METHOD FOR TAKEOFF OF A VEHICLE WITH A HYBRID DRIVELINE

摘要

A method is provided for moving off of a vehicle with a hybrid drive line, comprising a combustion engine; a gearbox with input shaft connected to the combustion engine and output shaft; a first planetary gear, which is connected to the input shaft, a first main shaft; a second planetary gear connected to the first planetary gear and a second main shaft; a first and second electrical machines respectively connected to the first and second planetary gears; a gear pair connected with the first main shaft; and a gear pair connected with the second main shaft. The method comprises: a) ensuring that the rotatable components of the first and second planetary gears are respectively disconnected from each other, b) ensuring that the corresponding gear pairs are engaged, and c) activating the first and second electrical machines so that a torque is generated in the output shaft.

1. A method for moving off of a vehicle with a hybrid powertrain, comprising a combustion engine; a gearbox with an input shaft and an output shaft, which combustion engine is connected to the input shaft; a first planetary gear, which is connected to the input shaft and a first main shaft; a second planetary gear, which is connected to the first planetary gear and a second main shaft a first electrical machine, which is connected to the first planetary gear; a second electrical machine, which is 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 combustion engine. via 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, wherein said method comprises:
a) ensuring that the rotatable components of the first planetary gear are disconnected from each other, and ensuring that the rotatable components of the second planetary gear are disconnected from each other; b) ensuring gears are engaged, corresponding to the at least one gear pair, which is connected with the first planetary gear, and the at least one gear pair, which is connected with the second planetary gear; and c) activating the first electrical machine and the second electrical machine, in such a way that a torque is generated in the output shaft.
