Abstract
A method is provided for moving off of a vehicle with a hybrid powertrain, comprising a combustion engine; a gearbox with input and output shafts; a first planetary gear connected to the input shaft and a first main shaft; a second planetary gear connected to the first planetary gear and a second main shaft; first and second electrical machines respectively connected to the first and second planetary gears and capable of operating each other; one gear pair connected with the first planetary gear and output shaft; and one gear pair connected with the second planetary gear and output shaft. The method comprising, while the combustion engine is in operation: a) ensuring that the rotatable components of the first and second planetary gears are respectively disconnected from each other, b) ensuring that at least one gear is engaged, corresponding to the one gear pair connected with the first planetary gear, and/or the one gear pair connected with the second planetary gear, and c) activating the first and second electrical machines, where total power output from the electrical machines is zero, and so that a torque is generated in the output shaft.
