A method for adapting torque characteristic in a disengaging clutch arranged in a vehicle hybrid drive train between an internal combustion engine and an electrical machine connected to a driven wheel, include the following steps: deciding the engine can be disconnected; switching the engine off and opening the clutch; detecting the time gradient of rotational speed of the engine with it switched off and the clutch opened; partially closing the clutch when rotational speed of the engine falls below a predetermined value, and detecting the time gradient of rotational speed of the engine with the clutch partially closed; determining the clutch torque transmitted by the partially closed clutch by evaluating detected time gradients of rotational speed of the engine; and adapting the characteristic of the clutch with the aid of the determined clutch torque transmitted by the partially closed clutch.
