PROBLEM TO BE SOLVED: To more accurately expand an airbag according to a collision situation of a pedestrian.SOLUTION: A pedestrian protection device comprises: a right airbag device 20R; a left airbag device 20L; G sensors 30a to 30b (collision position detector); a vehicle speed sensor 32 (vehicle speed detector); a steering angle sensor 34 (steering angle detector); and an ECU 40 (controller) that controls the activation of each airbag. The airbags 22R and 22L have tip parts 26 which are vertically overlapped with each other respectively at the center of a vehicle 1 during expansion. The ECU 40 executes the following: to estimate a moving direction of a pedestrian who collides with the vehicle 1; based on the estimation result, to determine an airbag device to be activated and its activation timing between the airbag devices 20R and 20L; and based on the determination result, to control the activation of each of the airbag devices 20R and 20L.SELECTED DRAWING: Figure 7 【課題】歩行者の衝突状況に応じて、より的確にエアバッグを展開させる。【解決手段】歩行者保護装置は、右エアバッグ装置２０Ｒと、左エアバッグ装置２０Ｌと、Ｇセンサ３０ａ〜３０ｂ（衝突位置検知装置）と、車速センサ３２（車速検知装置）と、操舵角センサ３４（操舵角検知装置）と、各エアバッグの作動を制御するＥＣＵ４０（制御装置）とを備える。各エアバッグ２２Ｒ、２２Ｌは、それぞれ、展開時に車両１の中央部で互いに上下に重なり合う先端部２６を有する。ＥＣＵ４０は、車両１に衝突した歩行者の移動方向を推測し、その推測結果に基づき、前記エアバッグ装置２０Ｒ、２０Ｌのうち、作動対象とするエアバッグ装置とその作動タイミングを決定し、その決定結果に基づき各エアバッグ装置２０Ｒ、２０Ｌの作動を制御する。【選択図】図７
