An electric propulsion system (S) comprising a first propulsion line (L1) and a second propulsion line (L2) operably individually connected to a common drive shaft (X), each propulsion line comprising an electric motor (M1, M2), a gearbox (G1, G2) comprising at least two gear ratios (1, 2), a clutch (C1, C2) connecting/disconnecting the associated propulsion line with/from the drive shaft (X). A processing device (ECU) is configured to control the following operations: first in a propulsion line whose maximum transmittable torque is lower and at the end of the change in the transmission ratio, the torque transmission and subsequent change in the transmission ratio are interrupted, and in another propulsion line, the torque transmission and subsequent change in the transmission ratio are interrupted.

    一种电力推进系统(S),其包括可操作地单独连接到公共驱动轴(X)的第一推进线(L1)和第二推进线(L2),每个推进线包括电动机(M1、M2)、变速箱(G1、G2)、离合器(C1、C2),该变速箱包括至少两个齿轮比(1档、2档),该离合器将相关的推进线与驱动轴(X)连接/断开。处理装置(ECU)被配置为控制以下操作:首先在其最大可传递扭矩较低的推进线中且在传动比的改变结束时,中断扭矩传递和传动比的随后改变,在另一推进线中,中断扭矩传递和传动比的随后改变。
