Abstract
A torque vectoring system for a hub motor drive system uses a motor control unit instead of a vehicle control unit to conduct torque vectoring calculation, so that a target motor torque can be obtained more reasonably and the real-time property is improved. In addition, as it is unnecessary to conduct calculation with the vehicle control unit, torque distribution and torque change can be evaluated on a testbed of the motor control unit prior to integrating the torque vectoring system into the vehicle.
