PROBLEM TO BE SOLVED: To provide an occupant state determination device for determining a state of an occupant when a vehicle is decelerated suddenly, and properly protecting an occupant.SOLUTION: An occupant state determination device 20 comprises: a level determination part 24 for classifying a movement amount to any one of preset plural levels L1-L5; and an occupant protection control part 26 for changing actuation of an occupant protection device 30 for protecting an occupant. A signal reception part 25 receives a brake operation signal Bs and then identifies a level L corresponding to the movement amount calculated by an occupant movement amount calculation part 22. An occupant protection control part 26 changes actuation of the occupant protection device 30 according to the identified level L. According to such a configuration, the movement amount of the occupant is calculated based on acceleration Gs, the level L corresponding to the movement amount is identified, and the actuation of the occupant protection device 30 is changed according to the identified level L. Therefore, even when the vehicle V is suddenly decelerated by an automatic brake 11, the occupant can be protected properly.SELECTED DRAWING: Figure 1
【課題】車両が急減速するときの乗員の状態を判定して、乗員の保護を適切に行える乗員状態判定装置を提供することである。【解決手段】乗員状態判定装置20は、予め設定した複数のレベルL1〜L5のいずれかに移動量を区分するレベル化部24と、乗員を保護する乗員保護装置30の作動を変化させる乗員保護制御部26とを有する。信号受信部25は、ブレーキ作動信号Bsを受信すと、乗員移動量算出部22が算出した移動量に対応するレベルLを特定する。乗員保護制御部26は、特定したレベルLに応じて乗員保護装置30の作動を変化させる。この構成によれば、加速度Gsに基づいて乗員の移動量を算出し、当該移動量に対応するレベルLを特定し、特定したレベルLに応じて乗員保護装置30の作動を変化させる。そのため、自動ブレーキ11で車両Vが急減速するときでも、乗員の保護を適切に行える。【選択図】図1
