- the invention thus provides, inter alia, a commissioning and parameter plausibility of a hygro- trostatically actuated dual-clutch system in the service.
- Parameters can be initially determined via a commissioning routine, after which several coupling ramps can be run with the adaptation switched on and at the end of the ramps, a long-term touch point can be set to a then adapted short-term touch point.

- the clutch parameters may be learned after the first clutch position ramp, this may correspond to the startup routine. Due to the ramps, the short-term touch points and the clamping force stiffness can change. At the end of the coupling ramps, the long-term tactile point can be set to the short-term tactile point.
