PROBLEM TO BE SOLVED: To secure the traveling stability of a vehicle even if a friction coefficient related to a brake friction material is changed.SOLUTION: A vehicle stabilizer 1 has a VSA device 6 which performs ABS control at braking, and makes a brake device 30 generate a brake force for suppressing the rotation of a wheel, and an AS device 4 which operates so as to eliminate the moment of the vehicle. A vehicle control device 50 estimates a friction coefficient (pad μ value) related to a brake friction material of the vehicle, calculates brake forces of left and right wheels by using the estimated friction coefficient, also calculates a yaw moment which is generated at the wheel on the basis of a brake force difference between a brake force for suppressing the rotation of the left-side wheel 3 and a brake force for suppressing the rotation of the right-side wheel 3, and sets a control amount of the AS device 4 on the basis of the calculated yaw moment.SELECTED DRAWING: Figure 1

    【課題】制動用摩擦材に係る摩擦係数が変化した場合であっても、車両の走行安定性を確保する。【解決手段】車両安定化装置1は、制動時にABS制御を実行して車輪の回転を抑える制動力を制動装置30に発生させるVSA装置6と、車両のヨーモーメントを解消するように作動するAS装置4とを有する。車両制御装置50は、車輪の制動用摩擦材に係る摩擦係数(パッドμ値)を推定し、推定した摩擦係数を用いて左右の車輪の制動力を算出し、さらに、左側車輪3の回転を抑える制動力と右側車輪3の回転を抑える制動力との制動力差に基づいて車両に生じるヨーモーメントを算出し、算出したヨーモーメントに基づいてAS装置4の制御量を設定する。【選択図】図1
