Abstract

The invention relates to a method for checking the functionality of a motor vehicle (10) having a headlight (12) comprising a laser (14) for generating light, whereby a converter ( 16) to output converted light emitted by the headlight (12) for generating a predeterminable light distribution (18) on a surface (20) in the ambient area of ​​the motor vehicle (10), wherein A predeterminable light distribution (18) is set via a control unit (22) of the headlight (12). The object of the invention is to check the state of the converter (16). A test pattern (26, 30) is set as a light distribution (18) by a control device (22). The test pattern (26, 30) on the surface (20) is detected by means of an optical detection device (24) of the motor vehicle (10). The detected test pattern (26, 30) is compared with a predetermined reference pattern by an analysis device (28) of the motor vehicle (10). Furthermore, the invention relates to a motor vehicle (10), which is designed to carry out such a method.

Description

technical field [0001] The invention relates to a method for checking the functionality of a motor vehicle. Furthermore, the invention relates to a motor vehicle. Background technique [0002] Motor vehicle headlights can use lasers as light sources. A converter can be activated by means of the laser for outputting converted light. Such converters may for example comprise crystal elements formed of Ce:YAG, a special form of yttrium-aluminum-garnet. These lasers are generally used to generate light with a particularly high intensity in a particularly narrow wavelength range. On the other hand, the converter outputs light in a different, in particular broad, wavelength range when activated, that is to say it converts the light generated by the laser. In particular, therefore, white light with a temperature of, for example, 5500 Kelvin can be produced, which is particularly comfortable for all road users. [0003] The light output by the converter is emitted by the headlig...
