METHOD FOR ACTIVELY CHANGING THE FRICTIONAL VALUE OF A HYBRID DISCONNECT CLUTCH INSTALLED IN A POWER TRAIN OF A VEHICLE

A method actively changes the frictional value of a hybrid disconnect clutch installed in a powertrain of a vehicle in which a first electric motor () is connected to a clutch input () and an internal combustion engine (), and a second electric motor () is connected to a clutch output () and a vehicle output (). The frictional value of the hybrid disconnect clutch is actively changed, in order to roughen a surface of the friction linings on the hybrid disconnect clutch (). A slip situation is established at the hybrid disconnect clutch (), and during this slip situation energy is introduced into the hybrid disconnect clutch () in a controlled manner.
