To provide a driving force distribution control system of a vehicle which can suppress the slip of rear wheels on which the ground load is reduced in towing and accelerating in a four-wheel drive vehicle.SOLUTION: A driving force distribution control system of a vehicle comprises: a driving force distribution device which distributes the driving force of front and rear wheels; and a driving force distribution control device which controls the driving force distribution amount of the front and rear wheels. The driving force distribution control device comprises: towing determination means which determines whether or not a four-wheel drive vehicle is towing a towing object vehicle; and request acceleration detection means which detects the request acceleration of a driver. The driving force distribution control device is configured to control the driving force distribution device such that the driving force distribution amount to the rear wheels of the four-wheel drive vehicle becomes smaller as the request acceleration of the driver is greater when it is determined that the four-wheel drive vehicle is towing the towing object vehicle and the request acceleration of the driver is detected.SELECTED DRAWING: Figure 1

    【課題】四輪駆動車において、牽引時かつ加速時に、接地荷重が減少する後輪のスリップを抑制することができる車両の駆動力配分制御システムを提供する。【解決手段】本発明による車両の駆動力配分制御システムは、前後輪の駆動力を配分する駆動力配分装置と、前後輪の駆動力配分量を制御する駆動力配分制御装置と、を備え、駆動力配分制御装置は、四輪駆動車が上記被牽引車を牽引しているか否かを判定する牽引判定手段と、ドライバの要求加速度を検出する要求加速度検出手段と、を備え、駆動力配分制御装置は、四輪駆動車が被牽引車を牽引していると判定され、かつ、ドライバの要求加速度が検出されているとき、ドライバの要求加速度が大きいほど四輪駆動車の後輪への駆動力配分量が小さくなるよう駆動力配分装置を制御するように構成されている。【選択図】図1
