    摘要: A test circuit (100) for an airbag restraint system provides an accurate determination of the operativeness of a storage capacitor (130) and calculates the resistance of inertia switch resistors (114, 118). The capacitor (130) is tested by discharging and charging the capacitor. The values of the inertia switch resistors (114, 118) are determined by switching known resistive values in parallel with the inertial switch resistors. Based on the monitored voltage values during the switching, resistance values are calculated.

    摘要: A test circuit (100) for an airbag restraint system is disclosed and provides an accurate determination of the operativeness of a storage capacitor (130, 132) and calculates the resistance of inertia switch resistors (114, 118). The test circuit provides for parallel testing of the storage capacitor (130, 132) and inertia resistors (130, 132). The capacitor is tested by discharging and charging the capacitor. The values of the inertia switch resistors are determined by switching known resistive values in parallel with the inertia switch resistors. Based on the monitored voltage values during the switching, resistance values are calculated.

    摘要: An apparatus (10) for controlling actuation of a first actuatable restraint (18) and a second actuatable restraint (20) includes a first crash accelerometer (22) for providing a discriminating crash acceleration signal when a crash event is sensed in a first direction and a safing crash acceleration signal when a crash event is sensed in a second direction. A second crash accelerometer (34) provides a safing crash acceleration signal when a crash event is sensed in the first direction and a discriminating crash acceleration signal when a crash event is sensed in the second direction. A third crash accelerometer (90) provides another safing crash signal when a crash event is sensed in either the first or second directions. The first actuatable restraint (18) is actuated when the first accelerometer (22) provides the discriminating crash acceleration signal and either the second or third accelerometers provide a safing crash signal. The second actuatable restraint (20) is actuated when the second accelerometer (34) provides a discriminating crash signal and either the first or the third accelerometer provides a safing crash signal.

    摘要: Circuit de vérification (100) pour système de coussin pneumatique de sécurité qui permet de déterminer de manière précise la capacité de fonctionnement d'un condensateur de mémoire (130) et qui calcule la résistance des résistances de l'interrupteur inertiel (114, 118). La vérification du condensateur (130) s'effectue en le déchargeant et en le chargeant. Les valeurs des résistances de l'interrupteur inertiel (114, 118) sont déterminées en inversant les valeurs de résistance connues en parallèle avec les résistances de l'interrupteur inertiel. Les valeurs de résistances sont calculées à partir des valeurs de tension contrôlées au cours de la commutation.
