The invention relates to a method for operating a drive train (1) of a working machine, wherein a traction drive (8) of the drive train (1) is driven by an electric traction motor (2) via a transmission (4) and when a gear stage of the transmission (8) is changed, the rotational speed of the traction motor (2) is synchronised with the gear stage being engaged. The method according to the invention is characterised in that a computational model of the traction motor (2) is used for the rotational speed synchronisation, which model, taking into account a moment of inertia of the traction motor (2), describes a torque to be delivered for the rotational speed synchronisation. The invention further relates to a corresponding drive train (1) and to a working machine.
本发明涉及一种用于操作工作机器的驱动系(1)的方法,其中驱动系(1)的牵引驱动器(8)由电动牵引马达(2)经由变速器(4)驱动,并且其中,当变速器(8)的齿轮级变化时,牵引马达(2)的转速与正被接合的齿轮级同步。根据本发明的方法的特征在于,牵引马达(2)的计算模型用于转速同步,该模型考虑了牵引马达(2)的转动惯量,描述了将被传递的用于转速同步的扭矩。本发明进一步涉及一种对应的驱动系(1)并且涉及一种工作机器。
