1. A method to start a combustion engine in a hybrid powertrain, comprising a gearbox with an input shaft and an output shaft; 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; a first electrical machine, connected to the first planetary gear; a second electrical machine, connected to the second planetary gear; at least one gear pair, connected with the first main shaft, and therefore with the first planetary gear and the output shaft; and at least one gear pair, connected with the second main shaft, and therefore with the second planetary gear and the output shaft, wherein the input shaft is connected with a first planetary wheel carrier, arranged in the first planetary gear, and wherein the second main shaft is connected with a planetary wheel carrier, arranged in the second planetary gear, said method comprising the steps:
a) connecting an output shaft of the combustion engine with the input shaft of the gearbox, via a coupling device, arranged between the output shaft and the input shaft; and b) controlling the first and the second electrical machine in such a way that the combustion engine is started. |
