Previously, headlights could be switched only on or off and from low beam to high beam. Today, thanks to functional algorithms, they respond sensitively to driving situations and initiate changes in lighting. In doing so, they help the driver when visibility is poor, for example, or purposefully direct the driver’s attention towards objects that are selectively lit according to the situation. In addition, they help and protect other road users.
Functional algorithms utilize a lot of internal and external information that is already available in the vehicle, analyzing it and adjusting the light accordingly. Simple applications include elements that go out or dim when the turn signal is activated, automatically switch to low beam when there is oncoming traffic or activate cornering lights based on map data. More complex applications include the detection of pedestrians, cyclists and animals, the illumination of traffic signs and the glare-free high beam headlight useful for vehicles traveling in front and in oncoming traffic.
Analyzing the information from sensors (e.g. camera, radar) and map data can help improve visibility for drivers and other road users.
Standardized driving situations are recognized and initiate an intelligent response that takes the pressure off the driver and increases safety.
The information that is available in and collected by the vehicle is connected and analyzed to broaden the driver’s knowledge.
Currently, many standard situations and the appropriate responses are defined. The more the intelligence of vehicles develops, the more standard situations will be added. This also plays an important role in moving towards automated driving
Functional algorithms utilize the internal and external information that is available in the vehicle, such as that from sensors, the speedometer, the angle of the steering wheel, the windshield wipers, etc. or from map data.
Defined light scenarios resulting in automated responses make journeys safer and more comfortable for all concerned.
The number and type of light scenarios are constantly evolving and are a key area of innovation in the automotive sector.
In self-driving vehicles, intelligent light functions can help optimize the driver handover/takeover process and thereby increase the level of safety. Light also plays an important role as a means of communicating with other road users.
