To provide a torque distribution control device of a four-wheel drive vehicle capable of improving traveling performance by enabling optimum front/rear and right/left torque distribution control to be performed in such a case, and thus effectively preventing vehicle's behavior from becoming unstable.SOLUTION: If front/rear distribution driving torque (TM, TS) that a front/rear torque distribution device distributes to sub driving wheels exceeds its command value as command values (TR,TL) of left/right distribution driving torque that a left/right torque distribution device distributes to a left sub driving wheel and a right sub driving wheel have a difference (left/right difference), one of left/right difference preferential control to let the left/right distribution driving torque follow up its command values preferentially and left/right difference preferential control to let the front/rear distribution driving torque follow up its command value preferentially is selected and performed according to a traveling state of the vehicle.SELECTED DRAWING: Figure 6
【課題】前後及び左右の駆動トルク配分制御を行う際に、より最適なトルク配分制御を行うことができるようにすることで、車両の挙動が不安定になることを効果的に防止して走行性能の向上を図ることができる車両のトルク配分制御装置を提供すること。【解決手段】左右トルク配分装置で左副駆動輪と右副駆動輪それぞれに配分する左右配分駆動トルクの指令値（ＴＲ，ＴＬ）に差（左右差）が生じることで、前後トルク配分装置で副駆動輪に配分する前後配分駆動トルク（ＴＭ，ＴＳ）がその指令値を上回る場合、車両の走行状態に応じて、左右配分駆動トルクをその指令値に追従させることを優先する左右差優先制御と、前後配分駆動トルクをその指令値に追従させることを優先する左右和優先制御とのいずれかを選択して行う。【選択図】図６
