Abstract

PURPOSE: To take out output of a low sensitivity sensor when a high sensitivity sensor is abnormal by processing the input of the high sensitivity sensor at a normal time and processing the input of the low sensitivity sensor at an abnormal time.
CONSTITUTION: An acceleration detector is constituted of a high sensitivity acceleration sensor 2 enhanced in vibration responsiveness, a low sensitivity acceleration sensor 3 planned so that vibration responsiveness is lowered and the max. destruction acceleration is made larger than that of the sensor 2, a high sensitivity acceleration sensor state detection means 110 detecting the abnormality of the vibration sensing part of the sensor 2 and a sensor output processing means 100. The means 100 processes each sensor input on the basis of the state detection signal of the sensor 2 from the means 110 so as to bring the same to sensor output of a predetermined level. At a normal time, the means 100 processes the input of the high sensitivity sensor to take out sensor output and, at an abnormal time when the cantilever beam of the sensor 2 is broken by some impact, the means 100 processes the input of the low sensitivity sensor to take out sensor output of a predetermined level.
