    摘要: The invention relates to a method for open-loop and/or closed-loop controlling of a wet clutch of a motor vehicle, in particular a dual clutch, wherein a specific clutch torque (MK) is adjusted with the aid of a control device (1), and a specific clutch pressure (PK) is applied to the clutch to adjust this specific clutch torque (MK) and the clutch is operated with a specific clutch slip (nS), wherein the functional dependency of the clutch torque (MK) on the clutch pressure (PK) is defined by at least one clutch characteristic curve (KK) for a specific range, in particular stored in the control device, and wherein the clutch characteristic curve (KK) also inherently has a specific friction value or the stored clutch characteristic curve (KK) is based on an inherent friction value. The driving comfort is improved in that initially a friction value correction factor (RKF) is defined and/or determined according to a desired clutch torque (MKSoll) and/or according to the clutch slip (nS) and/or according to the clutch temperature (T) and/or according to the state of aging of the clutch, a corrected clutch torque (MKSoll-Korrektur) is then determined and/or calculated with the aid of the friction value correction factor (RKF) based on the clutch characteristic curve (KK), the clutch pressure (PKSoll-Korrektur) associated with this corrected clutch torque (MKSoll-Korrektur) is then determined based on the clutch characteristic curve (KK), wherein the corrected clutch pressure (PKSoll-Korrektur) determined in this way is then also adjusted to the clutch.

    摘要: The invention relates to a hydraulic actuation device (10) for a motor vehicle friction clutch (12), comprising: a manually actuatable master cylinder (16), the actuation of which is sensed by a sensor (14) and which has a master pressure chamber (18) which, in a rest position, is fluidically connected to a reservoir (22) by means of a replenishing region (20); a slave arrangement (26) comprising a slave pressure chamber (24) and having a slave cylinder (28) that is functionally connected to said motor vehicle friction clutch; a pressure line (30) which connects the master pressure chamber to the slave pressure chamber and in which an electrically actuatable valve arrangement (38) is connected; a motor pump (32) that is connected, on the input side, to the reservoir and can be connected, on the output side, to the pressure line; and a control unit (40) to which the electrical parts are connected (sensor, valve arrangement, motor pump). The valve arrangement comprises, connected in parallel, an electrically actuatable proportional valve (42) and a first check valve (44) which blocks in the direction of the master pressure chamber, and the motor pump is connected to said pressure line between the valve arrangement and the slave pressure chamber by means of a second check valve (46) that blocks in the direction of the motor pump.
