Abstract:
1. A method of controlling a through-connection clutch of a vehicle, the through-connection clutch being designed as a friction clutch during a slipping phase and, in phases when slipping of the through-connection clutch is undesired, motor torque being transmitted, between a motor and a transmission, by an interlocked connection, the method comprising the steps of: in the method for controlling the through-connection clutch, an interlocking portion of the through-connection clutch is opened when a drive-train of the vehicle is virtually free from torque, then carrying out a shifting operation, and after the shifting operation, the through-connection clutch is again engaged, wherein a torque transmitted by the interlocked connection in the through-connection clutch is influenced by controlling the motor such that at the interlocked connection in the through-connection clutch, freedom from torque is reached and, before a point of freedom from torque is reached, pre-stressing the interlocked connection in the through-connection clutch by a disengagement force and immediately opening when a point of freedom from torque is reached.
