<p>The method involves applying a preset-filling-pressure to a pressure system, and determining actual pressure in the system. The application of the preset-filling-pressure is terminated when the actual pressure has reached a threshold-turnoff-pressure. The system is applied with a preset-abutting-pressure holding an engagement point of a clutch. A characteristic, indicating whether the actual pressure is above or below the preset-abutting-pressure after a time point, is determined. The preset-filling-pressure is changed repeatedly until process terminating criterion is fulfilled, and is stored.</p> |
