PROBLEM TO BE SOLVED: To provide a driving force control device capable of suppressing a rapid change in a driving force due to the switchover of the engagement direction of a feed screw mechanism.SOLUTION: A driving force control device comprises: a belt continuously variable transmission in which a belt is wound around a pair of pulleys; a feed screw mechanism; and an elastic member applying an elastic force to a first movable sheave of one of the pulleys from the belt so as to resist a load in an axial direction received by the first movable sheave from the belt, and is configured so that, if it is estimated that a magnitude relation between the load received by the first movable sheave from the belt and the elastic force received by the first movable sheave from the elastic member is inverted (step S6 or step S12), a motor phase control or a driving force source output control is executed so as to suppress a change in a torque output from the belt continuously variable transmission (step S9). 【課題】送りねじ機構の噛み合い方向が切り替わることによる駆動力の急激な変化を抑制することができる駆動力制御装置を提供する。【解決手段】一対のプーリにベルトが巻き掛けられたベルト式無段変速機と、送りねじ機構と、一方のプーリにおける第１可動シーブがベルトから受ける軸線方向の荷重に対抗した弾性力をその第１可動シーブに作用させる弾性部材とを備えた駆動力制御装置において、第１可動シーブがベルトから受ける荷重と、その第１可動シーブが弾性部材から受ける弾性力との大小関係が反転することが推定された際に（ステップＳ６またはステップＳ１２）、ベルト式無段変速機から出力されるトルクが変化することを抑制するための、モータ位相制御または駆動力源出力制御が実行されるように構成されている（ステップＳ９）。【選択図】図１
