WAYS OF ADAPTING TO TYRE ROAD ADHESION, CARRIAGEWAY WIDTH AND WIND FORCE IN THE SYSTEM DRIVER-VEHICLE-ROAD

DIE ANPASSUNGSMOEGLICHKEITEN AN KRAFTSCHLUSS, FAHRBAHNBREITE UND WINDSTAERKE IM SPURREGELKREIS FAHRER - FAHRZEUG - STRASSE

Mathematical investigations of the system driver-vehicle-road show that even a very alert and optimally reactive driver on a very smooth carriageway requires a greater width of road for corrections of course than under normal road conditions. Optimal reactions, i.e. Reaction within the narrow tolerance band of perception limited by stability and the reduced adhesion, requires the driver to have accurate knowledge of the altered vehicle behaviour compared with normal conditions. Reduced speeds to maintain control of the vehicle requires recognition of severe loss of adhesion by the driver on the basis of the visual impression of the road surface so far in advance as to permit timely application of the brakes. /TRRL/
