A driving force control system for a vehicle (Ve) comprising: a differential mechanism that distributes torque delivered from a prime mover to a right wheel and a left wheel through a plurality of rotary elements including gears; a differential motor that controls a split ratio of the torque distributed to the right wheel and the left wheel by applying differential torque (T w ) to any one of the rotary elements , so as to allow the right wheel and the left wheel to perform a differential rotation therebetween; a limited slip differential that limits the differential rotation between the right wheel and the left wheel by applying a frictional braking force to a rotary member between the differential motor and the limited slip differential thereby applying differential limit torque (T LSD ) to the rotary member ; a controller that controls the differential motor and the limited slip differential ; and a torque vectoring device in which an operating mode is switched between differential mode in which the differential torque (T w ) overwhelms the differential limit torque (T LSD ) and differential limit mode in which the differential limit torque (T LSD ) overwhelms the differential torque (T w ), characterized in that the controller is configured to: bring the torque vectoring device into a preparatory state in which the differential torque (T w ) and the differential limit torque (T LSD ) are equalized to each other when shifting the operating mode between the differential mode and the differential limit mode; and shift the operating mode of the torque vectoring device between the differential mode and the differential limit mode by gradually reducing a difference between the differential torque (T w ) and the differential limit torque (T LSD ). a differential mechanism that distributes torque delivered from a prime mover to a right wheel and a left wheel through a plurality of rotary elements including gears; a differential motor that controls a split ratio of the torque distributed to the right wheel and the left wheel by applying differential torque (T w ) to any one of the rotary elements , so as to allow the right wheel and the left wheel to perform a differential rotation therebetween; a limited slip differential that limits the differential rotation between the right wheel and the left wheel by applying a frictional braking force to a rotary member between the differential motor and the limited slip differential thereby applying differential limit torque (T LSD ) to the rotary member ; a controller that controls the differential motor and the limited slip differential ; and a torque vectoring device in which an operating mode is switched between differential mode in which the differential torque (T w ) overwhelms the differential limit torque (T LSD ) and differential limit mode in which the differential limit torque (T LSD ) overwhelms the differential torque (T w ), characterized in that the controller is configured to: bring the torque vectoring device into a preparatory state in which the differential torque (T w ) and the differential limit torque (T LSD ) are equalized to each other when shifting the operating mode between the differential mode and the differential limit mode; and shift the operating mode of the torque vectoring device between the differential mode and the differential limit mode by gradually reducing a difference between the differential torque (T w ) and the differential limit torque (T LSD ). bring the torque vectoring device into a preparatory state in which the differential torque (T w ) and the differential limit torque (T LSD ) are equalized to each other when shifting the operating mode between the differential mode and the differential limit mode; and shift the operating mode of the torque vectoring device between the differential mode and the differential limit mode by gradually reducing a difference between the differential torque (T w ) and the differential limit torque (T LSD ). <EOS>
