Abstract
(DE)
Die Erfindung geht aus von einem Antiblockierregelsystem für ein Fahrzeug mit wenigstens zwei Achsen, bei dem jedes Rad der Hinterachse wenigstens einen Radsensor zur Messung der Radgeschwindigkeit, eine Bremsdrucksteuereinrichtung sowie Ansteuerkanäle für diese Bremsdrucksteuereinrichtungen aufweist. Wie schon eingangs erwähnt, bestimmt dabei das den niedrigeren Kraftschluß aufweisende Hinterrad (Low-Rad) die gemeinsame Regelung des Bremsdrucks an den Hinterrädern (Select-low-Regelung). Der Kern der Erfindung besteht nun darin, daß der Bremsdruck an der Bremse des den höheren Kraftschluß aufweisenden Hinterrads (High-Rad) gegenüber dem Bremsdruck an dem den niedrigeren Kraftschluß aufweisenden Hinterrad (Low-Rad) erhöht wird.
(EN)
The invention concerns an anti-locking brake control system for for a vehicle with at least two axles, each wheel on the rear axle having at least one sensor for measuring the wheel speed, a brake-pressure control device and control lines to the brake-pressure control devices. The rear wheel with the lower degree of traction (the so-called 'low' wheel) determines the joint control of the brake pressure at the rear wheels (select low control). The central idea of the invention is that the pressure at the brake on the wheel with the higher degree of traction (the 'high' wheel) is increased relative to the pressure at the brake on the wheel with the lower degree of traction (the 'low' wheel).
(FR)
L'invention concerne un système de régulation antiblocage pour un véhicule comportant au moins deux essieux. Chaque roue de l'essieu arrière comporte au moins un détecteur de vitesse sur roue destiné à mesurer la vitesse de rotation de la roue, un dispositif de régulation de la pression de freinage, ainsi que des canaux de commande d'amorçage pour ces dispositifs de régulation de la pression de freinage. La roue arrière qui présente l'adhérence la plus faible ('low wheel') détermine par conséquent la régulation commune de la pression de freinage transmise aux roues arrière (régulation-'select low'). L'invention se caractérise essentiellement en ce que la pression de freinage exercée au niveau des freins de la roue arrière présentant l'adhérence la plus marquée ('high wheel') est augmentée comparativement à celle exercée au niveau de la roue arrière présentant l'adhérence la plus faible ('low wheel').
