To improve the accelerating performance and the turning performance of a vehicle.SOLUTION: In a four-wheel driving force distribution apparatus for distributing driving force to each wheel of a four-wheel drive vehicle, the distribution of driving force to a front inside wheel (2a) and the distribution of driving force to a rear inside wheel (3a) are adjusted on the basis of a ground load of the front inside wheel (2a) and a ground load of the rear inside wheel (3a) at the time of turning of the vehicle. As the ratio of the ground load of the front inside wheel (2a) to the ground load of the rear inside wheel (3a) during turning becomes smaller, the distribution of driving force to the front inside wheel (2a) is made smaller than the distribution of driving force to the rear inside wheel (3a).SELECTED DRAWING: Figure 8

    【課題】車両の加速性能および旋回性能を向上させる。【解決手段】四輪駆動車両の各車輪に駆動力を分配する四輪駆動力分配装置において、車両の旋回時に前内輪(2a)の接地荷重と後内輪(3a)の接地荷重に基づいて、前内輪(2a)への駆動力配分と後内輪(3a)への駆動力配分を調整する。旋回中の後内輪(3a)の接地荷重に対する前内輪(2a)の接地荷重の割合が小さくなるほど前内輪(2a)への駆動力配分を後内輪(3a)への駆動力配分よりも小さくする。【選択図】図8
