I recently had the opportunity to drive a car equipped with Pixel light. These headlamps function like a data projector to an extent, because they can project images onto the road – hence their name. Controlled by camera, the Pixel light clearly illuminated road signs, pedestrians (mannequins) and turn arrows for me. While it’s a nice feature, it currently remains in the realm of science fiction, because Pixel light still lacks one, indispensable characteristic: range.
Light control by means of GPS signals is closer to use in series production vehicles. Thanks to a navigation system, the headlamp controller knows how the road in front of the car is going to turn. In other words, the beams can illuminate a curve before the driver turns the wheel. Furthermore, the headlamps no longer light up the sky at the top of a hill, or end abruptly a few feet in front of the car in dips. An automatic height correction function draws on data from the electronic map to correct this. Much more precise than systems with brightness sensors, this technology also detects approaching tunnels and switches from daytime running lights to low beams.
Assistants in general are a big trend at present. Automatic switching between high and low beams may soon emerge in the more compact vehicle classes. And we will be seeing warning signals indicating high-force braking in the form of blinking or brightened brake lights (brake force display) on an increasing number of vehicle rear ends.
