1. A method, performed by a control device, for driving at least one power consumer connected to a powertrain of a vehicle, the powertrain comprising at least one propulsion unit and a gearbox, the gearbox comprising:
a first main shaft;
a second main shaft;
an output shaft of the gearbox connected to drive wheels of the vehicle;
a lay shaft connected to the first main shaft, the second main shaft and the output shaft of the gearbox;
a first gear pair connected to the first main shaft and the lay shaft;
a second gear pair connected to the second main shaft and the lay shaft;
wherein the at least one propulsion unit comprises a first electrical machine and a second electrical machine, wherein the first electrical machine is connected to the first main shaft and the second electrical machine is connected to the second main shaft;
wherein a connection shaft is connected to the first electrical machine; and
wherein the at least one power consumer comprises a first power consumer connected to the first main shaft and/or a second power consumer connected to the connection shaft, wherein the gearbox further comprises a first planetary gear connected to the first main shaft; a second planetary gear connected to the first planetary gear and the second main shaft, wherein the first electrical machine is connected to the first main shaft via the first planetary gear, and the second electrical machine is connected to the second main shaft via the second planetary gear;
the method comprising:
controlling the powertrain to provide uninterrupted propelling torque on the first main shaft and/or on the connection shaft when the vehicle is in a stand still condition of the output shaft of the gearbox;
the method further comprising at least one of:
controlling the powertrain to provide uninterrupted propelling torque on the first main shaft and/or on the connection shaft when the vehicle is in a transition from a stand still condition to a rotational condition of the output shaft of the gearbox; or
controlling the powertrain to provide uninterrupted propelling torque on the first main shaft and/or on the connection shaft when the vehicle is shifting from one gear to another gear in the gearbox.
