Abstract
A sensor arrangement for capturing the coefficient of friction from a roadway surface, wherein the sensor arrangement is arranged on a motor vehicle and includes at least one radiation emitter unit and at least one electronic evaluation circuit, wherein the radiation emitter unit emits electromagnetic radiation toward the roadway surface and the radiation is at least to some extent reflected and/or scattered at the roadway surface and the reflected and/or scattered radiation is at least to some extent captured in the radiation emitter unit and/or in one or more additional sensor units, wherein the electronic evaluation circuit is designed such that it ascertains a piece of coefficient-of-friction information for the roadway surface from the intensity of the reflected and/or scattered radiation or a variable which is dependent thereon.
