碰撞检测装置
摘要：
本发明获得了一种能够在短时间内判断出向腔室构件的长度方向上的各个部分的碰撞、且可靠性较高的碰撞检测装置。其中，碰撞判断系统(10)具备：腔室构件(20)，其以车宽方向为长度方向且内部被设定为压力腔(22)，并被设置在保险杠加强件(14)的前侧；一对压力传感器(24)，其被配置于在腔室构件(20)的长度方向上分离的位置上，并分别输出与压力腔(22)内的压力变化相对应的信号；碰撞判断用的ECU(26)。ECU(26)在如下情况下判断为发生了碰撞，即，一对压力传感器(24)中的某一个的检测值大于第1阈值，且一对压力检测器中的另一个的检测值大于第2阈值，所述第2阈值相对于所述第1阈值被设定为较大的值。
摘要（英）：

A collision detection device which can determine in a short time a collision to each portion of a chamber member in the longitudinal direction thereof and which is highly reliable. A collision determination system (10) is provided with: a chamber member (20) which is disposed with the longitudinal direction thereof aligned with the vehicle width direction, has a pressure chamber (22) formed therein, and is provided forward of bumper reinforcement (14); a pair of pressure sensors (24) which is provided to the chamber member (20) at positions spaced from each other in the longitudinal direction thereof and outputs a signal corresponding to a variation in the pressure within the pressure chamber (22); and a collision determination ECU (26). The ECU (26) determines that a collision has occurred if the value of detection by either of the pair of pressure sensors (24) is greater than a first threshold value and, at the same time, the value of detection by the other of the pair is greater than a second threshold value which is set to be greater than the first threshold value.
