Abstract

Official abstract text for this publication.

An apparatus, method and computer for actuating a disconnect clutch which is arranged between a first drive unit and a second drive unit of a hybrid drive and which can be actuated by means of a hydraulic actuating element in order to couple or decouple the first drive unit to or from the rest of a powertrain. This is accomplished by adapting a transmission hydraulic pressure level to a disconnect clutch hydraulic pressure level required for actuating the disconnect clutch by a pressure converter arranged between the actuating element and a hydraulic medium supply for a transmission.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus for actuating a disconnect clutch arranged between a first drive unit and a second drive unit of a hybrid drive, the disconnect clutch being hydraulically actuatable in order to one of couple and decouple the first drive unit one of to and from the rest of a powertrain, the apparatus comprising: an actuating element for hydraulically actuating the disconnect clutch; and a pressure converter arranged between the actuating element and a hydrauli…
