Claim Text:
1. A device for torque vectoring in a wheeled vehicle, comprising: a differential mechanism comprising a differential arranged on an axle having a first drive shaft and a second drive shaft, an electrical power source connected to an electrical motor, said electrical motor being connectable to said axle for torque vectoring between said first drive shaft and said second drive shaft, wherein said electrical motor is connected to said first drive shaft and said second drive shaft by means of a planetary gear set, and control means connected to said power source and configured to receive a plurality of variables representing the current vehicle state and to determine drive currents being dependent on said variables, wherein said drive currents are supplied to said electrical motor from said power source for introducing a torque increase to either one of said first or second drive shafts and a corresponding torque decrease to the other one of said first or second drive shafts; wherein said electrical power source comprises an accumulator, and wherein said control means comprises: wherein said controller is controlling an electrical motor control functionality by executing a plurality of control programs, wherein at least some of the control programs are executed in parallel to each other, each control program being designed to control a respective aspect of driving dynamics of the vehicle by calculating torque requests to said electrical motor, as represented by said one or more control signals to the power electronics unit, based on said plurality of variables representing the current vehicle state.
