The invention relates to a method for operating a drive train of a motor vehicle, in which a torque profile (101) that varies over time is transmitted to the drive train, and in the case of a torque step ([Delta] M) of the torque profile (101), a drive train torque profile (102) with damped jounce vibrations is generated in the drive train as a result of the excitation behavior thereof. In order to form the drive train in a robust manner with respect to jolting vibrations in the event of the introduced torque step ([Delta] M), a corresponding control is determined on the basis of an excitation model that simulates the excitation behavior of the drive train and by means of an excitation model by means of a torque filter that selects a torque step that reduces the vibrations from a plurality of possible states, the torque profile (101) is corrected by means of the corresponding control.
本发明涉及一种用于运行机动车的动力总成的方法,其中随时间变化的扭矩变化曲线(101)传递到动力总成上,并且在扭矩变化曲线(101)的扭矩阶跃(ΔM)情况下,在动力总成中由于其激励行为产生附带经衰减的颠簸振动的动力总成扭矩变化曲线(102)。为了在该引入的扭矩阶跃(ΔM)情况下相对于颠簸振动鲁棒地构成动力总成,根据模拟动力总成的激励行为的激励模型和借助于从多个可能的状态中选择出减少振动的扭矩阶跃的扭矩滤波器的激励模型,确定对应控制,借助所述对应控制修正扭矩变化曲线(101)。
