Airbag Control Unit and Airbag Control Unit's Diagnosis Method

摘要

The present invention relates to a diagnosis method of the airbag control unit and the airbag control device, according to the airbag control device a sensor for sensing a longitudinal acceleration of the vehicle; And when the predetermined reference input value is set, the longitudinal acceleration signal, and converting the direction of acceleration sensed by the sensor (Xn / Yn) and the predetermined criteria screen acceleration coefficient (Zcc) by using the reference input value a obtained, and whether or not the determination of the direction of the acceleration signal (Xn / Yn) and the air bag deployment based on the criteria whether the screen acceleration coefficient (Zcc) are performed normally, characterized in that it comprises a central processing unit for self-diagnosis. ; As a result, system implementation of the airbag control unit is simplified, reducing costs, and hence the error rate than is expected to be loaded in a small airbag control unit.
