摘要
A method is provided to control a hybrid powertrain that comprises: 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; 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 comprises: disconnecting a first planetary wheel carrier and a first sun wheel or disconnecting a second planetary wheel carrier and a second sun wheel from each other; b) controlling the combustion engine to a predetermined engine speed; and c) controlling the first and second electrical machines so that a desired torque is achieved in the output shaft, while a requested total power consumption of the first and the second electrical machines is achieved.
