Ein kritischer Fall ist, wenn bei ABS-Betrieb auf Eis der BKV ausfällt und anschließend ein positiver μ Sprung bei der Bremsung stattfindet. In diesem Fall ist in den Bremskreisen ein niedriger Druck im Grenzfall 1–2 bar, so dass der Anfangsbereich der Druckvolumenkennlinie beim Aussteuerpunkt des Wegsimulators mit ca. 40% Pedalweg beginnt, was zugleich einen Kolbenweg und damit Volumenverlust darstellt.A critical case is when the BKV fails during ABS operation on ice and then a positive μ jump occurs during braking. In this case, in the brake circuits, a low pressure in the limit of 1-2 bar, so that the initial range of the pressure volume characteristic begins at the Aussteuerpunkt the travel simulator with about 40% pedal travel, which also represents a piston stroke and thus volume loss.
Bei Systemen bei der der DK-Kolben
Bezüglich der Diagnose der funktionsrelevanten Komponenten kann das System auch zumindest eine kraftschlüssige Kupplung aufweisen, wie oben beschrieben. Die erste kraftschlüssige Kupplung vorzugsweise mit einem Permanentmagneten in einem Magnetgehäuse eingebettet, wirkt auf ein Polstück der Spindel. Diese Kupplung ist einerseits notwendig, dass durch die Kupplungskraft insbesondere bei kleinen Drucken die Kolbenrückstellung über die Spindel verstärkt wird. Die zweite Kupplung wirkt am vorderen Ende des Übertragungsstößels, welcher über das Magnetgehäuse fest mit dem Kolben verbunden ist. Auch diese kraftschlüssige zweite Kupplung ist vorzugsweise mit einem Permanentmagneten aufgebaut. Zwischen dem Pol und Übertragungsstößel ist ein kleiner Leerweg vorgesehen, der u. a. für die Pedalcharakteristik und Kalibrierung der Pedalwegsensoren gebraucht wird. Zu weiteren Merkmalen und der Wirkungsweise dieser Kupplungseinrichtung wird auf die o. g. deutsche Patentanmeldung
