    • A system for controlling an inflation output in an inflatable cushion of an air bag module, comprising: a first sensing device, the first sensing device being an electronic sensing device configured to detect the presence of an object proximate to the air bag module, when the inflatable cushion is in an un-inflated state, the first sensing device providing a suppression signal when an object is detected within an area proximate to the air bag module; a second sensing device, the second sensing device being a mechanical sensing device configured to detect whether a leading edge of the inflatable cushion has made contact with an object prior to the leading edge reaching a predetermined distance from the air bag module during inflation of the inflatable cushion, the second sensing device being disposed within the inflatable cushion and is configured to cause the inflation output provided to the inflatable cushion to be varied when the leading edge of the inflatable cushion has made contact with an object prior to the leading edge reaching the predetermined distance from the air bag module; and a sensing and diagnostic module for receiving the suppression signal and an activation signal, wherein the activation signal corresponds to an event that requires inflation of inflatable cushion in absence of the suppression signal and the sensing and diagnostic module is configured to determine whether the inflation output is to be provided to the inflatable cushion.
    • 一种用于控制气囊模块的充气垫中的充气输出的系统,包括:第一感测装置,所述第一感测装置是被配置为检测靠近所述气囊模块的物体的存在的电子感测装置, 所述充气垫处于未膨胀状态,所述第一感测装置在邻近所述气囊模块的区域内检测到物体时提供抑制信号; 第二感测装置,所述第二感测装置是机械感测装置,其被配置为在所述充气垫的充气期间,在所述前缘到达所述气囊模块的预定距离之前,检测所述可充气衬垫的前缘是否已经与物体接触 所述第二感测装置设置在所述可充气衬垫内,并且被构造成当所述充气垫的前缘在所述前缘达到预定位置之前已经与物体接触时,使提供给所述可膨胀衬垫的所述充气输出变化 距气囊模块的距离; 以及用于接收抑制信号和激活信号的感测和诊断模块,其中激活信号对应于在没有抑制信号的情况下需要充气垫的充气的事件,并且感测和诊断模块被配置为确定充气输出 被提供给充气垫。
