Abstract
(DE)
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Betreiben eines Fahrzeugs (100), bei dem eine einen Reibwert einer Straße im Bereich des Fahrzeugs (100) repräsentierende Straßenzustandsinformation (106) von einem Ultraschallsensorsystem (104) des Fahrzeugs (100) eingelesen wird und eine Haftgrenze (112) zumindest eines Rads des Fahrzeugs (100) unter Verwendung der Straßenzustandsinformation (106) bestimmt wird, wobei ein Ansprechverhalten des Fahrzeugs (100) unter Verwendung der Haftgrenze (112) beeinflusst wird.
(EN)
The present invention relates to a method for operating a vehicle (100), in which road condition information (106) representing a coefficient of friction of a road in the region of the vehicle (100) is read in by an ultrasound sensor system (104) of the vehicle (100) and an adhesion limit (112) of at least one wheel of the vehicle (100) is determined using the road condition information (106), wherein a response behaviour of the vehicle (100) is influenced using the adhesion limit (112).
(FR)
L'invention concerne un procédé pour faire fonctionner un véhicule (100) selon lequel une information d'état de la route (106) représentant un coefficient de frottement d'une route dans la zone du véhicule (100) est lue par un système ultrasonore (104) du véhicule (100), et une limite d'adhérence (112) d'au moins une roue du véhicule (100) est déterminée sur la base de l'information d'état de la route (106), une réponse du véhicule (100) étant infuencée au moyen de la limite d'adhérence (112).
