Zusammenfassung:	The invention relates to a system and a method for an electric drive assembly. In one example, an electric drive system is provided that includes two multi-motor drive units having associated planetary gear reducers, the reducers having asymmetric gear ratios. The planetary gear reducer in each drive unit includes a ring gear and a sun gear rotationally coupled to a pair of motors and a carrier rotationally coupled to an output gear cooperating with the gear reducer of the bridge assembly. 本发明涉及用于电动驱动组件的系统和方法。在一个示例中，提供了一种电动驱动系统，该系统包括具有相关联的行星齿轮减速器的两个多电机驱动单元，这些减速器具有不对称的齿轮比。每一个驱动单元中的行星齿轮减速器包括旋转地联接到一对电机的环形齿轮和太阳齿轮以及承载件，该承载件旋转地联接到与桥组件的齿轮减速器配合的输出齿轮。
