PROBLEM TO BE SOLVED: To provide a vehicular braking device that can perform as quickly as possible emergency braking control of an own vehicle even if the own vehicle meets with a collision accident and emergency braking function falls partially into an abnormal state.SOLUTION: A vehicular braking device 10 comprises: a VSA device 18 that generates braking force based on a braking request for braking an own vehicle; a collision determining portion 163 that determines whether or not the own vehicle collides; a second braking control portion 167 that when determining that the own vehicle collides, performs emergency braking control by which the VSA device 18 is made to generate braking force based on the emergency braking request regardless of braking operation by a driver; and an abnormality diagnosing portion 165 that performs abnormality diagnosis of an emergency braking function member involved in execution of the emergency braking control. The second braking control portion 167, when determining that the own vehicle collides and when determining that the emergency braking function member is abnormal, reduces the braking force based on the emergency braking request, by comparing the braking force based on the emergency braking request with braking force based on emergency braking request at the time when the emergency braking function member is in a normal state.SELECTED DRAWING: Figure 2

    【課題】自車両が衝突事故に遭遇し、かつ緊急制動機能が部分的に異常状態に陥った場合であっても、自車両の緊急制動制御を可及的に遂行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、自車両を制動するための制動要求に基づく制動力を発生するVSA装置18と、自車両の衝突有無を判定する衝突判定部163と、自車両の衝突有りの判定が下された場合に、運転者の制動操作に関わらず、緊急制動要求に基づく制動力をVSA装置18に発生させる緊急制動制御を行う第2の制動制御部167と、緊急制動制御の実行に関与する緊急制動機能部材の異常診断を行う異常診断部165と、を備える。第2の制動制御部167は、自車両の衝突有りの判定が下され、かつ、緊急制動機能部材が異常である旨の判定が下された場合に、緊急制動要求に基づく制動力を、緊急制動機能部材が正常状態にある際の緊急制動要求に基づく制動力と比べて減少させる。【選択図】図2
