A method for determining a characteristic curve of a clutch of a clutch actuation system in a drive train, in particular a motor vehicle.

摘要

The invention relates to a method for determining a characteristic curve of a clutch of a clutch activation system in a drivetrain, in particular of a motor vehicle, in which the clutch is activated by an actuator, wherein a bite point of the clutch is adapted as a first support point of the characteristic curve. In a method in which the accuracy of the specific clutch characteristic curve is improved, a preload point of the actuator, preferably of an electric central disengagement device, is used as a second support point of the characteristic curve.
