  • the adjusting device can illuminate the lighting device. tion on the one hand to adjust the vertical axis of the motor vehicle and the other to the vehicle longitudinal axis. On the one hand, this reduces the number of lighting devices required and also improves the continuous detection of an object approaching the motor vehicle, since the optical marking can be held on the object by one and the same lighting device by means of the adjusting device instead of by switching between a plurality of lighting devices switch.

Due to this, for example, depending on the distance of an object from the motor vehicle, the object can be illuminated and marked in a corresponding color. Depending on the color with which the object located in the vehicle surroundings is illuminated, the driver can thus assess immediately how critical the distance between object and motor vehicle is. Furthermore, it is possible to adjust the color preferably continuously to the distance of the object from the motor vehicle by the combination of several lamps or the use of an LED. For example, a farther object can be marked with yellow light, with the Color of the lighting can be changed as the object approaches, for example via orange to red.

This can be done, for example, on the basis of the distance to the motor vehicle or the trajectory of the motor vehicle.
  • control device controls the illumination device in such a way that it emits light, wherein the emitted light can be adjusted with regard to its wavelength and / or its color and / or its intensity. Because of this adjustment, objects that are located at different distances from the motor vehicle, can be marked accordingly with different colors. Thus, the driver instantly sees which object has the smallest distance to the motor vehicle.
