A method for obtaining gear shifting of a vehicle having a planetary gearing in the drive train, a combustion engine (2) with an output shaft (35) connected to a rotor of a second electric machine (30) and to a first component (10) of the planetary gearing, a first electric machine (9) with a rotor connected to a third component (11) of the planetary gearing and an input shaft (3a) of a gearbox (3) connected to a second component (12) of the planetary gearing. The gear shifting procedure is started with the components of the planetary gearing interlocked by a locking means (15), in which they are released during the gear shifting and interlocked again after the gear shifting has been carried out. |
