PROBLEM TO BE SOLVED: To appropriately perform a deviation hinderance operation for appropriately hindering deviation of a vehicle from a traffic lane in which the vehicle is traveling, according to a frictional coefficient of a road surface on which the vehicle is traveling.SOLUTION: A traffic lane deviation hindering device (17) comprises: deviation hindering means (172) that applies a brake force to a wheel (121) such that a hindering yaw moment is applied to the vehicle, the hindering yaw moment being able to hinder deviation of the vehicle (1) from a traffic lane in which the vehicle is currently traveling; and control means (173) that controls the deviation hindering means such that in a case where a frictional coefficient (μ) of a road surface is smaller than a predetermined threshold (K), a first ratio (r1), which is the ratio of a brake force applied to each front wheel (121FL, 121FR) to a brake force applied to the vehicle is larger than a second ratio (R2), which is the ratio of a brake force applied to each rear wheel (121RL, 121RR) to a brake force applied to the vehicle.SELECTED DRAWING: Figure 2

    【課題】車両が走行している路面の摩擦係数に応じて、走行車線からの車両の逸脱を適切に抑制するための逸脱抑制動作を適切に行う。【解決手段】車線逸脱抑制装置(17)は、現在走行している走行車線からの車両(1)の逸脱を抑制可能な抑制ヨーモーメントが車両に付与されるように車輪(121)に制動力を付与する逸脱抑制手段(172)と、路面の摩擦係数(μ)が所定閾値(K)より小さい場合に、前輪(121FL、121FR)に付与される制動力の車両に付与される制動力に対する比率である第1比率(r1)が、後輪(121RL、121RR)に付与される制動力の車両に付与される制動力に対する比率である第2比率(r2)よりも大きくなるように、逸脱抑制手段を制御する制御手段(173)とを備える。【選択図】図2
