Provided is a driving force control apparatus (10) configured to control driving forces applied to four wheels by controlling a driving force application apparatus (in-wheel motors (16FL to 16RR) and friction braking apparatus (24)) configured to apply driving forces to front left and right wheels (12FL and 12FR) and rear left and right wheels (12RL and 12RR) independently. The driving force control apparatus (10) is configured to: calculate vehicle body speeds Vj at positions of the four wheels, vertical loads Fzj of the four wheels, and a driving force Fx required by a driver (S30 to S50); calculate, based on those values, target driving forces Fxj for the four wheels to set tire sliding vectors of the four wheels to be the same (S60); and control the driving force application apparatus such that the driving forces of the four wheels are equal to corresponding target driving forces, respectively (S70).
