PROBLEM TO BE SOLVED: To provide an anti-lock brake control device capable of quickly and correctly determining that wheels are in slip tendency and thereby capable of shortening a braking distance of a vehicle.SOLUTION: There are provided: wheel motion estimation means 13 for estimating at least one of an angle, an angular speed, and an angular acceleration of a wheel 2; and slip estimation means 14 for estimating a slip state of the wheel by using the estimation result. Also, there is provided an anti-lock control device 15 for giving a brake device 1 a command to reduce a braking force according to the estimated slip state of the wheel. The slip estimation means 14 includes delay compensators 17a, 17b such as one or a plurality of filters for performing delay compensations for the estimation result of the wheel motion estimation means 13. The anti-lock control device 15 gives the command to reduce the braking force according to prescribed determination results including a comparison of a plurality of estimation results outputted from the slip estimation means 14.SELECTED DRAWING: Figure 1

    【課題】 車輪がスリップ傾向にあることを迅速かつ正確に判断できて、車両の制動距離を短縮できるアンチロックブレーキ制御装置を提供する。【解決手段】 車輪2の角度、角速度、および角加速度の何れか1つ以上を推定する車輪運動推定手段13と、その推定結果を用いて車輪の滑り状態を推定する滑り推定手段14を備える。その推定された車輪の滑り状態に応じてブレーキ装置1に制動力を低下させる指令を与えるアンチロック制御手段15を備える。前記滑り推定手段14は、車輪運動推定手段13の推定結果に対する遅れ補償を行う一つまたは複数のフィルタ等の遅れ補償器17a,17bを有する。アンチロック制御手段15は、滑り推定手段14から出力された複数の推定結果の比較を含む所定の判断の結果によって前記制動力を低下させる指令を与える。【選択図】 図1
