Abstract
(DE)
Vorgeschlagen werden ein Verfahren zur Erzeugung eines Ansteuersignals (15) für ein Fahrzeug (1), wobei zu einem von dem Fahrzeug (1) zu befahrenden Streckenabschnitt Fahrbahninformationen, umfassend Fahrbahnsteigung (12) und Reibwert (13), erhalten werden, dadurch gekennzeichnet, dass Fahrzeugparameter (14) erhalten werden, dass aus den erhaltenen Fahrbahninformationen (12, 13) und den Fahrzeugparametern (14) die Höhe eines Risikos für ein Rutschen, insbesondere Abrutschen, des Fahrzeugs (1) in oder entgegen Fahrrichtung auf dem Streckenabschnitt bestimmt wird und dass bei Überschreiten eines RisikoGrenzwertes das Ansteuersignal (15) erzeugt wird, eine Vorrichtung zur Durchführung des Verfahrens und ein Computerprogramm.
(EN)
The invention relates to a method for generating an actuation signal (15) for a vehicle (1). Roadway information, comprising a roadway inclination (12) and a friction coefficient (13), is obtained for a route section to be traversed by the vehicle (1). The invention is characterized in that vehicle parameters (14) are obtained, the degree of risk of the vehicle (1) skidding, in particular skidding downhill, in or opposite the driving direction on the route section is determined from the obtained roadway information (12, 13) and the vehicle parameters (14), and if a risk threshold is exceeded, the actuation signal (15) is generated. The invention also relates to a device for carrying out the method and to a computer program.
