To provide a four-wheel-drive vehicle in which a deterioration in lateral force of a rear wheel is prevented, securing vehicular travel stability, even if ABS control is executed when EBD control is performed.SOLUTION: A four-wheel-drive vehicle 10 includes: a differential limit device 34 capable of changing a degree of limiting differential between a front-wheel rotation shaft 32 and a rear-wheel rotation shaft 33; and a control apparatus 40 capable of changing brake force of a front wheel and that of a rear wheel so that a distribution ratio of brake force between the front and rear wheels is at a constant value and setting brake force of each wheel independently. In the vehicle, a brake control part 120 causes the control apparatus 40 to stop EBD control in the case of ABS control being started when EBD control is performed; and a differential limit control part 110 changes a degree of limiting differential to a third degree that is larger than a first degree, and equal to or lower than a second degree in the case of ABS control being started when the EBD control is performed.SELECTED DRAWING: Figure 1

    【課題】四輪駆動車両であって、EBD制御が実行されているときに、ABS制御が実行されても、後輪の横力の低下を防止し、車両の走行安定性を確保する。【解決手段】前輪用回転軸32と後輪用回転軸33の差動の制限度合いを変更可能な差動制限装置34と、前輪の制動力と後輪の制動力との配分比が一定値になるように前輪の制動力と後輪の制動力を変更するとともに各車輪の制動力を互いに独立に設定可能に構成された制動装置40と、を有する四輪駆動車両10において、制動制御部120は、EBD制御が行われている場合にABS制御が開始されたとき、制動装置40にEBD制御を中止させるように構成され、差動制限制御部110は、EBD制御が行われている場合にABS制御が開始されたとき、差動の制限度合いを第1の度合いより大きく且つ第2の度合い以下の第3の度合いに変更する。【選択図】図1
