  • Patent number: 8328684
    Abstract: A method for controlling a creeping process of a motor vehicle with an internal combustion engine, a torque converter with a pump shell driven by the internal combustion engine and a turbine shell driving an automated transmission and a separation clutch disposed in the torque flow between the internal combustion engine and the torque converter, wherein a creeping process is initiated when a gas pedal for driver control of the internal combustion engine and a brake pedal are not actuated and a driving velocity of the motor vehicle is less than a predetermined value. In order to be able to perform the creeping process with converter slippage and also with slippage of the separation clutch a creep torque transmitted through the separation clutch is adjusted as a function of the slippage of the torque converter for initiating the creeping process and during the creeping process.
