Embodiment Construction

[0030] The examples explained hereinafter relate to preferred embodiments of the invention. In this example, however, the described components of the embodiment are corresponding individual features of the invention which are considered to be independent of each other, which correspondingly also improve the invention independently of each other and which can then also be individually or in combination with Other combinations different from the ones shown are considered to be part of the present invention. Furthermore, the embodiments described can also be supplemented by other features of the invention already described.

[0031] figure 1 and figure 2 A motor vehicle 10 with two headlights 12 is shown in a schematic plan view. In this case, the headlight 12 includes a laser 14 for generating light, whereby a converter 16 can be activated to output converted light. The light output by the converter 16 is emitted from the headlight 12 to generate a predeterminable light dis...

Abstract

The invention relates to a method for checking the functionality of a motor vehicle (10) with a headlight (12) which comprises a laser (14) for generating light, said light being used to excite a converter (16) in order to emit converted light, wherein the converted light is emitted by the headlight (12) in order to generate a specifiable light distribution (18) on a surface (20) in a region surrounding the motor vehicle (10), and the specifiable light distribution (18) is set by a controller (22) of the headlight (12). The aim of the invention is to check the state of the converter (16). A test pattern (26, 30) is set as the light distribution (18) by the controller (22); the test pattern (26, 30) is detected on the surface (20) by means of an optical detection device (24) of the motor vehicle (10); and the detected test pattern (26, 30) is compared with a specified reference pattern by an analyzing device (28) of the motor vehicle (10). The invention further 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 according to the preamble of claim 1 . 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 t...
