Methods and systems are provided for an electric driveline. In one example, the electric driveline includes an electric drive unit having a planetary gear set including a first gear set component rotatably coupled to a first electric machine and a second electric machine. The electric drive unit additionally includes: an output shaft rotationally coupled to a second gear set component of the planetary gear set; a first friction clutch configured to selectively brake a third gear set component of the planetary gear set; and a second friction clutch configured to selectively couple the first gear set component to the output shaft.

    提供了用于电动传动系的方法和系统。在一个示例中,该电动传动系统包括具有行星齿轮组的电驱动单元,该行星齿轮组包括旋转地联接到第一电机和第二电机的第一齿轮组部件。该电驱动单元附加地包括:输出轴,该输出轴旋转地联接到该行星齿轮组中的第二齿轮组部件;第一摩擦式离合器,该第一摩擦式离合器构造成选择性地制动该行星齿轮组中的第三齿轮组部件;以及第二摩擦式离合器,该第二摩擦式离合器构造成选择性地将第一齿轮组部件联接到输出轴。
