Abstract:
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.
