A device for torque vectoring in a wheeled vehicle is provided. The device comprises a differential mechanism (130, 220a, 220b, 320, 406) arranged on an axle (110, 210, 310, 402) having a first drive shaft (214, 314, 402 L ) and a second drive shaft (216, 316, 402 R ), an electrical power source (424) connected to an electrical motor (140, 230, 330, 410), said electrical motor (140, 230, 330, 410) being connectable to said axle (110, 210, 310, 402) for torque vectoring between said first drive shaft (214, 314, 402 L ) and said second drive shaft (216, 316, 402 R ), wherein said electrical motor (330) is connected to said first drive shaft (314) and said second drive shaft (316) by means of a planetary gear set (340), and control means (150, 420, 430, 440) connected to said power source (424) and configured to receive a plurality of variables (442, 444) representing the current vehicle state and to determine drive currents (412) being dependent on said variables (442, 444), wherein said drive currents (412) are supplied to said electrical motor (140, 230, 330, 410) from said power source (424) for introducing a torque increase to either one of said first or second drive shafts (214, 216, 314, 316, 402 L , 402 R ) and a corresponding torque decrease to the other one of said first or second drive shafts (214, 216, 314, 316, 402 L , 402 R ). |
