    摘要： A drive system for a vehicle includes two electrical machines arranged between a combustion engine and an input shaft to a gearbox. The first electrical machine rotor is connected with a planetary gear component, and the input shaft of the gearbox is connected with another planetary gear component. The second electrical machine rotor is connected via a transmission with the output shaft of the combustion engine, which is connected with another planetary gear component. planetary gear's components may be locked together to rotate at the same rotational speed, and released wherein the components rotate at different rotational speeds. Further, the output shaft of the combustion engine may either be locked in position with or released from the additional planetary gear component.

    摘要： A method for moving off of a hybrid vehicle with a propulsion system (1) including a planetary gear with three components: a sun gear (10), a ring gear (11) and a planet wheel carrier (12). The output shaft (2a) of a combustion engine (2) is connected to a first component of an input shaft (3a) of a gearbox (3) is connected to a second component and the rotor (9b) of an electric machine (9) is connected to a third component. The propulsion system has a locking device transferable between a locking position and a releasing position respectively, in which the components rotate as a unit and with different rotation speeds respectively. The method starts from an initial state with the combustion engine idle, the locking device in the releasing position and a gear, appropriate for moving off, engaged in the gearbox. The electric machine is controlled to apply a positive torque on the third component of the planetary gear, and the rotation speed of the combustion engine is controlled towards a constant rotation speed. A reaction torque is created and gives rise to a demanded driving torque, whereby the vehicle moves off.
