A method is provided to start a combustion engine in a hybrid powertrain, comprising a gearbox with input shaft and output shaft; which combustion engine is connected to the input shaft; a first planetary gear connected to the input shaft; a second planetary gear connected to the first planetary gear; first and second electrical machines, respectively connected to the first and second planetary gears; at least one gear pair, connected with the first planetary gear and the output shaft; and at least one gear pair, connected with the second planetary gear and the output shaft. The method comprises connecting the rotatable components of the second planetary gear with each other by connecting, via a second coupling device, a second sun wheel arranged in the second planetary gear and a second planetary wheel carrier with each other, and activating the first and second electrical machines to start the combustion engine.
