PROBLEM TO BE SOLVED: To provide a vehicular braking apparatus capable of maintaining a comfortable braking operation feeling even when a power supply device falls in to an unstable power supply state.SOLUTION: A vehicular braking apparatus 10 includes: a primary hydraulic pressure generation device 14 for generating primary hydraulic pressure of a brake fluid; a secondary hydraulic pressure generation device 16 for generating secondary hydraulic pressure of the brake fluid when driven by a brake motor 72; normal-open first and second shutoff valves 60a, 60b; a control part 215 for controlling driving of the brake motor 72 and operations of opening or closing of the first and second shutoff valves 60a, 60b; a power supply device 217; and a prediction part 213 for predicting occurrence of an event where a power supply becomes unstable. In a case where the prediction part 213 predicts occurrence of the event where the power supply becomes unstable, a control part 215 performs drive control relative to the brake motor 72 so that the secondary pressure of the brake fluid approaches the primary pressure of the brake fluid.
【課題】電源装置が不安定な給電状態に陥った際であっても、快適な制動操作フィーリングを維持可能な車両用制動装置を提供する。【解決手段】車両用制動装置10は、制動液の一次液圧を発生させる一次液圧発生装置14と、制動モータ72の駆動により制動液の二次液圧を発生させる二次液圧発生装置16と、常開型の第1及び第2遮断弁60a,60bと、制動モータ72の駆動制御、及び、第1及び第2遮断弁60a,60bに係る開放又は遮断の動作制御を行う制御部215と、電源装置217と、電源が不安定になる事態の発生を予測する予測部213と、を備える。制御部215は、予測部213により電源が不安定になる事態の発生が予測される場合に、制動液の二次液圧を、制動液の一次液圧に近づけるように制動モータ72に係る駆動制御を行う。【選択図】図2
