Abstract
A device for torque vectoring in a wheeled vehicle is presented. The device includes a differential mechanism arranged on an axle having a first drive shaft and a second drive shaft, an electrical power source connected to an electrical motor, the electrical motor being connectable to the axle for torque vectoring between the first drive shaft and the second drive shaft, and control means connected to the power source and configured to receive a plurality of variables representing the current vehicle state and to determine drive currents being dependent on the variables, wherein the drive currents are supplied to the electrical motor from the power source for introducing a torque increase to either one of the first or second drive shafts and a corresponding torque decrease to the other one of the first or second drive shafts.
