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 during coast-travelling in which an engine is in an idling stop 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 has collided; a second braking control portion 167 that when determining that the own vehicle has collided, performs emergency braking control by which the VSA device 18 is made to generate braking force based on an emergency braking request regardless of braking operation by a driver; and a second information acquiring portion 161 that acquires information on a state of an engine 39 mounted on the own vehicle. The second braking control portion 167, when determining that the own vehicle has collided when the engine 39 is in an idling stop state, performs control so that the braking force based on the emergency braking request is reduced to be smaller than braking force based on an emergency braking request at the time when the engine 39 is in an operated state.SELECTED DRAWING: Figure 2

    【課題】エンジンがアイドリングストップ状態にある惰力走行の際に衝突事故に遭遇した場合であっても、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、自車両に搭載されたエンジン39の状態情報を取得する第2の情報取得部161とを備える。第2の制動制御部167は、エンジン39がアイドリングストップ状態にある際に自車両の衝突有り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、エンジン39が稼働状態にある際の緊急制動要求に基づく制動力と比べて低減させる制御を行う。【選択図】図2
