摘要:
A method of feeding a clutch cylinder in a hydraulically actuated clutch system in a motor vehicle and a respective hydraulically actuated clutch system are suggested. The clutch system comprises at least one clutch that can be closed by filling the clutch cylinder; and a hydraulic system that provides a system pressure and has a clutch control valve having an inlet and an outlet. A system pressure is applied at the inlet of the control valve; the clutch pressure for actuating the clutch is provided at the outlet; and the system pressure is decreased pressure prior to and during the filling of the clutch cylinder. The decreased system pressure allows a high volume flow and therefore a fast filling of the clutch cylinder without establishing a premature torque transmitting capacity in the clutch.
