PROBLEM TO BE SOLVED: To provide a four-wheel drive vehicle equipped with a damper device, which suppresses generation of abnormal sound in torque transmitting means without changing damper characteristics while suppressing deterioration in fuel economy.SOLUTION: A control device 34 is provided in a four-wheel drive vehicle 10 that has: an engine 14; torque transmitting means 50 that transmits output torque Tof the engine 14 to front wheels 12F as main driving wheels and rear wheels 12R as auxiliary driving wheels; a coupling 28 for adjusting torque Tto be distributed to the rear wheels 12R; and abnormal sound reducing means that makes the coupling 28 to adjust the distribution of torque to the rear wheels 12R so as to suppress generation of abnormal sound when operating the engine in an abnormal sound generation area where the torque transmitting means 50 becomes an abnormal sound generation state. The four-wheel drive vehicle 10 has a damper device 23 in a torque transmission path to the rear wheels 12R, and the abnormal sound reducing means adjusts the distribution of torque to the rear wheels 12R corresponding to the abnormal sound generation area which varies in response to change in damper characteristics of the damper device 23.SELECTED DRAWING: Figure 5

    【課題】ダンパ装置を備えた四輪駆動車において、燃費の悪化を抑制しながらダンパ特性の変化によらずトルク伝達手段における異音発生を抑制する。【解決手段】エンジン14と、エンジン14の出力トルクTを主駆動輪である前輪12Fと補助駆動輪である後輪12Rとに伝達するトルク伝達手段50と、後輪12Rに対する配分トルクTRを調整するカップリング28と、トルク伝達手段50が異音発生状態となる異音発生領域でのエンジン作動時に、異音の発生を抑制するようにカップリング28により後輪12Rに対するトルク配分を調整する異音低減手段とを有する四輪駆動車10の制御装置34であって、四輪駆動車10は後輪12Rに対するトルク伝達経路にダンパ装置23を有しており、異音低減手段は、ダンパ装置23のダンパ特性の変化に応じて変化する異音発生領域に対応して後輪12Rに対するトルク配分を調整する。【選択図】図5
