To provide a vehicle driving force distribution control device which can prevent simultaneous slipping of front and rear wheels and can eliminate anxiety of an occupant of a vehicle caused by the simultaneous slipping during automatic climbing in which a vehicle climbs a slope under automatic driving.SOLUTION: A vehicle driving force distribution control device controls distribution of driving force to a front wheel WF and a rear wheel WR during automatic climbing in which a vehicle V climbs a slope under automatic driving which automatically controls traveling of the vehicle V. The driving force distribution control device determines slipping states of the front wheel WF and the rear wheel WR respectively during the automatic climbing (a step 17 in Fig.3, Fig.4), and sets a rear distribution ratio Rt in accordance with the determined slipping states of the front wheel WF and the rear wheel WR (steps 19, 23, 25). The rear distribution ratio Rt is restricted so as not to exceed a limit value Rlmt (steps 26, 27).SELECTED DRAWING: Figure 5

    【課題】車両が自動運転の下で登坂走行する自動登坂中において、前後の車輪の同時空転を防止でき、同時空転に起因する車両の乗員の不安を解消することができる車両の駆動力配分制御装置を提供する。【解決手段】本発明は、車両Vの走行を自動的に制御する自動運転の下で車両Vが登坂走行する自動登坂中に、前輪WF及び後輪WRへの駆動力の配分を制御する車両の駆動力配分制御装置である。この駆動力配分制御装置では、自動登坂中に前輪WF及び後輪WRのスリップ状態をそれぞれ判定し(図3のステップ17、図4)、判定された前輪WF及び後輪WRのスリップ状態に応じて、リア配分比Rtを設定する(ステップ19、23、25)。このリア配分比Rtは、リミット値Rlmtを超えないように制限される(ステップ26、27)。【選択図】図5
