PROBLEM TO BE SOLVED: To provide a driving torque distribution control device for a four-wheel drive car that can properly control driving torque to be distributed to rear wheels so that the total of loss energy in turning is minimum.SOLUTION: A controller 20 which controls driving torque to be distributed to front wheels 9 and rear wheels 10 includes: an acquisition part 21 which acquires lateral acceleration, engine torque, and a turning radius during turning of a vehicle 1; a rear-wheel driving torque distribution ratio determination part 22 which determines a rear-wheel driving torque distribution ratio indicating the ratio of driving torque to be transmitted to the rear wheels 10 to driving torque corresponding to the engine torque based upon the lateral acceleration, engine torque, and turning radius that the acquisition part 21 acquires; and a driving torque distribution control part 23 which controls the driving torque to be distributed to the rear wheels 10 according to the rear-wheel driving torque distribution ratio that the rear-wheel driving torque distribution ratio determination part 22 determines.SELECTED DRAWING: Figure 6

    【課題】旋回中のロスエネルギーの総和が最少になるように、後輪に配分する駆動トルクを適切に制御することができる四輪駆動車の駆動トルク配分制御装置を提供する。【解決手段】前輪9と後輪10とに配分する駆動トルクを制御するコントローラ20は、車両1の旋回中に横加速度、エンジントルク及び旋回半径を取得する取得部21と、取得部21が取得した横加速度、エンジントルク及び旋回半径に基づいて、エンジントルクに対応する駆動トルクのうち後輪10に伝達する駆動トルクの比率を示す、後輪駆動トルク配分比を決定する後輪駆動トルク配分比決定部22と、後輪駆動トルク配分比決定部22が決定した後輪駆動トルク配分比に従って、後輪10に配分する駆動トルクを制御する駆動トルク配分制御部23と、を有する。【選択図】図6
