Abstract
In a method for delivering a warning of a hazardous road surface state for application in a travelling motor vehicle in which the air temperature is measured, a targeted prediction of the road surface state is to be made so that the output of a warning can be avoided in many cases in which such a warning was not objectively justified. This is achieved by means of a contactless measurement method by which means the moisture of the road surface is determined and by means of which the temperature of the road surface is determined where a value describing the road surface state is determined taking into account these three measured values. The warning is then delivered depending on the value describing the road surface state.
