Method for accelerating the decoupling of a starting clutch, which releasable connects an electric machine to a transmission input, in a hybrid drive train of a vehicle
First Claim
1. A method of accelerating decoupling of a starting clutch (5) that releasably connects an electric machine (2) to a transmission input in a hybrid drive-train of a motor vehicle, the method comprising the steps of:
- regulating the electric machine (2), when a decoupling command is issued, at the same time as regulation of the starting clutch begins for the purpose of decoupling the starting clutch (5) or a specified time after the regulation of the starting clutch begins, in such a manner that a torque is built up, whereby a transition to sliding friction, and thus the decoupling, are sped up while still maintaining a nominal driving torque.

Abstract
A method of accelerating decoupling of the starting clutch (5) that is able to connect the electric machine (2) 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 (5) 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.
