Abstract

In dem Betriebszustand des Leerlaufs wird ein erster Drehmomentbeitrag (TQ_1_PD) ermittelt und zwar aus einem ersten Kennfeld (KF1) abhängig von der zeitlichen Ableitung (N_GRD) der Drehzahl und einer Differenz zwischen dem Istwert (N_AV) der Drehzahl und einem vorgegebenen Sollwert (N_SP) der Drehzahl. Ein Sollwert (TQ_IS_SP) des Drehmoments an der Kupplung wird aus dem ersten Drehmomentbeitrag (TQ_1_PD) und abhängig von mindestens einer Betriebsgröße der Brennkraftmaschine ermittelt. Ein Stellsignal für mindestens ein Stellglied der Brennkraftmaschine wird aus dem Sollwert (TQ_IS_SP) des Drehmoments abgeleitet.

Figure 00000001
In the operating state of idling, a first torque contribution (TQ_1_PD) is determined, specifically from a first map (KF1) depending on the time derivative (N_GRD) of the speed and a difference between the actual value (N_AV) of the speed and a predetermined target value (N_SP) the speed. A setpoint (TQ_IS_SP) of the torque on the clutch is determined from the first torque contribution (TQ_1_PD) and depending on at least one operating variable of the internal combustion engine. An actuating signal for at least one actuator of the internal combustion engine is derived from the setpoint (TQ_IS_SP) of the torque.
