Abstract
A method for controlling or regulating a clutch torque of a startup clutch of a motor vehicle, which first of all reliably prevents an unintentional rolling of the motor vehicle down a gradient and second enables a comfortable maneuvering mode, which requires no separate actuation of an operating element for activating a maneuvering mode, and also enables a precisely dosed speed definition during maneuvering on gradients, wherein the adjusted speed is substantially independent from the gradient of the ground and the motor vehicle load. A startup and maneuvering control device is provided according to the invention, which reads in driving resistance data, determines therefrom a driving resistance value, and determines a base value of the clutch torque of the automated startup clutch in dependence thereof, which is adjusted in dependence upon the accelerator pedal.
