To provide a brake force limiting-apparatus capable of suppressing the deterioration of run-through performance due to taking too much time for converging a slip and suppressing the occurrence of an excessive input into a drive-system component.SOLUTION: A brake force limiting-apparatus, for use in limiting brake force applied to a wheel, includes: slip determination means for determining a wheel that is slipping; brake force change rate calculation means for calculating a brake force change rate to be set to the wheel that has been determined to be slipping; and brake force control means for controlling brake force at the brake force change rate when braking is required. Further the brake force change rate calculation means sets a brake force change rate larger proportionately as a rotation speed of the wheel that is slipping increases or a change amount of the rotation speed of the wheel per unit time increases, and limits a brake force change rate at or lower than a given value determined by an inertial value of a power transmission system so as not to exceed a permissible value of the power transmission system.SELECTED DRAWING: Figure 1

    【課題】スリップの収束に時間がかかることによって走破性が低下することを抑制すると共に駆動系部品に過大入力が発生することを抑制可能な制動力制限装置を提供すること。【解決手段】本発明に係る制動力制限装置は、車輪に作用する制動力を制限する制動力制限装置であって、スリップ状態にある車輪を判定するスリップ判定手段と、スリップ状態にあると判定された車輪に対して設定する制動力変化率を算出する制動力変化率算出手段と、制動要求時に制動力変化率で制動力を制御する制動力制御手段と、を備え、制動力変化率算出手段は、スリップ状態にある車輪の回転速度が速い程又は車輪の単位時間あたりの回転速度の変化量が大きいほど制動力変化率を大きく設定すると共に、動力伝達系の許容値を超えないように動力伝達系の慣性値によって定まる所定値以下に制動力変化率を制限する。【選択図】図1
