| 摘 要： | 在安全气囊系统(SRS)设计中,需要SRS能够精确感应汽车发生的碰撞,并按照程序判断碰撞事故的严重程度。文章采用滚球式碰撞传感器来检测和判断汽车发生碰撞后的撞击信号。汽车发生碰撞时,滚球式碰撞传感器能根据汽车的速度和加速度大小,自动选择安全带预紧器动作或与安全气囊同时工作,从而避免了气囊的浪费。滚球式碰撞传感器具有结构简单、抗干扰能力好、制造成本低以及使用维护方便等优点,已经成功用于多款车型。

| Abstract: | In Supplemental Inflatable Restraint System(SRS) design,precisely reflecting the vehicle's crash and determining the severe degree is needed.According to the procedures the severity of collision is determined.Adopting crash sensor the crash signal after collision of vehicles is examined and determined.When crash happened the ball-intube crash sensor can automatically select both allowing seatbelt pretensioner and airbag to work at the same time or only using seatbelt pretensioner judging from the vehicles' ... |
