Method for controlling a separating clutch of a drive assembly of a vehicle and/or a machine, in particular a hybrid drive train of a motor vehicle, wherein an internal combustion engine can be connected in a non-positive manner to a drive train by closing the separating clutch, wherein the internal combustion engine can be operated with an engine torque (M VKM) and/or provides an engine torque (M VKM), characterized in that - in the presence of a closing request for closing the separating clutch a clutch torque (M K) is determined, in particular calculated, depending on the engine torque (M VKM) applied and/or provided then and depending on a constant transmission factor (i VKM-K) existing between the internal combustion engine and the separating clutch, and the separating clutch is closed with a closing pressure (p) for realizing the determined clutch torque (M K), - wherein the closing pressure (p) is determined on the basis of the determined clutch torque (M K) and a clutch torque closing pressure characteristic curve, and the separating clutch is closed with the determined closing pressure (p) for realizing the determined clutch torque (M K), - wherein, for adapting the clutch torque closing pressure characteristic curve, the separating clutch is opened starting from a closed state with excess contact pressure by reducing the closing pressure until at least a specific differential rotation speed (n an -n ab) between a drive-side rotation speed (n an) of the separating clutch and an output-side rotation speed (n ab) of the separating clutch is reached and the closing pressure (p) and the engine torque (M VKM) are determined at the at least one specific differential rotation speed (n an -n ab), wherein then the clutch torque associated with the closing pressure (p) determined in the above manner is re-determined, in particular recalculated, from the engine torque (M VKM) determined in the above way by multiplication with the constant transmission factor (i VKM-K), and using the resulting value (M VKM *i VKM-K) the old clutch torque associated with the determined closing pressure (p) is adapted, in particular corrected, in the clutch torque closing pressure characteristic curve. - in the presence of a closing request for closing the separating clutch a clutch torque (M K) is determined, in particular calculated, depending on the engine torque (M VKM) applied and/or provided then and depending on a constant transmission factor (i VKM-K) existing between the internal combustion engine and the separating clutch, and the separating clutch is closed with a closing pressure (p) for realizing the determined clutch torque (M K), - wherein the closing pressure (p) is determined on the basis of the determined clutch torque (M K) and a clutch torque closing pressure characteristic curve, and the separating clutch is closed with the determined closing pressure (p) for realizing the determined clutch torque (M K), - wherein, for adapting the clutch torque closing pressure characteristic curve, the separating clutch is opened starting from a closed state with excess contact pressure by reducing the closing pressure until at least a specific differential rotation speed (n an -n ab) between a drive-side rotation speed (n an) of the separating clutch and an output-side rotation speed (n ab) of the separating clutch is reached and the closing pressure (p) and the engine torque (M VKM) are determined at the at least one specific differential rotation speed (n an -n ab), wherein then the clutch torque associated with the closing pressure (p) determined in the above manner is re-determined, in particular recalculated, from the engine torque (M VKM) determined in the above way by multiplication with the constant transmission factor (i VKM-K), and using the resulting value (M VKM *i VKM-K) the old clutch torque associated with the determined closing pressure (p) is adapted, in particular corrected, in the clutch torque closing pressure characteristic curve.
