PROBLEM TO BE SOLVED: To provide a vehicular braking device capable of suppressing the occurrence of the sense of discomfort due to the characteristic of a differential pressure valve while suppressing influence on pedal feeling.SOLUTION: A vehicular braking device includes a storage section 61 which stores a first relation f1 which is a relation between brake operation amount when the brake operation amount is in the range less than first brake operation amount and is increasing and first differential pressure, and a second relation f2 which is a relation between brake operation amount when the brake operation amount is the range less than the first brake operation amount and is decreasing and the first differential pressure. The first relation f1 is a relation in which the first differential pressure increases as the brake operation amount increases while the second relation f2 is a relation in which the first differential pressure decreases as the brake operation amount decreases. A decrease width of the first differential pressure per unit decrease width of the brake operation amount in the second relation f2 is set to be larger than an increase width of the first differential pressure per unit increase width of the brake operation amount in the first relation f1.SELECTED DRAWING: Figure 9

    【課題】ペダルフィーリングへの影響を抑制しつつ、差圧弁の特性による違和感の発生を抑制することができる車両用制動装置を提供する。【解決手段】本発明は、ブレーキ操作量が第1ブレーキ操作量未満の範囲で且つ増大中である場合におけるブレーキ操作量と第一差圧との関係である第1関係f1、及び、ブレーキ操作量が第1ブレーキ操作量未満の範囲で且つ減少中である場合におけるブレーキ操作量と第一差圧との関係である第2関係f2が記憶されている記憶部61を備え、第1関係f1は、ブレーキ操作量が増大するほど第一差圧が増大する関係であり、第2関係f2は、ブレーキ操作量が減少するほど第一差圧が減少する関係であり、第2関係f2におけるブレーキ操作量の単位減少幅当たりの第一差圧の減少幅は、第1関係f1におけるブレーキ操作量の単位増大幅当たりの第一差圧の増大幅よりも大きく設定されている。【選択図】図9
