To provide a vehicle behavior stabilization device capable of improving a driver's feeling of operating a vehicle and reliably stabilizing a vehicle behavior.SOLUTION: A vehicle behavior stabilization device 30 includes: a vehicle body β calculation unit 41 for calculating a vehicle body slide angle β based on a front wheel steering angle δf, a yaw rate γ, and a vehicle speed V; a rear wheel slide angle calculation unit 42 for calculating a rear wheel slide angle βr based on the vehicle body slide angle β, the yaw rate γ, and the vehicle speed V; yaw moment imparting means (31, 32) for imparting a yaw moment M to a vehicle 1; a vehicle behavior stabilization control unit 33 for selectively controlling the yaw moment imparting means in a direction to stabilize a vehicle behavior by comparing the rear wheel slide angle βr with predetermined start threshold βrths and end threshold βrthe; and a start threshold correction unit 46 and an end threshold correction unit 48 for correcting the start threshold βrths and the end threshold βrthe based on a rate of change βdot of the vehicle body slide angle β.SELECTED DRAWING: Figure 2

    【課題】ドライバの車両を操る感覚を向上でき、且つ車両挙動を確実に安定化させることができる車両挙動安定化装置を提供する。【解決手段】車両挙動安定化装置30は、前輪舵角δf、ヨーレートγ及び車速Vに基づいて車体すべり角βを演算する車体β算出部41と、車体すべり角β、ヨーレートγ及び車速Vに基づいて後輪すべり角βrを演算する後輪すべり角算出部42と、車両1にヨーモーメントMを付与するヨーモーメント付与手段(31、32)と、後輪すべり角βrを所定の開始閾値βrths及び終了閾値βrtheと比較することにより、車両挙動を安定化させる方向にヨーモーメント付与手段を選択的に制御する車両挙動安定化制御部33と、開始閾値βrths及び終了閾値βrtheを車体すべり角βの変化率βdotに基づいて補正する開始閾値補正部46及び終了閾値補正部48とを有する。【選択図】図2
