  • Patent number: 11174906
    Abstract: A method for operating a clutch of a drive train of a vehicle wherein the clutch, a drive motor primary axis having first wheels that can be driven by the drive motor as first axis and a second axis having second wheels are driven by the drive motor via the clutch as second axis, with the clutch being adjusted between a closed position, wherein a first coupling torque of the clutch is set, and at least one second position differing from the closed position, wherein a second coupling torque of the clutch that is lower than the first coupling torque is set: determining at least one coefficient of friction of a roadway the vehicle is located on; and as a factor of the determined coefficient of friction: adjusting a basic torque of the clutch, with the clutch being prestressed in the second position by the basic torque.
