  The invention relates to a vehicle utilizing a LiDAR sensor system for driver assistance systems. A composition consisting of a thermoplastic material based on polycarbonate is used here for forming the substrate layer of a cover for the sensor with respect to the surroundings. The cover has a specific topcoat layer in order to achieve high abrasion resistance and weathering stability.

  The invention relates to opaque colored multilayer articles having a substrate layer based on polycarbonate or polymethylmethacrylate. The compositions of the substrate layer contain a titanium dioxide having particular properties as white pigment. Compared to the Kronos® 2230 white pigment which is conventionally used as white pigment for corresponding compositions and has more particularly been specially matched to polycarbonate, it is possible to achieve considerably higher weathering stability of the colored shaped bodies provided that a UV absorber-containing coating has been applied to the substrate layer. Color stability and gloss are maintained even after weathering, and brilliant colors can thus be assured.

  A sensor system comprises a LiDAR unit, a camera for visible light and a cover through which light arrives at the LiDAR unit and the camera. The cover comprises a layer containing dyes. The light transmission of the cover in the range from 380 nm to 780 nm is 3% to 25% and in the range from 380 nm to 1100 nm is 40% or more. The attenuation of the LiDAR signal by the cover is such that at least 65% of the original signal intensity reaches the LiDAR detector. The layer containing dyes contains a composition comprising i) at least 70% by weight of a transparent thermoplastic polymer, ii) at least one green and/or red dye and iii) at least one red and/or violet dye. The product of the sum of the weight % fractions of dyes ii) and iii) and the thickness of the layer containing dyes is 0.041 to 0.12 wt % mm. Finally, the composition contains 0% to 0.0005% by weight of IR absorbers.

  The present invention relates to fibre composite materials composed of a fibre material and an aromatic polycarbonate-based matrix material and to multilayer composite materials comprising one or more such layers of fibre composite material. The fibre composite material has a pleasing look with stripes that seem naturally formed on a white or coloured background. The fibre layer(s) is/are embedded in the matrix material. The present invention further relates to a process for producing the fibre composite materials and multilayer composite materials and to components, housing components or housings, especially for laptop, notebook or ultrabook covers, comprising such composite materials themselves.
