Method to judge condition of roadway in advance

The method involves detecting roadway surface irregularities in the travel direction (F) of at least one wheel (5,6). The irregularities are detected by a scanning system (1,2), and are converted to signals, for the active control of vehicle sets. The method involves transmitting a geometrically det...

Beschreibung
Zusammenfassung:	The method involves detecting roadway surface irregularities in the travel direction (F) of at least one wheel (5,6). The irregularities are detected by a scanning system (1,2), and are converted to signals, for the active control of vehicle sets. The method involves transmitting a geometrically determined light pattern (7-9) in the direction of a roadway surface section (3.1,3.2) at a distance in front of the front wheels. A light image is determined by a camera, with the light image containing the roadway surface section, from which the transmitted light pattern is reflected. The detected photographic image is evaluated, with the geometry of the reflected light pattern being the basis for the forming of the signal representing the condition of the roadway surface. Preferably, incoherent light is used for the pulsed transmission.
