Abstract
A method for setting the engagement point of a friction clutch of a multi-step transmission for a motor vehicle. The friction clutch can be activated, controlled, by means of a clutch actuator. A set point value of the clutch actuator is set for the engagement point of the friction clutch as a function of a time profile of a physical variable which occurs starting from a transition state after activation of the friction clutch to a transition value. An electric machine is connected to the multi-step transmission. Influencing of the multi-step transmission by the electric machine is taken into account in the setting of the engagement point of the friction clutch.

Method for setting an engagement point of a friction clutch of a multi-step transmission for a motor vehicle, wherein the method is performed by a control device of the multi-step transmission, wherein the friction clutch can be activated, controlled, utilizing a clutch actuator, wherein a set point value of the clutch actuator is set for the engagement point of the friction clutch as a function of a time profile of a physical variable which occurs starting from a transition state after activation of the friction clutch to a predefined transition value,
- wherein an electric machine is fixedly connected to the multi-step transmission, and wherein influencing of the multi-step transmission by the electric machine is taken into account in the setting of the engagement point of the friction clutch.
