摘要

A method is provided for controlling a hybrid powertrain, comprising a combustion engine; a gearbox with input and output shafts; a first planetary gear connected to the input; a second planetary gear connected to the first planetary gear; first and second electrical machines capable of operating each other and respectively connected to the first planetary gear and to the second planetary gear; one gear pair connected with the first planetary gear and the output shaft; and one gear pair connected with the second planetary gear and the output shaft. The method comprising, while the combustion engine is operating: ensuring that gears are engaged in the one gear pair connected with the first planetary gear and the one gear pair connected with the second planetary gear, and activating the first and second electrical machines so that total emitted electrical power is zero and a torque is generated in the output shaft.
