Abstract

Vorgestellt wird ein Verfahren zur Steuerung eines Verbrennungsmotors (12) in einem Triebstrang (10), der einen hydraulischen Drehmomentwandler (14) mit einem Pumpenrad (16) und einem Turbinenrad (18) aufweist, bei einem Übergang von einem Schiebebetrieb in einen Zugbetrieb. Das Verfahren zeichnet sich dadurch aus, dass die Drehzahlen (n_1) des Pumpenrades (16) und (n_2) des Turbinenrades (18) zeitgleich erfasst und miteinander verglichen werden, eine Abweichung (dn) der Drehzahl (n_1) des Pumpenrades (16) von der Drehzahl (n_2) des Turbinenrades (18) ermittelt wird, und dann, wenn die Drehzahl (n_2) des Turbinenrades (18) größer als die Drehzahl (n_1) des Pumpenrades (16) ist und die Abweichung (dn) einen vorgegebenen Schwellenwert (S) unterschreitet, das Drehmoment des Verbrennungsmotors (12) in Abhängigkeit von der Abweichung (dn) und einer Änderungsgeschwindigkeit (d/dt(n_1)) der Drehzahl (n_1) des Pumpenrades (16) eingestellt wird. Ferner wird ein Steuergerät (32) vorgestellt, das zur Durchführung eines solchen Verfahrens eingerichtet ist.

A method is presented for controlling an internal combustion engine (12) in a drive train (10) having a hydraulic torque converter (14) with a pump wheel (16) and a turbine wheel (18) at a transition from a coasting operation to a traction operation. The method is characterized in that the rotational speeds (n_1) of the impeller (16) and (n_2) of the turbine wheel (18) are simultaneously detected and compared with each other, a deviation (dn) of the rotational speed (n_1) of the impeller (16) the rotational speed (n_2) of the turbine wheel (18) is determined, and when the rotational speed (n_2) of the turbine wheel (18) is greater than the rotational speed (n_1) of the impeller (16) and the deviation (dn) reaches a predetermined threshold value ( S), the torque of the internal combustion engine (12) in dependence on the deviation (dn) and a rate of change (d / dt (n_1)) of the rotational speed (n_1) of the impeller (16) is set. Furthermore, a control unit (32) is presented, which is set up to carry out such a method.
