PROBLEM TO BE SOLVED: To provide a vehicle torque distribution control device capable of improving the accuracy of the drive torque allocated between right/left rear wheels (auxiliary drive wheels) by avoiding becoming too small command value (command torque) less than the limit while achieving the optimal torque distribution control.SOLUTION: A vehicle torque distribution control device comprises: a left clutch provided on the route transmitting the drive torque to a left rear wheel (WRL); and a right clutch provided on the route transmitting the drive torque to a right rear wheel (WRR). When each of the command value (LTq) of the drive torque allocated to the left rear wheel by the left clutch and the command value (RTq) of the drive torque allocated to the right rear wheel by the right clutch is lower than the respective predetermined lower limits (LTq1 and RTq1), control means perform control to set the command value of the drive torque to a predetermined lower limit value.SELECTED DRAWING: Figure 5
【課題】最適なトルク配分制御を実現しながらも、左右の後輪（副駆動輪）に配分するトルクの指令値（指令トルク）が限度を越える小さな値となることを回避することで、左右の後輪に配分する駆動トルクの精度を向上させることができる車両のトルク配分制御装置を提供する。【解決手段】左後輪（ＷＲＬ）に駆動トルクを伝達する経路に設けた左のクラッチと、右後輪（ＷＲＲ）に駆動トルクを伝達する経路に設けた右のクラッチとを備え、制御手段は、左のクラッチで左後輪に配分する駆動トルクの指令値（ＬＴｑ）と、右のクラッチで右後輪に配分する駆動トルクの指令値（ＲＴｑ）とがそれぞれ所定の下限値（ＬＴｑ１，ＲＴｑ１）を下回る場合、当該駆動トルクの指令値を所定の下限値とする制御を行う。【選択図】図５
