Abstract
A method of accelerating decoupling of the starting clutch () that is able to connect the electric machine () to the transmission input in a hybrid drive-train of a motor vehicle, when a decoupling command is issued, at the same time as the regulation of the starting clutch begins for the purpose of decoupling the starting clutch () or a specified time after the regulation of the starting clutch begins. The electric machine is regulated in such manner that a torque is built up such that the transition to sliding friction, and thus decoupling and the onset of slip, are sped up while maintaining the nominal driving torque.
