  • Patent number: 9862388
    Abstract: The invention relates to a method for controlling a drivetrain having an internal combustion engine, a dual-clutch transmission, having a first and second sub-transmission having at least one shiftable gear ratio, a first friction clutch disposed between the internal combustion engine and the first sub-transmission and a second friction clutch disposed between the internal combustion engine and the second sub-transmission to provide a drivetrain torque at a transmission output of the dual-clutch transmission by transferring an engine torque adjusted thereto via the friction clutches.
    Type: Grant

  • Patent number: 9809226
    Abstract: The invention relates to a method for controlling a drivetrain having an internal combustion engine controlled dependent on a load demand on a target engine torque and having a dual-clutch transmission with two sub-transmissions, each having a friction clutch positioned operatively between the internal combustion engine and a sub-transmission with a changing maximum transferable clutch torque, wherein a specified clutch torque is set along an actuation travel path by means of a clutch actuator, a clutch characteristic of the transferable clutch torque is continuously adapted over the actuation travel path, and a maximum engine torque for a sub-transmission, which is reduced in comparison to the target engine torque, is limited to the maximum clutch torque transferable by means of the friction clutch of that sub-transmission.

  • Publication number: 20120316742
    Abstract: The invention relates to a method for controlling a friction clutch, or two friction clutches provided in a double clutch transmission, for transmitting torque provided by an internal combustion engine to a transmission in a motor vehicle. A clutch actuator friction locks friction linings of the friction clutch in an operating mode by specifying an actuation path to transmit the torque provided by the internal combustion engine and to compensate for an extended additional path in the friction clutch from the wear of the friction linings in that the clutch actuator specifies the extended shift travel in comparison to the actuation path, wherein an adjusting process is triggered with compensation for the additional path when wear of the friction clutch exists. To regularly execute in the adjusting process, it is proposed to initiate the shifting path depending on a distance traveled by the motor vehicle since a previous adjusting process.
