To provide an automatic braking device of a vehicle provided with a front/rear type braking system, which can reduce a feeling of strangeness given to a driver to excellently suppress a vehicle from being deflected.SOLUTION: The automatic braking device is provided in a vehicle employing two braking systems of a front-rear type. The automatic braking device comprises; a front wheel adjustment valve for adjusting liquid pressure of a front wheel of a front wheel braking system connected to a front wheel cylinder and a rear wheel adjustment valve for adjusting liquid pressure of a rear wheel of a rear wheel braking system connected to a rear wheel cylinder, which execute automatic braking control by which liquid pressure of wheel cylinders are increased from liquid pressure of master cylinders on the basis of required deceleration according to a distance between an object in front of the vehicle and the vehicle; and a controller that controls the front wheel- and rear wheel-adjustment valves on the basis of the required deceleration so that liquid pressure of the front wheel and of the rear wheel is adjusted. The controller adjusts the liquid pressure so that the liquid pressure of the rear wheel is lower than the liquid pressure of the front wheel when starting the automatic braking control.SELECTED DRAWING: Figure 3

    【課題】 前後方式の制動系統を備える車両の自動制動装置において、運転者への違和感を低減し、車両偏向が良好に抑制され得るものを提供することである。【解決手段】 自動制動装置は、2つの制動系統として前後方式を採用する車両に備えられる。自動制動装置は、車両の前方の物体と車両との距離に応じた要求減速度に基づいて、ホイールシリンダ液圧をマスタシリンダ液圧から増加する自動制動制御を実行するものであって、「前輪ホイールシリンダに接続された前輪制動系統の前輪液圧を調整する前輪調圧弁」と、「後輪ホイールシリンダに接続された後輪制動系統の後輪液圧を調整する後輪調圧弁」と、「要求減速度に基づいて、前輪、後輪調圧弁を制御することによって、前輪、後輪液圧を調整するコントローラ」と、を備える。コントローラは、自動制動制御の開始時に、前輪液圧よりも後輪液圧が小さくなるよう調整する。【選択図】 図3
