    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.

    摘要: A method for determining the filling pressure for a clutch and a hydraulic clutch adapted to conduct said method are suggested where clutch linings are brought into engagement against the force of a clutch release spring by a hydraulic pressure system. The hydraulic pressure is controlled such that an engagement point where the clutch linings abut against each other but without establishing a torque transmitting capacity in the clutch can be reached quickly and precisely. The purpose is to achieve a short gear shifting time, but at the same time avoid impacts due to premature torque transmittal capacity in the clutch during gear shifting. A precision shifting mode or a fast shifting mode can be established, compromising speed and torque transmitting capacity depending on the preferred driving mode.
