Vorrichtung und Verfahren zur Vibrationsdämpfung in einer Antriebsanordnung für Kraftfahrzeuge

摘要

A method for and apparatus for preventing oscillations of a vehicle. The engine speed is monitored and filtered, the filtered engine speed being compared to a natural frequency of the vehicle. The natural frequency corresponds to a gear ratio of the vehicle. A torque command is provided to an electric machine (28) coupled to a driveline (16) of the vehicle, the electric machine provides a counteracting torque to the driveline in order to eliminate oscillations in the vehicle.
