Method for controlling an automated friction clutch in a motor vehicle drivetrain during a starting process

Abstract

Method for controlling an automated friction clutch in a drivetrain of a motor vehicle during a starting process with an internal combustion engine controlled by an accelerator pedal to a driver-requested torque and a transmission as well as an engine speed controller, which sets a control variable for the clutch torque transmissible via the friction clutch on the basis of a target speed such that, depending on an accelerator pedal position, a ratio between an engine speed of the internal combustion engine and a transmission input speed of the transmission is adjusted until an identity of engine speed and transmission input speed is reached.wherein the target speed is corrected by means of a correction parameter dependent on a slip gradient of the friction clutch, wherein the correction parameter is determined in each case over a repeating control interval from a current clutch slip, a target slip gradient determined and a transmission input acceleration.
