Beschreibung
Zusammenfassung:	The invention relates to a method and system for an electric drive assembly. In one example, a method for operating an electric drive system is provided that includes coordinating operation of a first electric drive unit and a second electric drive unit based on a first power request. In the system, each of the first and second electric drive units includes planetary gear reducers that transmit power from a pair of motors to a set of axle shafts, and the planetary gear reducers have asymmetric gear ratios. 本发明涉及用于电动驱动组件的方法和系统。在一个示例中，提供了一种用于操作电动驱动系统的方法，该方法包括基于第一动力请求协调第一电动驱动单元和第二电动驱动单元的操作。在该系统中，第一和第二电动驱动单元中的每一个都包括将动力从成对马达传输到成组车桥轴的行星齿轮减速器，并且这些行星齿轮减速器具有不对称的齿轮比。
