PROBLEM TO BE SOLVED: To provide an anti-skid control device which can properly calculate the vehicle body speed in the vehicle of the four-wheel driving and suitably execute anti-skid control.SOLUTION: An anti-skid control device executes anti-skid control by selectively switching between the reduction mode of reducing braking torque and the increase mode of increasing the braking torque on the basis of the comparison result between the four wheel speeds and the vehicle body speed. A controller of the anti-skid control device calculates the wheel acceleration on the basis of the wheel speed, and determines the residual state when the state which includes a control mode condition of selecting the reduction mode in each wheel and a wheel acceleration condition in which each wheel acceleration is within a range of a prescribed value and where the control mode condition and the wheel acceleration condition are simultaneously satisfied is continued over the prescribed time. When the residual state is not determined, the vehicle body speed is calculated on the basis of the maximum value of each wheel speed. When the residual state is determined, the vehicle body speed is calculated on the basis of the minimum value of each wheel speed.SELECTED DRAWING: Figure 3

    【課題】 4輪駆動の車両において、車体速度が適切に演算され、アンチスキッド制御が好適に実行され得るものを提供する。【解決手段】 4つの車輪速度と車体速度との比較結果に基づいて制動トルクを減少する減少モードと制動トルクを増加する増加モードとを選択的に切り替えてアンチスキッド制御を実行する。アンチスキッド制御装置のコントローラは、車輪速度に基づいて車輪加速度を演算し、各車輪で減少モードを選択する制御モード条件と、各車輪加速度が所定値の範囲内である車輪加速度条件と、を含んで構成され、制御モード条件と車輪加速度条件とが同時に満足される状態が所定時間に亘って継続される場合に残留状態であることを判定する。そして、残留状態を判定しない場合には、各車輪速度のうちの最大値に基づいて車体速度を演算し、残留状態を判定する場合には、各車輪速度のうちの最小値に基づいて車体速度を演算する。【選択図】 図3
