摘要

#CMT# #/CMT# The method involves controlling a starting clutch of a motor vehicle such that a load of an internal combustion engine is reduced by the starting clutch that is to be closed in a slip, when a speed of the combustion engine decreases. A starting process of the vehicle is proceeded by closing the clutch, when the engine speed is stabilized and/or increased. A coupling torque (M) is lowered around a value during decrease of the engine speed, where the value is dependent on steepness of the decrease of the engine speed. #CMT#USE : #/CMT# Method for preventing stalling of a drive motor during a starting process of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The method enables stabilization of the engine speed during starting of the motor vehicle by an engine torque and by reduction of the coupling torque without the risk of an unstable control loop. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graphical representation of course of the engine speed and of the torque at the starting clutch with respect to time. A : Engine speed course C : Engine speed gradient D : Reference deviation of engine speed M : Coupling torque n-soll : Reference speed of engine t : Time.
