ABSTRACT:
An inertia sensor system incorporates a vibration-type angular-speed sensor unit and an acceleration sensor unit provided separately. The inertia sensor system also includes a second-type acceleration signal generation unit to extract an acceleration signal component from a detection-object vibration component generated by the vibration-type angular-speed sensor unit and outputs the extracted acceleration signal component as a second-type acceleration signal. An abnormality detection unit detects an abnormality of at least the vibration-type angular-speed sensor unit or the acceleration sensor unit based on the second-type acceleration signal and a first-type acceleration signal detected and output by the acceleration sensor unit.
