PROBLEM TO BE SOLVED: To prevent intervention timing of ABS control from being retarded during control of restricting an increase in a brake fluid pressure at the time of abrupt braking, and inhibit ABS control from being unstable.SOLUTION: A vehicular control unit (control unit 20) includes slip length estimation means (slip length calculation means 102) that estimates a slip length SL, anti-lock brake control means 110 that performs ABS control, abrupt braking discrimination means 120 that discriminates presence or absence of abrupt braking before ABS control is intervened, braking force restriction means (wheel cylinder pressure restriction means 130) that sustains a braking force when abrupt braking is present, or increases the braking force at a gradient smaller than the gradient of the braking force observed before the presence or absence of abrupt braking is discriminated, and threshold setting means 111 that sets an intervention threshold of ABS control to a first threshold when abrupt braking is absent, and sets the intervention threshold to a second threshold, which makes it easier to intervene ABS control than the first threshold does, when the abrupt braking is present.SELECTED DRAWING: Figure 3

    【課題】急制動時にブレーキ液圧の増加を制限する制御において、ABS制御の介入タイミングが遅れてしまうのを抑えるとともに、ABS制御が不安定になるのを抑制することを目的とする。【解決手段】車両用制御装置(制御部20)は、スリップ量SLを推定するスリップ量推定手段(スリップ量算出手段102)と、ABS制御を実行するアンチロックブレーキ制御手段110と、ABS制御が介入される前において急制動の有無を判定する急制動判定手段120と、急制動があった場合に、ブレーキ力を保持、または、急制動の判定前のブレーキ力の勾配よりも小さな勾配でブレーキ力を増加させるブレーキ力制限手段(ホイールシリンダ圧制限手段130)と、急制動がなかった場合に、ABS制御の介入閾値を第1閾値に設定し、急制動があった場合に、介入閾値を、第1閾値よりもABS制御に介入しやすい値である第2閾値に設定する閾値設定手段111を備える。【選択図】図3
