PROBLEM TO BE SOLVED: To provide a driving force distribution control device for a vehicle capable of realizing the driving force distribution control having excellent consistency and responsiveness while efficiently utilizing the tire grip. SOLUTION: In a front drive vehicle, a driving force distribution ratio setting unit 50 operates the driving force distribution ratio b to wheels 12fl, 12fr with the non-linear term being minimum when the front wheel cornering power Kf_a estimated to be actually generated is expressed by a linear term specific to a vehicle body, the lateral forces Ffl_y, Ffr_y, vertical forces Ffl_z, Ffr_z applied to the front wheels 12fl, 12fr which are detected by force detection sensors 14fl, 14fr, and the driving force to the wheels 12fl, 12fr. The driving force distribution ratio of the driving forces to be transferred to the right and left front wheels 12fl, 12fr is variably controlled by a front wheel final reduction gear 10.
