摘要:
Provided is a method to control a hybrid powertrain to achieve reverse drive, comprising an internal combustion engine, a gearbox with input output shafts; a first planetary gear connected to the input shaft and a second planetary gear; first and second electrical machines respectively connected to the first and second planetary gears; 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, wherein the internal combustion engine is connected with the first planetary gear via the input shaft. The method comprises: a) ensuring the moveable component parts in the first planetary gear are connected with each other and the moveable component parts in the second planetary gear are disconnected from each other; b) ensuring the gear pair connected with the second planetary gear and the output shaft are connected, and the gear pair connected with the first planetary gear and the output shaft are disconnected; and c) controlling the second electrical machine to achieve a negative torque in the output shaft.
