The present invention concerns a drive system and a method of driving a vehicle (1). The drive system comprises a combustion engine (2) with an output shaft (2a), a gear box (3) with an input shaft (3a) and a planetary gear which comprises a sun wheel (10), a ring wheel (11) and a planet wheel holder ( 12). The output shaft (2a) of the combustion engine is connected to a first of said components (10) and the input shaft (3a) of the gear box is connected to a second of said components (12). The drive system comprises a brake device (21, 22) which is adapted to supply a braking moment to a third of the components (11, 11a) of the planetary gear and a control unit ( 18) which is adapted to activate the brake device (21, 22) such that it brakes the third component (11) of the planetary gear with a braking moment during at least a starting process of the vehicle (1). |
