Abstract

Bei einem Verfahren zur Vermeidung von Ruckelschwingungen beim Beschleunigen von Kraftfahrzeugen wird das Motormoment verändert.In a method for avoiding jerky vibrations in the Accelerating motor vehicles changes the engine torque.

Um Ruckelschwingungen ohne Beeinträchtigung des Beschleunigungsverhaltens und des Abgasverhaltens zuverlässig zu verhindern, ist vorgesehen, daß bei Betätigung des Fahrpedals das Motormoment gemäß einem vorgegebenen Motor-Momentenverlauf zwischen einem unteren Momentenwert und einem oberen Momentenwert verändert wird, wobei der Motor-Momentenverlauf benachbart zum unteren Momentenwert ein lokales Maximum und zwischen dem lokalen Maximum und dem oberen Momentenwert ein lokales Minimum aufweist.

Figure 00000001
In order to reliably prevent jerky vibrations without impairing the acceleration behavior and the exhaust gas behavior, it is provided that when the accelerator pedal is actuated, the engine torque is changed between a lower torque value and an upper torque value in accordance with a predetermined engine torque curve, the engine torque curve being adjacent to the lower torque value has a local maximum and a local minimum between the local maximum and the upper torque value.
