Method for controlling hybrid powertrain, hybrid powertrain, and vehicle including such hybrid powertrain

摘要

The present invention relates to a method for controlling a hybrid powertrain (2) comprising a combustion engine (3), an electric machine (4), a gearbox (6) having an input shaft (10) and an output shaft (18), the combustion engine (3) and the electric machine (4) are connected to the input shaft (10). The method comprises: a) releasing the combustion engine 3 from the input shaft 10 with a coupling device 12, b) the torque of the combustion engine 3 at idle speed, which is capable of operating the input shaft 10. Engaging the starting gear in the gearbox 6 higher than the gear, c) generating torque on the input shaft with the electric machine 4, d) accelerating the electric machine 4, and e) the electric machine ( 4) connecting the combustion engine 3 to the input shaft 10 with the coupling device 12 when the rotational speed substantially equal to the combustion engine 3 is reached. The invention also relates to a hybrid powertrain 2 and a vehicle 1.
