Title:
【発明の名称】乗員保護システムのための故障検出装置
Document Type and Number:
Japanese Patent JP2757696
Kind Code:
B2
Abstract:
PURPOSE:To detect abnormality with a high accuracy by detecting the abnormality in the connection sections around a judging means for judging the operation of a starting elements. CONSTITUTION:Abnormality in a resistor 91, comparator 120b, and driving transistor 120c can be detected based on the values resulting from the measured voltages at an end of the resistor 91 for acceleration detecting switches 60 and 70 (voltage measuring point B), and at the terminal of a starting element 20 on its minus side (voltage measuring point C) before and after the time when an abnormality detecting transistor 30 is turned on. For this reason, since not only the abnormality in the components following the output of the comparator 120b, a judging means, but also that in the connection sections of the input part of the comparator 12b can be detected, the abnormality in a driving circuit 120 for starting elements 10 and 20 can be detected with a high accuracy.
