A driving force control system for a vehicle is provided to control a torque vectoring device is provided. A controller is configured to bring the torque vectoring device into a preparatory state in which the differential torque and the differential limit torque are equalized to each other when shifting the operating mode between the differential mode and the differential limit mode, and to shift the operating mode of the torque vectoring device by gradually reducing a difference between the differential torque and the differential limit torque.
