Description
本実施例の乗員保護システムの構成を図1に示した。
以下に、より具体的な乗員保護システム1の動作を説明する。本実施例の乗員保護システム1の動作のフローチャートを図2に示した。
本実施例の乗員保護システム1は、実施例1の乗員保護システムにさらに、上下方向の加速度を検出する上下加速度センサ8と、回転中心算出用ECU9とを備えたシステムである。本実施例の乗員保護システムの構成を図3に示した。
以下に、より具体的な乗員保護システム1の動作を説明する。本実施例の乗員保護システム1の動作のフローチャートを図5に示した。
上記した各実施例の乗員保護システム1は、シートベルトバックルスイッチ、乗員の着座の有無を検出する検出手段、窓の開閉を検出する検出手段、乗員の頭部位置を検出する乗員頭部位置検出手段、乗員の体格を検出する体格検出手段を備えてもよい。これらの手段を備えたときには、これらの手段の検出結果はECU5,6に送信され、乗員の頭部位置の算出やエアバッグ70,71の展開の制御の判定に参照することができる。
