A method for adjusting the point of engagement of a friction clutch of a step-variable transmission for a motor vehicle, in particular a friction clutch of a dual clutch transmission. The friction clutch is controllably actuated by means of a clutch actuator and at least one synchronizer shifting clutch is controllably actuated by means of a shift actuator for the engagement and disengagement of a gear ratio of the spur-gear transmission. A set-point of the clutch actuator for the point of engagement of the friction clutch is adjusted as a function of a speed gradient value, which ensues from a transitional state with the friction clutch actuated and the shifting clutch actuated, once the shifting clutch is opened. The transitional state is established by setting the clutch actuator and the shift actuator to a respective transitional value substantially at the same time or, at least in sections, in parallel. |
