【発明の名称】車両安全装置のための制御システム
Document Type and Number:
Japanese Patent JP2905240
Kind Code:
B2
Abstract:
A control system for a vehicle safety device includes an acceleration sensing circuit, an analog collision detection system, a digital collision detection system, and a drive circuit which operates the vehicle safety device when the drive circuit simultaneously receives collision detection signals respectively from both of the analog and digital collision detection systems. A microcomputer of the digital collision detection system outputs test pulses to the acceleration sensing circuit, and checks at least one of the output of an integrating circuit of the analog collision detection system and an output of a comparator circuit of the analog collision detection system so as to detect a malfunction of the analog collision detection system, the outputs of the integrating circuit and the comparator circuit being produced in response to the test pulse.
