Problems solved by technology

[0003] The known low beam control has the disadvantage that, for example, the potential of the low beam for communication with the environment is not utilized or the driver is further supported with regard to visual and perceptual tasks by targeted adaptation of the light distribution.

Embodiment Construction

[0029] The examples described in detail below represent preferred embodiments of the invention. It should be noted here that the individual features can be realized not only in the combinations described, but also alone or in other technically meaningful combinations.

[0030] The invention is based on the idea that the dipped beam should be high-resolution and can be realized, for example, by pixel headlights / headlights. In this way, for example, a see-through illustration adapted to the surroundings can be achieved. Furthermore, an interaction with the environment can be carried out. Furthermore, the road topology and the distance to other vehicles can be taken into account in order to achieve a situation-dependent control of, in particular, the vehicle's lighting. The core idea here is to determine a specific viewing angle by taking into account the position of the observer and the current specific projection plane or projection surface in the environment of the vehicle f...

Abstract

The light pattern for informing or assisting the observer or the driver should be generated in an improved manner. To this end, the invention relates to a lighting device and a method for projecting a predefinable light pattern into the surroundings of a vehicle by means of a lighting device of a vehicle. Here, the projection plane (PE) in the environment of the vehicle is determined, the position of the intended observer (BO) is determined or provided, and the determined projection plane (PE) and the determined intended observer (BO) Position, pixel-by-pixel control of the lighting unit (SW) of the lighting device to generate a predeterminable light pattern.

Description

technical field [0001] The invention relates to a method for projecting a predeterminable light pattern into the surroundings of a vehicle by means of a lighting system of the vehicle. The invention also relates to a lighting device for a vehicle having a lighting unit and a control device for controlling the lighting unit. Furthermore, the invention relates to a motor vehicle having such a lighting device. Background technique [0002] Vehicles, in particular motor vehicles, are known hitherto having dipped beams which generally have a nearly static light distribution. Furthermore, low beams are generally formed from a single light source, but pixel headlights are also known. The low beam adjustment depends on information from the driver or from inside the vehicle. Little interaction with the environment occurs. [0003] A disadvantage of the known dipped beam control is that, for example, the potential of the dipped beam to communicate with the environment is not utili...
