To provide a vehicular drive force control apparatus capable of transmitting torque to each drive wheel in accordance with required drive force even in a case where the radius of the drive wheel is changed.SOLUTION: A drive-force control apparatus includes a first drive-force source connected to a predetermined drive wheel and a second drive-force source connected to another drive wheel. A torque instruction determination part 15 calculates target torque of the first and second drive-force sources in accordance with a distribution ratio of drive force in the case where radius of the predetermined drive wheel and that of the other drive wheel are set to be pre-determined values. A tire radius ratio detection part 17 calculates a ratio between the radius of the predetermined drive wheel and that of the other drive wheel. An instruction correction part 16 corrects the target torque of the first and second drive-force sources on the basis of the ratio between the radius of the predetermined drive wheel and that of the other drive wheel.SELECTED DRAWING: Figure 3
【課題】駆動輪の半径が変化した場合であっても、要求駆動力に応じたトルクを各駆動輪に伝達できる車両の駆動力制御装置を提供する。【解決手段】所定の駆動輪に連結された第1駆動力源と、他の駆動輪に連結された第2駆動力源とを備え、トルク指令決定部15により、所定の駆動輪と他の駆動輪との半径を予め定められた所定値とした場合における駆動力の配分比に応じた第1駆動力源と第2駆動力源との目標トルクを求め、タイヤ径比検出部17により、所定の駆動輪の半径と他の駆動輪の半径との比を求め、指令補正部16により、所定の駆動輪の半径と他の駆動輪の半径との比に基づいて、第1駆動力源と第2駆動力源との目標トルクを補正する。【選択図】図3
