A method for operating a motor vehicle includes, when a target differential speed is set for a separating clutch (), determining a power transmission factor depending on the target differential speed and an internal combustion engine-driven torque to be transmitted by the separating clutch (). The method also includes determining an actuating pressure for the separating clutch () depending on the power transmission factor, controlling the separating clutch () with the actuating pressure, ascertaining an actual differential speed forming at the separating clutch () depending on the actuating pressure, determining a corrected power transmission factor with a controller () depending on a deviation between the target differential speed and the actual differential speed, determining a corrected actuating pressure for the separating clutch () depending on the corrected power transmission factor and the internal combustion engine-driven torque to be transmitted, and controlling the separating clutch () with the corrected actuating pressure.
