Activating device of vehicular passenger protection system |
摘要 |
An activating device for an airbag system is constructed to prevent erroneous activating operation. A microcomputer generates a test signal and applies it to a determination circuit and an inhibition circuit as an inhibition signal. The determination circuit grounds the gate of a switching element which activates an airbag. The inhibition circuit inhibits a switching element from being turned on based on the inhibition signal. In the ON-inhibition state, the switching element is turned on if it is normal with the gate grounded. The switching element remains OFF if it is in malfunction.
