Abstract
In a sensor system, a detection waveform-forming unit detects a vibration component and forms a waveform of a detected angular velocity based on the vibration component. Components of the waveform are of opposite phases relative to each other and acceleration waveform components are in phase relative to each other. An acceleration signal-forming unit operates on the waveform to cancel the waveform of opposite phases to each other, and produces a second kind acceleration signal. An abnormal condition-detecting unit detects an abnormal condition in either the angular velocity sensor unit or an acceleration sensor unit provided separately based on the second kind acceleration signal and a first kind acceleration signal.
