Abstract
An apparatus for recognizing road conditions, for use especially in a motor vehicle, includes an infrared transmitter-receiver system. Devices are provided which make it possible to separate signal fractions into different infrared wavelength ranges. This allows for the reliable evaluation of the conditions of the road section being monitored, using a simple and economical device. The infrared devices may be combined with a microwave device.
