Abstract:
(EN) The invention relates to a device (100) for a vehicle. Said device comprises a detector arrangement (110), which is designed to detect a vertical position change of a vehicle driving ahead, and a control unit (120), wherein the vertical position change of the vehicle driving ahead is caused by a roadway unevenness which is driven over. The control unit (120) is designed to conclude that there is a significant roadway unevenness if the vertical position change of the vehicle driving ahead exceeds a predefined threshold and occurs within a predefined time span.
(FR) L'invention concerne un dispositif (100) pour un véhicule. Ledit dispositif comprend un ensemble de détection (110), qui est conçu pour détecter une modification de position verticale d'un véhicule précédent, et un appareil de commande (120), la modification de position verticale du véhicule précédent étant provoquée par une irrégularité de la chaussée parcourue. L'appareil de commande (120) est conçu, lorsque la modification de position verticale du véhicule précédent dépasse une valeur seuil prédéfinie et est réalisée pendant un laps de temps prédéfini, pour conclure à une irrégularité importante de la chaussée.
(DE) Die Erfindung betrifft eine Vorrichtung (100) für ein Fahrzeug. Diese weist eine Detektoranordnung (110), die ausgeführt ist, eine vertikale Positionsänderung eines vorausfahrenden Fahrzeuges zu detektieren, und ein Steuergerät (120) auf, wobei die vertikale Positionsänderung des vorausfahrenden Fahrzeugs durch eine überfahrene Fahrbahnunebenheit hervorgerufen wird. Das Steuergerät (120) ist ausgeführt, wenn die vertikale Positionsänderung des vorausfahrenden Fahrzeugs einen vordefinierten Schwellwert überschreitet und innerhalb einer vordefinierten Zeitspanne erfolgt, auf eine signifikante Fahrbahnunebenheit zu schließen.
