Abstract
A method is proposed for controlling a through-connection clutch of a vehicle, in which an interlocking portion of the clutch is opened when the drive-train is virtually free from torque, a shifting operation is then carried out, and after the shifting operation the clutch is closed again. According to the invention, the torque transmitted by the interlocked connection in the clutch is influenced by controlling the motor in order to produce a torque-free condition at the interlocked connection in the clutch, in such manner that the interlocked connection is pre-stressed before the torque-free condition has been reached and separated immediately only when the torque-free condition is reached.
