摘要：An optical device for motor vehicles, designed to detect the condition of theroad surface, comprises a unit for the emission of electromagnetic radiation in the

direction of the road surface to be detected, a receiving unit coupled to an opticalelement for focusing the radiation back-diffused by the road surface and an electroniccontrol and processing unit for receiving signals at output from said receiving unit and forprocessing them in order to determine the condition of the road surface, on the basis ofa reference map. Appearing in said map are the values of the intensity of radiation Iback-reflected at a reference wavelength and at least one second wavelength. The map isdivided into subareas identified beforehand as corresponding to the different conditionsof the road surface.
