A method for controlling a torque transfer device for a vehicle may include identifying a self-locking state of the torque transfer device. The method further may include determining a drivetrain unlocking torque necessary to unlock the torque transfer device in response to identifying the self-locking state. The method further may include determining a drivetrain compensation torque necessary to counteract a drivetrain unlocking torque dynamic effect of the drivetrain unlocking torque in response to identifying the self-locking state. The method further may include applying the drivetrain unlocking torque and the drivetrain compensation torque using one or more drivetrain components of the vehicle in response to identifying the self-locking state.
