PROBLEM TO BE SOLVED: To provide a passenger protection apparatus capable of deploying an airbag when a secondary collision fatal to a passenger may occur even if a collision detection sensor fails due to a slight primary collision to the extent that the primary collision does not satisfy an airbag actuation condition in a situation where a vehicle collides with an obstacle a plurality of times.SOLUTION: The passenger protection apparatus of the present invention deploys the airbag if the magnitude of a first collision detected by the collision detection sensor does not satisfy an airbag actuation condition, elapsed time since start time of a failure state corresponding to time when a failure signal transmitted when the collision detection sensor fails due to the first collision is received until present time is within predetermined time, and the magnitude of a second collision that is estimated on the basis of an output value from the collision detection sensor after output of the failure signal and that occurs after the first collision satisfies the airbag actuation condition.SELECTED DRAWING: Figure 2

    【課題】車両が複数回にわたり障害物と衝突する状況において、エアバッグの作動条件を満たさない程度の軽度な一次衝突により衝突検知センサに故障が生じた場合であっても、乗員にとって致命的な二次衝突が発生するときにはエアバッグを展開可能な乗員保護装置を提供することを課題とする。【解決手段】本発明の乗員保護装置は、衝突検知センサが検知した第1の衝突の大きさがエアバッグの作動条件を満たしていない場合であって、第1の衝突により衝突検知センサに対して故障が生じた場合に送信される故障信号を受信した時点に対応する故障状態の開始時刻から現在時刻までの経過時間が所定時間以内であり、且つ、故障信号の出力後に衝突検知センサの出力値に基づいて推定される第1の衝突後に発生する第2の衝突の大きさがエアバッグの作動条件を満たす場合には、エアバッグを展開させる。【選択図】図2
