Abstract

In a method for magnifying torque during driveaway of a motor vehicle using a clutch, the driver-selected torque is dynamically magnified in time, and the enhancement component then is reduced down to 0 at increasing vehicle speed as a function of the latter. The driveaway behavior of a vehicle may be perceptibly improved, and an unintended shutoff of the internal combustion engine may be largely prevented when the accelerator pedal is operated too weakly or the clutch is engaged too fast.
