Operating method for detecting an operating status in direct current voltage motor e.g. in passenger safety system in motor vehicle, involves making an analog signal available for an operating status

摘要

An analog signal or a signal (s(t)) depending on the analog signal is scanned so as to make a tracer signal (s(n)) available. A transformation signal (S(k)) is generated from a number of signal values in the tracer signal so as to represent a spectral distribution. The transformation signal is compared with a reference that represents a spectral distribution. Independent claims are also included for the following: (a) A device for detecting an operating status or change in it for a system like a direct current voltage motor; (b) and for a triggering circuit for a direct current voltage motor with connection terminals for attaching a supply voltage.
