PROBLEM TO BE SOLVED: To early estimate the upstream fluid pressure of an inlet valve during ABS control.SOLUTION: A control unit 100 is equipped with ant-lock brake controlling means 150 which executes ABS control repeating a control cycle including at least decompression control and boosting control; and upstream fluid pressure estimating means 140 for estimating the upstream fluid pressure of an inlet valve 13. The anti-lock brake control means 150 executes intermittently boosting control which repeats holding and boosting by fully closing and opening the inlet valve 13, in at least the first boosting control. The upstream fluid pressure estimating means 140 estimates the upstream fluid pressure when starting the decompression of this time, on the basis of the upstream fluid pressure when starting the decompression of the last time, and decompression time and boosting time in the control cycle.SELECTED DRAWING: Figure 3
【課題】ABS制御中における入口弁の上流液圧を早期に推定することを目的とする。【解決手段】制御部100は、少なくとも減圧制御および増圧制御を含む制御サイクルを繰り返し行うABS制御を実行するアンチロックブレーキ制御手段150と、入口弁13の上流液圧を推定する上流液圧推定手段140を備える。アンチロックブレーキ制御手段150は、少なくとも最初の増圧制御において、入口弁13を全閉・全開させて保持と増圧を繰り返し行う断続増圧制御を実行する。上流液圧推定手段140は、前回の減圧開始時の上流液圧と、制御サイクルにおける減圧時間と増圧時間とに基づいて、今回の減圧開始時の上流液圧を推定する。【選択図】図3
