The invention relates to a method for moving off of a vehicle with a hybrid drive line (3), comprising a combustion engine (4); a gearbox (2) with an input shaft (8) and an output shaft (20), which combustion engine is connected to the input shaft (8); a first planetary gear (10), which is connected to the input shaft (8) and a first main shaft (34); a second planetary gear (12), which is connected to the first planetary gear (10) and a second main shaft (36); a first electrical machine (14), which is connected to the first planetary gear (10); a second electrical machine (16), which is connected to the second planetary gear (12); at least one gear pair (Gl, 60, 72), connected with the first main shaft (34), and therefore with the first planetary gear (10) and the output shaft (20); and at least one gear pair (G2, 66, 78), connected with the second main shaft (36), and therefore with the second planetary gear (12) and the output shaft (20), wherein the combustion engine (4), via the input shaft (8), is connected with a first planetary wheel carrier (50) arranged in the first planetary gear (10), and wherein the second main shaft (36) is connected with a planetary wheel carrier (51), arranged in the second planetary gear (12). The method comprises the steps: a) ensuring that the rotatable components (26, 50) of the first planetary gear (10) are disconnected from each other, and ensuring that the rotatable components (32, 51) of the second planetary gear (12) are disconnected from each other, b) ensuring that gears are engaged, corresponding to the at least one gear pair (Gl, 60, 72), which is connected with the first planetary gear (10), and the least one gear pair (G2, 66, 78), which is connected with the second planetary gear (12) and c) activating the first electrical machine (14) and the second electrical machine (16), in such a way that a torque is generated in the output shaft (20). The invention also relates to a vehicle (1), which is moved off according to the method according to the invention. The invention also relates to a computer program (P) to move off a vehicle with a hybrid powertrain (3), and a computer program product comprising program code for an electronic control device (48) or another computer (53) to implement the method according to the invention. |
