Title (EN) COLLISION DETECTING DEVICE
(FR) DISPOSITIF DE DÉTECTION DE COLLISION
(JA) 衝突検知装置
Abstract:
(EN) A collision detecting device is composed of: an acceleration acquiring processing section (11) which acquires output from an acceleration sensor (2); a duration time calculating section (12) which calculates a duration time from a time when an obtained value passes a predetermined value previously set to a time when the value passes the predetermined value again, based on acquired acceleration; and a collision determining processing section (13) which determines collision by comparing the acceleration acquired from the acceleration acquiring processing section (11) with a threshold value.  The collision determining processing section (13) corrects sensitivity of collision determination corresponding to the duration time calculated by the duration time calculating section (12).
(FR) L'invention porte sur un dispositif de détection de collision composé: d'une section de traitement d'acquisition d'accélération (11) acquérant un signal généré par un capteur d'accélération (2), d'une section de calcul de temps de durée (12) calculant une durée entre un instant où la valeur obtenue passe par une valeur prédéterminée établie précédemment et un instant où la valeur passe à nouveau par la valeur prédéterminée, en fonction de l'accélération acquise, et d'une section de traitement de détermination de collision (13) déterminant la collision par comparaison de l'accélération acquise par la section de traitement d'acquisition d'accélération (11) avec une valeur seuil. La section de traitement de détermination de collision (13) corrige la sensibilité de la détermination de collision correspondant à la durée calculée par la section de calcul de durée (12).
(JA)  加速度センサ2の出力を取得する加速度取得処理部11、取得した加速度から予め設定した所定値を通過してから再び通過するまでの継続時間を算出する継続時間算出部12、加速度取得処理部11により取得した加速度と閾値とを比較することで衝突判定を行なう衝突判定処理部13から成り、衝突判定処理部13では、継続時間算出部12より算出した継続時間に応じて衝突判定の感度を補正する。
