illuminating the road. Based on this internal information, a cylinder in the VarioX module is used to create various types of light distribution, including town light, country light, adverse weather and motorway light.
The development of the adaptive cut-off line (aCOL) goes one step further. This feature also utilizes data gathered from the vehicle’s surroundings to generate the light distribution. A camera detects oncoming traffic and cars ahead, and a stepper motor turns the cylinder of the VarioX module to the required position within milliseconds. This means that the light cone always ends directly in front of oncoming traffic, or just behind the car ahead of you.
The glare-free high beam function means that drivers can drive with the high beam on at all times. If the camera detects other traffic on the road, the distribution of light from the high beams is adjusted to mask the specific area.
Now used to illuminate broader areas than ever before, LEDs will also perform the opposite function in the future. Targeted spotlighting functions will allow specific illumination of certain types of objects, such as children playing at the edge of the road. This draws the driver’s attention to these potential risks ahead of time, enabling faster responses.
