。However, the conventional near backshield device designed to develop J-Ahasoku and detect failures uses a monitor resistor to detect failures; For some reason, the device malfunctioned and the airbag deployed when the vehicle was being driven. That is, in a car, there are many Actanos loads, including Fano, connected to the bending battery 1, and when these load circuits open and close,
It is assumed that a -; This is considered to be because the detonator 10 is detonated through these monitor resistors 11 even though the contacts of the G sensor 8,≦] are open. For this reason, it is conceivable to set the resistance value of the monitor resistor 11 sufficiently large so that the detonator 1o will not explode even if it receives a surge voltage, but the surge voltage itself is not large enough. Low 1 of monitor resistance 11;i
<p'j 'i: If too much attention is paid, the failure detection accuracy will deteriorate, making it necessary to use expensive detection equipment.
